SERIAL PUBLICATIONS OF THE SMITHSONIAN INSTITUTION

The emphasis upon publications as a means of diffusing knowledge was expressed

by the first Secretary of the Smithsonian Institution. In his formal plan for the Institution, Joseph Henry articulated a program that included the following statement:

"It is proposed to publish a series of reports, giving an account of the new discoveries

in science, and of the changes made from year to year in all branches of knowledge."

This keynote of basic research has been adhered to over the years in the issuance

of thousands of titles in serial publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with

the following active series:

Smithsonian Annals of Flight

Smithsonian Contributions to Anthropology

Smithsonian Contributions to Astrophysics

Smithsonian Contributions to Botany

Smithsonian Contributions to the Earth Sciences

Smithsonian Contributions to Paleobiology

Smithsonian Contributions to Zoology

Smithsonian Studies in History and Technology

In these series, the Institution publishes original articles and monographs dealing

with the research and collections of its several museums and offices and of professional

colleagues at other institutions of learning. These papers report newly acquired facts,

synoptic interpretations of data, or original theory in specialized fields. These publications are distributed by mailing lists to libraries, laboratories, and other interested

institutions and specialists throughout the world. Individual copies may be obtained

from the Smithsonian Institution Press as long as stocks are available.

Introduction

During the past ten years many specimens of

Neotropical caddisflies have been studied, most of

which are in the collection of the National Museum of Natural History. Many others, however,

have been submitted by other institutions for identification. Inevitably many undescribed species have

been found in these materials. This paper is presented to provide names for these species so that

this material may be disposed of properly, and to

facilitate future identification of caddisflies in these

two families.

Unless otherwise stated, the material is in the

collection of the National Museum of Natural

History, Smithsonian Institution, under the catalog

numbers of the United States National Museum

(USNM). Other collections are: University of

California, Riverside, California (UCR); Naturhistorisches Museum, Vienna, Austria (Vienna).

The collections from Mexico and Central

America made by the author in 1965-1967 were

made possible by National Science Foundation

grant GB-2616, and the collections from southern

Chile and Argentina were supported by funds from

the U.S. Antarctic Research Program. I am grateful

to my coworkers at the National Museum of

Oliver S. Flint, Jr., Department of Entomology, National

Museum of Natural History, Smithsonian Institution, Washington, D.C. 20560.

Natural History and elsewhere for the many valuable collections that they have placed here.

Family RHYACOPHILIDAE

The Rhyacophilidae are composed of two very

distinct subfamilies. The nominate subfamily is

generally north temperate in distribution and is

not known from the Neotropical Region, whereas

the Hydrobiosinae, to which all the Neotropical

genera belong, is primarily south temperate and

tropical in distribution. The genus Atopsyche is

widespread over most of the region, with the exception of the Chilean Subregion, where it is replaced by a swarm of genera. A few of these genera,

however, penetrate into the area occupied by

Atopsyche. See Flint (1963 and 1971) for keys to

the Neotropical genera.

The larvae are all free-living, and apparently

primarily predaceous. They live in fast-flowing,

and generally, cool water, which limits their distribution to hilly or mountainous areas.

Genus Atopsyche Banks

This genus is known from the southwestern

United States, Mexico and Central America, the

Greater Antilles, and in South America south into

the Province of Catamarca in Argentina. There

1
SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY

are numerous species in the genus, 46 having been

described previously to the 10 herein described.

Few, however, are known from enough localities to

give a clear indication of their overall geographic

range.

The larvae are well known, those of a number

of species having been described (Flint, 1963,

1971, etc.).

Atopsyche talamanca, new species

FIGURES 1-3

This species is a member of the tripunctata group

and is very closely related to A. cira (Mosely). In

A. cira the paracercus is simply trianguloid with

basodorsal and apicoventral angles; in A. talamanca the basodorsal angle is developed into a

long, rounded lobe, and the apicoventral angle is

produced farther ventrad. The dorsal spur on the

aedeagus is considerably longer in A. talamanca

and borne from nearer midlength.

ADULT.—Known from pharate adults only; forewing length not precisely known but estimated at

10 mm. Color unknown. Male abdomen with anterolateral angles of second and third terga narrowly produced; anterolateral process of fifth

sternum slightly longer than sternum; posteromesal process of sixth and seventh sterna about

two-thirds length of respective sterna. Male genitalia: Ninth segment broad laterally; tenth tergum

typical. Paracercus with a large, rounded, erect

lobe dorsally, with a pointed apicoventral lobe

bearing a small point. Filicercus slender, elongate;

cercus button shaped. Clasper with basal segment

enlarged apicad, with a slender mesal process;

apical segment broad basally, narrowed apically,

dorsal margin slightly enrolled. Aedeagus with

basal area large; apicolateral lobes thin and broad,

each with a dorsal spine at midlength; with a

central spine.

Paratype: Same data, 1 $ .

Atopsyche huenga, new species

FIGURES 4-5

Atopsyche calopta Ross, A. hispida Denning, and

A. huenga, new species, form a very closely related

group of species hardly differing in shape of paracercus, filicercus, or aedeagus. From its congeners

A. huenga may be easily recognized by the elongate

apical segment of the clasper which, in ventral

aspect, has its tip bidentate.

ADULT.—Length of forewing 7 mm. Color brown,

bases of legs yellowish; forewing dark brown, with

irregular tufts of brighter hairs. Male abdomen

with anterolateral process of fifth sternum one and

one-half times as long as sternum; apicomesal

process of sixth sternum one and one-half times

as long as sternum, that of seventh sternum as

long as sternum. Male genitalia: Ninth segment

narrow laterally; tenth tergum typical. Paracercus

broad, inflated, rounded apically, with a small middorsal reflexed point. Filicercus rodlike, but short,

and tipped by a large seta; cercus buttonlike.

Clasper with basal segment about twice as long

as broad, constricted basally; apical segment broad,

about as long as basal segment, in ventral aspect

with tip bidentate. Aedeagus short, with a pair of

curved dorsal spines and broad lateral plates; a

curved internal spine.

Atopsyche caquetia, new species

FIGURES 6-8

This species is clearly a member of the kingi

complex, but is easily distinguished from the other

members of the complex by the narrow, upturned

apex of the paracercus, the hooked ventral process

of the aedeagus, and the seta-bearing process at

the apex of the clasper.

