NOTES ON EARLY STAGES OF CERTAIN CANADIAN MICROLEPIDOPTERA
Authors: McDunnough J.
Published: January 2010

In the months of June and July field work was carried on by myself in western Nova Scotia at the following localities—Annapolis Royal in the Annaapolis Valley, South Milford in the interior and White Point Beach on the south shore near Liverpool. A number of life histories of various Microlepidoptera were worked out and data on the early stages secured. I offer the following notes on several of these species concerning which, as far as I know, our knowledge is very fragmentary. As in a previous work of this nature (1933, Can. Jour. Res. IX, 502-517) I have checked as far as possible both Fracker's larval classification (1915, Ill. Biol. Mon. II) and Mosher's work on the pupae (1916, Bull. Ill. Sta. Lab. Nat. Hist. XII, Art. 2).
THE INFLUENCE OF UNFAVOURABLE FEEDING CONDITIONS ON THE SURVIVAL AND FECUNDITY OF ORIENTAL FRUIT MOTHS
Authors: Dustan G. G.
Published: January 2010

In connection with our studies on the Oriental fruit moth, large numbers of the insect are reared in the insectary on apples. The fruit moth eggs are placed on apples in closed containers such as No. 10 tins, and when the larvae are mature the majority of them come to the top of the containers and are placed on strips of corrugated paper in lantern globes for pupation and emergence.The remaining larvae are allowed to pupate and emerge in the rearing containers.
NOTES ON THE HABITS OF ATTACK OF THE HEMLOCK BORER
Authors: Balch R. E.
Published: January 2010

The hemlock borer (Melanophila fulvoguttata Harr.) belongs to a buprestid genus, the larvae of which bore in the bark and cambial area of the stems of conifers. They generally breed in trees which have been weakened. injured, or recently felled. Several species, however, including fulvoguttata, are reported to be capable of attacking and killing healthy trees and doing a large amount of damage. In other words, they belong to that class of cambial feeders which normally finds conditions most favorable when the host is about to die, but occasionally appears to be capable, when numerous, of breeding in healthy trees which would otherwise live. They are faculative tree killers.
COMMENTS ON MARTEN'S SPECIES OF TABANIDAE (HORSEFLIES) FROM WESTERN UNITED STATES
Authors: Philip Cornelius B.
Published: January 2010

In the Canadian Entomologist (1882 and 1883) Marten describes 7 species of Tabanus from the western United States of which the location of the types is unfortunately unknown. Certain characters now considered essential for comparative analysis were not adequately treated by him and as the descriptions were apparently based on damaged specimens in 2 instances, and on very restricted numbers in others, some confusion has arisen as to the identity of certain of these species.
NOTES ON WESTERN SPECIES OF EPHEMEROPTERA
Authors: McDunnough J.
Published: January 2010

As our knowledge of the western Ephemerid fauna, particularly in its nymphal stages, increases, cur conception of the individual species becomes more accurate, necessitating in some instances corrections of previous statements, and enabling us to differentiate closely allied species in various groups which here-tofore had been lumped under one name. The basis for the following notes has been the rearings carried on by my assistant, Mr. A. N. Gartrell, in the Okanagan region of British Columbia in 1934.
CAPITOPHORUS APHIDS INFESTING CHRYSOTHAMNUS
Authors: Knowlton G. F. , Smith C. F.
Published: January 2010

In view of the abundance, wide distribution, and forage value of some of the rabbit brush species in western North America and the lack of knowledge concerning the range entomology of this region, it was felt that a study of the Capitophorus aphid fauna of this plant would be desirable.
NOTICE OF POSSIBLE SUSPENSION OF RULES OF NOMENCLATURE IN CERTAIN CASES
Authors: Stiles C. W.
Published: January 2010

Attention of the zoological profession is invited to the fact that request for the “Suspension of the Rules” has been made in the following cases, on the ground that “the strict application of the Règles will clearly result in greater confusion than uniformity.” According to procedure one year's notice is hereby published, “making it possible for zoologists, particularly specialists in the group in question, to present arguments for or against the suspension under consideration.”
PAPAIPEMA STENOSCELIS DYAR, A RARE NOCTUID OF THE EASTERN UNITED STATES. (LEPIDOPTERA)
Authors: Bird Henry
Published: January 2010

When the foodplant is known as well as some outlook on biological happenings, Papaipema species for the most part are quite easily secured when bred through to the adults. To meet with them other than larvae or pupae is another matter, and except for a few, they classify as uncommon insects
ON THE OCCURENCE OF A COSTAL VEIN IN THE GENUS ARCHONIAS HBN. (LEPIDOPTERA:PIERIDAE)
Authors: Chadwick Leigh E.
Published: January 2010

In the course of a series of dissections of various species of Pieridae, the author noticed what appeared tobe a costal vein in the forewing of a specimen of Archonias bellona Cramer. Further examination showed that there was indeed a costal vein present here, and this prompted a scrutiny of a considerable body of material in this ganus and others allied to it, the results of which are given in tabular form below.
NOTES ON THE INTRODUCTION OF DIPRION PARASITES TO CANADA
Authors: Finlayson L. R. , Reeks W. A.
Published: January 2010

