Head. Frontoclypeus and cheeks grayish white pollinose with rather long white hairs which are quite dense below; a small area in center of frontoclypeus denuded; also two very small denuded areas on the lower portion of each cheek; front above antennae grayish white pollinose shading to yellowish brown toward the vertex; front and vertex with many long black hairs. Frontal callosity brownish black and somewhat shining; about one half width of front.
AN APPARENTLY NEW EUPITHECIA FROM EASTERN NORTH AMERICA (GEOMETRIDAE: LEPID.)
Authors: McDunnough J.
Published: January 2010

In the course of my studies in this interesting genus I have gradually accumulated a few specimens of a species which on genitalic characters (both ♂ and ♀ ) is abundantly distinct from any of our other eastern species. As these genitalic characters of practically all the described species are known to me, due to a study of type material, I believe the present species to be undescribed and offer the following description.
CASE-BUILDING IN TRICHOPTERA AS AN INHERITED RESPONSE TO OXYGEN DEFICIENCY
Authors: Milne Margery J.
Published: January 2010

Many papers have been written about caddis cases, treating these movable shelters from the standpoints of choice of materials (Brues 1930, Dodds & Hisaw 1926, Lloyd 1915, Lutz 1930, Simpson 1903), of repair (Marshall & Vorhies 1905), of ontogenetic initiation (Murphy 1919, Copeland & Crowell 1937), and of phylogenetic origin (Milne & Milne, 1938). The last of these references, a paper by Sleight (1913) and the work of Dodds & Hisaw cited above, give some attention to the relation between case-building and the physiology of the larva inhabiting the structure, but much remains to be studied in this connection.
A CONTRIBUTION TO A LIST OF THE APHIDIDAE OF THE MARITIME PROVINCES OF CANADA
Authors: Burnham Jean C.
Published: January 2010

There has been to date, to the knowledge of the writer, no published list of the species of Aphididae common to the Maritime Provinces of Canada. It is proposed in the following contribution to make a beginning to such a list, with the hope that it may prove useful to interested taxonomists.
THE CHERMIDAE, (HOMOPTERA), OF ALBERTA
Authors: Strickland E. H.
Published: January 2010

The only published records of Chermidae captured in Alberta, which we have been able to find, refer to Psyllia americana Cwfd., Trioza varians Cwfd. both taken at Banff, and Paratrioza cockerelli Sulc., which has been, in recent years, accidentally introduced into the province.
STUDIES ON THE BIOLOGY OF THE EPHEMEROPTERA I. COLORATION AND ITS RELATION TO SEASONAL EMERGENCE
Authors: Spieth Herman T.
Published: January 2010

The following observations and conciusions are based upon ephemerids from temperate North America and principally upon material from the eastern United States. It is perfectly conceivable that in other parts of the world, where the fauna and also the environmental conditions are different, the conclusions reached here may not be applicable.
NOTES ON THE GENUS PROTARCHOIDES (HYMEN., ICHNEUMONIDAE)
Authors: Walley C. Stuart
Published: January 2010

The following notes were assembled in arranging the Protarchoides material in the National Collection. In establishing the identity of Protarchoides mellipes (Prov.) it has been found necessary to synonymize one species. A species allied to mellipes is described as new and a table is provided for the separation of the four known North American species. The recording of Trichiosoma as host for a member of this genus is further evidence of the close relationship of the genus with Protarchus Foer.
A NEW RACE OF BASILARCHIA ARCHIPPUS CRAMER FROM LOUISIANA (RHOPAEOCERA—NYMPHAEIDAE)
Authors: Dos Passos Cyril F.
Published: January 2010

The latest revision of the North American Basilarchia (Gunder, 1934, Can. Ent. LXVI: 39) recognizes three races of archippus Cramer (1779, Pap. Ex. I, t. 16 a, b) i.e. a. archippus inhabiting southern Canada and the Atlantic states as far south as North Carolina and west to Illinois, a. floridensis Strecker (1878, Cat. p. 143) found from South Carolina to the tip of Florida and a. obsoleta Edwards (1882, Fapilio 2: 22) occuring in Arizona, Utah and New Mexico.
BIOLOGICAL CONTROL OF INSECTS THROUGH PLANT RESISTANCE
Authors: Flint W. P. , Bigger J. H.
Published: January 2010

Both insects and man show marked preferences for certain strains or varieties of plants when these plants are used as food. This fact has been known for thousands of years as it applies to man, and has been just as true with respect to insects, though not fully appreciated. Go to any market where plant products are sold and you will find certain preferences (shown for special varieties; in fact, it will be difficult or impossible to sell other varieties of the same plant which, from the standpont of nutritive value, might be equal to the ones in demand.
SYNTHETIC ORGANIC COMPOUNDS USED AS INSECTICIDES
Authors: Roark R. C.
Published: January 2010

For many years chemists and entomologists have been seeking the hypothetical ideal insecticide, namely, a material which is toxic to insects at an economical dosage, which is not injurious to the host plant or animal sprayed or dusted with it, and which does not leave on foodstuffs a residue that is poisonous to man or domestic animals. Certain organic compounds approach closer to this ideal than any products of mineral origin, and the successful use of these against same of our most injurious insects has greatly stimulated the testing of countless organic products for insecticidal value.
NOTES ON THE EARLY STAGES OF SOME HESPERIINAE
Authors: Dethier V. G.
Published: January 2010