ADULT.—Length of forewing 7 mm. Color brown,

legs yellowish; forewing mostly brown, with flecks

of darker and paler brown hair. Male abdomen

with anterolateral angle of second tergum narrowly produced, angles of third and fourth terga

produced and enlarged apically, third and fourth

terga with an ovoid depression anterolaterally

bearing many small setae; fifth sternum with anterolateral process hardly longer than broad; apicomesal process of sixth sternum about as long as
NUMBER 169

sternum, that of seventh sternum about two-thirds

as long as sternum. Male genitalia: Ninth segment

slightly enlarged laterally; tenth tergum with transverse ridges basally. Paracercus broad basally, tapering abruptly to a dorsally directed apical hook,

with a dorsomesal pointed process. Filicercus very

long, slightly enlarged apicad; cercus a small lobe.

Clasper with basal segment distinctly enlarged

apicad, with a large apicomesal pointed process;

apical segment elongate, gently tapering, apex with

a small reflexed lobe bearing a brush of enlarged

setae. Aedeagus with a small rounded base; ventrally with a pair of hooklike processes; a pair of

slender elongate dorsal processes bearing basolaterally a short spine and dorsoapically bidentate;

with a long, slender internal spine.

Atopsyche choronica, new species

FIGURES 9-11

The species appears to fit best into the kingi

complex, although it differs from all other species

in possessing only a single pair of sacs in the abdominal terga and in possessing a pair of dorsal

rods on the aedeagus.

ADULT.—Length of forewing 6.5-7 mm. Color

brown, legs yellowish; forewing brown, flecked

with black and golden hairs. Male abdomen with

anterolateral angle of second tergum narrowly

produced, that of third tergum elongate and enlarged apically, third tergum with a large internal

pouch anterolaterally; fifth sternum with a small

knob dorsolaterally; sixth sternum with posteromesal process slightly longer than sternum, that

of seventh sternum two-thirds length of sternum.

Male genitalia: Ninth segment slightly enlarged

laterally; tenth tergum typical. Paracercus rather

short, with a basolateral shoulder, with a subapical

point directed dorsolaterad and a dorsoapical point.

Filicercus very long, slender, apex enlarged; cercus

small, buttonlike. Clasper with basal segment long,

curved, ventral margin expanded at midlength;

apical segment slender, tip produced into a small

point. Aedeagus with base short, bearing a pair

of slender, arched, and curved spines from dorsum;

apex of lateral lobe produced into a sharp point,

bearing a membranous process tipped by a sharp

spine; with a slender pointed internal rod.

Atopsyche weibezahni, new species

FIGURES 12-14

This species seems to be most closely related to

A. choronica, new species, with which it agrees in

possessing nonarticulated, dorsal processes from

the aedeagus, and in the general structure of the

aedeagus and claspers. There are considerable differences in the shapes of the various structures,

however, especially that of the paracercus.

ADULT.—Length of forewing unknown, but probably about 7 mm. Color unknown. Third and

fourth abdominal terga with anterolateral pouches;

fifth sternum with anterolateral process about twice

as long as broad, with a posteromesal process about

half length of sternum; sixth sternum with posteromesal process slightly longer than sternum,

that of seventh sternum about half length of sternum. Male genitalia: Ninth and tenth segments

typical. Paracercus with a large, erect, middorsal,

pointed, and somewhat irregular lobe, with ventral

margin rolled laterad, and with an irregularly

rounded apical lobe rolled lateral and dorsad.

Filicercus long and slender; cercus buttonlike.

Clasper with basal segment very long, dorsal margin slightly sinuate; apical segment fingerlike, directed posteromesad, with a row of mesal setae,

dorsal margin slightly inrolled. Aedeagus with base

large, rounded, bearing a single dorsomesal process, whose tip is slightly twisted; lateral lobe with

a basolateral expansion, apex with a small dorsal

spur and a ventral lobe bearing spicules mesally;

with a slender internal spine.

SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY

Atopsyche taina, new species

FIGURES 15-17

This species is clearly a member of the West

Indian batesi group and probably closest to A.

cubana Flint. From this and all other species of

the group, it is easily recognized by the presence

of two pairs of lateral spines on the aedeagus, the

shape of the paracercus, and the shape of the apical

segment of the clasper.

ADULT.—Length of forewing 6.5—8 mm. Color

light brown, legs yellowish; forewing mostly brown,

with irregular lighter and darker marks, with a

triangular darker mark basally from the costa. Male

abdomen with third and fourth terga impressed

along anterior margin and bearing numerous short

setae; fifth sternum with anterolateral process

about twice length of sternum; apicomesal process

of sixth sternum about length of sternum, that of

seventh sternum about two-thirds length of sternum. Male genitalia: Ninth segment with posterolateral margin produced; tenth tergum typical.

Paracercus with tip produced into a short, dorsally

directed hook. Filicercus long and slender; cercus

buttonlike. Clasper with basal segment slightly

inflated at midlength, apex produced into a slender,

dorsal lobe, slightly shorter than apical segment,

which is a rather simple pointed lobe. Aedeagus

with base large; bearing an articulated dorsal

process; with 2 pairs of ventrally directed spines

at midlength; divided apically, with tips slightly

divergent; with a slender central spine.

MATERIAL.—Holotype, male: DOMINICAN REPUBLIC: Convento, 12 km S of Constanza, 6-13

Paratype: 12.5 km S of Loma de Cabrera, 23 May

1973, M. and D. Davis, 1 $ .

Atopsyche conventica, new species

FIGURES 1&-20

This species is a distinctive member of the batesi

group, close to A. cubana Flint. It differs most

noticeably in the paracercus, with its very broad

base and narrow, rounded apex, and in the trifid

apex of the lateral lobes of the aedeagus.

ADULT.—Length of forewing 8 mm. Color dark

brown, legs yellowish; forewing darker basally, but

with a semicircular pale area in anal region, remainder irregularly flecked with paler and darker

marks. Male abdomen with third and fourth terga

impressed along anterior margin and bearing numerous short setae; fifth sternum with anterolateral

process almost twice as long as sternum; sixth

sternum with posteromesal process as long as sternum, that of seventh sternum about one-third

length of sternum. Male genitalia: Ninth segment

broad laterally, with posterior margin expanded

into a thin plate; tenth tergum typical. Paracercus

broad basally, narrowed into an elongate hoodlike

apex. Filicercus long and slender; cercus elongate,

apex rounded. Clasper with basal segment widened

apicad, with a small apicoventral lobe, and a long,

hooked apicodorsal lobe; apical segment slightly

longer than apicodorsal lobe, widened subapically,

with a small, pointed lobe on mesal face. Aedeagus

with base elongate, with an articulated dorsal rod;

lateral lobes apically produced into 3 small lobes;

with a central spine.

