Published: January 2010

The Dolichopod herewith described belongs to a genus containing a large number of species having very similar form. The new form is related to tristis Loew but is readily distinguished by the wholly black legs.
THE APPLE CURCULIO AS A PEAR PEST IN BRITISH COLUMBIA
Authors: Buckell E. R.
Published: January 2010

During the early summer months of 1927, 1928 and 1929, several fruit growers in the Salmon Arm district of British Columbia noticed severe injury to the small developing fruits of their pear trees. By the end of June as high as 80 per cent. of the small pears had fallen from some of the trees, and the majority of those remaining were deformed and unmarketable at harvesting time.
OBSERVATIONS ON THE BEHAVIOR OF BUMBLEBEES (BREMUS): THE ORIENTATION FLIGHT
Authors: Frison T. H.
Published: January 2010

The manner in which bees and wasps repeatedly find their way back to their nests or to certain other places has been a source of wonderment to many and the subject of serious investigations upon the part of but few. The justly illustrious Fabre in considering the homing of many insects was led to believe that wasps and bees found they way back and forth from the nest by a special sense.
THE EPHEMEROPTERA OF THE NORTH SHORE OF THE GULF OF ST. LAWRENCE
Authors: McDunnough J.
Published: January 2010

A very interesting collection of Ephemeroptera was brought back to Ottawa by Mr. W. J. Brown who spent the entire summer of 1929 on an insect faunal survey along the north shore of the Gulf of St. Lawrence, the survey extending from Trinity Bay in the west, where the fauna is still typically Canadian and Hudsonian, to Bradore Bay at the entrance to the Straits of Belle Isle, where the conditions are very similar to those found on the Labrador coast.
MORTALITY OF POLISTES ANNULARIS WASPS DURING HIBERNATION
Authors: Rau Phil
Published: January 2010

In “Wasp Studies Afield” we recorded the enormous mortality of these hibernating queens in the crevices of rocky bluffs. Since that record was made, on half a dozen different occasions, I have found handfuls of dead wasps on the window-sills of several club-houses.
VESPULA INTERMEDIA (BUYSS.) IN MANITOBA
Authors: Neave Ferris
Published: January 2010

In his “Monographie des Guêpes,” published in 1904-05, R. du Buysson describes a new form under the name of Vespa rufa, var. intermedia. His description was based on material in the Paris and British Museums and the localities given are Lake Hanka in Manchuria and Hudson's Bay. I am not aware of any subsequent records in North America.
NEW SPECIES OF COLEOPTERA I
Authors: Brown W. J.
Published: January 2010

Length 3.6-4 mm.; width 1.7-1.9 mm. Elongate oval, subequally narrowed in front and behind. Dorsum very dark brown, the anterior portion of the head pale brown, a median band extending across the pronotum sometimes slightly paler, elytra near basal and lateral margins sometimes very slightly paler; antennae reddish-yellow, the segments except the basal four each strongly infuscate except at base; legs and prothoracic venter reddish-yellow; remainder of venter black, shining.
PHENACOCCUS WILMATTAE CKLL
Authors: Bueker Elmer D.
Published: January 2010

On May 23, 1929 a species of Phenacoccus was found in ant's nests of the genus Lasius. Some of these were feeding on the roots of grass and were well guarded by the ants. Mature males were also found in the nest. After going carefully through the literature I find that it agrees well with the description of P. wilmattae Ckll. However, since a number of very obvious characters were omitted in the original description it will be profitable to mention them, and emphasize the outstanding differences between this species and P. stachyos Ehrhorn.
BIOLOGIC NOTES ON MICRORHOPALA VITTATA FABR. (COLEOPTERA: CHRYSOMELIDAE)
Authors: Hendrickson George O.
Published: January 2010

Late in the summer of 1926, several adults of the beetle (Microrhopala vittata Fabr.) were found in the blistered portions of leaves of the compass plant (Silphium laciniatum L.). The insect is black with head and thorax red and with red stripes on the second costa and at the outer margin of each elytron. It is subdepressed and about 6 mm. long.
A REVIEW OE THE GENUS PALMACORIXA ABBOTT (HEMIP., CORIXIDAE)
Authors: Walley G. Stuart
Published: January 2010

The genus Polmacorixa was erected by Abbott (Ent. News, XXIII, 337, 1912) for a single species, Palmacorixa gillettii Abb. described from three males and three females collected at Fort Collins, Colorado, during May and June, by Professor C. P. Gillette. Subsequently (Can. Ent., XLV, 113, 1913) Dr. Abbott described a second species, Palmacorixa buenoi Abb. from specimens taken at White Plains, New York, during August and September, by Mr. J. R. de la Torre-Bueno. A third species, Palmacorixa mexicana Hungfd. has been described by Dr. H. B. Hungerford (Pan-Pac. Ent., IV, 94, 1927) from a pair of specimens collected in the Xochimilco Sea, Mexico, by Dr. A. Dampf.
NEW SPECIES OF COLEOPTERA (II)

