NOTES ON HETEROPOGON VESPOIDES BIGOT AND OTHER ASILIDAE
Authors: Burdick W. N.
Published: January 2010

Heteropogon vespoides was described in 1878 by Bigot from a single male specimen. The rather indefinite type-locality was given merely as California, as was often the practice in those days. The description was written in French, Bigot's native language. However, an excellent translation was made by Back (Trans. Amer. Ent. Soc. 35:329, 1909) who appended thereto a note to the effect that he did not believe that this species was known to recent collectors.
A THIRD TENT CATERPILLAR IN EASTERN CANADA (LEPIDOPTERA, LASIOCAMPIDAE)
Authors: Atwood C. E.
Published: January 2010

Everyone who travels the forests or roads of Ontario and the provinces east of it must be familiar with the tent caterpillars of the genus Malacosoma. The best known of these is the orchard, eastern, or American tent caterpillar, Malacosoma americana Fab., which makes its large grey “tents” on chokecherry, apple, hawthorn, wild plum and other trees and shrubs, chiefly of the family Rosacea.
THE JACK PINE BUDWORM AND THE SPRUCE BUDWORM, CACOECIA FUMIFERANA CLEM. (TORTRICIDAE)
Authors: Brown A. W. A. , MacKay Margaret R.
Published: January 2010

During the past decade a severe outbreak of budworm has been in progress on jack pine in northwestern Ontario, following similar infestations in Michigan and Minnesota. It has been observed that budworm on jack pine does not spread to adjacent stands of balsam fir and spruce, and similarly that outbreaks on fir and spruce do not spread to adjacent jack pine stands.
NOTES AND DESCRIPTIONS OF NORTH AMERICAN GEOMETRIDAE (LEPIDOPTERA)
Authors: McDunnough J.
Published: January 2010

The name nubilata Pack. which has been generally applied to the species with black hair-pencil at base of primaries on underside and which was figured in the Barnes & McDunnough “Contributions”, will have to be dropped as a homonym. It is preoccupied by C. nubilata Pack., 1867, Proc. Bost. Soc. Nat. Hist., XI, 48, proposed for a Labrador species; this name was later sunk by Moeschler (1870, Stett. Ent. Zt., 368), as a synonym of his lugubrata, an action concurred in by Packard (Mon. Geom., 118) who, however, wrongly transferred the name to another species in a varietal sense.
THE CONTROL OF PEDICULOSIS AND SCABIES BY MEANS OF PREPARATIONS CONTAINING PYRETHRINS, ROTENONE, AND ALIPHATIC THIOCYANATES
Authors: Twinn C. R. , MacNay C. G.
Published: January 2010

The problem of controlling human lice and scabies is a serious one, especially under war conditions. During the World War or 1914-1918, lice and louse-borne diseases and the skin infection caused by sarcoptic mites were the source of large numbers of casualties arnnng the belligerents. Since that time several insecticides have been developed which show promise of being valuable pediculicides and acaricides.
HADENINE NOTES AND DESCRIPTIONS (PHALAENIDAE, LEIPIDOPTERA)
Authors: McDunnough J.
Published: January 2010

Scotogramma nevada B. & McD. Basing my identification of this species on a male from Bishop, Inyo Co., Calif. which matches the figure of type in the ‘Contributions’ very closely, I find that the genitalia are practically identical with those of ptilodonta Grt., also figured in the ‘Contributions’ Vol. II (1) Pl. IV, fig. 14; nevada should be removed from its present association and placed as a race of ptilodonta, differing in the paler, more gray-tinted color of the primaries with rather better defined maculation.
NEW SPECIES OF PARASYNTORMON FROM THE UNITED STATES (DIPTERA, DOLICHOPODIDAE)
Authors: Harmston F. C. , Knowlton G. F.
Published: January 2010

The four species of flies here described as new belong in the genus Parasyntormon as established by Wheeler in 1899. Curran and Becker, among the more recent writers, have pointed out the very close relationship of Parasyntormon to Syntromon Loew, the latter writer having united the two genera under the name Syntormon.
FAUNISTIC NOTES ON THE DIURNAL LEPIDOPTERA OF THE BIG BEND REGION OF TRANS-PECOS, TEXAS, WITH THE DESCRIPTION OF A NEW MELITAEA
Authors: Tinkham E. R.
Published: January 2010

This is one of a series of papers on the insect life of the Big Bend Region of Trans-Pecos, Texas, in which the author plans to present a fairly complete picture of the insect and animal life of that little known region. The area is composed of Presidio and Jeff Davis Counties, the former mainly Lower Sonoran in its faunal affinities, the latter principally Upper Sonoran and partly Transitional. Each county has its own mountain system; Presidio County the Chinati Mountains and Jeff Davis County the Davis Range. The Chinatis are desert mountains; the Davis are forested with oaks and pines.
COLOUR CHANGES IN MANTIS RELIGIOSA L.
Authors: James H. G.
Published: January 2010

