SOME ROBBER FLIES AND THEIR PREY
Authors: Rau Phil
Published: January 2010

Proctacanthus brevipennis Wied. [C. T. Green]. Many of these robber flies were seen at Ranken, Missouri, on September 6, 1934. Several pairs were in copulo, and one was feeding upon a grasshopper, Syrbula admirabilis Uhler [A. B. Gurney].
SOME INSECTS INFESTING THE “SELENIUM INDICATOR” VETCHES IN SASKATCHEWAN
Authors: Fox W. B.
Published: January 2010

It is known that selenium is highly toxic to mammals (1, 3) and to some insects (6, 8). Aphids cannot tolerate any appreciable quantities of selenium in host plants (4, 5, 10). A selenium content higher than 5 p.p.m. in cotton plants was reported toxic to cotton stainers (Dysdercus howardi Ballou) and to pink bollworm (Platyedia gossypiella Saund.) (6, 8).
A REVIEW OF THE NORTH AMERICAN SPECIES OF GONIA sens. lat. (DIPTERA, TACHINIDAE)
Authors: Brooks A. R.
Published: January 2010

The present sunmary of Gonia sens. lat. is made necessary because of a large number of undescribcd species recently segregated in the Canadian National Collection and by Dr. H. J. Reinhard. The group covered is the same as that summarized by Tothil (1924) and Morrison (1940), the latter work containing all records of species up until 1940 and with illustrations of the male genitalia of each species. It becomes only necessary then to present descriptions of new species and to fit all species into their proper restricted genera (in Townsend's sense): a key to all described North American species and illustrations of the new species are included.
OBSERVATIONS ON THE CLOVER OR BROWN MITE, BRYOBIA PRAETIOSA KOCH.
Authors: Venables E. P.
Published: January 2010

The clover or brown mite, a common pest of cultivated plants, is frequently mentioned in the literature as occurring on orchard trees as well as on a variety of grasses and herbaceous plants. Its habit of entering dwelling at various seasons has even caused it to be included in he category of household pests.
SYMPETRUM INTERNUM, NEW NAME FOR SYMPETRUM DECISUM AUCT., NEC HAGEN (ODONATA, LIBELLULIDAE)
Authors: Montgomery B. Elwood
Published: January 2010

In the course of an examination of types and other specimens of Odonata in the Hagen Collection, in the preparation of a synonymic list of the Odonata of the Nearctic Region, I found that Diplax decisa Hagen, 1874, is a synonym of Diplax [Sympetrum] obtrusa Hagen, 1867.
THE SPRUCE FOLIAGE WORM AND THE SPRUCE CONE WORM (DIORYCTRIA SPP., LEPIDOPTERA, PYRALIDAE)
Authors: MacKay Margaret R.
Published: January 2010

In the literature on forest entomology there has been considerable confusion regarding the true identity of the two species of Dioryctria feeding on spruce in North America. Superficially the adults of these species resemble each other so closely that the one is easily mistaken for the other. In seasonal history and habits, however, they differ very materially.
A CORRECTION REGARDING THE FEMALE SEX OF COLEOPHORA QUADRUPLEX McD. (LEPIDOPTERA)
Authors: McDunnough J.
Published: January 2010

In my original description of the above species I rather doubtfully associated with the male holotype and paratypes two females, largely on account of similarity of locality data; the genitalia of one of these was figured on Plate III, fig. 6. I now find that this association was incorrect and that the name quadruplex must be restricted to the male sex of the original description.
NEW DESCRIPTIONS OF LARVAE OF FOREST INSECTS, VIII. LARVAE OF THE GENUS MELANOLOPHIA (LEPIDOPTERA, GEOMETRIDAE)
Authors: McGuffin W. C.
Published: January 2010

The insects of the genus Melanolophia are forest insects in Canada, the larvae feeding on both coniferous and deciduous trees. McDunnough, in his bulletin discusses five species, three of which are found in Canada.
MALLOPHAGA OF ALBERTA: A LIST OF SPECIES WITH HOSTS
Authors: Brown J. H. , Wilk A. L.
Published: January 2010

Very little attention has been paid to the occurrence of Mallophaga in western Canada, particularly in Alberta. The reason for this is two-fold. First, the difficulty of obtaining keys to species and, second, the extreme difficulty of collecting specimens. This paper reports the occurrence of thirty-eight species in the province.
THE GENUS DINOCNEMIS BANKS (HYMENOPTERA, POMPILIDAE)
Authors: Bradley J. Chester
Published: January 2010