Length 8.4-9.3 mm.; width 4.3-4.8 mm. Moderately elongate, oval. Black; dorsum feebly shining and with a very feeble aeneous tint; two spots on the vertex, the anterior part of the head, and sides of elytra usually brown or brownish-yellow; antennae yellow, with four or five apical segments brown; palpi yellow, the apical segment of each brown; prosternum and legs dark brown.
NOTES ON CHRYSOPA OCULATA SAY AND ITS RELATION TO THE ORIENTAL PEACH MOTH (LASPEYRESIA MOLESTA BUSCK.) INFESTATION IN 1930
Authors: Briand L. J.
Published: January 2010

While making peach twig collections for parasite recoveries during the first part of June, a few Chrysopid adults were observed throughout the orchards. No particular attention was paid to this insect until late in July, when adults could be found on almost every tree throughout the orchards of the Niagara district. Several specimens were sent to Ottawa for determination and it was found that two species were represented, viz., Chrysopa oculata Say. and Chrysopa albicornis Fitch., the former being by far the more numerous. Eggs began to appear the latter part of July and could be located in numbers varying from one to four on almost every tree.
THE BIOLOGY OF CANADIAN BARK-BEETLES: THE SEASONAL HISTORY OF DENDROCTONUS RUFIPENNIS KY. IN NORTHERN ONTARIO
Authors: Watson E. B.
Published: January 2010

This bark-beetle is locally distributed over the forested areas of Quebec and Ontario, extending westward into Manitoba; in the United States, it has been recorded from Wisconsin and Michigan.

The insect has been found breeding in fallen white pine and jack pine, and, within recent years, has also been recorded from red pine.
SOME ERYTHRONEURA (GRAPE LEAF HOPPERS) OF THE MACULATA GROUP. (HOMOPTERA, CICADELLIDAE)
Authors: Beamer R. H.
Published: January 2010

The genus Erythroneura was divided by W. L.. McAtee and later confirmed by Wm. Robinson, into several groups by the venation of the front wing. The maculata group was characterized particularly by the absence of the M-Cu cross-vein and by the base of cell M4 being angulate. In dissecting and studying the male genitalia of several hundred specimens of this group a good many undescribed forms have been found. It is the purpose of the present paper to begin a study of the entire group, redescribing named species wliere necessary and adding the new forms. Drawings and photographs have been made but will be published later.
A NEW SPECIES OF MYOCHROUS (CHRYSOMELIDAE, COLEOP.)

A NEW ARGYROPLOCE SPECIES (EUCOSMIDAE, LEPID.)
Authors: McDunnough J.
Published: January 2010

Some time ago, through the kindness of Mr. Tams of the British Museum, I was enabled to have specimens compared with the types of dealbana Wlk. and similisana Wlk. and the genitalia of both types examined. The result is a confirmation of Heinrich's placement in his revisioni, dealbana falling to glaciana Moesch. and similisana to bipartitana Clem.
NOTES ON UTAH DIPTERA

Published: January 2010

The fauna of Utah is unusually rich in Diptera. Much remains to be done by way of recording the forms that occur in this area and in learning the distribution of the economic forms within the state. The following records are from recently classified material of the Utah Agricultural Experiment Station collection. The writer is indebted to Messrs. J.M. Aldrich, C.H. Curran, C.T. Greene, R.H. Painter, and J.S. Hined for naming most of the material listed below.
STUDIES IN THE MELYRIDAE, NO. 9. (COLEOPTERA.)
Authors: Blaisdell Frank E.
Published: January 2010

Two of the species described below were discovered very recently and constitute a very interesting addition to our Melyrid fauna. The individuals or units of a species vary more or less and this variation makes the work of the taxonomist rather uncertain and difficult as regards the characterization of a species, until considerable series has been studied from some single locality. When a knowledge of the range and degree of variation has once been obtained, the systematist can proceed with greater confidence as regards the status of the species he describes. Collectors should bear in mind the need of series for the study of variation.
A NEW BEE OF THE GENUS ANDRENA FROM CANADA
Authors: Cockerell T. D. A.
Published: January 2010

Professor W.H. Brittain has sent me a small lot of Andrena collected this year, and among them I find a species so striking that it should be described at once. As I am leaving for Africa it will be impossible to deal with the rest of the collection at this time.
SOME NEW NORTH AMERICAN GENERA AND SPECIES IN THE GROUP FORMERLY CALLED PLATYMETOPIUS (RHYNCHOTA, HOMOPTERA)
Authors: Ball E. D.
Published: January 2010

The writer has been working on the food plants of the leaf-hoppers for many years and has found in the main the different species of the genus Platymetopius, as commonly recognized, are very closely confined to a single species of plant or to a closely related group. Before it was possible to prepare a list of the food plants in the group it was found necessary to describe a number of new species of which food plant and life history information was available. In working out the relationship of these species, two startling discoveries were made.
III. NEW COLEOPTERA FROM WESTERN CANADA
Authors: Hopping Ralph
Published: January 2010

During the last few years' collecting in British Columbia, certain new species of Coleoptera have accumulated, until the writer now has a sufficient series of each to warrant their description.
ON COLOR DIMORPHISM IN PODALONIA VIOLACEIPENNIS (LEP.). (HYM.:SPHECINI)
Authors: Fernald H. T.
Published: January 2010