The literature contains many references to the close resemblance of various Orthoptera to the colour of the vegetation and soil on which they occur. Hancock (1911) noted this particularly with the acridid Dissosteira carolina (Linn.) and attempted to determine whether this species changes colour at the critical stage of the last moult. From his experiments he concluded that the Carolina locust does not change abruptly from one colour to another during the critical period following ecdysis, but that the change takes place gradually.
THE OCCURRENCE OF TWO MALE FORMS, DICHOPTIC AND HOLOPTIC, INSIMULIUM EXIGUUMROUBAUD (DIPTERA, SIMULIIDAE)
Authors: Dampf Alfons
Published: January 2010

Every student of entomology is familiar with the remarkable sexual dimorphism displayed by simuliid flies. There are not only striking differences in the coloration of the sexes, but also numerous morphological ones, as the different shape of the thorax, the different form of the claws, of the mouth organs, and especially of the eyes, which, dichoptic in the female, are holoptic in the male and are here sharply divided into an upper part with large facets and a lower strongly pigmented part with small ones.
ECONOMIC IMPORTANCE AND HOST RELATIONSHIP OF PELECINUS POLYTURATOR DRURY
Authors: Hammond G. H.
Published: January 2010

The odd-appearing female of Pelecinus polyturator Dru. is a moderately common insect, generally recognized as a parasite of Phyllophaga larvae. However, few references in literature substantiate the host relationship or furnish evidence to associate parasite with host.
SYNONYMICAL NOTES ON THE PSENINE WASPS (HYMENOPTERA, SPHECIDAE)

In the course of reviewing the Psenine wasps, it has become apparent that the names of several Nearctic species are homonyms or incorrect. These are discussed briefly and renamed below.
AN ANNOTATED LIST OF THE ODONATA OF MAINE
Authors: Borror Donald J.
Published: January 2010

The first records of Odonata from Maine are given by Hagen (1861), who mentioned five species as occurring in the state. In a few later papers (Hagen, 1873, 1874, and 1875, and Walsh, 1863) additional species were recorded from Maine, bringing the total to 27 in 1875.
NOTES ON SOME NORTHERN CANADIAN SIPHONAPTERA, WITH THE DESCRIPTION OF A NEW SPECIES
Authors: Holland George P.
Published: January 2010

The following Canadian records of fleas occurring north of the 60th parallel have resulted from a recent study by the writer of the Siphonaptera contained in the Canadian National Collection at Ottawa. Most of the material dealt with here was collected by C. H. D. Clarke of the Bureau of Northwest Territories and Yukon Affairs, or by various officers of the Royal Canadian Mounted Police during the survey of the Thelon Game Sanctuary.

A REVISION OF THE GENUS CHLOROSEA PACK., WITH DESCRIPTIONS OF NEW SPECIES (LEPIDOPTERA, GEOMETRIDAE)
Authors: Sperry John L.
Published: January 2010

Two years ago, while collecting original descriptions of the geometrid moths, the author stumbled on an apparent discrepancy in Packard's original description of Chlorosea nevadaria (Proc. Bost. Soc. Nat. Hist., 16:31, 1874), and in the later description of the same species in his Monograph (p. 378, 1876).
SOME NEW AND POORLY KNOWN SPECIES OF COLEOPTERA, II
Authors: Brown W. J.

THE PALPATA GROUP OF THE GENUS EUPITHECIA WITH NOTES AND DESCRIPTIONS (LEPIDOPTERA, GEOMETRIDAE)
Authors: McDunnough J.
Published: January 2010

A small group of Eupithecia species, of which palpata Pack, is probably the best known to eastern American workers, forms a compact entity, almost worthy of at least subgeneric designation. In all the species the palpi are very long and porrect, compressed laterally, presenting in consequence a blade-like appearance. In the male genitalia the uncus terminates in a single fine point, in contradistinction to the dorso-ventral bifid nature of this organ in the majority of Eupithecia species.
THE FEEDING HABITS OF YOUNG SPRUCE BUDWORM LARVAE
Authors: Atwood C. E.
Published: January 2010

The spruce budwormCacoecia fumiferanaClem. is a tortricid moth which periodically appears in vast numbers in the spruce-balsam forests of Canada and the northern United States. When these outbreaks occur, the balsam fir is often killed over areas totalling thousands of square miles. Therefore, this insect has conle to be regarded as one of the most serious enemies of pulpwood forests and has attracted a good deal of attention from forest entomologists.
THREE NEW SPECIES OF NEARCTIC DERONECTES (COLEOPTERA, DYTISCIDAE)
Authors: Leech Hugh B.
Published: January 2010

A large, finely punctate, vittate species having the facies of a giant form of D. griseostriatus (Degeer), and to a lesser degree resembling very large specimens of Hygrotus unguacularis (Crotch). Readily distinguished from the described Nearctic Deronectes by the narrowly separated and nearly parallel metacoxal lines.
AMPHOROPHORA STUDIES
Authors: Knowlton G. F. , Allen M. W.
Published: January 2010

A number of species have been described as new from the West since the publication of Mason's revision of the genus Amphorophora (Proc. U. S. Nat. Mus. 67: 1-92, 1925). To make clear the characters and relationships of some of these aphid species, and particularly those which infest berry crops, the present key has been prepared.