Preliminary study of the outbreak of the European spruce sawfly (Diprion polytomum Htg.) in the Gaspe Peninsula, undertaken in 1931 by the Division of Forest Insects, showed that the extent of the infestation was such that the sawfly could not be economically controlled by chemical or mechanical means. It was found, also, that the sawfly was not attacked by parasites.
THE LIFE HISTORY OF CALEPHELIS BOREALIS (LEPIDOPTERA)
Authors: Dos Passos Cyril F.
Published: January 2010

Until quite recently, nothing seems to have been accomplished toward solving the life histories of any NorthAmerican species grouped in the genus Calephelis Grote & Robinson, but in 1928 (Bull. So. Calif. Ac. SC. XXVII: 80) and 1932 (Bull. So. Calif. Ac. Sc. XXXI :12) those indefatigable students of the preparatory stages of Californian lepidoptera, Dr. John A. Cornstock and Commander Charles M. Dammers, published the life histories of C. australis Edwards and C. nemesis Edwards, illustrated in their usual beautiful manner.

On July 17th, 1932, while collecting lepidoptera with Mr. Frank E. Watson near Newton, New Jersey, he took our first specimen of C. borealis Grote & Robinson in a field near the edge of an open woods. Further search resulted in the capture of eleven more specimens, all in the woods, in this respect confirming the habitat mentioned by Dr. A. F. Brower (1929 Ent. News XL :125).
A REPORT ON SOME BRACONIDAE FROM BAFFIN ISLAND (HYMENOPTERA)
Authors: Walley G. Stuart
Published: January 2010

During late July and August, 1935, Mr. W. J. Brown made extensive insect collections at Lake Harbour, a trading post on the southern coast of Baffin Island. The following is a report on the Braconidae taken by Mr. Brown. Specimens of this family were comparatively rare and only six species were encountered. Two of these are represented by single males and cannot be positively identified at present. The material is deposited in the Canadian National collection; duplicate paratypes of new species are deposited in the United States National Museum.
THE FLEAS OF BRITISH COLUMBIA
Authors: Wagner Julius
Published: January 2010

The present article is based on a study of the collection of fleas belonging toProf. G. J. Spencer, of the University of British Columbia, Vancouver, B. C., and of the collections made by the late Mr. Eric Hearle of the Dominion Entomological Laboratory, Kamloops, B. C. It is an agreeable duty to me to express my most sincere gratitude to Prof. G. J. Spencer as well as to Dr. Arthur Gibson, Dominion Entomologist, and Dr. J. McDunnough, Chief ofthe Division ot Systematic Entomology, Entomological Branch, Department of Agriculture, Ottawa, Ont., for havingafforded me the opportunity of becoming more closely acquainted with the aphanipterological fauna of British Columbia. It was especially interesting to me as the fauna of this province is largely allied to that of the eastern part of the palaearctic region.
A NEW SCHIZOPYGA FROM CANADA (HYMENOP.; ICHNEUMONIDAE)
Authors: Walley G. Stuart
Published: January 2010

Female.—Length 7 mm. Head thick antero-posteriorly, the temples scarcely narrowed behind, distinctly broader than eyes viewed dorsally; vertex evenly convex; ocelli small ; ocellocular space fully three times diameter of lateral ocellus; malar space scarcely half basal width of mandible; face distinctly elevated above level of eye-margins, feebly shining with well separated fine punctures, the interspaces finely reticulately sculptured; antennae 23 segmented, first flagellar segment very nearly equal to second and third combined; thorax shining; propleura polished almost without punctures ; mesoscutum with only sparse punctures bearing vestiture ; mesopleura sparsely punctate above and polished impunctate behind, anteriorly and ventrally the punctures becoming more dense toward a patch of very fine dense punctures adjacent epicneimia; metapleura with larger shallow punctures which are somewhat confused by weak rugulae below; propodeum rather elongate, shining, impunctate, dorsally finely and faintly reticulate, median parallel longitudinal carinae very weak, lateral longitudinal carina distinct only on posterior half, apical transverse carina defined laterally but scarcely visible at middle; lateral face of propodeuin a little roughened; nervulus slightly postfurcal, nervellus broken about at middle.
TWO UNRECORDED SPECIES OF SCUTACARIDAE FROM THE SOUTHERN APPALACHIANS
Authors: Jacot Arthur Paul
Published: January 2010

The Scutacaridae are very little understood. Paoli divided the genera chiefly on the basis of presence or absence of ungual hooks on tarsi I and IV. This is patently a superficial and non-phylogenic character. Within a genus all grades of reduction of unguis are to be found so that it is quite conceivable that species without unguis may belong to genera with unguis. Furthermore in each genus one may find, if Paoli's figures are correct, species with dorsal segments, ranging in number from four to six. Yet number of transverse plates, usually regarded as an indication of number of somatic segments, is certainly a more fundamental character than ungual reduction. On the other hand it is quite difficult to determine with certainty the total number of transverse plates in some species. My experience leads me to regard the total number of plates as four, each bearing four bristles. At present this character will have to be disregarded.
CAPITOPHORUS APHIDS INFESTING ARTEMISIA
Authors: Knowlton G. F. , Smith C. F.
Published: January 2010