The following notes will serve to supply some of the desiderata listed by Scudder for the life histories of New England Hesperiinae. Descriptions are also given when they differ from those of Scudder or when they supplement his information. Detailed descriptions are given of Poanes hobomok Harr. because it has been impossible to determine which species Scudder described under the name Atrytone zabulon Insomuch as the ranges of the two species overlap, the two were confused as one at the time of Scudder's description and the source of his material is unknown.
SOME NEW CANADIAN CHRYSOMELIDAE
Authors: Brown W. J.
Published: January 2010

Length 3.7 mm.; width 1.7 mm. Body form as in palustris Blatch. Black; the elytra with a greenish lustre, not at all bluish: the basal half of the head, antennae, and legs pale red; the basal segment and four terminal segments of each antenna distinctly infuscate; femora and the apical half of each terminal tarsal segment heavily infuscate.
BLACKFLIES FROM UTAH AND IDAHO, WITH DESCRIPTIONS OF NEW SPECIES (SIMULIIDAE, DIPTERA)
Authors: Twinn C. R.
Published: January 2010

In 1934, Knowlton and Rowe (2) recorded five species of Simuliidae from Utah, including Simulium (Simulium) vittatum Zett., and four species described as new: namely, S. (S.) brevicercum, S. (S.) nigresceum, S. (Eusimulium) pilosum, and S. (E.) utahense. In May and October, 1937, G. F. Knowlton kindly forwarded to me for examination about seven hundred specimens of blackflies collected in various parts of Utah and Idaho. A study of this material showed that nine described species and six species new to science were represented. The distribution records and descriptions of the new species are given in the following pages.
A NEW SPECIES OF GYRINUS, WITH A NOTE ON DINEUTUS ROBERTSI LENG. (COLEOPTERA, GYRINIDAE)
Authors: Leech Hugh B.

A medium sized, polished black species, closely resembling picipes Aubé in general facies. Under side polished metallic black; legs dark, especially the middle and hind pairs.
SYNONYMIC NOTES ON AGLAIS MILBERTI (GODART) WITH THE DESCRIPTION OF A NEW SUBSPECIES. (LEPIDOPTERA-NYMPHALIDAE)
Authors: Dos Passos Cyril F.
Published: January 2010

Vanessa milberti Godart was described (1819, Enc. Meth. 9: 307, No. 25) from a specimen sent to the Paris Museum by the French painter and naturalist, Milbert, who visited the United States on one or more occasions early in the nineteenth century. Last summer, while in Paris, the type was photographed through the kindness of Dr. Le Cerf and this is reproduced on Plate 4, fig. I. Dr. Le Cerf informed the writer that the label was in the handwriting of P. H. Lucas who in 1860 re-labeled the collection, unfortunately destroying the original labels. This type is very badly worn so that today it might well pass for race furcillata Say for which reason the photograph of a typical specimen is also given (Plate 4, fig. 2).
MACROSIPHUM APHIDS INFESTING ARTEMISIA
Authors: Knowlton George F. , Allen Merlin W.
Published: January 2010

More than fifty species of aphids are already known to attack the numerous kinds of Artemisia occurring in western North America. Some aphids and their ant attendants occur in great abundance, virtually blackening the affected parts of the plants attacked. Artemisia is only one of many forage plant groups occurring in Utah which is damaged by aphids.
FOUR NEW NEARCTIC SPECIES OF FABRICIELLA, (TACHINIDAE, DIPTERA)
Authors: Reinhard H. J.
Published: January 2010

The genus Fabriciella, as considered by Tothill (Can. Ent., LVI, 1924:257-269) and Rowe (Ann. Ent. Soc. Am., XXIV, 1931 : 643-678), includes twenty-eight nearctic species. On the whole, the species are quite similar in general appearance, but in most cases readily separated, in the male sex at least, by genitalic characters.
A NEW CLEORID FROM SOUTHEASTERN CALIFORNIA (GEOMETRIDAE)
Authors: McDunnough J.
Published: January 2010

Differs from the typical section of the genus in the presence of a small fovea at the base of the male forewings (as in agrestaria Grossb.) and the lack of a hair-pencil on the hind tibiae in the same sex. Placed in this genus on account of the similarity of male genitalia, which are very close to those of serrataria B. & McD. as figured in my Studies in North American Cleorini.
FURTHER NOTES ON SOME ALTERNATIVE HOSTS OF THE ORIENTAL FRUIT MOTH PARASITE, GLYPTA RUFISCUTELLARIS CRESS
Authors: Putman WM. L.
Published: January 2010

In 1935, the writer published a preliminary paper on some alternative hosts of oriental fruit moth parasites, in which Glypta rufiscutellaris Cress. was recorded from an unknown leaf-tier on hawthorn in 1934. This species has since been identified by Dr. J. H. McDunnough as Epinotia sp., presumably laracana Kft. In the summer of 1935, G. rufiscutellaris was again reared from this host and an attempt was made to induce the emergents to parasitize oriental fruit moth larvae. Unfortunately, all but a single unfertilized female were destroyed by ants, but the survivor successfully parasitized newly hatched fruit moth larvae which were exposed in the cage on July 20 and 21, 12 male Glypta emerging from this material on August 19 to 25.
PTEROPHORID DESCRIPTIONS AND NOTES (LEPID.)
Authors: McDunnough J.
Published: January 2010