Paratype: Same data, 1 $ .

Atopsyche davisorum, new species

FIGURES 21-23

In spite of the lack of articulated dorsal process

on the aedeagus, I believe that this species is closely

related to A. batesi Banks. The similarities in

shapes of the claspers and paracercus are quite

striking in the two species. The presence of a

filicercus in A. davisorum may indicate that this

structure is broken off in the only known specimen

of A. batesi. Additional differences are found in

the shapes of the dorsal process of the basal segment of the clasper, the paracercus, and the lateral

plate of the aedeagus.

ADULT.—Length of forewing 7 mm. Color light

brown, legs yellowish; forewing mostly pale brown,

with scattered dark spots, with a triangular dark

mark basally from costa. Male abdomen with third

and fourth terga impressed anteriorly and bearing

numerous short setae, anterolateral angle of third

tergum elongate and with a small, impressed setate

pocket; anterolateral process of fifth sternum one

and one-half times length of sternum; posteromesal

process of sixth sternum barely longer than ster-

num, that of seventh sternum about one-third

length of sternum. Male genitalia: Ninth and tenth

segments typical. Paracercus short, tapering rapidly,

with small points middorsally and apically, directed primarily laterad. Filicercus long, inflated

apically; cercus buttonlike. Clasper with basal segment almost parallel sided, slightly curved, with

a small apicodorsal lobe; apical segment almost

quadrate. Aedeagus with base short, tapering to

a rounded apex; lateral plates broad, apex strongly

flared laterad; with a central spine.

Atopsyche zernyi, new species

FICURES 24-26

This species is closely related to A. hamata Ross.

From the latter it differs in possessing a broader

paracercus, bearing several spines dorsally at midlength, and in the structure of the apical part of

the aedeagus, which bears only an apical and

lateral spine.

ADULT.—Length of forewing 6.5 mm. Color

brown, forewing irregularly marked with various

shades of brown. Male abdomen with a pouch internally from posterolateral angle of second tergum

and a similar pouch from anterolateral angle of

third tergum; fifth sternum with anterolateral

process about half length of sternum; posteromesal

process of sixth sternum about as long as sternum,

that of seventh sternum about half as long as sternum. Male genitalia: Ninth and tenth segments

typical. Paracercus broad, upper margin deflected

slightly laterad, bearing several reflexed points at

midlength, apex narrowed, obliquely truncate.

Filicercus long; cercus buttonlike. Clasper with

basal segment elongate, parallel sided, about three

and one-half times as long as broad, with a thin

apicomesal process slightly shorter than apical segment. Aedeagus with basal portion rounded, elongate; with a midventral process articulating with

clasper bases and a middorsal hood; with elongate

lateral lobes, each ending in a membranous, upturned section, bearing apical and lateral spines;

with a long, slender central spine.

Atopsyche sanctipauli, new species

FIGURES 27-29

On the basis of the raesal position of the apical

process of the basal clasper segment, this species

should be placed in the longipennis group. In this

group, the only species with a dorsal process on

the aedeagus is the Mexican A. japoda Ross.

Atopsyche sanctipauli, however, is immediately

recognized by the forked lateral process of the

aedeagus, the different shapes of the paracercus,

and the apical parts of the claspers.

ADULT.—Length of forewing 7 mm. Color brown,

legs yellowish; forewing brown, with indication

of lighter and darker mottling. Male abdomen

with internal pouches from anterolateral angles of

third and fourth terga; fifth sternum with only a

slight knob anterolaterally; posteromesal process

of sixth sternum as long as sternum, that of seventh

sternum two-thirds as long as sternum. Male genitalia: Ninth segment narrow laterally; tenth tergum typical. Paracercus developed into a basally

directed dorsal crest, bearing a short, pointed, lateral process near base and another near apex,

apical portion narrowly produced, tip upturned

and bearing 3 small points. Filicercus lacking

(broken off?); cercus a small, rounded lobe. Clasper

with basal segment long, parallel-sided, bearing a

small lobe from mesal face, apicoventral process

thin, bilobed in ventromesal aspect; apical segment

broad basally, apex thin, produced and curved so

as to cover apicoventral process. Aedeagus with

base short, bearing a nonarticulated dorsal process;

lateral lobes thin, with a narrow dorsolateral

flange, laterally with a thin, deeply bifurcate lobe,

with a long, slender, central spine.

Genus Australochorema Schmid

The species described below is only the second

species to be discovered in the genus. The species

are known only from within the Chilean Subregion.

The immature stages have not been described.
SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY

Australochorema brachy tergum, new species

FIGURES 30-31

This, the second species described in Australochorema, is closely related to the type-species, A.

rectispina Schmid. The short and deflexed lobes

of the tenth tergum are the most conspicuous

differences in A. brachytergum, but the clasper,

with its ventral process, rounded apical lobe, and

straight second segment, is also diagnostic.

ADULT.—Length of forewing 7 mm. Color dark

brown, legs paler basally; forewing dark brown,

with scattered white flecks, an oblique white mark

from posterior margin at midlength especially conspicuous. Male abdomen with fifth sternum bearing a short, membranous process dorsolaterally;

sixth sternum with posteromesal process half length

of sternum, seventh sternum with a short, broad,

naillike posteromesal lobe. Male genitalia: Ninth

segment broadened laterally. Tenth tergum with

anterior margin very oblique, apical lobes short

and deflexed. Filicercus very long and slender,

apices curved mesad; cercus short and slender.

Clasper with basal segment elongate, apex rounded,

in ventral aspect with mesal margin tapering from

base, with a thumblike process; apical segment

borne middorsally from mesal face, elongate, with

a row of ventral points. Aedeagus tubular, with

an apicoventral lip and a small internal sclerite.

Genus Rheochorema Schmid

The species herein described brings to four the

number of species placed in Rheochorema. All

species are known exclusively from the Chilean

Subregion.

The larva of R. lobulifera Flint was described

by Flint (1967).