In a paper on “The Digger Wasps of the Genus Podalonia (Psammophila)” (Proc. U. S. Nat. Mus., Vol. 71, p. 25, 1927) the writer ended a discussion of the possibility that Podalonia luctuosa Sm. is only a differently colored P. violaceipennis (Lep.) with the statement : “On the whole it seems best to leave luctuosa as a species separate from violaceipennis, for the present, until more pairs have been captured and the evidence they may give becomes available.”
A SYNOPTIC REVISION OF THE GENERIC CLASSIFICATION OF THE CHELONETHID FAMILY CHELIFERIDAE SIMON. (ARACHNIDA)
Authors: Chamberlin Joseph Conrad
Published: January 2010

The following synoptic revision of the family Cheliferidae is presented at this time in order to render available for routine systematic use the expanded classification of this important family necessitated by recent morphological and systematic research. It follows along the lines already laid down by the author in previous papers on the higher classification of the Chelonethida as a whole (Chamberlin, 1939, 1930 and 1931) and differs only in the fact that consideration of included species is omitted in all but a few special cases.
REVISION OF THE NORTH AMERICAN AEGIALIINAE (COLEOPTERA)
Authors: Brown W. J.
Published: January 2010

Length 3.6 - 4.3 mm.; width 1.8 - 2.2. mm. Body moderately convex. Brown or blackish, the legs and sometimes the venter paler ; shining.

Front rather coarsely, closely punctate, clypeus granulate, the granules fine and moderately close.
OBSERVATIONS ON SOME AQUATIC ANIMAL AND PLANT ENEMIES OF MOSQUITOES
Authors: Twinn C. R.
Published: January 2010

Animal and plant enemies undoubtedly play an important part in controlling mosquitoes, but it is fully recognized that a study of these organisms forms only one phase of a very complex subject spoken of generally as natural control. Climate, weather conditions, topography, etc., all have an important bearing on mosquito abundance. Precipitation, whether in the form of rain or snow, and temperatures, exert a vital influence on mosquito populations. If the winter accumulation of snow is heavy, the spring infestation of snow pool and floodwater mosquitoes may be expected to be heavy too.
A NEW RACE OF SPHINX GORDIUS (LEPID.)
Authors: McDunnough J.
Published: January 2010

Differs from typical gordius from the cast in its smaller size and more constrasted maculation, the costa and inner margin of forewing being shaded with deep smoky whilst the central portion of the wing is suffused with whitish shades, especially preceding the wavy subterminal dark line. Between this line and the outer margin of the wing the teriminal area is heavily suffused with deep smoky, in contradistinction to gordius borealis Clark in which this region is sprinkled with whitish, more as in the typical form. The dark intravenular streaks are reduced, much as in gordius oslari R. & J. from Colorado, but from this race the smaller size and the better defined transverse lines will distinguish it. Expanse 70 mm.
PARASITES REARED FROM FOREST INSECTS IN 1929
Authors: Schedl Karl E.
Published: January 2010

Very common in the orchards of the Central Experimental Farm at Ottawa, Ont. Branches of many varieties of apple trees were found infested throughout the summer. In the tunnels frequently were observed specimens of Salpingus virescens Lec. (det. W. J. Brown).
MALLOPHAGA FROM UTAH BIRDS AND MAMMALS
Authors: Stanford J. S.
Published: January 2010

The Mallophaga listed were collected from birds and mammals taken principally by the writer in various parts of Utah as indicated. The numbers found on the infested hosts varied from one or more to scores. The shore birds and jay were most heavily infested. The lice almost invariably came to the surface of the feathers or fur when the hosts became cold.
THE BIOLOGY OF THREE NORTH AMERICAN SPECIES OF MESOVELIA (HEMIPTERA-MESOVELIIDAE)
Authors: Hoffmann Clarence H.
Published: January 2010

Egg.—The egg is described by Hungerford (11) as being “elongate-oval, with a curved neck terminating in a flat surface which marks the exposed end of the egg as it lies in situ in the stem of some plant”. It is white when first laid, but within a few days it becomes watery transparent as the embryo begins to take form. The deep red eye spots and segmentation appear two days before hatching. Measurements of ten eggs of this species show the average length to be .877 mm., the greatest diameter .268 mm., and the diameter of the exposed end of the egg to be .163 mm.

General ground color yellowish white to semihyaline, markings red or orange. Vertex with semblance of three white spots more or less surrounded with red or orange bands. Pronotum with rather short triangular median spot, not touching either margin. Usual angular spot back of each eye. Scutellum with tip red, basal angles yellow outlined on two sides with red. Clavi with usual basal anchor-shaped mark and angular mark before tip. Coria with spot on costa midway between costal plaque and humeral angle, angulate vitta at anterior end of plaque, rectangular spot opposite middle of plaque, two spots at posterior end and blotch before base of cell M4. Cross-veins red. Black spot in base of cell M4. Tips of tegmen more or less dusky. Venter stramineous more or less tinged with pink.
NOTES ON SPHEX ABERTI (HALD.)
Authors: Hicks Charles H.
Published: January 2010