In a recent note (1938, Canadian Entomologist, LXX, 128) I suggested that this name should be applied in a strict sense to the species the larva of which feeds on Aster and Grindelia, but hesitated to separate the Balsamorrhiza feeder as a distinct species owing to lack of material; I had, however, called attention (1936, Canadian Entomologist, LXVIII, 63) to certain differences in the setal structure of the pupal cases which warranted further investigation.
NOTES ON THE APPEARANCE OF THE EUROPEAN EARWIG IN ONTARIO
Authors: McNally A. G.
Published: January 2010

In the early part of August, 1938, Professor Caesar, Provincial Entomologist, received from Kenneth C. Hume of Ayton, Ontario, a letter containing insects said to be numerous in that district. Professor Caesar identified these insects as the European earwig, Forficula auricularia L. This identification was later confirmed by the Dominion Entomologist from specimens forwarded by Professor Caesar when he reported the outbreak. This is the first recorded outbreak of the species in Canada east of the Rockies.
EARLY STAGES OF SOME HESPERIINAE
Authors: Dethier V. G.
Published: January 2010

Observations on the life histories of Polites verna Edw., Hesperia leonardus Harr., and Ancyloxypha numitor Fabr. are reported here. Previous work on the rare P. verna included a vague description by Scudder of a drawing of the egg and a full account of the last larval instar. Concerning H. leonardus only the egg and first instar were known. A drawing of the second instar was also described (Scudder, 1889). In a previous communication (Dethier, 1938) it was pointed out that the third brood of A. nomitor probably passed the winter in the larval stage. This is confirmed and further details presented.
A REVISION OF THE GENUS CAMPTOPROSOPELLA HENDEL (DIPTERA, LAUXANIIDAE)
Authors: Shewell G. E.
Published: January 2010

This paper has already received a partial introduction in a previous publication (Canadian Entomologist, LXX, 102) in which it was stated that a revision of this genus was contemplated in order to determine the status of two Eastern Canadian species. It only remains, therefore, to acknowledge the help that has been given me by the loan of specimens and in other ways, and to make a few remarks about the characters that have been utilized in the key and descriptions.
A REVISION OF THE GENUS CAMPTOPROSOPELLA HENDEL (DIPTERA, LAUXANIIDAE)
Authors: Shewell G. E.
Published: January 2010

Yellow. Legs concolorous with body or else apices of all tarsi light brown. Wing veins yellow. Dimensions: Body 3—3.5 mms. Wing 3—3.25 mms.

Front and face in profile the same as slossonae n. sp. with similar variation. Third antennal segment about twice as long as wide (1/2.0–1/2.3), infuscation subequal on both sides, covering apical fifth to third above and third to two thirds below. Arista with hairs arranged as in setipalpis n. sp. Infuscation of vertex roughly diamond-shaped, more or less pointed in front, longer than wide, not more than twice as long as triangle.
A NEW MEALYBUG PARASITE (HYMENOPTERA: SCELIONIDAE)
Authors: Muesebeck C. F. W.
Published: January 2010

The purpose of this paper is to provide a name for an undescribed species of the platygasterine genus Allotropa which has been encountered in Canada as a parasite of the mealybug Phenacoccus aceris (Sign.). Brief notes are also given on the single previously known Nearctic species of Allotropa and on another species which was erroneously described in that genus.
THE LIFE HISTORY OF ALLOTROPA UTILIS MUES., A HYMENOPTEROUS PARASITE OF THE ORCHARD MEALY BUG IN NOVA SCOTIA
Authors: Gilliatt F. C.
Published: January 2010

Soon after the discovery of the mealy bug Phenacoccus aceris Sig. in the orchards of Nova Scotia in 1932, a parasite of much importance was found attacking this pest. This is a small hymenopterous species described in this issue by Dr. C. F. W. Muesebeck as a new species, Allotropa utilis Mues.
SOME GYNANDROMORPHS OF EPHEMEROPTERA
Authors: Spieth H. T. , Ide F. P.
Published: January 2010

Gynandromorphs have been reported from many orders of insects and especially from those orders in which large numbers of individuals have been collected or reared. It is therefore not surprising that, with the accumulation of large scries, ephemerid gynandromorphs should be found occasionally and it seems advisable to put descriptions of such individuals on record. Needham, Traver, Hsu, etc.
A NEW SPECIES OF IPS (COLEOPTERA, SCOLYTIDAE)
Authors: Hopping Ralph
Published: January 2010

The small group of the genus Ips placed at the end of Dr. Swaine's key seems to have a character not found elsewhere in the genus. The epistomal region, in the males, is elevated and often has a dense brush of hairs which make the elevation look greater than it really is. However, this brush is often rubbed until it has entirely disappeared. This has apparently given rise to the idea that two entirely different females are associated with the males in the same gallery.
NOTES ON THE DISTRIBUTION OF PLEBEIUS AQUILO BDV. WITH THE DESCRIPTION OF A NEW RACE FROM MANITOBA (LEPID. LYCAENIDAE)
Authors: Freeman T. N.
Published: January 2010

In different regions of North America, Plebeius aquilo Bdv. varies considerably in size and maculation and appears to be differentiated into at least six geographical races. The distribution of each of these known races is roughly outlined in the accompanying diagram, and the localities marked are represented by specimens in the Canadian National Collection.
SCOTOCHROA AND A CLOSELY ALLIED NEW GENUS, SCOTOCHROIDES, (COLEOPTERA, MELANDRYIDAE)
Authors: Mank Edith W.
Published: January 2010