Rheochorema magellanica, new species

FIGURE 32

This species is clearly related to R. tenuispina

Schmid but, in its development of the processes

from the bases of the claspers, represents a more

highly evolved condition. Rheochorema magellanica may be distinguished by the shape of the

apical segment of the clasper, the very long basal

process of the clasper that is mostly covered by

a dorsal extension of the aedeagus, which bears

a very short apicomesal process, and in the shape

of the basal area of the tenth tergum.

The larvae of this species agree, except for a

more distinct color pattern on the head, with those

of R. lobulifera Flint.

ADULT.—Length of forewing IS mm. Color

brown; forewings pale brown, with a few small

golden flecks, anal area with an irregular whitish

area bounded by fuscous. Abdomen without processes. Male genitalia: Ninth segment almost rectangular in lateral aspect. Tenth tergum with a

complex, convoluted sclerotized region basolaterally, giving rise to a membranous lobe; dorsally

with ventral surface sclerotized and striate. Cercus

small and inconspicuous; filicercus long, davate.

Clasper two segmented: basal segment about twice

as long as broad, with a basoventral process that

is very long and slender, becoming dorsally channeled by flaps on the aedeagus and extending from

apicodorsal section of the aedeagus, with a second

basodorsal lobe articulating with basoventral process of aedeagus; apical segment with a triangular

basal flap directed dorsomesally and a rodlike

apical lobe. Aedeagus long, slender; with a dorsal,

hooklike sclerite at midlength, with a long, dorsolateral flap and a shorter apicoventral flap, serving

to form a groove to direct basoventral process of

clasper, apex with ventromesal process short.

Family GLOSSOSOMATIDAE

In the New World, two subfamilies of Glossosomatidae are found, the nominate and the Protoptilinae. The Glossosomatinae are found only

as far south as the highlands of central Mexico,

whereas the Protoptilinae are found over all the

Americas as far north as southern Canada. The

reader is referred to Flint (1963 and 1971) for
NUMBER 169

keys to the genera of Protoptilinae and to Ross

(1956) for keys to the Glossosomatinae.

The larvae construct a case of small sand grains

in the form of a turtle's shell. They appear to be

primarily grazers on the periphyton on the rocks

in flowing, cool water. Undoubtedly for this reason,

they are commonest in the hilly and mountainous

regions, although some are known from the center

of the Amazon Basin.

Genus Antoptila Mosely

The species described below brings to three the

species placed in Antoptila. All the species are

known only from Brazil.

The immature stages are unknown.

Antoptila plaumanni, new species

FIGURES 33-34

This species is related to A. brasiliana Mosely,

from which it differs in aspects of its venation and

genitalia. The venation differs from that of A.

brasiliana in that both R2+8 and R 4+6 branch at

r in the forewing, and there are small apical forks

in M 1+2 and Cu! in the hind wing. In venation,

A. plaumanni thus agrees with the Chilean genus

Mastigoptila; however, the two genera may still

be held apart by the marked asymmetry in the

aedeagal complex of Mastigoptila.

In genitalic characteristics A. brasiliana and A.

plaumanni are very similar, the main differences

being in the ventral aspects. In A. brasiliana the

ninth sternum bears basally two pairs of slender,

almost setalike processes, whereas A. plaumanni

bears one pair of broader processes basally from

the aedeagal complex.

ADULT.—Length of forewing 2.5-3 mm. Color of

alcoholic specimen uniformly brown. Sixth sternum with a pointed mesal process. Male genitalia:

Ninth segment oblique in lateral aspect, with anterior margin rounded. Tenth tergum apically

truncate, lateral margin bearing a posteriorly directed spine and a small ventrolateral lobe. Aedeagal complex bearing basoventrally a pair of long,

slender, slightly twisted processes; complex rather

simple, with a narrow midregion beyond which it

rapidly enlarges to a broad dorsal hood, bearing

a lateral, posteriorly directed tooth and ventrally

a membranous lobe.

Genus Cariboptila Flint

The species of this genus have been taken only

on the Greater Antillean islands. Previously one

species was known from Puerto Rico and one from

Jamaica.

The immature stages of both the Puerto Rican

and Jamaican species were described (Flint 1964,

1968).

Cariboptila aurulenta, new species

FIGURES 35-37

The structure of the genitalia of this species

suggests a rather close relationship to the typespecies, Cariboptila orophila Flint. It may be distinguished by the tenth tergite, with its elongate

lobe, and the aedeagal complex, which is much

shorter and with differently shaped apicomesal

lobes.

ADULT.—Length of forewing 2.5-3 mm. Color

brown; forewing with golden-brown hair in anal

region, with an irregular white, transverse band

at anastomosis and in small spots around apex;

fore and hind wings with a fringe of long, golden

hair in posteroapical area. Male with basal antennal segment long and slightly compressed; sixth

sternum with a flattened, rounded, apicomesal

process. Male genitalia: Ninth tergum in lateral

aspect very narrow, with an arched dorsomesal

lobe; with dorsolateral process very short and

tipped by a large seta. Tenth tergite consisting

ot a fingerlike dorsolateral lobe, a rounded ventral lobe with several curved spines, a small setatipped dorsal process, and a thin mesal plate.

Aedeagal complex with 2 pairs of dark internal

spines; lateral plate with dorsolateral angle prolonged and tipped by a large seta, ventral margin

cut away at midlength, and with apex truncate;

Cariboptila hispaniolica, new species

FIGURES 38-40

This species is placed in Cariboptila, with which

it agrees in venation, although the male genitalia

are quite different from the previously known

species. The large lateral lobe on the ninth tergum

is distinctive, as are the shape and structure of

the aedeagal complex.

ADULT.—Length of forewing 3.5 mm. Color

brown; forewing brown, with an indication of

white hairs along anastomosis and in spots along

posterior margin apically. Sixth sternum with a

broad, mesal, naillike lobe, whose apex is bilobate.

Male genitalia: Ninth tergum nearly circular in

outline in lateral aspect, posterior margin bearing

laterally a large truncate lobe beneath tenth tergite; in posterior aspect with a mesal structure

bearing a pair of slender curled processes and a

pair of long ventral rods. Tenth tergite set into

a deep pocket in posterior margin of ninth tergum, bearing several slender processes tipped by

enlarged setae, and pointed and rounded lobes.

Aedeagal complex with lateral plate apically upturned, with apicolateral margins expanded laterad,

and bearing basolaterally a short lobe; internally

with a pair of trilobate sclerites dorsally, laterally

with a cluster of 3 short spines, and a pair of

longer spines ventrally; with short basolateral

lobes.