Authors: Prince F. M.
Published: January 2010

In the course of investigating the distribution of plague in the western part of the United States, the field units of the U. S. Public Health Service have collected several species of the genera Dactylopsylla and Foxella. Among these collections there are three new species of Dactylopsylla and one new sub-species of Foxella whose characteristics are as follows:

Dactylopsylla neomexicana n. sp.

This species is close to Dactylopsylla bluei (C. Fox).
THE GENUS GIRSCHNERIA TOWNSEND (DIPTERA, TACHINIDAE)
Authors: Brooks A. R.
Published: January 2010

In 1885 von Ernst Girschner described a remarkable Carcelia-like fly from the Thuringian district of central Germany which was noteworthy in that it possessed a number of paired plumose hairs on the head. The facial hairs were the more noticeable as they originate not on the facialia or parafacialia as normal bristles, but apparently in the ptilinal groove between the two regions, two pairs being found here and three pairs on the anterior part of the front.
NOTES ON SOME SKIPPERS, WITH NEW RECORDS FOR THE UNITED STATES (Lepidoptera, Hesperiidae)
Authors: Freeman H. A.
Published: January 2010

Urbanus doryssus (Swains.)

A fresh specimen of this species was observed feeding on papaya blossoms, X-28-44, at Pharr, Texas, by the writer. Two ♂ ♂ were eventually collected near the same spot by the writer, one III-10-45 and the other III-II-45. These two specimens are the first and only ones collected in the United States.
FURTHER DATA ON THE VALUE OF HAND CONTROL OF THE TENT CATERPILLAR, MALACOSOMA AMERICANA FABR. (LEPIDOPTERA, LASIOCAMPIDAE)
Authors: Sweetman Harvey L.
Published: January 2010

The use of mechanical methods in control of the eastern tent caterpillar was emphasized in an earlier paper (Sweetman, 1940). That report which covered the five-year period 1936-1940 is now brought up through the season of 1945. The site has changed little since 1940 except for the annual increment of plant growth. The wild cherries are more numerous, and the older trees are much taller. The variation in abundance of tents each year follows that of the surrounding area showing that migration into the grounds occurs continually.

The atmosphere as a distribution medium for insects has been the subject of extensive investigations, through trapping by kite and by aircraft. It has been found that insects are present at heights in excess of four kilometers, where the temperature is at freezing or below.
NOTES ON THE OCCURRENCE OF THE COMSTOCK MEALYBUG, PSEUDOCOCCUS COMSTOCKI (KUW.), AT NIAGARA FALLS, ONTARIO
Authors: Sheppard R. W.
Published: January 2010

Heavy infestations of mealybug, first noticed on some large catalpa trees in Queen Victoria Park, Niagara Falls, about mid-September, 1944, and watched at intervals from then on, were found through the medium of specimens submitted by Dr. Harold Morrison, U.S. Bureau of Entomology, to be referable to the species Pseudococcus comstocki (Kuw.).
A NEW CANADIAN TABANUS (DIPTERA, TABANIDAE)
Authors: Brooks A. R.
Published: January 2010

The species described below has been standing in the collection under the name Tabanus cinctus F. for a number of years, and only after the capture of a number of the true cinctus (Blanche, Que., July 18, 1941, and Marmora, Ont., 14. VII. 1942) was the error recognized.
STUDIES IN THE CANTHARIDAE, II (COLEOPTERA)
Authors: Fender Kenneth
Published: January 2010

In 1866, Dr. J. L. LeConte described Podabrus fayi and Podabrus protensus. He compared P. fayi and Podabrus tomentosus (Say) noting the differences but failing to indicate any similarity to P. protensus. P. fayi was cited as having black elytra whereas P. protensus was described as having a long tapering neck and with the elytra blackish with the basal fifth and the outer margin as far as the middle reddish yellow, the two colors shading imperceptibly together.
CONDITIONS GOVERNING THE DISTRIBUTION OF INSECTS IN THE FREE ATMOSPHERE: PART III THERMAL CONVECTION.
Authors: Wellington W. G.
Published: January 2010

Atmospheric convection is a process which involves the more or less vertical motion of air currents. During the discussion of winds (Part II), the writer indicated that winged insects inactivated by low temperatures, or wingless insects within any temperature zone, required vertical currents for support, and for assistance in horizontal transport, rather than horizontal currents alone, regardless of the strength of the latter currents. In the following pages, the process known as thermal convection will be considered as a means for the vertical and horizontal distribution of insects.
NEW COLEOPHORIDAE (LEPIDOPTERA)
Authors: McDunnough J.

The following new species were bred in the course of Insect Faunal Survey work carried on in various parts of Ontario.

Coleophora salicivorella n. sp.

Palpi deep smoky, pale whitish inwardly and narrowly along ventral edge of secon joint: ventro-apical tuft on second joint well developed. Antennae with the basal joint deep smoky and slightly tufted, otherwise whitish, annulate with brown.
NOTES ON SOME SPECIES OF CANTHON AND DICHELONYX (COLEOPTERA, SCARABAEIDAE)
Authors: Brown W. J.
Published: January 2010

This species is very common in Oklahoma and apparently in Texas. It restricts itself to areas of virtually pure sand where it replaces Canthon laevis laevis (Drury). It is very similar to laevis, the types of which came from New York and Maryland. Our New York and Pennsylvanian specimens of laevis are distinctly coppery over the entire dorsal surface and have the granules of the dorsum relatively close. Specimens from Illinois, Kansas, Oklahoma, and Alberta are similar and are typical laevis in every respect. Specimens from South Carolina and Florida show no coppery luster.