Dr. H. T. Fernald (4) gives as synonyms of Sphex aberti (Hald) the names Ammophila yarrowi Cress. and A. moontezuma Cam. This species was one of the first of our wasps to which has been ascribed the rernarkable habit of using a pebble or other suitable object as a tool. The observation was made by Dr. S. W. Williston (9) in 1892 on specimens determined as A. yarrowi. He considered the habit so unusual that he refrained publication for a time thinking the act might be doubted. It is now an accepted fact, though somewhat variously interpreted, and has been witnessed by a number of careful and accurate observers in this and other species.
A EUROPEAN SAWFLY (DIPRION POLYTOMUM (HARTIG) ATTACKING SPRUCE IN THE GASPE PENINSULA, QUE.
Authors: Balch R. E. , Simpson L. J.
Published: January 2010

In November, 1930, spruce stands throughout a great deal of the interior of the Gaspe peninsula were found to have been partially defoliated by a sawfly. In some areas the greater part of the foliage had been eaten; about ten cocoons per square foot were found in moss and litter on the ground, beneath the trees.
A NEW SPECIES OF FORCIPOMYIA (DIPT.; CHIRONOMIDAE)
Authors: Walley G. Stuart
Published: January 2010

Male.—Length 2 mm. Black, shining. Antennal plumes black; basal antennal segment dull black, segments of flagellum brownish.

Thorax black, pleural membranes brownish, dorsum greyish pollinose; scutellum and metanotum dull black with faint pollen. Halteres dark brownish with creamy white knobs.
NOTES ON THE EARLY STAGES OF THE EUROPEAN PINE SHOOT MOTH
Authors: Degryse J. J.
Published: January 2010

When the European pine shoot moth was first found in North America in 1914, considerable interest was aroused by the discovery and no less fear regarding the potentiality of the insect as a menace to native forests and pine plantations. As the years went by and the pest appeared to be confined mostly to nursery stock and ornamentals, much of the original interest waned only to be rather suddenly revived by recent reports of widespread damage to certain pine plantations both in Canada and the United States.
A SYNOPTIC REVISION OF THE GENERIC CLASSIFICATION OF THE CHELONETHID FAMILY CHELIFERIDAE SIMON. (ARACHNIDA)

Cheliferini tribus nov.

Diagnosis. Male: coxal sac entire, lacking a sharply differentiated atrium; statumen convolutum of male genitalia (with a few doubtful and rare exceptions) anteriorly deeply invaginated or retracted and bearing medianally in the depression an anteriorly projecting sclerotic “rod” (see Chamberlin, 1931). Female: median pair cribriform plates separate and distinct.

SOME ERYTHRONEURA (GRAPE LEAF HOPPERS) OF THE MACULATA GROUP (HOMOPTERA, CICADELLIDAE)
Authors: Beamer R. H.
Published: January 2010

An effort has been made in the preceding pages to present all the species of Erythroneura that have been described in the Maculata Group as well as a large number of new species. The scutelleris Group is included also because it was found they could not easily be separated on the external characters as given by other writers and the genitalia showed close relation to the Maculata Group. No doubt other species will be found as more intensive collecting is done in various parts of the country.
HOST RECORDS AND NEW SPECIES OF CANADIAN HYMENOPTERA
Authors: Walley G. Stuart
Published: January 2010

The following notes are based on material in the Canadian National Collection at Ottawa. A large proportion of the reared material was obtained by Dr. J. McDunnough at Bobcaygeon, Ont. in the course of his studies on the Lepidoptera of that region. His rearings of several species of Haploptilia yielded a number of parasites the habits of which have heretofore been little known in Canada. Other material mentioned below was reared by the writer and by various economic officers of the Entomological Branch staff. The determinations of the lepidopterous hosts of the Bobcaygeon material are by Dr. McDunnough.
NESTING HABITS OF SPHEX XANTHOPTERUS (CAM.) (HYMEN.)
Authors: Hicks Charles H.
Published: January 2010

Certain of the nesting habits of the wasp, Sphex xanthopterus (Cam.), have been observed at and near Los Angeles, California. The insect nests for the most part in the moist or wet, sandy soil of the river bed. It digs a short tunnel and enlarges it into a cell at the end. Into this is stored a stung lepidopterous larva, often the young of the moth, Zale lunata (Drury) and its varieties, to the side of which is fastened the egg of the wasp. The entrance to the tunnel and nest is then closed and in due time, if all goes well the egg hatches, the larva devours the prey, spins its cocoon, pupates, and later emerges an adult wasp. A more detailed account of some of the facts in its nesting habits and life history is given below.
ADDITIONAL NOTES ON THE COLEOPTERA OF THE NORTH SHORE OF THE GULF OF THE ST. LAWRENCE
Authors: Brown W. J.
Published: January 2010

During the summer of 1930, I returned to the north shore of the Gulf of the St. Lawrence and spent three months collecting there. Most of the collecting was done at Thunder River, a village on the mainland opposite the western end of Anticosti Island, and at Bradore Bay, situated at the western extremity of the Straits of Belle Isle.
NEW SPECIES OF NORTH AMERICAN EPHEMEROPTERA II
Authors: McDunnough J.
Published: January 2010

Male. Very similar in all respects to guttata McD. but noticeably larger in size. Thorax deep blackish, tinged with brown in the pleural sutures. Abdomen with segments 2-6 and anterior portion of 7 whitish, hyaline, with considerable brownish shading on 2. In place of the lateral black dots of guttata there is a short black transverse streak in the postero-lateral corner of segments 2-6 with some slight brown suffusion anterior to it, especially on segment 2. Rear segments deep chocolate-brown.