Cariboptila calcigena, new species

FIGURES 41-43

Although at first sight this species would appear

to be a species of the genus Glossosoma (Ripaeglossa), this is a case of remarkable convergence

in two distinct subfamilies. The large lateral flap

of the ninth segment expresses an extreme development of the condition foreshadowed in C. hispaniolica. The male genitalia of the two species are easily

homologized, but differ greatly in the form of

every part.

ADULT.—Length of forewing 3.5-4 mm. Color

brown; forewings with some white hair at anastomosis, especially at posterior margin, and with

small white flecks along apical margin. Sixth sternum with a thin naillike apicomesal lobe. Male

genitalia: Ninth tergum very broad in lateral aspect, with posterior margin produced as a large

rounded flap, with apicomesal face bearing a pad

of fine hairs; with dorsolateral lobes long and

rodlike. Tenth tergite in lateral aspect obscured

by lobes of ninth tergum; in posterior aspect elongate, with enlarged setae and pointed and rounded

lobes apically; a V-shaped sclerite, with enlarged

setae mesally dorsad of tergites. Aedeagal complex

ventrally with a pair of long rodlike structures

projecting posteriad; internally with a pair of long

spines whose tips are curved mesad beneath central

tube; apicoventrally with a pair of slender, lightly

sclerotized lobes; internally with a membranous

tube, bearing many short dark spines; with basolateral winglike lobes, which loosely attach entire

structure to venter of ninth tergum.

Genus Culoptila Mosely

The genus was originally established for four

Mexican species; since then three species have

been described, one from Guatemala, and two

from the southwestern United States.

The immature stages have not been described.

Culoptila nahuatl, new species

FIGURES 44-45

This species is very closely related to C. saltena

Mosely, but differs in lacking the pair of dorsal

points from the tenth tergum, and in having a

more bulbous outline to the aedeagus, which contains two long internal spines.
NUMBER 169

ADULTS.—Length of forewing 2.5 mm. Color

brown; forewing brown, slightly paler along anastomosis. Sixth sternum of male with a compressed

apicomesal knob. Male genitalia: Ninth tergum

narrowed ventrad. Tenth tergum in lateral aspect

with dorsal margin produced into a point, ventral

arms rounded apically, each bearing 2 stout anterior setae; in posteroventral aspect with dorsal

margin nearly straight, apex of ventral arms obliquely truncate. Venter of capsule slightly produced posteriad, in posteroventral aspect composed

of a pair of trianguloid sclerites. Aedeagus a large

internal sac, bearing 2 spines more than half filling

sac, apicodorsal angle produced into a pointed

Culoptila tarascanica, new species

FIGURES 46-47

This species is most closely related to C. saltena

Mosely, although the posterior lobes of the ninth

sternum are suggestive of C. amberia Mosely. From

C. saltena, C. tarascanica differs in the broader,

longer posterior lobes of the ninth sternum, and

in having much shorter internal rods in the

aedeagus.

ADULT.—Length of forewing 3 mm. Color brown;

forewing with a slight indication of a pale band

at anastomosis. Sixth sternum of male with a compressed apicomesal lobe. Male genitalia: Ninth

tergum narrowed ventrad. Tentli tergum in lateral

aspect with dorsal margin produced into a point,

ventral arms obliquely truncate, each bearing 2

anteriorly pointing setae; in posteroventral aspect

with dorsal margin produced into a pair of small

sublateral points, apex of ventral arms with tips

darkened and slightly incurved. Venter of capsule

produced into a large, rounded lobe in lateral

aspect; in ventral aspect composed of a pair of

obliquely truncate lobes. Aedeagus a large internal

sac bearing 2 spines, no more than a third filling

sac, one spine very lightly sclerotized, with apex

bluntly hooked; apicodorsal angle produced into

a pointed hood, apicoventrally with a complex of

structures.

Culoptila costaricensis, new species

FIGURES 48-49

This species is very close to C. amberia Mosely,

as evinced by the shape of the tenth tergum, broad

apex of the aedeagus, and length of the aedeagal

spines. It differs in the shape of the posterior

processes from the venter of the genital capsule,

which in C. amberia are long, broad, and slightly

enlarged apicad, rather than short and narrow.

ADULT.—Length of forewing 3.5 mm. Color in

alcohol dark brown. Sixth sternum of male with a

compressed, apicomesal knob. Male genitalia:

Ninth tergum narrowed ventrad. Tenth tergum

in lateral aspect rather blunt apically, with ventral

arms directed ventrad, tip obliquely truncate; in

posteroventral aspect with dorsal margin nearly

straight, inner tip of ventral arms pointed. Venter

of capsule produced into a pair of short, narrow

lobes, separated by a V-shaped incision in posteroventral aspect. Aedeagus a large internal sac with

nearly parallel dorsal and ventral sides, with 2

long internal spines more than half filling sac;

apicodorsal margin produced into a long, rather

broad hood, in posteroventral aspect with a

Y-shaped thickening; ventrally with a complex of

Genus Mastigoptila Flint

The following species differs considerably from

the six previously described species of this genus.

All known species are restricted to the Chilean

Subregion.

The larvae and pupae have not been described.

Mastigoptila ecornuta, new species

FIGURES 50-51

This species differs in genitalic structure rather

radically from the other known species of the

genus, yet because the venation is identical and
10 SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY

the genitalia offer some similarities to the other

species of the genus, I am not erecting a new genus

for its reception. The lack of processes from the

tenth tergum, and the presence of a pair of ventral

arms, two internal spines, and a whip on the right

side of the aedeagal complex, render the genitalia

very distinctive.

ADULT.—Length of forewing 4 mm. Color fuscous; forewing fuscous, with a pale mark on posterior margin at midlength. Fifth sternum with

small, lateral flaps connected across venter by a

dark line; sixth sternum produced into a short

posteromesal point. Male genitalia: Ninth segment

narrow laterally; produced into a broadly triangular lobe ventromesally and bearing from its apex

a terete process. Tenth tergum hoodlike, posterior

margin irregular, without processes. Aedeagal complex ventrally with a pair of slightly curved arms,

ending in a twisted tip; with a dorsomesal sclerotized cover; central tube bearing a pair of heavily

sclerotized, curved spines apically, and on right

side a rounded knob, which forms a channel for

the whip that is born basomesally and curved to

the right side of the central tube.