Malar space wanting; antennae distant from the clypeal border by a little less than the length of the pedicel; scape with erect hair beneath, dense in the males; pronotum with a long dorsal surface, rounding rather abruptly into a pronounced but not deep vertical surface, and with a short horizontal collar, all this much in Calicurgus, but less abrupt; upper surface of hind tibiae not carinate, but with minute elevations at the bases of spines which scarcely exceed the length of the tibial hair, and are absent at the base of the tibiae; head, thorax, propodeum, coxae and abdomen of the males more hairy than in the species of Priocnemis.
A NEW TANAOPS FROM NEW MEXICO, WITH SOME NOTES ON THE GENUS (COLEOPTERA, MELYRIDAE)
Authors: Marshall M. Y.
Published: January 2010

As a result of my description of Tanaops testaceus several years ago (1), a friend of mine, Mr. J. W. Green, of Easton, Penn., has sent me a good series of a species in the same genus, from New Mexico. These specimens apparently represent an undescribed species, which I would like to make known at the present time. So far as I am able to determine, no species of this genus has been heretofore reported from New Mexico.
NEW NEARCTIC CRANE-FLIES (TIPULIDAE, DIPTERA); PART XXI
Authors: Alexander Charles P.
Published: January 2010

In the present report I wish to define five species of crane-flies from California, all belonging to the subgenus Lunatipula Edwards of the major genus Tipula Linnaeus. These specimens were collected by Messrs. T. H. G. Aitken, Mont Cazier, Otto Degener, Anthony Downes, and C. D. Michener, to whom I am greatly indebted for the privilege of retaining the types of the various species. In western North America, the subgenus Lunatipula is represented by a host of species that break up into several well-defined groups of forms.
SOME PLECOPTERA FROM THE FAR NORTH
Authors: Ricker W. E.
Published: January 2010

Through the kindness of Drs. J. McDunnough and O. Peck of the Division of Entomology, Ottawa, the writer recently had the opportunity of examining the Plecoptera of the Canadian National Collection which were taken in the more northern parts of Canada, Alaska and Labrador. An additional number have been examined from the United States National Museum, by courtesy of Dr. E. A. Chapin.
A NEW PSYCHID FROM QUEBEC (LEPIDOPTERA, PSYCHIDAE)
Authors: Freeman T. N.
Published: January 2010

Male. Head, thorax and abdomen black, covered with long silvery-grey, hair-like vestiture; antennae greyish-brown, strongly bipectinate and composed of eighteen joints; fore tibia without epiphysis; wings uniformly smoky, without markings and sparsely covered with short pile; fore wing with area adjacent to outer side of the upper part of the discal cell sunken, causing this to appear as an elongate, obscure discal spot; costal and outer margins of all wings darker; fringes light grey. Expanse: 19 mm.
NOTES ON ZACOTUS MATTHEWSII LeC.
Authors: Hatch Melville H. , Fender Kenneth M.
Published: January 2010

Zacotus matthewsii LeC. (matthewsi auct.) is a rare beetle that lives in damp situations under cover in timbered areas in the Pacific Northwest. LeConte, Ann. Mag. Nat. Hist. (4) IV, 1869, p. 373-374, described it from a unique female from Vancouver Island. Horn, Trans. Ent. Soc. IX, 1881, p. 169, listed it from Washington; Leng, Cat. Col. Am. n. of Mex. 1920, p. 68, listed it from “No. Cal.”; Casey, Mem. Col. IX, 1920, p. 290-291, cited specimens from Moscow in northern Idaho and Clackamas Co. in northwestern Oregon; and Van Dyke, Pan-P. Ent. II, 1925, p. 95, from the Bitter Root Mountains of extreme western Montana.
ADDITIONS AND CORRECTIONS TO THE CHECK LIST OF THE MACROLEPIDOPTERA OF ALBERTA
Authors: Bowman K.
Published: January 2010

In the following list of additions and corrections to my “Annotated Check List of the Macrolepidoptera of Alberta”, published in 1919 by the Alberta Natural History Society, the numbers and names are in accordance with the McDunnough list of 1938, the numbers of the Barnes and McDunnough list of 1917 being given in brackets. Since 1921, seven brief lists of additions and corrections have appeared in the Canadian Entomologist (53: 13-14, 211-212, 55:71-72, 56: 189-191, 60: 117-118, 66: 131-132, 70:260-261).
A REVIEW OF THE NORTH AMERICAN SPECIES OF LINNAEMYA SENS. LAT. (DIPTERA, TACHINIDAE)
Authors: Brooks A. R.
Published: January 2010

The name Linnaemya has been used in America and to a lesser extent in Europe for a collection of rather distinct elements linked together by the following characters:

Large robust forms, 8-15 mm. long; eyes densely haired; antennae large, the third segment truncate at the tip; second aristal segment somewhat elongate; palpi reduced in length, as long as the second antennal segment or reduced to mere papillae; epistoma strongly warped forward, the antennal and oral margin axes about the same length; bend of the fourth vein with a strong appendage, the apical cell open far before the wing tip; abdomen stout, bearing at least one pair of discal bristles on the intermediate segments.
HYDRIOMENA STUDIES II: THE RUBERATA GROUP
Authors: McDunnough J.
Published: January 2010

In a previous paper I discussed the character of the female genitalia of the genus Hydriomena in general and more particularly in connection with the glaucata-crokeri group. In the present paper I offer further notes on certain other species of the genus which I have lumped roughly into the ruberata group. All these species show in the male genitalia a deep excavation between the forks of the uncus; each fork tends to broaden toward its apex which is evenly rounded and not bent downward nor pointed.
SOME NEW NORTH AMERICAN LYCAENIDAE
Authors: Chermock F. H.
Published: January 2010

While I was rearranging my Lycaenidae to conform with the McDunnough List, I found it necessary to check some forms which were not determined. Some of these proved to be new. In this paper, I present descriptions of these new butterflies.
NEW NEARCTIC CRANE-FLIES (TIPULIDAE, DIPTERA), PART XXII
Authors: Alexander Charles P.
Published: January 2010

The preceding part under this general title was published in 1944 (Can. Ent. 76: 166 - 172). At this time I am characterizing some Eriopterine crane-flies from the three Pacific Coast states that were collected and sent to me by Messrs. Otto Degener, James A. Macnab, Axel L. Melander, Herman A. Scullen, and the late Millard C. Van Duzee. Except where indicated to the contrary later in the text, the types of the novelties are retained in my collection through the generosity of the collectors.
OBSERVATIONS ON THE LIFE HISTORY OF APAMEA VELATA WLK
Authors: Dethier V. G.
Published: January 2010

To the best of the writer's knowledge, complete descriptions of the larva of this widespread species do not occur in the literature. The larva, one of the most frequently encountered grass-feeders, may be collected abundantly by sweeping lush grasslands. It is first noticed in numbers early in May. All individuals are small, having hatched from eggs laid by moths which had overwintered as pupae. By the end of May the majority have pupated, and adults appear on the wing in June. From the eggs of these developes a second generation. A third appears in August.
NEW ASILIDAE AND MYDAIDAE (DIPTERA) IN THE SNOW COLLECTION
Authors: Hardy D. Elmo
Published: January 2010

This genus is related to Damalis Fabricius. It is distinguished by having the dorsum of thorax clothed with very dense yellow pile (as in Bombomina); this pile is mostly erect and so dense that the ground color is almost concealed. The species of Damalis are more sparsely haired, with the pile mostly recumbent and not at all concealing the ground color.
NOTES ON CHAMBERS' COLEOPHORID TYPES IN THE MUSEUM OF COMPARATIVE ZOOLOGY, CAMBRIDGE, MASS.
Authors: McDunnough J.
Published: January 2010

On a recent visit to Cambridge I was permitted, through the courtesy of the Museum authorities, to examine the types of Chambers' numerous Coleophorid species deposited in this institution and to make genitalic slides of the material. This study has enabled me to clear up a number of doubts which have existed regarding the identity of certain of the species and, I hope, will put our knowledge of the group on a sounder basis than heretofore.
THE DIMORPHISM IN THE MALE COPULATORY ORGAN OF THE CHRYSOMELID ARTHROCHLAMYS BEBBIANAE BROWN
Authors: Brown W. J.
Published: January 2010

Arthrochlamys bebbianae Brown is a small chrysomelid that occurs rather commonly in the Ottawa District. It is one of a group of species that have been confused under the names Chlamys gibbosa (Fab.) and C. plicata (Fab.). Both its larvae, which are case-bearers, and its adults feed on the leaves and on the epidermis of the new growth of a willow, Salix Bebbiana Sarg. The speries appears to be monophagous, and it tends to occur in diffuse colonies.
THE MOSQUITOES OF THE GREATER WINNIPEG AREA
Authors: McLintock J.
Published: January 2010

This study was an attempt to discover, for the Greater Winnipeg district, what species of mosquitoes occurred, under what conditions, their seasonal distribution, and the relative abundance of each species. The field work and preservation of the material were done by the writer in conjunction with his duties, first as Senior Foreman in 1938 and later, in 1939, as Field Manager of the Winnipeg Anti-Mosquito Campaign.
NEW NEARCTIC CRANE-FLIES (TIPULIDAE, DIPTERA), PART XXIII
Authors: Alexander Charles P.
Published: January 2010