Mesonotum tricarinate, median carina well defined anteriorly but obsolescent at apex, lateral carinae entire, distinctly divergent posteriorly.
THE GEOGRAPHICAL RACE-CONCEPT IN LEPIDOPTERA
Authors: Garth John S.
Published: January 2010

In recent years there has been a growing tendency on the part of several eastern writers to place in synonymy races of our North American butterflies from widely separated localities. The attempt at simplifying our crowded check list is to be commended, but we do not see the advantage gained where such simplification is at the expense of the geographical race-concept.
NOTES ON SOME GALERUCINAE WITH DESCRIPTIONS OF NEW SPECIES (COL., CHRYSOMELIDAE)
Authors: Schaeffer Chas.
Published: January 2010

Dr. Horn in his revision of the Galerucini places erosa, morosa and maritima as plain synonyms with puncticollis with the remark that no tangible difference seems to exist. In this he is wrong for on comparing typical puncticollis from Colorado, N. Dakota, etc. with maritima from the Atlantic coast the differences are very obvious. The latter have the prothorax much less roughly sculptured, more smooth, the elytral punctures are larger and more densely placed and the elytral pubescence generally scarcely visible, at least more easily abraded than in the typical form.
THE FOOD PLANTS OF THE LEAFHOPPERS FORMERLY INCLUDED IN THE GENUS PLATYMETOPIUS BURM
Authors: Ball E. D.
Published: January 2010

Most writers in discussing the food plants of leafhoppers in the past have assumed that the majority of them were grass feeders. In the last few years a considerable amount of careful work has been done with the result that it is now evident that in a number of important groups the food plants are rarely if ever grasses.
THREE NEW AMERICAN MAYFLIES (EPHEMEROP.)

Two of my colleagues, in years long gone by, have brought back to me from their journeyings specimens of interesting undescribed mayflies that I have placed in the Cornell University collection to arvait for study a more convenient season. Three of these I now describe. The first two are rather unique species of two well-known genera.
A NEW CANADIAN ANDRENA (HYMENOPTERA, APOIDEA)
Authors: Cockerell T. D. A.
Published: January 2010

Recently having occasion to study a group of metallic-colored Andrena, I took up a couple of paratypes of A. sladeni Viereck in my collection, and discovered that they belonged to quite different species. From Viereck's original description, I could not definitely make out which was the genuine A. sladeni, nor, indeed, whether that name really belonged to either of them.
NEW SPECIES OF COLEOPTERA III

The species described below are from sereral lots of beetles submitted to the author during recent months. Several of the species are of unusual interest, especially the Phytobius and the Trichocellus. The latter represents a subgentls new to North America and was included in a fine lot of arctic beetles collected by Mr. A. E. Porsild. The collections made in British Columbia by Mr. G. Stace Smith continue to add materially to our knowledge of the beetles of the province.
SOME UNDESCRIBED RACES OF NOTODONTIDAE (LEPID.)

FURTHER NOTES ON THE EPHEMEROPTERA OF THE NORTH SHORE OF THE GULF OF ST. LAWRENCE
Authors: McDunnough J.
Published: January 2010

In the “Canadian Entomologist” for March, 1930 (pp. 54-62) I commented on the Ephenteroptera collected in 1929 by W. J. Brown at various points along the north shore of the Gulf of St. Lawrence. Further studies by Mr. Brown in 1930 at Thunder River (June 12-28 and Aug. 15-29) and at Bradore Bay (July 4-16 and July 29-Aug. 12) have resulted in a number of additional records which I present in the following paper.

THE BIOLOGY OF THREE NORTH AMERICAN SPECIES OF MESOVELIA (HEMIPTERA-MESOVELIIDAE).,
Authors: Hoffmann Clarence H.
Published: January 2010

The purpose of this paper is to present what is known at the present time concerning the life histories and habits of the Mesoveliidae, particularly those of three species of the genus Mesovelia Muls. found in North America. Studies on our most common species, Mesovelia mulsanti bisignata Uhler, were carried out in Michigan and Kansas, while biological notes on the other two species were taken in the region of Douglas Lake, Michigan, their only known habitat. Isolated rearings and life history studies of all three species were made at Lawrence, Kansas.
NOTES ON PSEUDOLUCANUS PLACIDUS (SAY). (LUCANIDAE, COLEOPTERA)
Authors: Milne Lorus J.
Published: January 2010

The literature concerning the large Stag-beetle Pseudolucanus placidus (Say) contains many conflicting and misleading data. Since the species occurs in exceptional abundance in a very restricted sandy area surrounding the author's home, it became a fairly easy task to check up on these statements. Thc present paper contains the information gathered during the past several years.
FOOD PLANTS AND DISTRIBUTION OF SOME UTAH THYSANOPTERA
Authors: Knowlton G. F. , Thomas W. L.
Published: January 2010

Thrips have frequently been abundant in flowers and less abundant upon other parts of plants in most sections of Utah. Considerable thrips damage to onions occurs practically every year in most onion-growing areas of this state, while beans, beets, and other crop plants are less generally affected. It appears that damage, due to thrips, is more general in Utah than has usually been supposed. A desire to become better acquainted with the forms occurring upon various plant species in this region has led to this study.
FOOD OF THE ROBBER FLY, MALLOPHORA ORCINA (WIED) (DIPTERA)
Authors: Fattig P. W.
Published: January 2010

For several years I have been interested in the prey of the Robber Fly, Mallophora orcina (Weid). I have taken two hundred and eighteen specimens of this robber fly with its prey. The prey belonged to twenty-three species of insects.