The Leng check list (1920) records under Scotochroa, which is a distinctly American genus established by Leconte in 1874, two species, S. atra Lec. and S. basalis Lec. Scotochroa buprestoides Kirby (described in 1837 as a Xylita) is listed under atra, indicating it as either a synonym or as being questionable as a valid species. The Csiki Catalogue of the Serropalpidae (1924) lists one species, atra, under Scotochroa with buprestoides given under this and with basalis as a variety. The Supplement of the Leng list (1927) records basalis as a variety of atra. The general question as to the species in this group seems to warrant a review of the genus with a key to the species.
A METHOD OF MOUNTING ENTOMOLOGICAL SPECIMENS IN GELATIN
Authors: Andison Harry
Published: January 2010

The use of gelatin as a medium in which to mount and permanently preserve biological specimens is by no means new; it was advocated by Lee at least fifty years ago. It is only within the last ten years, however, that its usefulness as a practical method for preserving entomological material has been realized. Its application to insect work was first suggested by Prof. L. J. Muchmore of the Southwest Museum, Los Angeles. California, to H. C. Lewis, who reported on the subsequent development of the technique in 1929.
NEW NORTH AMERICAN GEOMETRIDAE WITH NOTES, I (LEPID.)
Authors: McDunnough J.
Published: January 2010

Similar in wing shape and in the possession of a double areole on primaries to Euacidalia Pack. Palpi short; male antennae finely ciliate. In the male hind-legs the tibiae are very broad and long (twice the length of the tibiae in Euacidalia), rather flattened with strong hair pencil, without spurs and projecting apically over the first joint of the tarsi. Tarsi extremely short and attached to the ventral surface of the tibiae.
THE GENUS ILYBIUS ER. IN NORTH AMERICA (COLEOPTERA, DYTISCIDAE)
Authors: Wallis J. B.
Published: January 2010

In spite of Mr. H. C. Fall's paper on Ilybius in the “Entomological News”, XXXVIII, 1927, much confusion as to the correct identification of species in that genus is still apparent. Nor is this to be wondered at. One species frequently superficially resembles another so closely that only careful discrimination will make certain what is in hand. Further, to my knowledge, no key by which females can be determined has been devised. This latter deficiency I have endeavoured to remedy.
THE PLECOPTERA OF WESTERN MONTANA
Authors: Castle Gordon B.
Published: January 2010

The streams and lakes of western Montana offer a variety of habitats for species of aquatic insects but heretofore extensive collection and study of these forms has not been undertaken. During the past two years collections of both nymphs and adults have been made on several streams. The Plecoptera in these collections include the undescribed nymphs of Nemoura cinctipes Banks and several species which have not been reported for Montana.
REMINISCENCES OF THE EARLY DAYS OF THE SOCIETY
Authors: Dearness John
Published: January 2010

The lateness of the hour will prevent my taking time to add to Professor Baker's admirable history many personal recollections of the founders of the Society and of its early activities. Dr. W. E. Saunders, the secretary for a number of years, and I belong to the second generation of active members; however for a period of fifteen or more years we were associated with the pioneers who well and truly laid the foundation of the Society.
NEW PSYLLIDS FROM ALBERTA (PSYLLIDAE, HOMOPTERA)
Authors: Caldwell John S.
Published: January 2010

The following dexriptions are based on specimens collected by Mr. E. H. Strickland in Alberta, Canada. All holotypes and allotypes are deposited in the Canadian National Collection at Ottawa, Ontario. Paratypes are in the collection at the University of Alberta, Edmonton, and in the Caldwell collection at Ohio State University, Columbus.
A NEW RACE OF PAPILIO BELONGING TO THE MACHAON COMPLEX
Authors: McDunnough J.
Published: January 2010

For years several specimens of a Papilio form from Alberta, allied to oregonia Edw., have stood apart in the Canadian National Collection. Time and again I have puzzled over them but could never make them fit exactly under any of the existing names. Three of the series (males) came to us with the Wolley-Dod collection and were captured in 1905 in the bad lands of the Red Deer River Valley, somewhere near Drumheller; a fourth specimen (a female) was taken in the same general region in 1917 by C. H. Young.
EXPLORATIONS OF THE HYPOPHARYNX IN NOCTUID LARVAE
Authors: Gilbert H. A.
Published: January 2010

While making a study of the larvae of certain species of Noctuidae, the writer was impressed by differences observed in the structure of the hypopharynx. A survey of the literature reveals that, though some workers have paid a certain amount of attention to this organ in larval Lepidoptera, the literature on the subject is not extensive.
THE USE OF A BAMBOO POLE DRAG IN ENHANCING THE VALUE OF DUSTS IN THE CONTROL OF THE PEA APHID
Authors: Maltais J. B.
Published: January 2010

The pea aphid infestation at Howick, Aubrey and Brysonville, Quebec, was severe in 1938. On June 28, complete commercial dusting equipment and a sufficient amount of rotenone-bearing dust were brought to the fields for the treatment of peas against the insect.