NOTES ON THE ERICOIDES-DUPLICIS GROUP OF THE GENUS COLEOPHORA (LEPIDOPTERA, COLEOPHORIDAE)
Authors: McDunnough J.
Published: January 2010

Since the appearance of Dr. Braun's article and my own paper dealing with the species of this complicated group of Aster- and Solidago-feeders in which the forewing maculation is more or less similar, I have paid particular attention in field work, especially in the Maritime Provinces, to securing long series of specimens and, whenever possible, males and females in coitu. In consequence I have had before me for study several hundred specimens and have made large numbers of genitalic slides of both sexes with the especial idea of trying to discover adequate characters in these organs whereby the females of the individual species may be separated.
NEW NEARCTIC CRANE-FLIES (TIPULIDAE, DIPTERA): PART XXVII
Authors: Alexander Charles P.
Published: January 2010

The preceding part under this title was published in 1945 (Can. Ent., 77:204-208). The species discussed at this time are chiefly from Oregon, where they were collected by my friends, Dr. James A. Macnab and Mr. Kenneth M. Fender, to whom I am indebted for the privilege of retaining the type materials. Dr. Macnab and Mr. Fender are engaged in detailed studies of this most interesting part of the Coast range and already have added vastly to our previous knowledge in many groups of insects.
OBSERVATIONS ON THE EMERGENCE OF MACROCENTRUS GIFUENSIS ASHM. (HYMENOPTERA, BRACONIDAE)
Authors: Wishart Geo.
Published: January 2010

Macrocentrus gifuensis Ashm. a braconid of the subfamily Macrocentrinae is a parasite of the European corn borer, Pyrausta nubilalis Hubn., in both Europe and the Orient. It was introduced into America as a possible agent in the biological control of this pest. It has been bred in the laboratory for release by the author over an extended period, during which time comprehensive data on its life history have been accumulated (Wishart, 1946). Eggs are laid in the immature corn borer larvae and their polyembryonic development has been adequately described by Parker (1931).
A REVISION OF THE NORTH AMERICAN SPECIES OF LESCHENAULTIA SENS. LAT. (DIPTERA, LARVAEVORIDAE)

Published: January 2010

This paper is a revision of the North American species of the genera Leschenaultia Robineau-Desvoidy, Parachaeta Coquillett and Rileymyia Townsend as they occur north of Mexico. Eight species have been recovered from this area and many more occur in Mexico, the West Indies and South America.
MONTREAL BRANCH, ENTOMOLOGICAL SOCIETY OF ONTARIO
Authors: Sheppard A. C.
Published: January 2010

The following reports the activities of the Montreal Branch of the Entomological Society of Ontario for the 73rd year.

Eight meetings were held during the 1945-46 season, six in the Lyman Room, Redpath Museum, McGill University and two in the Entomological Laboratory, University of Montreal. The average number present at the meetings was eleven, a reduction of four when compared with the figure for last year. This falling off in attendance can be accounted for in part, we believe, by the very severe weather experienced on the occasion of three of our meetings.
A MINUTE ON PARAMYRMOSA SAUSSURE (HYMENOPTERA, TIPHIIDAE)
Authors: Pate V. S. L.
Published: January 2010

In his treatment of the Scoliidae in Fedtschenko's Reise in Turkestan, De Saussure divided the genus Myrmosa into two subgenera: Myrmosa sensu stricto, and Paramyrmosa, which he defined as having “the second cubital cell [of the fore wing] trapeziform; one of its sides common with [i. e. broadly sessile on] the radial cell” and by the first abdominal segment being depressed, triangular, funnel-shaped, and not as strongly nodiform as in typical Myrmosu. In this new Paramyrmosa, Saussure includes only his new Transcaspian species, Myrmosa Radoszkowskyi, which thus becomes the genotype by monotypy.
THE GEOGRAPHIC RANGE OF IXODES SORICIS Gregson.

NOTE ON CERTAIN DICHRORAMPHA SPECIES (LEPID., LASPEYRESIINAE)
Authors: McDunnough J.
Published: January 2010

Judging by the genitalic figure (based on an Ottawa male), given by Heinrich in his revision (fig. 276) and by the remarks in the text (p. 12) the species has been — at least partially — misidentified by this author. Clemens' type (selected by Fernald) is a specimen from Baltimore, Md., in the Academy collection at Philadelphia; the specimcn is unfortunately without abdomen but has recently been very carefully examined by Mr. T. N. Freeman who selected a male specimen from Oak Station, Pa. (Marloff) as almost exactly matching this type.
A NEW CHILOPOD GENUS OF THE FAMILY SOGONIDAE
Authors: Chamberlin Ralph V.
Published: January 2010