Approximately 75 species of Artemisia, or sage, occur in the Rocky Mountain region, many of these being infested by aphids, often to a considerable extent. The great economic importance of several specis of Artemisia as food for range livestock and the incomplete knowledge of the aphids attacking them in Utahled the writers to undertake this study. Most of the report deals with the apterous forms which are most frequently encountered and which possess good specific characters for identification.
THE EUROPEAN SPRUCE SAWFLY OUTBREAK IN 1935
Authors: Balch R. E.
Published: January 2010

Serious defoliation of spruce by a sawfly was discovered in the interior of the Gaspe peninsula, P.Q., in the autumn of 1930. The following year an aeroplane survey indicated that some 2,000 square miles of forest was heavily attacked. The species had not previously been recorded from America and was determined as Dipirion polytomum Hartig, which has been known for over 1OO years in parts of Europe but has caused little or no damage there.
SOME EARLY STAGES OF BRENTHIS MONTINUS SCUDDER. (LEPIDOPTERA—NYMPHALIDAE)
Authors: Dos Passos Cyril F.
Published: January 2010

The life history of Brenthis montinus has long been a problem taxing the ingenuity of lepidopterists. Scudder made repeated efforts to secure the egg but never observed a female ovipositing. The egg figured in “The Butterflies of the Eastern United States” (Vol. 3, plate 64 f.38 and plate 67 f.16) was removed from the body of the ♀ (1863 Bost. Journ. Nat. History VII: 626; see also 1874 Geology of New Hampshire 339, 354).
SAY'S GRAIN BUG, CHLOROCHROA SAYI STAL, IN CANADA
Authors: Jacobson L. A.
Published: January 2010

Say's grain bug, Chlorochroa sayi Stal, made its initial appearance in Alberta, in appreciable numbers, during the season of 1935. The history of the recorded damage by this insect is available in the publication by Caffrey and Barber (U. S. D. A. Bul. 779). This publication is the only adequate treatise to date on this pest of economic grains. The first recorded damage was reported by farmers from Gila and Salt River Valleys of Arizona in 1903. Further outbreaks were recorded in the southern states of New Mexico, Arizona, Texas and Colorado, reaching the peak of depredation during the period, 1915 to 1919. Its first occurrence in Montana was noted during the years 1931 and 1932. where it has been causing considerable losses to the farmers in the northern part of that state ever since. Localized outbreaks were reported in Utah during this same period.
THE LIFE HISTORY OF EPHEMERA SIMULANS WALKER IN LAKE WAWASEE
Authors: Speith Herman
Published: January 2010

Ide (1935) has studied the various instars in the development of the nymph of Ephemera simulans Walker, but does not state the length of the life cycle. Neave (1932) decided that in Lake Winnipeg species of Hexagenia, a genus very closely related to Ephemera, took two years to complete the life history cycle. The length of the life cycle and the rate of development of the species of Ephemera have been discussed but never satisfactorily settled. The present paper attempts to answer these questions with respect to Ephemera simulans in Lake Wawasee.
SHORT STUDIES IN THE HISTERIDAE (COLEOP.)— NO. 1

A recent study of the male genitalia of the Lycaenidae of North America, made while the author was attending the University of Colorado, Boulder, Colo., showed several interesting points, especially within the subfamily Lycaeniuae or “Coppers.”
A NEW TEXAS SCARAB (COLEOPTERA)
Authors: Saylor Lawrence W.

In working over my Phyllophaga of the lanceolata-group recently, the present new species was found; although very distinct from lanceolata the following nevertheless resembles it so markedly at a casual glance that it is difficult to pick it out in a series.
A MIGRATION OF THE DRAGONFLY, LIBELLULA QUADRIMACULATA L.
Authors: Bird R. D. , Denning Donald
Published: January 2010

Libellula quadrimaculata L. is a holarctic dragonfly which exhibits gregaricus and migratory behavior. “Immense swarms of this species have been recorded in different parts of Europe cn many occasions” (Tillyard) but such flights have not often been recorded in North America. On June 26 a large flight was observed by R. D. Bird at Brandon, Manitoba in a residential district at the south end of town. The location is thickly planted with Manitoba maple trees which reach a height of thirty to thirty-five feet. To the west and south are severa1 sloughs where the dragonflies might have bred but none of them are within a mile and most of them considerably farther. The day was hot and sultry with a maximum temperature of 85°. A violent thunder storm accompanied by hail passed just to the south in the evening. There was a light west breeze. The flight was first semen at 6.00 p.m.
A NEW ARCTIC BAETID (EPHEMEROPTERA)
Authors: McDunnough J.
Published: January 2010

During the month of August, 1935, Mr. W. J. Brown, who accompanied the Arctic trip of the S. S. Nascopie, was enabled to make insect collections at Lake Harbor, on the south coast of Baffin Island.

The only species of Ephemeroptera obtained were two Baetids which were plentiful in both nymphal and adult state and for which definite associations between nymph and adult were secured.