THE TERMITE, AN OBJECT LESSON
Authors: Cory Ernest N.
Published: January 2010

Most of the information in regard to termites has come as a result of efforts to combat their destructive activities. In these studies an amazing story of social organization and biological adaptation that has fascinated students in sociology, political science, and engineering, as well as entomologists, has been unfolded.
NEW BRITISH COLUMBIAN EPHEMEROPTERA
Authors: McDunnough J.
Published: January 2010

During the first week of August, 1938, my assistant in British Columbia, Mr. J. K. Jacob, was fortunate in being able to join a party which was penetrating into the little known and rather inaccessible mountain region west of Lytton and the Fraser river. A start was made at the junction of Kwieek Creek and the Fraser river, near the railway station of Boston Bar, about 10 miles south of Lytton; from here the route followed up the creek to Blue Lake situated at an altitude of 7000 feet, at the base of Antimony Mt., where the main camp was pitched.
A PAPAIPEMA FROM ARIZONA (LEPIDOPTERA)
Authors: Bird Henry
Published: January 2010

When economic entomology concerns itself in the line of biological control further than the introduction of foreign parasites to offset the inroads of introduced pests and turns for help to our indigenous hordes of balancing agents, as it must do some day, college professors may well direct their students to Papaipema biologies. Here an easy exposition of what holds a large genus to innocuous bounds is amply portrayed and, as hosts to such a retinue which goes still further afield, proclaims them in fact helpful species of our biota.
NOTES ON SYMPISTIS KOLTHOFFI AURIV. AND SYMPISTIS ZETTERSTEDTI LABRADORIS STAUD. FROM CHURCHILL, MANITOBA (LEPID. PHALAENIDAE)
Authors: Freeman T. N.
Published: January 2010

Sympistis kolthoffi Auriv. originally described from Greenland (1890, Anarta kolthoffi Aurivillius, Bihand Till. K. Sv. Vet.-Akad. Handl., XV, 20, pl. 2, fig. 1) as a race of the European S. zetterstedti Staud., and has not been previously recorded from North America. Specimens of kolthoffi from Churchill, Manitoba, agree very favorably with the original description and figure, and appear specifically distinct from specimens of labradoris from the same and other Canadian localities.
THE RELATION OF TECHNICAL TRAINING TO APPLIED ENTOMOLOGY IN THE COMMERCIAL FIELD
Authors: Davis J. J.
Published: January 2010

The topic which I am to discuss was not of my own choosing but was assigned to me by your program committee. This is my alibi and I just wanted you to know whom to blame. I am assuming the program committee referred to training for service as pest control operators, commonly called exterminators, although the title assigned might include other fields.
A PLEA FOR PRESERVATION OF THE SOUTH POINT OF PELEE ISLAND AS A WILD-LIFE-STUDY PRESERVE
Authors: Kennedy Clarence Hamilton
Published: January 2010

My reason for asking scientific men in Canada to do something for their own future good is somewhat selfish. For eighteen summers I have taught classes in entomology at the Franz Theodore Stone Laboratory on Gibraltar Island at Put-in Bay, Ohio. This is a department of the Ohio State University definitely devoted to a study of the aquatic resources of Lake Erie and associated waters.
A CORRECTION IN THE TRYPHONINAE (HYMENOPTERA: ICHNEUMONIDAE) IN DALLE TORRE'S CATALOGUS HYMENOPTERORUM
Authors: Bradley J. Chester
Published: January 2010

C. G. de Dalle Torre (Catalogus hymenopterorum, vol. 3, p. 24) makes the following erroneous entry:

“Plectiscus pleuralis (Cress.) Davis—♀—Am. New Jersey.

Tryphon pleuralis Cresson, Proc. Entom. Soc. Philadelphia. III. 1864, p. 275 n. 5, ♀.

THE CORRECT GENERIC POSITION AND SYNONYMY OF SYMPHOBUS PLEURALIS (CRESSON) AND OF PLECTISCUS PLEURALIS PROVANCHER (HYMENOPTERA: ICHNEUMONIDAE).
Authors: Townes Henry K.
Published: January 2010

The genotype of Symphobus is Tryphon pleuralis Cresson, and that of Oetophorus is Mesoleius stretchii Cresson. I have studied the types of each of these species and find them congeneric. Symphobus was described originally without included species and pleuralis is the first species to be referred to it. Pleuralis has pectinate claws and in that respect does not fit the original description of Symphobus.
A NEW RACE OF LYCAENA DORCAS FROM NORTHEASTERN NEW BRUNSWICK
Authors: McDunnough J.
Published: January 2010

In the same salt meadows north of Bathurst, N. B., where Mr. Brown and I captured the recently described race of Coenonympha inornata (1939, Can. Ent., LXXI, 266) we took a series of specimens of L. dorcas Kby. which on examination, after spreading, appears to constitute an undescribed and rather strikingly different race. The butterflies were by no means common; the first specimens were taken on August 6, evidently freshly emerged, and by dint of careful searching during the next four or five days we were able to capture a series of about 50 specimens.
A SYNOPSIS OF THE NORTH AMERICAN SPECIES OF SYNDIPNUS (HYMEN., ICHNEUMONIDAE)
Authors: Walley G. Stuart
Published: January 2010

As noted below the two North American species described in Syndipnus by workers appear to belong in other genrra. In Europe the gunus is represented by nearly a score of species and has been reviewed in recent years by two writers (1, 2). North American collections contain very few representatives of the genus; after combining the material in the National Collection with that from the United States National Museum, the latter kindly loaned to me by Mr. R. A. Cushman, only thirty-seven specimens are available for study.
TWO APPARENTLY UNDESCRIBED SPECIES OF GEOMETRIDAE FROM THE SOUTHWEST

The use of oil sprays has proved of value in grasshopper control operations on the open range lands of British Columbia under certain specific conditions.