It will be noticed that not a single specimen was taken with the large yellow jacket (Vespa carolina), although this species is as common here as is the smaller yellow jacket (Vespa germanica). Ten specimens were taken with Liacos nobilitata, while not a single specimen was taken with Liacos bicincta, although it is as common here as is nobilitata.
STUDIES IN THE ELATERIDAE, I (COLEOP.)
Authors: Brown W. J.
Published: January 2010

The North American species of this difficult genus are very poorly
known. The names of our species, as listed in Leng's catalog, are in need of
some revision. One name, mellillus (Say), has
escaped the attention of all authors but is valid for the common
Drasterius elegans of our
literature.
LEMA TRILINEATA OLIV. IN MANITOBA (COLEOPTERA, CHRYSOMELIDAE)
Authors: Criddle Norman , Handford R. H.
Published: January 2010

The difference in food plants and seasonal life-history between beetles of the species Lema trilineata Oliv. in Manitoba and the same species in Eastern Canada and Eastern United States indicates rather strongly that they belong to different biological races. The belief was entertained for a time that the Manitoba beetle belonged to an entirely different species, but a series of adults sent to Mr. W. J. Brown of the Dominion Entomological Branch, Ottawa, proved to be identical with the eastern species.
A NEW SPECIES OF THRIPSAPHIS FROM ILLINOIS (APHIIDAE, HOMOPTERA)
Authors: Frison T. H. , Ross H. H.
Published: January 2010

During the course of recent collecting in Illinois, an interesting species of aphid has been discovered on sedges (Carex sp.). It differs so radically, however from all species hitherto described in that genus that a new subgenus has been proposed for its reception. In view of the recent publication on the “Aphiidae of Illinois” and the very interesting character of the species it seems advisable to describe it at this time.
BIOLOGICAL NOTES ON SOME OF OUR EASTERN ONTARIO HAPLOPTILIA SPECIES (LEPID.) WITH DESCRIPTIONS OF TWO NEW SPECIES
Authors: McDunnough J.
Published: January 2010

During field work at Bobcaygeon, Ont., in the summers of 1931 and 1932 I paid particular attention to the collecting and breeding of Haploptilia larvae and was successful in securing considerably over a dozen species. As very little has been published on this interesting group apart from Heinrich's excellent treatment in Forbes' Lepidoptera of New York State (1924, Mem. 68, Cornell Univ. Agr. Exp. Sta. pp. 202-217) it has occurred to me that the publication of my field notes, combined with a photographic figure of the characteristic larval case pertaining to each species, might be of value to students.

A NEW MEXICAN COPRIS (SCARAB., COLEOP.)
Authors: Saylor Lawrence W.
Published: January 2010

Holotype male. Piceous, shining, form of arizonensis but slightly smaller. Clypeus narrowly emarginate and notched at centre of apex, head in front and on sides coarsely punctate; smooth behind, genae acute, prominent, coarsely and rather densely punctate; frontal horn long, arcuate, surface deeply pitted on sides and rear, front smooth. Thorax with a median protuberance triangularly emarginate at apex, the angles rounded and convergently apically; surface of protuberance slightly flattened, with distinct longitudinal impression, very coarsely and rather sparsely punctured at the centre; at each side near side margin a horn-like projection, the surface between these and the median protuberance deeply excavated and coarsely but rather sparsely punctate; between the usual short carina near the side margin and the horn-like projection is at about the middle a shallow fovea which is very coarsely punctured, surface of thorax coarsely punctate at margins, near front angles, and as noted above, the disc very finely and sparsely punctured; front angles obtusely subangulate, lateral margin near the front angles not sinuate, hind angles broadly rounded; fore part of thorax not tuberculate.
THE PARASITES OF PSEUDOCOCCUS COMSTOCKI KUW
Authors: Compere Harold
Published: January 2010

Pseudococcus comstocki Kuwana is classed among the injurious mealy-bugs. It attacks a wide range of host plants. So far it has become abundant in the United States only in certain states east of the Mississippi River. In Connecticut it has received the name catalpa mealybug, because of its injuriousness to that plant. It is recorded as attacking many food-producing plants, but so far it has not been rated as a serious pest of any commercial crop plants. P. comstocki has been recorded from California by G. F. Ferris, where it was taken on Monterey pines growing on the campus of Stanford University. Ferris also records this mealybug from a number of host plants, including citrus, collected in Japan by Dr. Kuwana. A lookout has been kept for the appearance of P. comstocki in southern California, as it is considered to be a potential pest of citrus.
THREE NEW SPECIES OF APHIDS FROM IDAHO
Authors: Miller Forrest W.
Published: January 2010