The one species, which occurred in both sexes, bears so much resemblance to Acentrella lapponica Bngtsson. that I am holding it under this name pending an examination of some of the material by Professor Bengtsson. The second species, a typical Baetis, could only be found in the female sex, nor could Mr. Brown, in spite of diligent searching, discover any imales amlongst the mature nymphs in the brook; it would seem that the species was parthenogenetic, at 1east as far as thecycle emerging in August was concerned. On nymphal characters it falls in the bicaudatus group, with the middle tail reduced to a stub, but can at once be separated by the much larger and relatively narrower type of gill. The following description is offered as the species appears to be undescribed.
AN UNDESCRIBED PEDICULOIDID MITE FROM THE SOUTHERN APPALACHIANS
Authors: Jacot Arthur Paul
Published: January 2010

The Pediculoididae are so strongly sexually dimorphic that there is little resemblance between the sexes, necessitating two sets of keys. As I am particularly interested in the females, they only are here discussed.

In Pediculoides the abdomen tapers posteriad to a blunt point, in all the other genotypes the abdomen is more or less truncate and angular behind. Pygmephorus (often misspelled) has tarsi I swollen and much longer than tibiae I. In Pediculopsis they are subequal. Resinacarus also has large tarsi I. In figure 12 the line around the middle of tarsi I is to be taken as a constriction rather than a segmental boundary. The bristles of legs I are not identical in figures 9 and 12, nor are the bristles of dorsal plates I and III. Resinacarus has three pairs of prothoracic bristles while the type of Pygmephorus has two pairs.
THE ENTOMOLOGY OF PRINCE ALBERT NATIONAL PARK, SASKATCHEWAN
Authors: Cockerell T. D. A.
Published: January 2010

Last September, my wife and I visited the Prince Albert National Park, particularly to see Grey Owl and Anahareo and the beavers at Ajawaan Lake. The country was entirely new to me, and I found very much of interest. Saskatchewan is divided into two very different parts. The southern half has some large lakes, but is essentially a prairie region, where vast quantities of wheat are grown. As we crossed a portion of it travelling from Calgary to Saskatoon, the landscape was monotonous and not very interesting. But the northern half of the province is in complete ccntrast. It is a land of dense forests, with innumerable lakes, large and small. These lakes are warm enough in summer to be the delight of innumerable bathers, but covered with thick ice all winter. This region is in the Canadian zone, whereas the prairie region belongs to the Transition. In the northern (especially north eastern) part of the province is a large area in the Hudsonian zone, sufficiently distinct in aspect to be easily recognised from an aeroplane, I was informed.
MISCELLANEOUS PHYSIOLOGICAL OBSERVATIONS ON THE LABORATORY BREEDING OF FLESH FLIES AND OFMELANOPLUS BIVITTATUSSAY
Authors: Brown A. W. A.
Published: January 2010

The species of flesh-fly under consideration areWohlfahrtia vigilWlk.,Calliphora crythrocephalaMg., andLucilia sericataMg.

Oviposition under laboratory conditions occurred in most cases at night. Under outdoor conditions wild individuals of these species were observed to oviposit only during the day. Lack of disturbance in the cages is suggested as the deciding factor, since temperature and light were kept constant night and day.The site of oviposition preferred is the undersurface of a dry ledge of the meat. On being disturbed the ovipositing female is loth to leave the site.
THE COLEOPTERA OF CANADA'S EASTERN ARCTIC
Authors: Brown W. J.
Published: January 2010

The present paper is an outgrowth of a collecting trip made by myself to the eastern arctic during the summer of 1935. The month of August was spent in the vicinity of Lake Harbour, Baffin Island, and brief stops were made at Port Burwell, Que., at Craig Harbour, Ellesmere Island, and at Pangnirtung and Clyde, Baffin Island. Results were satisfactory, considering the difficulties which the collector must experience in the region, and this success was due largely to indispensable aid received from Major D. L. McKeand of the Lands, Northwest Territories and Yukon Branch, Department of the Interior, and from Mr. James Bell and Mr. Nelson Adams of the Hudson's Bay Company, Lake Harbour.
THE BEES OF ALBERTA—IV

The following is a report on certain specimens of Ichneumonidae found in a small collection of Hymenoptera made by Mr. J. A. Guignard of Ottawa, Ontario, and recently acquired by the writer, for the Canadian National Collection, through the kindness of a relative of the late Mr. Guignard.
NOTES ON CALIFORNIAN EUPHYDRYAS SPECIES (LEPID.: RHOPAEOCERA)
Authors: Doudoroff Michael
Published: January 2010

In the last few years, Lepidopterists have devoted a great deal of interest to the genus Euphydryas. This interest, however, has resulted in a great many valid and invalid names, but in little organization or understanding of specific variation and interrelation. Gunder (Pan Pacific Entomologist, VI, 1-8. 1929), in a carefully prepared and well illustrated paper, made the mistake of lumping all American species under five specific names, which is taxonomically incorrect, regardless of genitalic similarities (Pan-Pacific Entomologist, XI, 144, 1935).
BEES OF ALBERTA. V
Authors: Cockerell T. D. A.
Published: January 2010