The preceding part under this general title was published in 1945 (Can. Ent., 76:217-222). In the present paper I am describing certain species of unusual interest that were collected and sent to me by Messrs. Aitken, Bohart, Degener, Melander and the late Millard C. Vall Duzee, to all of whom I express my sincere thanks and appreciation for this aid. Except where stated to the contrary in the text, the types of the novelties are preserved in my personal collection.
A SIMPLE METHOD OF MOUNTING APHIDS ON MICROSCOPE SLIDES
Authors: Maltais J. B.
Published: January 2010

All stages or aphids and many forms of soft bodied insects can be successfully preserved whole in nlicroscopical mounts provided the specimens are prepared according to methods based on suitable technique. Leading works on the subject, notably those by Kingsbury and Johannsen (4), Eltringham (1). Lee (5), and Kennedy (3), deal essentially with principles, formulae, and processes applied mostly to histological studies with some reference to entomological technique.
A LABORATORY METHOD FOR DETERMINING THE MINIMUM ACTIVE TEMPERATURES OF INSECTS
Authors: Wellington W. G.
Published: January 2010

It is often important to the successful conclusion of insect field-studies to know the air temperatures which govern insect activities, particularly the minimum temperature at which flight occurs. In the field, this is usually a matter of continued observations on the relative abundance of a species, correlated to some degree with observations on the air temperatures at the times of abundance or of flight.
NEW NORTH AMERICAN EUPITHECIAS I (LEPIDOPTERA, GEOMETRIDAE)
Authors: McDunnough J.
Published: January 2010

In the course of my work on North American Eupithecias a number of species have gradually accumulated which I had, from time, to time, tentatively set aside as probably new but which I did not venture to describe as such until I had secured a better working knowledge of the species already named. Rightly or wrongly I believe I have now attained this desirable position and in consequence offer herewith h descriptions of certain new species together with genitalic figures of both sexes, as far as material is available.
NOTE ON HYPERASPIDIUS FLAVOCEPHALUS BLATCHLEY, WITH DESCRIPTION OF THE FEMALE (COLEOPTERA, COCCINELLIDAE)
Authors: Marshall M. Y.
Published: January 2010

In 1924 Dr. Blatchley described this species (Canad. Ent., 56:167) from a unique male specimen collected near Dunedin, Fla., on March 27, 1918. Up to the present time, the female of the species has remained undescribed and, so far as I have been able to ascertain, no additional specimens of the species have been discovered.
REMARKS ON SOME PACIFIC COAST SPECIES OF TROPISTERNUS (COLEOPTERA: HYDROPHILIDAE)
Authors: Leech Hugh B.
Published: January 2010

Thanks to the generosity of Dr. Armand d'Orchymont, Conservateur of the Royal Museum of Natural History in Brussels, I have recently obtained reprints of certain of his papers published during the occupation of that country by the Germans.
LOW TEMPERATURE FUMIGATION
Authors: Monro H. A. U.
Published: January 2010

In the past, fumigation at temperatures much below 60°F. has not been widely advocated to control insect pests in unheated structures. The objections to such a practice have been based on a number of considerations which will be discussed later. The possibility of estending the schedule of treatments to lower temperatures is obviously of great importance in Canada, where the mean monthly temperatures in most parts of the country lie below 60°F. for 8 or 9 months of the year and where there are three or four months when the range is between 40° and 60°F.
THE EFFECT OF SAY STINKBUG FEEDING ON WHEAT
Authors: Jacobson L. A.
Published: January 2010

Say stinkbug, Chlorochroa sayi Stal, is a comparatively new pest of wheat and other seed crops in Western Canada. In the past ten years it frequently has caused severe damage to wheat in many localized areas.
NEW NEARCTIC CRANE-FLIES (TIPULIDAE, DIPTERA): PART XXVI
Authors: Alexander Charles P.
Published: January 2010

The preceding part under this title was published in 1946 (Can. Ent., 77: 186-191). I am here discussing a number of species from the western United States, chiefly from Oregon and California, where they were collected by my friends, Messrs. T. H. G. Aitken, Mont A. Cazier, Kenneth M. Fender and Lawrence W. Saylor, to whom I am greatly indebted for the privilege of retaining the types in my collection. A few additional species were taken by myself in Arizona and Wyoming.
NORTH AMERICAN SPECIES OF THE GENUS LESTIPHORUS (HYMENOPTERA: SPHECIDAE: GORYTINI)
Authors: Pate V. S. L.
Published: January 2010

Over a century ago in his memoir on Gorytes, Lepeletier proposed Lestiphorus for the reception of Rossi's distinctive European species Crabro bicinctus. However, very few subsequent authors have recognized it as a discrete generic entity. It has generally been regarded as merely a species group or occasionally treated as a subgenus of Gorytes or some related genus. But Lestiphorus, although small, is indubitably entitled to full generic rank.
ON SOME CENTIPEDES FROM GEORGIA
Authors: Chamberlin Ralph V.
Published: January 2010