The new genus described in this paper is based upon a specimen in a collection made by Prof. V. E. Shelford in Southern California. It pertains to the group for which I, some years ago, erected the family Sogonidae, the known representatives of which occur in Mexico and adjoining parts of the United States. The new genus may be placed among those previously known by means of the following key.
THE INTRODUCTION OF INSECT PARASITES OF THE SPRUCE BUDWORM, ARCHIPS FUMIFERANA CLEM., INTO EASTERN CANADA
Authors: Wilkes A.
Published: January 2010

The extent and intensity of the present infestation of the spruce budworm, Archips fumiferana Clem., in eastern Canada has become a problem of immense national concern (I). The necessity for further knowledge in formulating adequate control programmes has emphasized the importance of considering the possible utilization of natural insect parasites. As part of the more conprehensive study of control being carried on by the Federal Division of Entomology, the Dominion Parasite Laboratory in cooperation with the Forest Insect Unit instituted a programme of parasite introduction in 1943.
A REVISION OF THE SPECIES OF SYMMERISTA HÜBNER KNOWN TO OCCUR NORTH OF THE MEXICAN BORDER (LEPIDOPTERA, NOTODONTIDAE)
Authors: Franclemont J. G.
Published: January 2010

During the first week of April, 1937, while on a collecting trip in central Florida, the writer found a larva of a notodont on oak; at the time of collecting the larva was referred to Symmerista with some doubt as it was unlike the northern specimens, being darker in color and with less contrast in pattern. This larva pupated at Ithaca and the moth, a normal albifrons female, emerged the end of May. Nothing more was thought of the matter until the writer began a general survey of the genitalia of the Notodontidae, preparing a series of genitalic slides of each American species. It was after discovering that the northeastern species of Symmerista was easily and readily divisble into three species on both male and female genitalia that the larva was thought to have some significance.
ACENTROPUS NIVEUS OLIVIER (LEPIDOPTERA:PYRALIDAE) AT HAMILTON, ONTARIO
Authors: Judd W. W.

NOTES ON THE SEASONAL DEVELOPMENT OF MEDETERA ALDRICHII WHEELER (DIPTERA. DOLICHOPIDAE) AS A PREDATOR OF THE DOUGLAS FIR BARK-BEETLE, DENDROCTONUS PSEUDOTSUGAE HOPKINS (1)
Authors: Hopping George R.
Published: January 2010

In 1935, De Leon published a comprehensive paper on Medetera aldrichii as a predator ol Dendroctonus monticolae Hopk., in western white pine and lodgepole pine in Washington. The following data may prove of value because a different species of bark-beetle is involved and additional information is given. The observations were made in 1941 and 1942 at the Trinity Valley Forest Insect Field Station, 22 miles from Vernon. This locality is 2,100 feet above sea level in a mixed timber stand of western larch, Douglas fir, western red cedar, Engelmann spruce, western hemlock, and western white pine. D. pseudotsugae breeds in Douglas fir, and occasionally in western larch.
THE EFFECT OF WATER LEVELS ON LARCH SAWFLY POPULATIONS
Authors: Lejeune R. R. , Filuk B.
Published: January 2010

Cocoons of the larch sawfly normally spend from nine to ten months in the ground per annum under conditions existing in western Canada. For this reason biotic and abiotic soil factors are of paramount importance in the epidemiology of this insect. Preliminary observations and experiments indicate that ground water is one of the most important of these factors in that it not only affects sawfly development directly but also is significant in regulating sawfly predators and possibly parasites.
FIELD IDENTIFICATION OF POTATO APHIDS
Authors: Dionne Leo A.
Published: January 2010

During the summer of 1947, the potato inspectors (Dominion Division of Plant Protection) working in New Brunswick and Nova Scotia were given a course in potato aphid identification based on the methods presented herewith. In nearly all cases a high degree of accuracy was achieved in a few hours of practice. The purpose of this course was to aid the inspectors in determining the potential number of leaf roll vectors present. This paper is given with the hope that the method may be of value to others similarly interested.
THE INFLUENCE OF SPRAY PROGRAMS ON THE FAUNA OF APPLE ORCHARDS IN NOVA SCOTIA: II. OYSTERSHELL SCALE: Lepidosaphes ulmi (L.)
Authors: Lord F. T.
Published: January 2010

In the first paper of this series (5) the ecologica1 approach to apple orchard insect problems was discussed and it was pointed out that the spray program must be considered as an ecological factor. It is obvious that because of the complex relationships of the plant and animal species in an orchard it is impossible to change the relationships of any single species without, in greatcr or lesser degree, altering the whole community. In some cases the disturbed relationship may show immediately in the repression of one pest and the rise of another, while in other cases the changes are much more obscure and the economic effects nlay not appear for a long time. The cause of these change is that a spray aimed at some particular species also, directly or indirectly, aifects many other species in the orchard environment and thus may be expected to alter the numerical relationship of many predacious and parasitic forms to certain pests or potential pests which are their prey. The oystershell scale, Lepidosaphes ulmi (L.), and the European red mite, Metatetranychus ulmi (Koch) = (Paratetranychus pilosus (C & F)) are examples of species which react quickly to changes in spray treatments owing to the large populations they may build up in a short time and to the rapid increase of their predators and parasites when not hindered by the spray treatments.