Only when a species, such as Camnula pellucida (Scudder), which deposits it eggs in definite egg-beds which have heen definitely located and staked during the previous summer, or when nymphs or adults are concentrated in very large numbers in small depressions or, as in the case of Melanoplus mexicanus mexicanus (Saussure), on tall weeds, and when weather conditions are not favourable for poisoning, is the use of oil sprays justified as an adjunct to the regular poisoned bait campaign.
NEW RECORDS AND NOTES OF ORTHOPTERA IN ONTARIO
Authors: Walker E. M. , Urquhart F. A.
Published: January 2010

It is the purpose of this paper to add a few hitherto unreported species of Ontario Orthoptera to the list of those already recorded for the province. The majority of the species here recorded were taken by the junior author in Essex County in the extreme southwestern portion of the province of Ontario and are the result of an expedition sponsored by the Royal Ontario Museum of Zoology.
UNDESCRIBED SPECIES AND RACES OF PHALAENIDAE (LEPID.)
Authors: McDunnough J.
Published: January 2010

Much paler in the ground-color of the forewing than the typical form, the olive-gray shades being replaced by whitish; this is particularly evident between the reniform and apex of wing and along the inner margin. The broad blackish shading through central portion of wing from base to outer margin is heavy and a similar shade patch occurs on costa above the orbicular and reniform; the former is filled with white and in consequence is quite a prominent feature of the maculation, the latter is also largely white-filled with a slight ochreous shade in central portion and a strong black border-line on basal side. Secondaries almost pure white with faint traces of smoky terminal shading (somewhat more pronounced in the female) and indications of a smoky postmedian line in costal half of wing. Expanse 35 mm.
MODIFIED RIKER INSECT MOUNT FOR USE IN TEACHING
Authors: Smith Ralph H.
Published: January 2010

Effective instruction in entomology requires, among other things, that the student have the opportunily to see and examine to his satisfaction the insects dealt with in the course. This statement applies not only to courses in systematic and taxonomic entomology but to introductory courses and to such courses as field crop insects, truck and garden insects, stored product insects, fruit and nut insects, household insects, forest insects, medical entomology and the like. Surely, the instruction is seriously deficient where the student's acquaintance with the insects is limited to what he may hear in a lecture, or read or see in illustrations in a book.
NOTES ON THE ROSE STEM GIRDLER, AGRILUS COMMUNIS RUBICOLA AB.
Authors: Garlick W. G.
Published: January 2010

The rose stem girdler (Agrilus communis rubicola Ab.), a pest of European origin, was first recorded on this continent in 1913. The earliest report of its presence in Ontario was made in 1931 in the Windsor area by Mr. C. S. Thompson, formerly of the Dominion Plant Inspection Service, who found it infesting roses on private grounds. The roses had been obtained in 1929 from a Michigan nursery which had imported them from Holland.
A METHOD OF MOUNTING SMALL BEETLE GENITALIA
Authors: Swank George R.
Published: January 2010

While studying some of the smaller coccinellid beetles a method of mounting the genitalia has been developed which can probably be applied to many other groups with slight modifications.

Wilson (1930) has given a somewhat similar method for removing the genitalia from the beetle without the complete destruction of the specimen and mounting them in cardboard rectangles.
THE TECHNIQUE OF RANDOMIZATION IN FIELD WORK
Authors: Beall Geoffrey
Published: January 2010

Field workers are frequently faced with the necessity of making some sort of randomization. Thus randomization is today one of the conditions of trials in plots of, say, fertilizers or insecticides. Again, randomization is often attempted in sampling work, as when the number of insects in a plot or a field is to be ascertained from an incomplete examination; generally, when not attempted, it is by omission on the part of the investigator.
ON SOME CHILOPODS AND DIPLOPODS FROM NORTH CAROLINA
Authors: Chamberlin Ralph V.
Published: January 2010

In several small collections of myriopods recently made in North Carolina, and chiefly in the Duke Forest at Durham, by Mrs. Nelle Bevel Causey, and by her transmitted to me for identification, occur representatives of the species listed below. The purpose of the present paper is primarily to diagnose the several new forms represented; bur because of the interest of some of the other records it seems desirable to give the complete list here as supplementary to the catalogue of forms previously known from the region. The types of the new species are retained in the author's collection.
NOTES ON THE GENUS PERONEA WITH DESCRIPTION OF A NEW SPECIES (LEPID., TORTRICIDAE)
Authors: McDunnough J.
Published: January 2010

Since the publication of my revision of the North American species of this genus, the food-plants of the larvae of several species, at the time unknown, have been ascertained. The recording of these, together with a few other notes that have been made from time to time in the course of identification work, form the basis of the present paper.
AN ADAPTION OF A STANDARD BI-METALLIC THERMO-REGULATOR TO CONTROL VARIABLE TEMPERATURES
Authors: Wishart Geo.
Published: January 2010

In entomological investigations it is frequently desirable to use varying temperatures rather than constant temperatures. The apparatus herein described, when installed in a rearing or storage chamber, makes it possible to control temperatures in any desired graph pattern over a period of twenty-four hours, and to repeat the same pattern any desired number of times. This is accomplished by removing the usual adjusting mechanism from a DeKhotinsky-thermo-regulator and substituting for it an automatic adjuster operated by a synchronous electric clock.
NOTES ON THE MORPHOLOGY, LIFE HISTORY, AND ECONOMIC IMPORTANCE OF SMICRONYX UTILIS BUCHANAN. (COLEOPTERA, CURCULIONIDAE)
Authors: Rempel J. G. , Shevkenek Wm.
Published: January 2010