In a small collection from Georgia sent me for identification by P. W. Fattig of Emory University are representatives of the chilopods listed below. The types of the two new species described are in the author's collection.
A REVISION OF THE NORTH AMERICAN SPECIES OF THE RHODOGYNE COMPLEX (DIPTERA, LARVAEVORIDAE)
Authors: Brooks A. R.
Published: January 2010

This paper is a revision of the North American species belonging to the Rhodogyne complex as they occur north of Mexico. Five genera and twelve species have been recognized from this region.
A NEW CANADIAN SPECIES OF SYNDIPNUS, WITH RECORDS OF OTHER SPECIES (HYMENOPTERA, ICHNEUMONIDAE)
Authors: Walley G. S.
Published: January 2010

This species conforms very well with the generic diagnosis given in my previous paper, except in having the thoracic and abdominal sculpture greatly reduced. In the key to species it traces to ungavae Wly., but differs from that species, as well as from all others included in the key, in having the antennae unusually short, with the flagellar segments fewer in number and considerably stouter than in any of these species. In addition, in phygadeuontoides the thorax is notably elongate, with the mesoscutum strongly flattened, and the legs, especially the femora, are unusually short and stout; these characteristics, in conjunction with the generally black body color, being suggestive of some of the smaller Phygadeuonini.
STARVATION OF THE EARLY INSTARS OF THE PALE WESTERN CUTWORM, AGROTIS ORTHOGONIA MORR., AND ITS USE IN THE CONTROL OF THIS PEST
Authors: Seamans H. L. , Rock P. J. G.
Published: January 2010

Each year since 1911 the pale western cutworm, Agrotis orthogonia Morr., has taken a toll of the grain crops in some part of the Canadian prairies. The extent of the outbreak has varied from small, isolated areas of infestation to gcneral outbreaks covering over 150,000 square miles. Until 1936 the only practical method of controlling this cutworm was the use of definite cultural practices designed to prevent the moths from ovipositing in certain fields during August and early September.
RESULTS FROM AN EXAMINATION OF GEOMETRID TYPES IN THE CAMBRIDGE MUSEUM OF COMPARATIVE ZOOLOGY
Authors: McDunnough J.
Published: January 2010

During a recent visit to the Museum of Comparative Zoology at Cambridge, Mass., undertaken primarily for the purpose of studying Chambers' Coleophorid types, I naturally took advantage of the opportunity to examine the numerous types of Geometridae incorporated from the Packard, Swett and Cassino collections. In consequence I was enabled to clear up a number of points which had been worrying me for some time and in the following notes I offer the main results of such studies.
CONDITIONS GOVERNING THE DISTRIBUTION OF INSECTS IN THE FREE ATMOSPHERE: PART IV DISTRIBUTIVE PROCESS OF ECONOMIC SIGNIFICANCE
Authors: Wellington W. G.
Published: January 2010

The economic entomologist is concerned with the eradication or control of insect infestations, or with the restriction of spread of pest-species. In the course of such work, he is often confronted with the appearance of new infestations in cleared or virgin areas. These infiltrations from other source regions originate, in part, from the gradual extensions of other foci by flights or migratory movements, and, also from the intervention of air currents.
CONDITIONS GOVERNING THE DISTRIBUTION OF INSECTS IN THE FREE ATMOSPHERE
Authors: Wellington W. G.
Published: January 2010

Insect collecting by aircraft (1) has shown that individuals of some species of insects attain heights of four or more kilometers above the earth (6). Upon consideration of the meteorological conditions within this vertical range, it would seem that the normal decrease with height of atmospheric pressure, temperature and humidity would bar flights to altitudes such as those at which specimens have been found. Conversely, certain atmospheric processes might act to carry insects inertly to such altitudes, possibly beyond the supposed limits of insect resistance to the first-named elements.
THE SPECIFIC CHARACTERS AND DISTRIBUTION OF AGABUS VANCOUVERENSIS AND A. HYPOMELAS (COLEOPTERA, DYTISCIDAE)
Authors: Leech Hugh B.
Published: January 2010

In describing Agabus vancouverensis mihi, and in separating it from hypomelas and irregularis Mannerheim (Canad. Ent. 69 (7) : 146-150, four text figs. July, 1937), I did not give a key to the specics, and failed to note certain diagnostic characters. Since then the known distribution of the species has been considerably extended, as reported below.
NEW CANADIAN DIPTERA (TACHINIDAE)
Authors: Brooks A. R.
Published: January 2010

The following descriptions of species and genera are based on specimens in the Canadian National Collection. As many of the species have been reared from harmful hosts by the Canadian Forest Insect Survey, descriptions are offered at this time to allow for accurate naming of these specimens. I am greatly indebted to H. J. Reinhard for the loan of material and his many notes on allied forms.
A STUDY OF THE CARYAEFOLIELLA GROUP OF THE FAMILY COLEOPHORIDAE (LEPIDOPTERA)
Authors: McDunnough J.
Published: January 2010