For reasons which will be given in a forthcoming taxonomic paper, the spruce budworm, Archips fumiferana (Clem.), is here transferred to the genus Choristoneura Lederer, 1859, Wien Ent. Monatschr., 3:242. Genotype: Tortrix rusticana Treitschke, designated by Fernald, 1908, The genera of the Tortricidae and their types, p. 53. The transfer is made at present in order that this species may be properly referred to in a following paper dealing with its external anatomy.
NEW SPECIES OF EPHEMERELLA FROM ILLINOIS: (Ephemeroptera)
Authors: Burks B. D.
Published: January 2010

This paper presents descriptions of three new species of Ephemeroptera from Illinois, all belonging to the genus Ephemerella. These are forms segregated from material in the Illinois Natural History Survey collection; the types are deposited in that collection. Two of these species are closely related to the genotype, E. excrucians Walsh, and it was thought for some time that one or the other of them would prove to be that species. Study of the lectotype of excrucians showed, however, that both of these species are recognizably distinct from excrucians.

During the summer of 1946 specimens of anobiid beetles were received from G. Stace Smith of Creston, British Columbia, for identification. Mr. Smith believed that the specimens represented a new species and requested that the species be described.

This species resembles the European Xestobium rufovillosum DeGeer so closely that they can only be separated with great difficulty, but the habits of the two species are entirely different.
THE AGROTID GENUS AGROTIPHILA GRT. AND ITS GENOTYPE (LEPIDOPTERA)
Authors: McDunnough J.
Published: January 2010

In 1875 (Ann. Lyc. Nat. Hist. N. Y. XI, 108) Grote erecied the new genus Agrotiphila, based on a male specimen collected by Theo. Mead in Colorado and which he had determined as montana Morr. (1875, Ann. Lyc. Nat. Hist. N. Y. XI, 95). His characterization of the genus is as follows: “All the tibiae are spinose. The shape of the abdomen and habitus is as in Anarta. The eyes are naked, encroached upon by the caputal tegument, ovate, narrowed, fringed with lashes, the thorax is thickly and coarsely haired, without tufts. The maxillae are stout. The antennae are simple, thickly ciliate beneath in the male.” Under the specific heading he notes that “my specimen, numbered 28, agrees very well with Mr. Morrison's description, except that the whitish orbicular is open superiorly, somewhat trianqulate, and that the discall marks beneath and on the hind wings above are illegible.” (The italics are mine).
IMPROVEMENT OF THE SEX-RATIO OF A PARASITE BY SELECTION
Authors: Simmonds F. J.
Published: January 2010

It is a well known fact, noticed by many workers engaged in breeding hymenopterous parasites, that there is a tendency in many bisexual species for the sex-ratio to decrease as the breeding work proceeds over a series of generations. In a number of cases the sex-ratio decreases to an extent where only males are produced, and the stock dies out.
THE COCKROACHES OF THE PROVINCE OF QUEBEC
Authors: Chagnon Gustave
Published: January 2010

For a long time, the order Orthoptera was a loosely interpreted group which has now been restricted to more homogeneous forms. The well known cockroaches which formed the family Blattidae are now considered as a séparate order under the name of Blattaria.

The cockroaches are so well known that there is no need for a detailed description of their morphology. They are easily separated from the other insects by their soft bodies, by their oval and flattened form; the antennae are often longer than the body and are composed of many short segments; the head when at rest, is bent under and almost concealed by the pronotum, so that the mouth projects back to the base of the front legs.
FURTHER NOTES ON THE SUBARCTIC ODONATA OF NORTH AMERICA
Authors: Walker E. M.
Published: January 2010

Since the writer's report on “The Subarctic Odonata of North America” was published, several collections have been received from localities included within the territory covered in that paper, which add materially to our knowledge of the dragonfly fauna of the Hudsonian Zone on this Continent. Most of these collections are from the Northwest Territories but a few are from northern Alberta and Newfoundland.
NEW NEARCTIC CRANE-FLIES (TIPULIDAE, DIPTERA): PART XXVIII.

Published: January 2010

The preceding part under this title was published in 1947 (Can. Ent., 78: 155-159). At this time I am describing four species of the genus Tipula from Arizona and California, the types being preserved in my collection except where indicated to the contrary in the text.
BESSA SELECTA (MEIGEN) (DIPTERA: TACHINIDAE) AS A PARASITE OF GILPINIA HERCYNIAE (HARTIG) (HYMENOPTERA: DIPRIONIDAE)
Authors: Hawboldt L. S.
Published: January 2010

This project arose out of studies of the European spruce sawfly, Gilpinia hercyniae (Htg.), in connection with the Canadian Forest Insect Survey at the Dominion Entomological Laboratories, Fredericton, N.B. Bessa selecta (Mg.) had been observed as a parasite of the larch sawfly, Pristiphora erichsoni (Htg.), but particular interest was aroused in it as a parasite occurring on the European spruce sawfly. The latter host was frequently found to bear the eggs and integumental funnels of B. selecta. The object was to study its biology and effectivness as a possible control factor of the spruce sawfly. However, great difficulty was experienced in rearing the host due to high mortality caused by disease. Hence the original aims were not attained to the entire satisfaction of the author.
TWO NEW SATYRIDS FROM NORTH AMERICA