Male (type) resembles H. ziziae (Rob.), to which it runs in my table and that of Metz (but in Lovell's table to modestus), differing however as follows: lateral face marks obliquely truncate above, the highest point next to orbit; flagellum considerably longer, pale dusky reddish (instead of bright ferruginous) beneath; tegulae entirely black; base of wings not pale; thorax more robust, light marks on collar separated by an interval greater than the length of one; wings larger, grey, with the stigma and nervures very dark; abdomen shining pure black (compared with an Illinois specimen from Robertson.).
DESCRIPTIONS OF NEW GENERA (LEPIDOPTERA, NOCTUIDAE, CUCULIINAE)
Authors: Franclemont J. G.
Published: January 2010

In the course of revising the subfamily Cuculliinae of the Noctuidae, it has become obvious that many of the species have been placed in genera where they do not belong, and others have been merely “dumped” into the most convenient genus; it is to rectify the above conditions that the following genera are described.

Gertsch of the American Museum of Natural History, and Professor R. V. Chamberlin of the University of Utah.
NOTES ON THE BIOLOGY OF MICROPLECTRON FUSCIPENNIS ZETT. AS A COCOON PARASITE OF DIPRION POLYTOMUM. HARTIG
Authors: Reeks W. A.
Published: January 2010

The results of a three year study of the imported parasites of Diprion polytomum show that an eulophid parasite, Microplectron fuscipennis Zett., gives promise of becoming an important control factor of the spruce sawfly in Canada. M. fuscipennis is widely distributed in Europe, and its habits there have been fully discussed by Morris and Cameron (1935) and by Ullyett (1936).
THE MUSCLES OF THE HEAD STOMODEUM OF AN ODONATE NYMPH, ISCHNURA VERTICALIS
Authors: Grieve Evelyn George
Published: January 2010

The fact that the swallowing muscles have not yet been described for any member of the order Odonata was first brought to the writer's attention in the course of studies on the mechanism of moulting and hatching of I. verticalis. A previous writer on that subject had described an Odonate nymph as swallowing water without the use of any stomodeal dilator muscles, which he had assumed were absent.
DESCRIPTIONS OF EASTERN NORTH AMERICAN SPECIES OF BAETINE MAYFLIES WITH PARTICULAR REFERENCE TO THE NYMPHAL STAGES
Authors: Ide F. P.
Published: January 2010

During the course of investigation of the mayfly fauna in streams in Ontario and Quebec it became apparent that many of the nymphs of the Baetinae are not known although the adults of most have been named. A few nymphs are described in scattered papers in the literature and a key has been made for some Baetis and Pseudocloeon (McDunnough 1932, 1932a) which satisfactorily separates groups within these genera. It would seem that in work on streams in the future these small mayflies would become increasingly important because of their abundance and wide distribution.
A NEW SEASONAL FORM OF COENONYMPHA AMPELOS EDWARDS (LEPID.: SATYRIDAE)
Authors: Field William D.
Published: January 2010

Several years ago the writer received, for determination, several specimens of a species of Coenonympha from Oregon. These specimens turned out to be Coenonympha ampelos Edwards. They were taken in August. Comparing these August specimens with a large series of specimens taken during the latter part of May and early June, I found that the two broods of ampelos were different. The summer brood was slightly lighter in color and much browner, with very little of the dark powdering found on the underside of the secondaries in the spring brood.
NOTES ON THE GENUS CHASMATONOTUS WITH DESCRIPTIONS OF THREE NEW SPECIES (DIPTERA, CHIRONOMIDAE)
Authors: Rempel J. G.
Published: January 2010

This North American genus was erected in 1864 by Loew who based his description on specimens collected in New Hampshire. The species of this genus are readily separated from those of any other chironomid genus by the presence of a median longitudinal fissure on the mesonotum. The nonplumose male antennae are also quite characteristic of this group, although this condition obtains also in the genus Hydrobaenus Fries. At present five species are known, to which are now added three new species.
MYIASIS IN THE FOOT OF A RAT BY WOHLFAHRTIA MEIGENII SCHINER. (DIPTERA, METOPIIDAE)

A NEW THRASSIS SPECIES (SIPHONAPTERA) FROM CALIFORNIA
Authors: Stewart M. A.
Published: January 2010

♂ ♀.—Thrassis desertorum belongs to that section of the genus which is characterized by having metatarsal segment I equaling or slightly exceeding II. In this species metatarsal segment I equals II and III together. The labial palpi exceed the fore-trochantera. The lower genal row consists of 3 bristles ; the upper bristle is located higher than the eye; the middle, and smallest, one is inserted closer to the upper than to the lower genal bristle.
A NEW SPECIES OF THE SUBGENUS KRIBIOXENUS (DIPTERA, CHIRONOMIDAE)
Authors: Rempel J. G.
Published: January 2010

This subgenus has a rather peculiar distribution, one species having been described from equatorial Africa and one from Europe. It is therefore of interest to record a new species from Ithaca, N.Y. The following key will serve to distinguish these species.
THE MALES OF UROCERUS ALBICORNIS F. AND U. FLAVICORNIS F. (HYMENOPTERA: SIRICIDAE)
Authors: Peck O.
Published: January 2010