Genus Mexitrichia Mosely

The following eight species bring to twentytwo the number of species described in Mexitrichia. Species are known throughout Mexico and

Central America, Trinidad, western South America

as far south as southern Peru, and in eastern South

America in the hilly region of south Brazil and

adjacent Argentina and Paraguay.

The immature stages were described by Flint

(1963).

Mexitrichia rovira, new species

FIGURES 52-53

This species clearly belongs to the leroda group,

and is probably most closely related to M. leroda

Mosely. From this species, M. rovira differs in lacking all processes from the venter of the aedeagal

complex, and in possessing a large spine internally

in the aedeagus.

ADULT.—Length of forewing 2.5 mm. Color in

alcohol brown. Sixth sternum with a short, compressed mesal process. Male genitalia: Ninth segment rounded anteriorly. Tenth tergum in lateral

aspect produced into a darkened apical point, and

a small ventrolateral lobe; in dorsal aspect with

a broadly U-shaped apicomesal excision. Aedeagal

complex with a dorsomesal process, whose tip is

slender and upturned, and a pair of long, slender

lateral appendages, which are widened subapically

and end in a sharp point; central tube apicodorsally produced into a sharp point, with an internal,

apical sclerite curled in lateral aspect; basoventrally with a pair of short, rodlike appendages and

a small, thin, curved plate, whose apical margin

is slightly bilobed in ventral aspect.

Mexitrichia florica, new species

FIGURES 54-55

Mexitrichia florica is closely related to M. rancura

Mosely, from which it differs in possessing lateral

appendages that are much longer than the aedeagus, and in the shape of the central tube of the

aedeagus, especially its lateral channel.

ADULT.—Length of forewing 3 mm. Color in

alcohol brown; forewing with an indication of

a pale band at anastomosis. Sixth sternum with a

short, compressed mesal process. Male genitalia:

Ninth segment rounded anteriorly. Tenth tergum

in lateral aspect with a pointed apicodorsal process,

a pointed and darkened lateral lobe, without a

ventrolateral lobe; in dorsal aspect with a conical

mesal process, and rounded lateral lobes. Aedeagal

complex with a dorsomesal process that is straight

and pointed apically, and a pair of very long,

slender lateral appendages, whose ends are annulate; central tube with a large apical spine,

and bearing laterally from dorsal margin a narrow, arched lobe and from lateral margin, an

oblique, narrow, elongate plate, between which

the lateral appendages ride; basoventrally with a

Genus Protoptila Banks

The species herein described bring to over 50

the number of species placed in Protoptila in the

being known from the United States. With the

exception of the Greater Antilles (a species is

known from the Lesser Antilles) and the Chilean

Subregion, species are known from throughout the

New World from southern Canada to northern

Argentina.

The immature stages of several species have been

described (Ross 1944, Flint 1963). The larvae seem

to be more tolerant of warmer and slower flowing

waters than most of the others in the family, undoubtedly contributing greatly to the wide distribution of this genus.

Protoptila orotina orotina, new species

and new subspecies

FIGURE 69-70

This species is very close to Protoptila ixtala

Mosely, with which it is frequently found. It

differs primarily in the apex of the ninth sternum,

which is only shallowly bifid in P. o. orotina,

whereas the posterolateral angles are greatly prolonged in P. ixtala. In addition, the apex of the

tenth tergite bears a short point, the apex of the

central tube of the aedeagus is prolonged, and the

lateral aspect of the eighth sternum is slightly

different in the two species.

ADULT.—Length of forewing 3 mm. Color in

alcohol brown, with an indication of a pale transverse band at anastomosis. Sixth sternum with a

compressed, apicomesal process. Male genitalia:

Eighth sternum produced as a long, slender process, with a very slightly bifid apex. Ninth sternum

produced for about half length of eighth sternum,

with posterior margin broadly and shallowly emarginate. Tenth tergite composed of a rectangular

basal section, with a slender elongate, decurved

apical section ending in a small central point.

Aedeagus with a large, mesal, basodorsal lobe, a

pair of ventral rodlike appendages; with long,

lateral appendages arising from membranous bases

The tip of the aedeagus in P. o. raposa is produced

that in posterodorsal aspect the tip is emarginate

rather than produced. In all other parts I am unable to find any consistent differences.

Protoptila colombiensis, new species

FIGURE 73

This species seems to be related to P. ixtala

Mosely. It is recognized by the bifid apex of the

eighth sternum, the shorter apex and larger lateral

spines of the aedeagus, and differently shaped tenth

tergum.

ADULT.—Length of forewing 2 mm. Color brown

in alcohol, with an indication of a pale transverse

band along anastomosis. Sixth sternum with a

compressed, apicomesal point. Male genitalia:

Eighth sternum greatly prolonged into a narrow,

apically bifid process. Ninth sternum prolonged,

thin, apex shallowly bifid in ventral aspect. Tenth

tergite with basal section slightly longer than

broad; apical section elongate, parallel sided,

slightly bowed, apex shallowly bilobed. Aedeagus

with typical basal lobes, and midlength complex

bearing an elongate pointed process; with lateral

arm membranous basally, giving rise to a long,

slightly curved apical spine; central tube narrow,

arched, apex enlarged, scoop shaped.

Protoptila talamanca, new species

FIGURE 74

This species clearly is related to P. resolda

Mosely. It differs rather strikingly by the greatly

produced and forked posterolateral processes of

the ninth sternum.

ADULT.—Length of forewing 3 mm. Color brown,

forewing with an indication of a pale band along

the anastomosis. Sixth sternum with a compressed

apicomesal process. Male genitalia: Eighth sternum

produced as a long, slender posteromesal lobe.

Ninth sternum with posterolateral angles produced

into long, slender, forked processes. Tenth tergite

with a small basal section; apical section decumbent, rectangular, with a small posteroventral

point. Aedeagus with usual basal and mesal processes and lobes; with lateral process bearing a long,

twisted apical spine; central tube only slightly

angled, enlarged apicad, with dorsal margin of

apicolateral sclerite reflexed.

Protoptila spirifera, new species

FIGURE 75

This species also seems to be related to P. resolda

Mosely, although less closely so than the preceding. The apical spine of the lateral process of the

aedeagus is very strongly twisted, and the apex of

the central tube of the aedeagus is more slender

and simpler in structure in P. spirifera.