Published: January 2010

Male Length of primaries (measured from the base of the wing to the apex) 25-26 mm. Genitalia identical with those of Minois meadi meadi. Uppe: surface: the primaries as in typical meadi, with two small dark ocelli ringed with light reddish-yellow; the pupils reduced in the anterior ocelli and lacking in the posterior; the area btween the occclli may be suffused with reddish-yellow. Secondaries as in typical meadi, with a well developed submarginal ocellus between veins Cu1 and Cu2, which may or may not be pupilled with while. Lower surface: primaries similar to M. m. meadi. Secondaries with a well developed submarginal ocelllis between Cu1, and Cu2; additional ocelli may also be present between M1 and 2, and Cu1 and 2A. The ground color is homogeneous dull brown, with darker striae which are more sparsely distributed than in typical meadi, and tend to disappear in the limbal area. The dark transverse bands of meadi have almost completclv disappeared.
THE LIGHT REACTIONS OF THE SPRUCE BUDWORM, CHORISTONEURA FUMIFERANA CLEMENS (LEPIDOPTERA TORTRICIDAE)
Authors: Wellington W. G.
Published: January 2010

This paper deals with the orientation reactions exhibited by larvae and adults of the spruce budworm, Choristoneura fumiferana (Clemens), (12) in response to stimulation by light. The insect is an important pest of the coniferous trees, Abies balsamea Mill, and Picea spp., which compromise the pulpwood stands of the forests of northeastern North America. Hence, at present, it is the subject of many investigations. The work reported here is part of an investigation designed to provide data for the development of studies of the effects of weather and climate upon the spruce budworm.

Published: January 2010

A study of embryological development in grasshopper eggs was made as a part of a general study of the effect of weather on the seasonal development of grasshoppers. The variation in the stage of development in which eggs of Melanoplus bivittatus (Say), Melanoplus mexicanus mexicanus (Sauss.), and Camnula pellucida (Scud.) entered the winters of 1941 to 1947 in different areas of the Prairie Region of Canada is presented in the following paper.
A REVIEW OF THE RHYACOPHILIDAE (TRICHOPTERA)

Published: January 2010

Recent examination of a large number of Rhyacophilidae has resulted in the establishment of some very interesting distributional records as well as the recognition of several new species. New species, descriptions of hitherto unassociated females or little known species, and new distributional records in the Rhyacophila, Glossosoma, Anagapetus, Agapetus, and Atopsyche are discussed in this paper I would like to take this opportunity to thank Dr. L. J. Milne of the University of Vermont for the generous loan of his Rhyacophila holotypes, fourteen of which are figured and briefly described herein. Material from the University of Massachusetts is designated as (Mass.), from the University of Minnesota as (Minn.), from the American Museum of Natural History as (AMNH), from the North Carolina Department of Agriculture as (NC) and from the California Academy of Sciences as (Cal.). Unless designated otherwise types are in the writer's collection at the University of Wyoming.
Insects Collected in the Dundas Marsh, Hamilton, Ontario, 1946-47, with Observations on Their Periods of Emergence
Authors: Judd W. W.
Published: January 2010

During the summer of 1947 n project was initiated with the object of determining the earliest and latest dates of appearance and the period of appearance of maximum numbers of the various species of insects which emerge as adults from the Dundas Marsh, Hamilton, Ontario. Previous to this, during the summer of 1946, observations were made on the occurrence of various insects on the marsh. Such observations were continued during 1947 and are reported herewith.
Spiders of the Nueltin Lake Expedition, Keewatin, 1947
Authors: Bishop Sherman C.
Published: January 2010

The spiders considered here were collected by Dr. Francis Harper during the period from May 31 to December 4, 1947, in the vicinity of Nueltin Lake, Keewatin, Canada while on a trip made under the auspices of the Arctic Institute with support from the Office of Naval Research.

A general account of the area and field notes have been given by Harper (1948, pp. 153-184) and Henry W. Fowler has presented a taxonomic report on the fishes (1948, pp. 141-152).

Eleven species of spiders belonging to five families are represented by mature specimens; and juveniles, not determinable to species, add another family.
Nutritional Studies withBlattella germanica(L.) Reared Under Aseptic Conditions: II. A Chemically Defined Diet
Authors: House Howard L.
Published: January 2010

In nutritional studies the proper evaluation of the results depends upon the manifestations of deficiencies. It is essential, therefore, to control all the factors which enter into the nutritional functions of the organism under study. In order to do this, the intervention of symbiotic organisms should be avoided if possible and diets of known chemical entities should be formulated with the ingredients combined in known quantities. Using the cockroach,Blattella germanica(L.), the first condition can be approached, inasmuch as cockroaches can be made aseptic by freeing them from the fauna and flora of their intestinal tract and of their environment following the method described by House and Patton (1949). In the present study the second difficulty has been overcome by using diets formulated especially for this species, among the most important of which is a chemically defined food consisting of known quantities of amino acids, carbohydrates, vitamins, sterols and minerals.
Fleas in the Collection of the Royal Ontario Museum of Zoology
Authors: Hubbard C. Andresen
Published: January 2010