Until recently I have been applying the name caryaefoliella Clem. to the common species of eastern Ontario, the cases of which are found on hickory (C. glabra and C. cordiformis) and which I mentioned and figured in one of my previous papers (1933, Can. Ent., LXV, 161, Pl. X, figs. 19-21). However in early June, 1944, Mr. T. N. Freeman collected a number of cases on shag-bark hickory (C. ovata) at Pt. Rowan in southern Ontario which produced adults very similar in color and maculation, it is true, to our eastern Ontario species, but differing markedly in male genitalic characters.
THE TACHINID GENERA PSEUDOCHAETA AND PHAENOPSIS IN NORTH AMERICA, (DIPTERA)
Authors: Reinhard H. J.
Published: January 2010

Flies belonging to the genus Pseudochaeta are widely distributed in the United States and southern Canada but the allied genus Phaenopsis has not been recorded hitherto from North America. A recent study of the accumulated material in these genera has brought to light a number of distinct species, which are described below. I am especially indebted to C. F. W. Muesebeck, Dr. R. H. Beamer and A. R. Brooks for the loan of material. Types of the new species are in my collection.

This paper describes all stages of the spruce budworm parasite Apanteles fumiferanae Viereck, including the adult. Illustrations of all stages are presented. A short account of the life history of the host is included.
COLLECTING IN SOUTHERN BRITISH COLUMBIA: FINDING OF THE WATER BEETLE DERONECTES SPENCERI
Authors: Leech H. B.
Published: January 2010

In late June, 1943, Professor G. J. Spencer and Dr. R. H. Hanford accompanied Mr. Ronald Buckell on an entomological trip into the Cariboo district of central-southern British Columbia. They planned to visit the grasshopper outbreak areas beyond the Gang Ranch, and so after driving through Clinton and up onto the Green Timber Plateau they turned west. Taking the Gang Ranch road and then the Dog Creek cut-off, they soon discovered that the preceding rainy weather and Chinook winds had made the road a quagmire. For several hours they bounced and slid from one mud-hole to the next, wading out to shove and swear when the car gave up; and upon occasion it was bogged to the running boards.
BENZENE HEXACHLORIDE (“666”) AS AN ACARICIDE
Authors: Gregson J. D.
Published: January 2010

Preliminary studies of the effectiveness of benzene hexachloride, or more exactly 1, 2, 3, 4, 5, 6–hexachlorocyclohexane, against the paralysis tick, Dermacentor andersononi Stiles, have revealed an acaricide more promising than any hitherto tested by this laboratory.
OCCURRENCE OF THE ELM LEAF BEETLE, GALERUCELLA XANTHOMELAENA (SCHR.), AT ST. CATHARINES, ONTARIO
Authors: Sheppard R. W.
Published: January 2010

In July 11, 1945, in the city of St. Catharines, Ontario, while looking for some elm trees reported by Dutch elm disease scouts as being severely leaf-eaten, I found two white elms (Ulmus americana L.) carrying large numbers of coleopterous larvae which were at once taken to be referable to the elm leaf beetle, Galerucella xanthomelaena (Schr.)
NEW NORTH AMERICAN PHALAENIDAE WITH NOTES (LEPIDOPTERA)
Authors: McDunnough J.
Published: January 2010

Male. Closely allied to difformis Sm., especially to the paler colored forms of this variable species. Antennae strongly serrate and fasciculate as in difformis. Thoracic vestiture rather rough, composed of scales and hair, light smoky gray. Primaries pale smoky, with a slightly grayer tinge than is usually found in difformis. Maculation similar to that of difformis but scarcely as distinct, the crosslines being less contrastingly dark and the spots less distinctly outlined. The main difference occurs in the secondaries which are entirely pearly white with no traces of the postmedian line and subterminal smoky shade found in difformis. Expanse 30 mm.
SOME COLEOPHORIDAE OF EASTERN ONTARIO AND NORTHWESTERN NOVA SCOTIA
Authors: McDunnough J.
Published: January 2010

The spring of 1945 was in general very unfavorable for the majority of Lepidoptera in the Ottawa area, due apparently to the killing frosts and wet weather of the latter half of April and throughout May, following abnormally high temperatures late in March and early April. However Coleophoridae were the exception to this condition and the cases of this group were much more abundant than usual. The continued cold, dry, winter weather, without any of the customary alternating thawing and freezing spells was seemingly very suitable to the hibernating larvae; the early warmth stirred them out of their winter lethargy fully a month sooner than usual and their cases proved a protection against the subsequent cold.
THE SPECIES OF THE TRUNCATA GROUP OF THE GENUS DYSSTROMA (LEPIDOPTERA, GEOMETRIDAE)
Authors: McDunnough J.
Published: January 2010