ADULT.—Length of forewing 4 mm. Color dark

brown; forewing dark brown, with golden hair

along posterior margin and in spots around apex.

Sixth sternum with a pointed mesal process. Male

genitalia: Eighth sternum with posterior margin

produced into a long, slender mesal process. Ninth

sternum produced into a slender posteroventral

lobe. Tenth tergite with an elongate, rectanguloid

basal section; apical section elongate, apex

rounded, with a sharp mesal tooth. Aedeagus with

typical basal processes; with a lateral process arising from a basal membranous section, apical spine

long, sharply twisted; central tube slender, evenly

curved, apex slightly enlarged, with an internal

spine.

Protoptila huava, new species

FIGURE 76

This species has no clear affinities within the

genus, beyond the fact that it belongs to Mosely's

group 1. The short eighth sternum, with its dorsolateral appendage, is unique as is the shape of the

tenth tergite.

ADULT.—Length of forewing 2 mm. Cleared and

in alcohol, color light brown. Antenna with 4 basal

segments typical, segments 5 and 6 enlarged and

flattened, with small rounded setae on mesal face

(broken off beyond segment 6). Sixth sternum

with a pointed apicomesal process. Male genitalia:

Eighth sternum produced as a broad, scoop-shaped

lobe, with a small dorsolateral fingerlike process.

Ninth sternum produced within eighth, and ending

in a small mesal lobe. Tenth tergite with a small

quadrangular basal section; apical section angulate,

ending in a flattened bifid plate directed posteromesad. Aedeagus with typical basal and mesal

lobes; with a lateral process ending in a long,

slender, curled spine; central tube simple, arched,

enlarged apicad, with a small internal spine subapically.

Protoptila quicha, new species

FIGURE 77

The form of the aedeagus in this species is suggestive of that of P. techila Mosely, but the eighth

and ninth sterna and tenth tergite are totally

different in the two species.

ADULT.—Length of forewing 4.5 mm. Color

brown; forewing whitish along anastomosis. Sixth

sternum with a pointed, compressed posteromesal

process. Male genitalia: Eighth sternum produced

posteromesally, upcurved apically, with apex truncate. Ninth sternum ending in a pair of erect submesal points. Tenth tergite composed of an almost

triangular basal section; apical section directed

posteroventrally, apicolateral angle rounded, with

a pointed apicodorsal process and a small pointed

apicomesal tooth. Aedeagus with typical basal and

midventral processes; with lateral appendages

arising from a membranous base, apical spine long

and twisted; central tube scoop shaped apically, in

dorsal aspect with lateral points subapically, and

narrowly prolonged midventrally, with a small

central tubule.

Protoptila curiosa, new species

FIGURES 79-80

This extremely distinctive species seems at first

sight to be unrelated to any other known species

of the genus. Upon further analysis, however, it

seems to be a rather aberrant member of the dubitans complex. It is immediately recognized by the

shape of the ventrolateral lobe of the tenth tergum,

which in P. curiosa is divided into a long dorsal

arm and a thin, flat ventromesal plate.

ADULT.—Length of forewing 2.5-3 mm. Color in

alcohol brown, an indication of a transverse pale

band at anastomosis. Fifth sternum with an impressed line along posterior margin, ending in a

rounded flap laterally. Sixth sternum with a compressed midventral point. Male genitalia: Eighth

sternum broadly produced posteriorly, apex broadly and shallowly emarginate; eighth tergum produced posterolaterally as a rounded shoulderlike

lobe. Ninth sternum not produced; tergum sclerotized and complex, consisting of dorsolateral lobes

concave ventrolaterally. Tenth tergum borne from

venter of ninth tergum, with dorsomesal section

developed into a small point posteriorly; ventrolateral section strongly sclerotized, consisting of a

long, terete, posteriorly directed arm that is bowed

laterally, and a broad, flat plate directed posteroventrally. Aedeagal complex with usual basal lobes;

midlength complex, consisting of stout lateral and

ventromesal spines; with a long, slender lateral

spine arising from a membranous base; central

tube slender basally, slightly enlarged apically,

dorsoapical surface concave with a small central

spine.

Protoptila choluteca, new species

FIGURES 81-82

This species is closely related to Protoptila cardela Mosely. It differs most strikingly in that the

posteroventral process of the tenth tergite barely

reaches the apical lobe of aedeagus, whereas this

process clearly surpasses the lobe in P. cardela.

The apical margin of the ninth sternum in P.

choluteca is bifid, and developed into small points

rather than being a long, mesal, hooked process as

in P. cardela. There are also minor differences in

shape of most other sclerites in the two species.

ADULT.—Length of forewing 3 mm. Color brown

in alcohol. Sixth sternum with a pointed, com--

pressed mesal process. Male genitalia: Eighth sternum broadly produced posteriad, posterior margin

with a broadly V-shaped excision; tergum with

posterior margin straight, darkened, with a fringe

of bristles. Ninth sternum almost completely covered by eighth, posteroventrally produced into 2

upright spines, in ventral aspect these spines are

divaricate. Tenth tergite rectangular basally, with

posteroventral angle produced into a long process.

Aedeagus with a large, mesal basodorsal lobe, a

pair of ventral rodlike appendages; midlength

complex, consisting of a thin lateral lobe and a

pair of erect mesal spines; giving rise to lateral

processes appressed to central tube and ending

in a ventrally directed point; central tube thin,

ending in a curved central spine, and a ventral

membranous lobe, lined with many short setae.

Protoptila ignera, new species

FIGURE 78

This species is closely related to the Amazonian

Protoptila condylifera Flint. It differs primarily

in the shape of the tenth tergite, which in P. ignera

has a longer dorsal margin and a more ventrally

directed lobe, and in the apex of the aedeagus,

whose dorsal spines are strongly twisted and whose

central tube is greatly enlarged.

ADULT.—Length of forewing 3 mm. Color in

alcohol uniform brown. Sixth sternum with a short,

pointed, compressed apicomesal process. Male genitalia: Eighth sternum produced posteromesally,

with apex bifid. Ninth sternum produced and

slightly projecting above eighth sternum, tip in

ventral aspect slightly bilobate. Tenth tergite with

basal section elongate, roughly quadrate; apical

section with dorsal margin nearly straight, with

ventral lobe rounded apically and giving rise subapically to a small, mesally directed tooth. Aedeagus

with typical basal lobes, and midlength complex;

central tube small at base of tenth tergite, depressed and greatly expanded laterad just beyond

tenth tergite, and giving rise to a pair of dorsal

spines strongly convoluted basally, apex of central

tube greatly enlarged, with a central spine.