The females of these two species are markedly different in colour, yet the males resemble each other so closely that Bradley (1913) was unable to distinguish between them. Waterston (is Chrystal, 1928) separated the males by the proportions of the hind metatarsus ; that of U. albicornis F. was “barely five times as long as broad,” while in U. flavicornis F. the metatarsus was “nearly seven times as long as broad.” However, Waterston had but two males of one species, and the metatarsal proportions vary intraspecifically ; on this account, the value of the character cannot be determined without a long series.
MISCELLANEOUS NOTES AND DESCRIPTIONS (COLEOPTERA)
Authors: Fall H. C.
Published: January 2010

In my Southern California List (Cal. Acad. Sci. 1901) a specimen of Agyrtes taken by myself at Pomona was deferred to longulus Lec., our only known species of the genus. Some years later a second example was taken at Pasadena, and more recently specimens from Washington and Vancouver have come to hand. These last agree with LeConte's type from near San Francisco, but the Southern California specimens show certain differences which seem to warrant their being set apart from longulus either as a subspecies or, as I prefer to call them, a distinct species for which I propose the above name.
A NEW MACROMIA FROM BRITISH COLUMBIA (ODON. CORDULIIDAE)
Authors: Walker E. M.
Published: January 2010

While stationed at the Dominion Biological Laboratory at Cultus Lake, B. C., and conducting investigations on the sockeye salmon, Dr. W. E. Ricker spent some of his leisure time in collecting certain groups of aquatic insects and has generously presented the bulk of the material to the Royal Ontario Museum of Zoology. The Odonata, which were kindly sent to the writer, were collected in a most discriminating manner and include some interesting species hitherto unknown to the region. One new species, a Macromia, is described herewith, while the collection as a whole will be reported upon in a future paper.

I employ this subfamily name as used hy Hampson although I believe that in all probability it must be restricted to the genus Acronicta Ochs. and its few close allies, and the term Ampphipyrinae, as used by Seitz in his Macrolepidoptera of the World, employed in its place.
A REVIEW OF SOME RECENT EXPERIMENTAL WORK WITH DERRIS AND PYRETHRUM
Authors: Barrett J. P.
Published: January 2010

During the past three years a great deal of attention has been paid to the use of derris and pyrethrum as basic, non-poisonous insecticidal material. This work was stimulated primarily by the tolerance placed upon arsenicals and other so-called poisonous insecticides. Considerable progress has been made and a number of formulae have been developed for the control of certain insect pests with the use of derris and pyrethrum that give safe, effective and economical kill. New applications are constantly being devised and it is the purpose of this paper to briefly review some of the newer developments in the field of derris and pyrethrum investigations.
A NEW RANCORA FROM THE MOHAVE DESERT (LEPID. NOCTUIDAE)
Authors: McDunnough J.
Published: January 2010

Male. Very similar to serraticoris Lint., but on the whole more contrastingly marked on the forewings, the light purplish-gray color being replaced by a whitish gray, heavily suffused with smoky; t. a. and t. p. lines poorly defined, much as in serraticornis, the former showing the usual sharp angle, outlined by a dark streak, above vein I and the latter in this same area with the usual small dark patch, closely approached to t. a. line and separated from it by a palish area. Rather heavy blackish suffusion in median area along inner margin.
NEW SPECIES OF STONEFLIES (PLECOPTERA)
Authors: Claassen P. W.
Published: January 2010

Herewith are described five new species of North American Plecoptera. Included also is a description of Isoperla petersoni Needham (nec Claassen). Dr. Needham published figures of the nymph and adult of this species, anticipating that I would publish a description of this species before the Utah bulletin appeared in print. In 1931 I described the nymphs of this species as my own. Under the rules of the International Code, however, I believe that this species should now stand as indicated in this paper.
NEW COLEOPTERA FROM WESTERN CANADA VI

Published: January 2010

Length 5-7 mm. Elytra black with margins yellow-brown, prothorax with rather wide margins, brown, disc black with the usual pale apical spots common to the genus. Legs, antennae and ventral surface black. Antennae stout with the usual needle-like appendage to the terminal segment. Prothorax wider than long, the translucent areas irregularly shaped anrl rather large, the disc convex, black, with the central portion not punctate, shining, the margins reflexed as is usual in the genus. The hind angles of the prothorax are narrowly rounded.
NOTES ON THE BIOLOGY OF TWO PANURGINE BEES
Authors: Ainslie C. N.
Published: January 2010

Calliopsis andreniformis is a panurgine bee that inhabits much, if not all, of the eastern area of the United States. It is a small inconspicuous species. The females are about 8 mm. in length, exclusive of antennae, quite robust, general color gray, abdomen fasciate, maculation luteous. The males are more slender, smaller, maculation yellow, face and legs entirely yellow.