Since the appearance of the article on the difficult truncata-citrata group of this genus by Swett (1917, Can. Ent., XLIX,, 64) and by Barnes and McDunnough (1917, Contr., III, (4), 227, Pls. XXI, XXX; 1918, Contri., IV, (2), 137) little has been published concerning the North American representatives with the exception of the addition of a couple of new form-names by Wright and Blackmore. In the European literature several important papers, however, dealing with the Palaearctic species of the genus, have appeared; chief among these is the very comprehensive Monograph of the Palaearctic Species by Dr. P. Heydemann (1929, Mitt. Munch. Ent. Gesells., 207-292, Pls. I-XV) copiously illustrated with figures of the adults and of the genitalia, both male and female.
GRACILLARIID STUDIES (GRACILLARIIDAE, LEPIDOPTERA)
Authors: McDunnough J.
Published: January 2010

As a result of breeding carried on in the course of Insect Faunal Survey in the Maritime Provinces, combined with a study of genitalic characters, it has been found that the present application of names, especially in the alnivorella group and the so-called “red-winged forms”, is very faulty. More species, similar in general appearance but easily differrentiated on male genital characters, have been found to occur than has been previously supposed; it is with a view of straightening out the nomenclature that the following notes have been prepared.
COLLECTING IN SOUTHERN BRITISH COLUMBIA: HILLTOP TO LAKESHORE FOR BEETLES
Authors: Leech Hugh B.
Published: January 2010

Beetle collectors are lucky. Weather permitting, they can hunt almost the year through, for many species of Coleoptera hibernate as adults. When snows are deep our treasure houses are old stumps, and dead trees with the bark still on but loose. Better yet are November days when early frosts have sent the lakeshore forms to shelter, and every driftwood log is home to a dozen species.
COLEOPTERA NOTES II: SILPHIDAE
Authors: Arnett Ross H.
Published: January 2010

This is the second of this series (1) of notes discussing certain phases of Coleopterology. The present paper again deals with the family Silphidae and is a continuation of the first. In this note two species are discussed as well as the synonymy of some species of Nicrophorus and notes on the family in general.
NOTES ON THE MENOPONIDAE OF NORTH AMERICA. I.

This is the first of a series of papers dealing with the Menoponidae of North America, in which it is hoped that each genus can be discussed and illustrated. The author wishes to acknowedge the kindness of Dr. G. F. Ferris in lending the Stanford Collection, containing V. L. Kellogg's type material, which is being used in these studies; and of Dr. C. F. Mr. Musebeck, for the loan of material from the United States National Museum.
ACETIC ACID ODOR FROM STENOLOPHUS FIDELIS
Authors: Leech Hugh B.
Published: January 2010

On October 8, I was collecting insects from under stones by a little pond on the Commonage road near Vernon. B. C. Small, shiny, black carabids were common, and several were picked up with tweezers and dropped into a vial of alcohol. Though the day was cold and windy, a smell of acetic acid was noticed and traced to the tweezers. The next carabid taken I incautiously held close to my nose: the odor it emitted choked me and made my eyes smart for a second. Other specimens were tested with due caution, and nearly all produced a puff or spray of acid. The smell was as pungent as ever I have experienced when disturbing a colony of red ants.
NOTES ON THE LIFE HISTORIES OF THREE FLORIDIAN BUTTERFLIES
Authors: Chermock Ralph L. , Chermock Ottilie D.
Published: January 2010

While collecting butterflies in southern Florida, we were successful in rearing many of the native species. In checking through the literature, no data could be found on the early stages of three of these, although d'Almeida and Costa Lima have published some notes on the metamorphosis of the Brazilian subspecies of Appias drusilla. It was thought, therefore, that it might be helpful to other Lepidopterists if we were to note our observations on the life histories of these butterflies.
INTERNATIONAL CONGRESS OF ENTOMOLOGY
Authors: Johannsen O. A.
Published: January 2010

The eighth International Congress of Entomology will be held in Stockholm, Sweden, August 9-15, 1948. The fact that all steamship sailings are currently booked to capacity for months in advance makes it seem necessary for those expecting to attend the congress in 1948 to arrange for passage as early as possible. Steamship companies have not issued sailing lists for 1948, but expect to do so in the early fall. A number of lines have listed sailings for the present season, among them, the Cunard, French, Belgian, Swedish, Norwegian, Gdynia (Polish), Holland-American, etc., the first mentioned expecting soon to have two new steamers in service.
ADDITIONAL NOTES ON COLEOPTERA TAKEN IN ESSEX COUNTY AND SOUTHERN ONTARIO, CANADA.
Authors: Hicks S. D.
Published: January 2010