Smicronyx utilis is a small curculionid beetle which in Saskatchewan breeds in the seeds of Iva axillaris Pursh., or poverty weed. The weed is a native perennial found from the Saskatchewan-Manitoba border to British Columbia and south to Mexico. Although not as prevalent as some of the other bad weeds, it is one of the most persistent and one of the most difficult to eradicate. Owing to the fact that, in Saskatchewan, the percentage of infestation in well-developed seeds is very high, the plant appears to spread by rootstocks only. This facilitates eradication considerably.
A PARTITION OF OUR CRYPTOCHILUS, WITH SOME NEW PSAMMOCHARIDAE (HYMENOPTERA)
Authors: Banks Nathan
Published: January 2010

The genus Cryptochilus is based on C. annulatus Fabr., a Mediterranean species; the pleura has numerous sharp carinae, the propodeum is striate, the antennae are fairly slender, the clypeus rather broadly concave below, the first recurrent vein ends near the tip of the second submarginal cell, the pronotum, seen from side, shows an even curve from behind down to the collar. Some other European species have the pleura less strongly striated. Several of our species agree fairly well in these characters; however there are others that show various differences.
THE PULVERULENTA GROUP OF THE GENUS PSEUDANARTA GROTE (LEPIDOPTERA, PHALAENIDAE, CUCULLIINAE)
Authors: Franclemont J. G.
Published: January 2010

After Barnes and Benjamin transferred pulverulenta Smith to Pseudanarta Grote (Pan-Pacific Entomologist, III, 110-111, 1927), it was thought that the matter ended there, as the species had obviously been referred to the correct genus. However, in the course of working over the Cuculliinae, a number of slides of the genitalia of this “species” were made, and these exhibited constant differences, which made me believe that we were dealing with a group of species and not one.
NOTES ON THE BIONOMICS OF THE MILKWEED BEETLE TETRAOPES TETROPHTHALMUS (FORST.) (CERAMBYCIDAE)
Authors: Williams R. W.
Published: January 2010

There are several controversial questions in the literature pertaining to the life history of the milkweed beetle, Tetraopes tetrophthalmus. I made an attempt to find the solution to some of these questions during the fall of 1939 and spring and summer of 1940. The results of this study are offered herewith. The milkweed hosts of this insect were abundant along railroads near Urbana, and it was largely in such situations that these investigations were carried out.
NEW SPECIES OF TRICHOPTERA FROM CANADA AND NORTHERN UNITED STATES
Authors: Ross Herbert H.
Published: January 2010

Most of the species described in this paper have been sent to me for identification by various students of limnology to whom I wish to express my appreciation for their cooperation. Types are in the collection of the Illinois State Natural History Survey, unless otherwise stated. I am indebted to Dr. C. O. Mohr of the Survey for considerable assistance with the drawings.
SOME APPARENTLY UNDESCRIBED COLEOPHORIDAE FROM THE OTTAWA REGION (LEPID.)
Authors: McDunnough J.
Published: January 2010

In a recent paper (1940, Trans. Roy. Soc. Can. Sec. V, 53) I emphasized the importance of the genitalia in determining species in Group A of the genus Coleophora, i. e. (according to Barasch) those species in which the aedeagus is strengthened with lateral rods of chitin. In this large group it will frequently be found that several species possess an almost identical type of maculation and cannot satisfactorily be separated on this character alone with any degree of certainty; the genitalia in both sexes, however, provide excellent means of separation.
SOME NEW AND LITTLE KNOWN CANADIAN ICHNEUMONIDAE (HYMENOPTERA)
Authors: Walley G. Stuart
Published: January 2010

Resembles ellopiae Hgtn. in structure and sculpture, but with abdomen entirely black, not red as in that species. In Cushman's and Townes's synopses it traces to sodalis Ruthe, which it resembles in color, but from which it differs in its rounded, rather strongly receding temples, shorter malar space, narrower ocellocular space, very narrow epipleura of abdominal segments two, three, and four, the absence of median longitudinal propodeal carinae, and the much paler color of the wings.
SOME NEW SPECIES OF THE GENUS SCIARA FROM CANADA
Authors: Shaw F. R.
Published: January 2010

In a collection of Mycetophilidae taken by H. E. McClure in Manitoba during the summer of 1936, there are two new species of the genus Sciara. The following are the descriptions of these new species.
ON THE TAXONOMIC STATUS OF GILPINIA POLYTOMA (HTG.) AND G. HERCYNIAE (HTG.) (HYMENOPTERA, DIPRIONIDAE)
Authors: Reeks W. A.
Published: January 2010

The species known in America as the European spruce sawfly has been shown to be one of two species which have been confused under the name Gilpinia polytoma (Hartig) (1). One is arrhenotokous and is known only from Europe, and the other is thelytokous and occurs in Europe and America. This paper seeks to establish the correct nomenclature and provide adequate descriptions of the two species.
EUPITHECIA NOTES, II
Authors: McDunnough J.