I am indebted to the Connecticut Geological and Natural History Survey through Dr. W. E. Britton, its Superintendent, for the facilities which make this study possible. I wish to thank Miss E. B. Bryant of the Museum of Comparative Zoology and Dr. W. J. Gertsch of the American Museum of Natural History for allowing access to material in their respective collections as well as for kind aid and advice.
NOTES ON CERTAIN OF WALSINGHAM'S SPECIES OF OIDAEMATOPHORUS WITH DESCRIPTIONS OF NEW SPECIES (PTEROPHORIDAE)
Authors: McDunnough J.
Published: January 2010

For some time I have doubted whether the existing determinations of certain of Walsingham's species of plumes, based on the revision of this family by Barnes and Lindsey, were correct. Through the kind offices of Messrs. Tams and Stringer of the British Museum of Natural History I have been furnished with drawings of the left claspers of the male genitalia of a number of Walsingham's types in the genus Oidaematophorus; a study of these drawings in connection with my own slide material has confirmed my suspicions and shown that in at least two cases there had been misidentifications by the above-mentioned authors. With a view to clarifying the situation somewhat in this extremely difficult group I offer the following notes.

TUMBLE-BUGS
Authors: Cooper Robert H.
Published: January 2010

“Tumble-bugs” have been interesting to human beings for centuries. As these chubby insects roll their balls across paths, roads, and walks, persons stop to puzzle, and whether country boys, soldiers, golfers, or scientists, all are fascinated by the ball-rolling habit of these creatures.

AN ANNOTATED LIST OF THE INSECT FAUNA OF DOUGLAS FIR (PSEUDOTSUGA MUCRONATA RAFINESQUE) IN THE NORTHERN ROCKY MOUNTAIN REGION
Authors: Bedard W. D.
Published: January 2010

This list is a record of insects which have been found in or on Douglas fir in the northern Rocky Mountain region by personnel of the Forest Insect Field Laboratory at Coeur d'Alene, Idaho. It comprises insects which feed upon the tree, as well as the parasites and associates of these insects. Of the 153 species listed, 102 were collected by the writer while making a study of the Douglas fir beetle (Dendroctonus pseudotsugae Hopk.). The remainder are listed in the laboratory records and were collected by J. C. Evenden, R. E. Balch, H. J. Rust, and D. DeLeon.
A NEW RACE OF EUPHYDRYAS CHALCEDONA DBLDY. & HEW. FROM ARIZONA. (RHOPALOCERA-NYMPHALIDAE)
Authors: Dos Passos Cyril F.
Published: January 2010

For several years correspondents in Arizona and California have been sending out an Euphydryas taken at various localities in Arizona as “hermosa” which is obviously not that species. Hermosa Wright (1905, Butts. West Coast, p. 157, No. 179) was described from southern Arizona which may account in part for the misidentification. It is figured by the author (Plate XIX figs. 179, b, c) and does not appear to be rare in collections.
THELYOTOKOUS PARTHENOGENESIS IN CEPHUS CINCTUS NORT. (HYMENOPTERA: CEPHIDAE)
Authors: Farstad C. W.
Published: January 2010

The wheat stem sawfly (Cephus cinctus Nort.) has recently become established as a serious pest of wheat in the Nobleford—Lethbridge area of southern Alberta, the first appreciable damage to wheat occurring in 1934. Each succeeding year the insect has increased and spread rapidly throughout the area, and in many cases crop losses have run as high as 75 to 80 per cent.
NEW BIBIONIDAE FROM BRITISH COLUMBIA

The material here described represents three new species and one new variety. These were received by the writer from J. K. Jacob of the University of British Columbia and from D. Denning of the University of Minnesota.
WIND DRIFT AND DISSEMINATION OF INSECTS
Authors: Felt E. P.
Published: January 2010

It is over a decade since the writer made a critical examination of literature in relation to the aerial movements of insects (See N. Y. State Museum Bulletin 274, P. 59-129, 1928). Subsequent data has tended to confirm rather than to weaken the conclusions incident to that study.
MISCELLANEOUS LEAFHOPPERS WITH DESCRIPTIONS OF FIVE NEW SPECIES (HOMOPTERA CICADELLIDAE)

Resembling Sanctanus sanctus (Say) but with the vertex blunter, the male styles with apical third with parallel sides, apices truncate and quite deep notch on outer margin. Length 5-5.75 mm.
NEW SPECIES OF NORTH AMERICAN EPHRMEROPTERA WITH CRITICAL NOTES
Authors: McDunnough J.
Published: January 2010

In the present paper, besides descriptions of a few species which appear to be undescribed, I offer some critical notes on certain statements made and conclusions arrived at by Dr. Jay Traver in the taxonomic portion of Needham's Biology of Mayflies. The proof of the pudding is in the eating, and the value of a work such as the above can only be ascertained by constant checking of the keys and descriptions in connection with the examination of typical or topotypical material.
SOME APPARENTLY NEW TEXAN EUPITHECIAS
Authors: McDunnough J.
Published: January 2010

In working over considerable Eupitheciid material collected a number of years ago by the late O. C. Poling in south-western Texas (Jeff Davis Co.,) I have come across several species which appear to be undescribed. I realize that there is always a certain amount of danger in determining as new any species in this genus until such time as the genital characters of all described species in both sexes have been definitely determined.
A NEW RACE OP INCISALIA NIPHON HBN. WITH NOTES ON STRYMON ACADICA EDW. (LEPID. LYCAENIDAE)
Authors: Freeman T. N.
Published: January 2010