Protoptila chontala, new species

FIGURE 83

This very distinctive new species appears to be

most closely related to the Brazilian P. condylifera

Flint. It differs rather strikingly, however, in the

shape of the eighth sternum, which in P. condylifera

is a long, slender mesal process divided apically.

There are also smaller differences in all other parts

of the genitalia.

ADULT.—Length of forewing 3.5 mm. Color unknown; cleared and in alcohol. Sixth sternum with

a compressed apicomesal process. Male genitalia:

Eighth sternum with a long, pointed posterolateral

process, and a smaller, pointed ventrolateral lobe,

posteromesally with deep, almost circular excision.

Ninth sternum elongate, posterior margin broad,

with a broadly V-shaped mesal emargination.

Tenth tergite with an elongate, rectanguloid basal

section; apical section decumbent, with a small,

rounded ventrolateral lobe, and a small, pointed

mesal lobe. Aedeagus with usual basal and mesal

lobes and processes; central tube slightly angulate,

bearing dorsally a pair of long, slender processes;

apex membranous with a central spine.

Protoptila mixteca mixteca, new species

and new subspecies

FIGURE 85

This species seems to be somewhat distantly related to P. huasteca Flint, but is immediately recognized by the very different shape of the eighth

sternum and aedeagus.

ADULT.—Length of forewing 3 mm. Color in

alcohol pale brown; completely denuded. Sixth

sternum with a pointed apicomesal process. Male

genitalia: Eighth sternum with posteromesal margin produced into a fingerlike lobe. Ninth sternum

produced within eighth sternum as a narrow lobe,

with a mesal, ventral keel. Tenth tergite with

posterodorsal angle of basal section considerably

enlarged; apical section pendulous, ending in a

small point, and with a small mesal point. Aedeagus

with usual basal lobes, with a pair of midventral

flared lobes; central tube giving rise apically to

a pair of projecting dorsolateral spines, a pair of

ventrolateral winglike lobes, and a mesoventral

hook.

Protoptila mixteca veracruzensis, new subspecies

FIGURE 86

This and the nominate subspecies are extremely

similar, differing only in comparative aspects of

the tenth tergite, aedeagus, and ninth sternum.

The dorsomesal process from the base of the

aedeagus in P. m. mixteca is expanded dorsally

at both the anterior and posterior angles, whereas

in P. m. veracruzensis the keel is broader and the

posterior margin is concave below the apex. The

shape of the tenth tergite is, however, the most

distinctive characteristic. In P. m. veracruzensis

the apical point is drawn out posteriad into an

elongate, sinuous process.

Manuscripts for serial publications are accepted by the Smithsonian Institution Press, subject to substantive review, only through departments of the various Smithsonian museums. NonSmithsonian authors should address inquiries to the appropriate department. If submission is

invited, the following format requirements of the Press will govern the preparation of copy.

Copy must be typewritten, double-spaced, on one side of standard white bond paper, with

W'2," top and left margins, submitted in ribbon copy with a carbon or duplicate, and accompanied by the original artwork. Duplicate copies of all material, including illustrations, should be

retained by the author. There may be several paragraphs to a page, but each page should begin

with a new paragraph. Number consecutively all pages, including title page, abstract, text, literature cited, legends, and tables. The minimum length is 30 pages, including typescript and illustrations.

The title should be complete and clear for easy indexing by abstracting services. Taxonomic

titles will carry a final line indicating the higher categories to which the taxon is referable:

"(Hymenoptera: Sphecidae)." Include an abstract as an introductory part of the text. Identify

the author on the first page of text with an unnumbered footnote that includes his professional

mailing address. A table of contents is optional. An index, if required, may be supplied by the

author when he returns page proof.

Two headings are used: (1) text heads (boldface in print) for major sections and chapters and (2) paragraph sideheads (caps and small caps in print) for subdivisions. Further

headings may be worked out with the editor.

In taxonomic keys, number only the first item of each couplet; if there is only one couplet,

omit the number. For easy reference, number also the taxa and their corresponding headings

throughout the text; do not incorporate page references in the key.

In synonymy, use the short form (taxon, author, date:page) with a full reference at the

end of the paper under "Literature Cited." Begin each taxon at the left margin with subsequent lines indented about three spaces. Within an entry, use a period-dash (.—) to separate

each reference. Enclose with square brackets any annotation in, or at the end of, the entry.

For references within the text, use the author-date system: "(Jones, 1910)" and "Jones

(1910)." If the reference is expanded, abbreviate the data: "Jones (1910:122, pi. 20: fig. 1)."

Simple tabulations in the text (e.g., columns of data) may carry headings or not, but they

should not contain rules. Formal tables must be submitted as pages separate from the text, and

each table, no matter how large, should be pasted up as a single sheet of copy.

Use the metric system instead of, or in addition to, the English system.

Illustrations (line drawings, maps, photographs, shaded drawings) can be intermixed

throughout the printed text. They will be termed Figures and should be numbered consecutively; however, if a group of figures is treated as a single figure, the components should be

indicated by lowercase italic letters on the illustration, in the legend, and in text references:

"Figure 9b." If illustrations (usually tone photographs) are printed separately from the text as

full pages on a different stock of paper, they will be termed Plates, and individual components

should be lettered (Plate 9b) but may be numbered (Plate 9: figure 2). Never combine the

numbering system of text illustrations with that of plate illustrations. Submit all legends on

pages separate from the text and not attached to the artwork. An instruction booklet for the

preparation of illustrations is available from the Press on request.

In the bibliography (usually called "Literature Cited"), spell out book, journal, and

article titles, using initial caps with all words except minor terms such as "and, of, the." For

capitalization of titles in foreign languages, follow the national practice of each language.

Underscore (for italics) book and journal titles. Use the colon-parentheses system for volume,

number, and page citations: "10(2) :5-9." Spell out such words as "figures," "plates," "pages."

For free copies of his own paper, a Smithsonian author should indicate his requirements

on "Form 36" (submitted to the Press with the manuscript). A non-Smithsonian author will

receive 50 free copies; order forms for quantities above this amount with instructions for payment will be supplied when page proof is forwarded.