The species here described were collected by Walter R. Sweadner, Department of Zoology, University of Pittsburgh, during 1932. The writer is also indebted to Doctor E. H. Graham, Carnegie Museum, Pittsburgh, Pennsylvania, for the identification of the host plant material.
A NEW SPECIES OF MACROCENTRUS FROM NOVA SCOTIA (HYMENOP.)
Authors: Daniel Derrill M.
Published: January 2010

Female.—Length 7 mm. Head very little wider than thorax, cheeks, viewed from the side, broader than the temples; face much broader than long, shallowly sparsely punctate; eyes large, prominent; malar space about as long as basal width of mandible; clypeus convex, much less than twice as broad as long, the anterior margin truncate; distance from clypeal foveae to eyes about equal to length of clypeus; lateral ocelli not distinctly larger than median ocellus; longest segment of maxillary palpus distinctly shorter than second segment of antennal flagellum; apical segment of labial palpus much longer than preceding segment; antennae of the type broken, seven segments of flagellum present; first flagellar segment about as long as height of eyes.
A NEW SPECIES OF STAPHYLINUS (COL. STAPHYLINIDAE)
Authors: Cooper Kenneth W.
Published: January 2010

The species here described somewhat superficially resembles Staphylinus cinnamopterus Grav., yet appears distinct and to be hitherto uncharacterized. In admiration of Professor J. H. McGregor of Columbia University, and in appreciation of kindnesses tendered me, I propose to name this new form:

Staphylinus macgregori n. sp.

Habitus nearly as in cinnamopterus but larger in size and rather more robust; piceous, the elytra fusco-ferrugineus, the legs fulvo-ferrugineus ; pubescence inclined, on the head, thorax, and elytra of a rusty hue and with few erect, brown setae, on abdomen fusco-piceous pubescence intermixing with fewer rusty-colored hairs and an abundance of dark setae; anterior tarsi broadly dilated in both sexes ; head slightly narrower than prothorax, widest at basal fourth thence gradually narrowing anteriorly, hind angles obtusely prominent, punctures round and ocellate throughout, close-set but clearly separated by shining interspaces, sparser anteriorly; mandibles longer and more slender than in cinnamopterus, the two inner teeth much less prominent and more poorly developed; antennae piceous to fuscopiceous, a third longer than head; prothorax but slightly wider than head, truncate at apex, rounded at base, punctures ocellate, more elongate at the sides than those of head and somewhat larger, smaller and more closely set than in cinnamopterus but separated by shining interspaces, the median line evident, polished, but very narrow throughout, in places ill-defined or obliterated; scutellum velvety black; elytra fusco-ferrugineus, longer than wide, very finely but strongly and densely punctate, clothed with a decurved rusty-colored pubescence similar to that of head and thorax but more dense; abdomen obscurely fulvous at tip, piceous, coriaceo-reticulate and very sparsely and finely punctate at sides, with median velvety fuliginous spots suffering intermixture of short cinereous hairs at the sides; under surface of abdomen clothed with sparse, long, depressed, fuscs-piceous pubescence, coriaceo-reticulate, punctures very fine and sparse, slightly less sparsely distributed at sides of segments, the male fifth ventral with a very broad circular and feeble sinuation medially, the male sixth ventral obscurely fulvous at tip and with a broad, rounded, median emargination about one half as deep as long, fifth ventral of female truncate, sixth female ventral rounded evenly and fulvous. Length ( ) 10.0-12.7 mm.; width 3.0-3.3 mm.
SOME NEW DYTISCIDAE (COLEOPTERA)
Authors: Wallis J. B.
Published: January 2010

In the course of the preparation of a paper on the Dytiscidae of Minnesora and Manitoba several new species were discovered. As this paper, though finished, cannot be published for some time, it is felt wise to make these species known and the opportunity to add a few others is taken.
NEW COLEOPTERA FROM WESTERN CANADA IV
Authors: Hopping Ralph
Published: January 2010

Crotch, in his Check List of the Coleoptera, 1873, substitutes the name Pseudocistela Cr. for Cistela Fab. of the LeConte and Horn Classification. There seems to have been a doubt about Mulsant's genus Gonodera according to Leng, (Jour N. Y. Ent. Soc., XXVI, 209, 1918) who says “the genus Gonodera Muls. Col. Cr. Pectin, 1856, may cover our species and if so would antedate Crotch's name.” As we have not been able to see a specimen of the genus Gonodera, we are using the above name. Casey, (Annals N. Y. Acad. Sci., VI, 73, 1891), in his key, groups Pseudocistela with the genus Androchirus as having anterior tarsi “compressed and distorted” in the males. The genus Pseudocistela, however, does not (except brevis which has a slight distortion in the male) have the anterior tarsi compressed and distorted, but normal. Col. Casey's use of the word “distorted” instead of “deformed,” used by LeConte and Horn seems advisable.
NOTES ON THE HEPTAGENINE SPECIES DESCRIBED BY CLEMENS FROM THE GEORGIAN BAY REGION, ONT. (EPHEMEROP.)
Authors: McDunnough J.
Published: January 2010