Early in March of 1948 I was asked by a member of the staff of the Royal Ontario Museum of Zoology, Toronto 5, Canada to identify the fleas in their collection. Never having worked fleas east of the Rocky Mountains or to any extent in British Columbia I suggested that the collection be sent to a Canadian specialist or to Dr. Karl Jordan of the British Museum. I was not in the least displeased, however, when on the first of April a packet containing the collection arrived at my home in Tigard, Oregon.
Differentiation by Small Mammal Predators Between Sound and Empty Cocoons of the European Spruce Sawfly
Authors: Morris R. F.
Published: January 2010

In a preliminary paper on the role of small mammals in the natural control of the European spruce sawfly, Gilpinia hercyniae (Htg.), the writer (7) recorded that shrews have a remarkable ability to select sound cocoons in preference to those which are dead or emptied by parasites. This ability was said to be much less apparent, however, in the rodents. However, various experimental aspects of the project on natural control were not completed. This was due mainly to the severe decimation of the sawfly resulting from the combined attacks of small mammals, disease, and parasites. Since the above statements have elicited some interest, it secms worthwhile to present the data on which they were based. Other aspects of the project, particularly those concerned with the populations of small mammals and their relation to forest site, and with the role of larval Elateridae, will be reported later.
A New Type of Microscope-Slide Cabinet
Authors: Stovell T. H.
Published: January 2010

A general requirement of most biological research laboratories is suitable compact storage space for microscope slides. This is particularly true where space is required for storing deeper preparations such as whole mounts in a horizontal plane with their identification labels in full view. Of the many commercial cabinets now available few appear to be entirely satisfactory. Although some are constructed to hold the slides horizontally, in these the slide holders are in the form of trays with a capacity of not more than one dozen slides and the trays are carried in grooves nne above the other. In others, thin drawers are used in which the slides are laid side bv side on the bottom. In the former, considerable handling is required to expose the labels of the slides. In the latter, slides easily become disarranged, and are exposed to an accumulation of dust; and though considerable space is required, the capacity of the drawers in most cases is limited to less than 100 slides. A cabinet in which a number of desirable features is incorporated has recently been developed at this laboratory, and a description of it constitutes the basis of the present paper.

Authors: Wing M. W.
Published: January 2010

While on a short visit in northern Maine during the summer of 1946, I collected a new and interesting ant of the Microgyna group of the genus Formica. The description follows below:

Formica dirksi sp. nov.

Deälate queen, total length 5.1 mm. Head, maximum width through eyes 1.2 mm., at base of mandibles 0.78 mm., length to anterior border of clypeus 1.3 mm. Thorax, Weber's (1938: 155, footnote) measurement 2.1 mm. General characters of the Microgyna group. Mandibles 7-toothed. Clypeus evenly rounded in front, with uneven surface and carina just barely distinguishable as a line anteriorly, but becoming a low blunt ridge through the mid-region and disappearing posteriorly. Head, excluding mandibles and eyes, somewhat longer than broad; narrower in front than in behind, with posterior corners evenly rounded, posterior border and sides slightly convex. Antennae of medium size, scape slightly stouter apically than basally, bent slightly and gradually in basal half, joints 2 and 3 of funiculus distinctly longer than broad; the apical joints only slightly longer than broad. Frontal area distinct, subtriangular, and about twice as broad at base as high. Frontal carinae diverging posteriorly, about as long as width of frontal area. Eyes black, more or less oval, strongly convex, remote from mandibular insertions and close to posterior corners of head. Ocelli medium-sized, round, white and forming an isosceles triangle with a base, which is situated posteriorly, equal to 0.24 mm. Ratio of base to the shorter sides is 10 to 7.
The Effect of Barometric Pressure Upon Oviposition of the Imported Cabbageworm, Pieris rapae (L.)
Authors: Stephen W. P. , Bird R. D.
Published: January 2010

It is a well known fact that the flight of moths and some other insects is affected by barometric pressure, but it is not well known how this phenomenon affects other insect activity. In a study of the ecology of insects in vegetable gardens at Brandon, Man., in 1948, the relationship of barometric pressure to insect activity was recorded.

It was noted in the field that the imported cabbageworm adults behaved differently under varying weather conditions. During warm, clear days they did little but move about freely and feed, but on days that were overcast, particularly preceding rain, they became active about the plants and appeared to be engaged mainly in egg laying.
A Review of R. C. Treherne's Species of Thysanoptera
Authors: Bailey Stanley F.
Published: January 2010

One of the few Canadian entomologists to study thrips was R. C. Treherne who was one of the group of workers to investigate the pear thrips when it first became an economic pest in North America. In the course of his work he collected and studied thysanoptera. His collection, supplemented by exchanges with other workers, formed the basis for the material now in the Canadian National Collection at Ottawa. The writer is indebted to curators of this collection and particularly T. N. Freeman, for the generous loan of valuable specimens for study, particularly the types of Treherne. The Moulton collection is now deposited at the San Francisco Academy of Science, Golden Gate Park, San Francisco, California. We also wish to thank Dr. E. S. Ross, curator, for the opportunity of studying the types of Taeniothrips tahoei Moulton, Tae. pingreei Moulton, Tae. aureus Moulton, and Frankliniella californica Moulton.