Dr. Austin H. Clark recently drew the attention of Dr. McDunnough to the fact that specimens of Incisalia niphon from Canada differ in several respects from niphon as it occurs in Florida (type locality) and other southern localities. Dr. Clark has kindly furnished a female specimen of niphon, taken at Mt. Vernon, Va., which upon study I have found to agree quite well with typical niphon as figured by Hubner in the Zutrage Exot. Schmett. figs. 203 and 204.
PAMMEGISCHIA AND TRICHOFOENUS DISCARDED (AULACOID HYMENOPTERA)
Authors: Townes Henry K.
Published: January 2010

It is strange that such a distinct genus as Aulacus should not have been recognized by American workers, but there seems to be no doubt that our Pammegischia Provancher, 1883 is merely Aulacus Jurine, 1807.
THELYTOKOUS PARTHENOGENESIS IN CEPHUS CINCTUS NORT.: A CRITICISM
Authors: Smith Stanley G.
Published: January 2010

I have read with great interest C. W. Farstad's paper (1938) on “Thelyotokous parthenogenesis in Cephus cinctus Nort.,” since it parallels so closely my own problem in Diprion polytomum Hartig. But, whilst agreeing with his final conclusion that there are doubtless two forms of C. cinctus manifesting alternative modes of parthenogenetic reproduction in different regions of the Province of Alberta, I must nevertheless draw attention to certain statements made by this worker which appear, in the light of modern cyto-genetic knowledge, to be highly improbable.
SOME NEW SUBSPECIES OF NORTH AMERICAN LYCAENIDAE (LEPID.)
Authors: Dos Passos Cyril F.
Published: January 2010

Dr. Willis J. Gertsch has called my attention to three undescribed races of North American Lycaenidae contained in his collection of Rhopalocera which was made when he resided in Salt Lake City, Utah and has kindly supplied me with many of the specimens making up the type series.
GRYLLOBLATTA CAMPODEIFORMIS WALKER—A NEW RECORD
Authors: Gregson J. D.
Published: January 2010

A new record for the distribution and environment of Grylloblatta campodeiformis Walker has been established by the recent discovery of this insect in the dry belt of British Columbia at an altitude of 1500 feet. The occurrence of the “ice bug” at this locality is of singular interest. Supposedly an inhabitant of only the coldest regions, such as are found along the margins of glaciers and mountain streams at high altitudes, this discovery shows that Grylloblatta can exist under extremely dry and hot conditions at a relatively low altitude.
THE INSECT COLLECTION OF THE ROYAL ONTARIO MUSEUM OF ZOOLOGY
Authors: Urquhart F. A.
Published: January 2010

The insect collection of the Royal Ontario Museum of Zoology, at present comprising some 250,000 specimens, had its inception in the insect collection of University of Toronto Biological Museum. This collection was started by Professor William Hinks, first Professor of Natural History, when he established a natural history museum in 1853. At that time various collections of insects, mostly confined to exotic material, were donated or purchased.
THE BEES OF ALBERTA VII
Authors: Cockerell T. D. A.
Published: January 2010

Female. Compared with one from Milwaukee, Wis., Sept. 27 (S. Graenicher), it differs thus: the coarsely punctured shining clypeus without a distinct median groove; tegulae very dark brown (instead of clear red) ; stigma and nervures black or almost so; third discoidal cell more produced at end; hair on anterior border of hind tarsi conspicuously yellowish; basal hair-band of second tergite very broad; the abdominal band clear white. Anterior wing 7 mm. long.
ON THE NUMBER OF MOLTS IN LARVAE OF THE FALL WEBWORM, HYPHANTRIA CUNEA DRURY. (LEP. ARCTIIDAE)
Authors: Swain Ralph B.
Published: January 2010

In the mass of literature, dealing with the fall webworm there are few references to the number of larval stadia. Bruner ( I ) states that there are four or five molts in eastern Nebraska. Dyar ( 2 ), who made measurements of the head capsules, found seven stadia. Snodgrass (3) found six larval stadia. He figures the first, second, fifth, and sixth instars.
THE ARMY WORM OUTBREAK IN NOVA SCOTIA IN 1937
Authors: Pickett A. D.
Published: January 2010

During the last few days of July and the first half of August 1937 there occurred what probably has been the worst outbreak of the army worm. Cirphis unipuncta Haw. in this province. The damage was widespread and in many cases severe.
DESCRIPTION OF THE LARVA OF LUDIUS DIVARICATUS LEC.
Authors: Jewett H. H.
Published: January 2010

Ludius divaricatus (Corymbites) was described in 1853 by LeConte. The sexes were described as different species, the female being named Corymbites crassus. Blanchard in 1889 pointed out that crassus was the female of this species. The writer has examined cast skins of larvae from which both males and females developed and found no characteristic difference between them. The genus Ludius contains a large number of species, but only a few larvae have been described or illustrated.