Breeding at Go Home Bay confirmed what had already been suspected from our collections and breedings in the Ottawa and Knowlton regions, viz , that the nymph and female imago referred to by Clemens under the name flavescens belong to the species, ruber McD. Nymphs were secured at the Flat Rock Falls, the identical locality where they had been collected by Clemens, and two males, three females bred through to the adult stage (June 19, 21, July 2). The abdominal tergites of the nymph are not always as immaculately brown as indicated by Clemens ; there are frequently traces of pale dashes laterally and subdorsally along the anterior margins of the segments, serving to a certain extent to define the usual median and submedian dark bands and submedian dots.
NEW SPECIES OF COLEOPTERA IV
Authors: Brown W. J.
Published: January 2010

Male.—Length 12.4 mm. Body feebly convex. Dorsal surface of head, pronotum, and elytra green, not bronzed. Antennae, labrum, mandibles, palpi, scutellum, legs, and entire ventral surface including the elytral epipleura, black; vestiture bright reddish-brown.
A STUDY OF SPHEX BREVICEPS (SMITH) (HYMENOP.)
Authors: Hicks Charles H.
Published: January 2010

The digger wasp, S. breviceps, has been encountered frequently in the field while studying nesting bees and wasps. Ammophila pruinosa Cress., A. varipes Cress., and A. comanche Cam., according to Professor Fernald, must be considered as synonyms. It is a specics of considerable morphological variation with all intergrades occuring between the extremes. It is not a large insect but it makes up in numbers, it would seem, for what it lacks in individual size.
THE NYMPH OF CINYGMA INTEGRUM AND DESCRIPTION OF A NEW HEPTAGENINE GENUS
Authors: McDunnough J.
Published: January 2010

The species, integrum Eaton, described from material collected in Washington and Oregon states, was designated by Eaton as the genotype of Cinygma. I have already (1926, Can. Ent. LVIII, 302) recorded the capture of adults of this species in the Coast range of British Columbia and at the time expressed some doubt as to whether all the species at present included in this genus were strictly congeneric. Since nymphal structures have been recognized by a number of recent workers as of great importance in furnishing distinguishing characters in the Heptagenine genera it was with considerable interest that I discovered among material collected in the Hope Mts., B. C. in 1932 by my assistant, Mr. A. N. Gartrell, a bred female adult of integrum, together with its nymphal exuvia, preserved in alcohol. A study of this exuvia soon convinced me that in the nymphal gills and mouth-parts there are excellent and in part unique structural details which should at once establish not only the validity of the genus but also its limitations and position in the group of allied genera.
A NEW BOREUS FROM BRITISH COLUMBIA (MECOPTERA)
Authors: Carpenter F. M.
Published: January 2010

In a collection of Mecoptera belonging to the Canadian National Museum and sent to me for determination by Dr. McDunnough, I was much surprised to find several specimens of an undescribed species of Boreus. In as much as new species of North American Mecoptera are now rarely encountered and especially since this particular species is a most unusual one, I consider it justifiable to devote a separate paper to the description of this insect.
NOTE ON THE HIBERNATION OF PHYCIODES GORGONE, HBN. (LEPIDOPTERA, NYMPHALIDAE)
Authors: Handford R. H.
Published: January 2010

In the “Canadian Entomologist” for September, 1915, T. D. A. Cockerell writes of Phyciodes ismeria (gorgone Hbn.) that the “species evidently hibernates as a larva.” Observations in Manitoba have shown this deduction to be correct. A colony of larvae discovered on Helianthus scaberrimus Ell. (rigidus Desf.) in the Aweme district, July 20, 1928, hibernated in that stage, and one specimen successfully completed its development the following spring.
A NEW TRICHOCHROUS (COLEOPTERA-MALACHIDAE)
Authors: Fall H. C.
Published: January 2010

Of the usual elongate oblong form, about 2-2/3 times as long as wide, moderately convex; color black with faint greenish lustre, base of antennae, tarsi, and in the male the apex of the front tibiae dull rufous. Pubescence thin, not concealing the derm, consisting of sparse subrecumbent fulvocinereous hairs abundantly intermixed with suberect black setae over the entire surface; pronotal and elytral marginal fringe of longer erect black hairs which are not at all recurved. Integuments polished throughout.
THE COLEOPTERA OF SANTA CRUZ ISLAND, CALIFORNIA
Authors: Fall H. C. , Davis A. C.
Published: January 2010

The “List of the Coleoptera of the Southern California Islands—” published by the senior author in 1897 (Can. Ent. 29, 1897, 233-244) was the result of more or less sporadic collecting upon the Channel Islands by several parties, few of them trained collectors of insects.
TWO INTERESTING NEW BEES
Authors: Cockerell T. D. A.
Published: January 2010

The bees now described are of interest for different reasons. The genus Hesperapis, originally described from New Mexico, has been found to be widely distributed over the southwestern States, with eighteen species, two of which come from Lower California.
SOME UTAH LEAFHOPPERS.
Authors: Knowlton George F.
Published: January 2010

During the past few years it has been possible to collect leafhoppers in many parts of Utah. Because of the abundance of many of the species and the fact that so many feed upon range forage plants, it seems to the writer that the injury due to range leafhoppers in the Rocky Mountain West has been greatly underestimated.