As a result of further studies of Eupithecia species chiefly in connection with their genitalia, the following notes have accumulated. As they may be of some certain interest to other workers in the group, I am publishing them at the present time.
THE GENERIC NAME THERMONECTUS DEJEAN (COLEOPTERA, DYTISCIDAE)
Authors: Leech Hugh B.
Published: January 2010

American students have long used the name Thermonectes Crotch, 1873 (Trans. Amer. Ent. Soc., 4:402), for a genus of dytiscid beetles, and have accepted Crotch's designation of Acilius ornaticollis Aubé, 1838, as the genotype. This treatment overlooks three earlier references which establish a generic name for the same natural group of species.
SEPARATION OF THE EUROPEAN SPRUCE SAWFLY IN AMERICA FROM GILPINIA POLYTOMA (HTG.) (DIPRIONIDAE, HYMENOPTERA) AND EVIDENCE OF ITS INTRODUCTION
Authors: Balch R. E. , Reeks W. A. , Smith S. G.
Published: January 2010

The discovery of the “European spruce sawfly” in Canada in 1930 and the development of its destructive outbreak have been described (3). It was identified in 1931 as Diprion polytomum (Htg.), which became Gilpinia polytoma (Htg.) in 1939 as a result of Benson's revision of the genera of the Diprionidae. The work of parasite introduction (1) commenced immediately on the assumption that the insect was an importation from Europe.
NEW NEARCTIC CRANE-FLIES (TIPULIDAE, DIPTERA). PART XVI
Authors: Alexander Charles P.
Published: January 2010

The preceding part under this general title was published in 1941 (Can. Ent., 73:85-90). The majority of the novelties discussed herewith were collected by myself in the mountains of Colorado; for other specimens I am indebted to Professor Harry C. Severin, South Dakota State College; Dr. Charles D. Michener, University of California; and Dr. Alan Stone of the United States National Museum. Where not indicated to the contrary the types of the novelties are preserved in my extensive collection of these flies.
ON THE GENUS PETALODES, WITH DESCRIPTIONS OF TWO NEW NORTH AMERICAN SPECIES (HYMENOPTERA, BRACONIDAE)
Authors: Walley G. Stuart
Published: January 2010

The discovery of an interesting species of Petalodes in a lot of Braconidae taken in British Columbia prompted the writer to submit a specimen to Dr. C. F. W. Muesebeck of the United States National Museum, for his opinion on the species, which from the literature seemed to be quite close to the genotype, Petalodes unicolor Wesm., of Europe.
IRON FRAUDATOR TRAVER VS. IRON PLEURALIS BANKS (EPHEMERIDA)
Authors: Bartlett Lawrence M.
Published: January 2010

McDunnough (1938, pp. 32-33) has raised the question of the validity of Iron fraudator Trar. A specimen sent to him by Dr. Traver as the true pleuralis was treated with caustic potash and mounted in balsam. This “proved……..identical with a genitalic slide made from a male paratype of fraudator, Trav.……..Other slides of similarly distorted material……..gave similar results.” Spieth (1938, pp. 7-11) has also questioned the validity of I. fraudator, giving additional evidence that this species is, in reality, a stage of I. pleuralis in which the penes have become expanded.
TWO NEW SPECIES OF TICKS FROM BRITISH COLUMBIA (IXODIDAE)
Authors: Gregson J. D.
Published: January 2010

Two new species of Ixodes are described herewith. Both have been recognized for the past ten years as differing in certain respects from known species. Published descriptions of them, however, have been withheld pending a fuller knowledge of their distribution and further studies on the stability or certain differences between them and allied species. The acquisition of further study material having shown that differences are constant, the writer now feels justified in erecting two new species, thus differentiating these ticks from allied species with which they have been confused.
THE NYMPH OF AESCHNA VERTICALIS HAGEN
Authors: Walker E. M.
Published: January 2010

Aeschna verticalis Hagen has been for some years the only species of the genus from eastern North America, whose nymph was unknown, except the rare A. mutata Hagen. At last, unexpectedly, the writer found A. verticalis in transformation at Clementsport, Annapolis Co., Nova Scotia.
THE HIPPELATES FLIES OR EYE GNATS: PRELIMINARY NOTES
Authors: Sabrosky Curtis W.
Published: January 2010

The Hippelates flies or eye gnats are dipterous insects of considerable interest to medical entomologists and public health workers because of their relation to the transmission of yaws and epidemic eye diseases, and because of their persistently annoying habits. The writer has been engaged in studies leading to the preparation of a comprehensive, illustrated monograph of the group in the western hemisphere, a work long needed because of the close similarity of the many species and the difficulty of proper determinations from the literature.
TESTS FOR TOXICITY OF ARSENICALS AND SODIUM FLUORIDE TO THE AMERICAN ROACH, PERIPLANETA AMERICANA L.
Authors: Sweetman Harvey L.
Published: January 2010

It has been recognized for some time that certain stomach poisons act as contact poisons also. O'Kane and Glover (1935) were among the first to demonstrate that arsenic penetrates the integument of roaches. They give a brief historical account of work preceding 1935. Sodium fluoride has been recommended in this country as an insecticide for the control of roaches since 1915 (Marlatt).
NEW RECORDS OF ODONATA FROM MANITOBA
Authors: Walker E. M.
Published: January 2010

Since the writer's list of the Odonata of Manitoba was published, six species have been added to the fauna of this province and the ranges of some of the species already listed have been considerably extended. Most of these new records are based on the following collections:

1. Forty-four specimens from Churchill, on the coast of Hudson Bay (58°50' N. Lat.), collected in 1936 by Mr. H. Elliott McClure and submitted for identification to the writer by Professor B. Elwood Montgomery of Purdue University, Lafayette, Indiana. All of these with the possible exception of one species were taken on July 18 and are labelled “Bush.”