This list follows closely on the third of three previously published articles in the Canadian Entomologist. Mr. C. A. Frost of Framingham, Massachusetts, has checked and supplied me with identifications of all but two of the specimens. His generous interest in determining some of the beetles for which names have been difficult to obtain made this paper possible.
THE EFFECTS OF A MISCIBLE OIL, A DI-NITROL COMPOUND. AND D.D.T. EMULSION UPON THE EGG MASSES OF THE EASTERN TENT CATERPILLAR MALACOSOMA AMERICANA L.
Authors: Johansson W. I. , Rosene Lois , Warner C. N.
Published: January 2010

In the course ot laboratory tests with insecticides, some interesting data were obtained relative to the effect of certain materials upon the over-wintering egg masses of the Eastern tent caterpillar. The data appear to be of sufficient interest to warrant further study and are presented here with that purpose in mind.

A number of egg masses was collected. These were brought into the laboratory, were examined and sorted into lots roughly comparable in numbers. The twigs to be sprayed were segregated. Solutions of the following insecticides were then prepared.
AN UNUSUAL NESTING SITE FOR THE ANT LASIUS FLAVUS NEARCTICUS WHEELER
Authors: Hicks S. D.
Published: January 2010

On July 30, 1947, what appeared to be the nuptial flight of the above species occurred in the home of a resident of Windsor, Ontario. Hundreds of males and females appeared suddenly from the base of the toilet in the bathroom on the ground floor of the cottage and flew to the open screened window. Dr. William S. Creighton, who identified the species, has remarked that the choice of such a nesting site was certainly unusual for an ant which normally nests outdoors.
A PRELIMINARY TEST OF DDT AND BENZENE HEXACHLORIDE FOR THE CONTROL OF WIREWORMS IN A SASKATCHEWAN POTATO FIELD
Authors: Arnason A. P. , Fox W. B. , Glen R.
Published: January 2010

An inexpensive, simple, chemical control of wireworms in land to be used for vegetable production has long been sought in the Prairie Provinces. Existing methods of control (3, 4, 5, 6) are not wholly satisfactory for row crops. The cultural measures commonly advocated (6) will reduce wireworm infestations sufficiently that cereal crops can be grown without serious damage, but they are not usually sufficiently effective that potatoes or other row crops can be produced successfully. Crude naphthalene is the most satisfactory of the chemical methods recommended (3, 4, 5) but it is too costly for material, is difficult to handle and apply, and is effective only under certain conditions of soil, moisture and temperature. As a result, commercial potato production on the prairies has been restricted largely to districts and fields where wireworms are virtually absent.
PARTICLE SIZE OF DDT WETTABLE POWDERS IN RELATION TO TOXICITY
Authors: Dustan G. G. , Putman W. L.
Published: January 2010

It is generally considered that the smaller the particle size of insecticides applied as solids, the greater is their effectiveness. Smith and Goodhue (1) arrived at his conclusion after a review of the literature. Woodruff and Turner (4) showed that decrease in particle size of DDT wettable powders increased the toxicity of the residues against house flies, and that correspondingly better results were obtained from the residues of smallest particle size in a field test against potato leafhopper and fleabeetles. Steiner et al. (2), who have done much work on the effect of DDT particle size on codling moth control, stated that for this purpose the optimum surface mean particle diameter for DDT lies between 2.5 and 5 microns.
NOTE ON THE DISAPPEARANCE OF DEAD GRASSHOPPERS FROM SITES OF APPLICATION OF CONTROL MEASURES
Authors: Putnam L. G.
Published: January 2010

For some years it has been evident to workers conducting research on grasshopper control methods that those dead grasshoppers which can be found at the scene of application of a control measure do not necessarily represent all the grasshoppers which have succumbed to the treatment. Often, dismembered remains are considerably in evidence and usually only the more resistant parts, such as head capsules, remain to be found. It is reasonable to suppose that many of the dead bodies of grasshoppers may disappear entirely, before sufficient time has elapsed for the final observations on the treatment. It is important, therefore, in relation to the appraisal of the efficiency of control measures in the field, such as baiting, to know to what extent this is true. It is particularly important in the study of baits because, where arsenites are used, at least three days may be required for the poison to take full effect after ingestion and before the appraisal can be made. Meanwhile, a considerable period of time has elapsed during which grasshoppers that died 1 or 2 days after feeding could be removed. Under these circumstances it would obviously be erroneous in appraising the results, to take into consideration only the counts or estimates of numbers of dead on the ground, particularly if compared with the estimated population prior to baiting.
SOME FACTORS INFLUENCING DIAPAUSE
Authors: Simmonds F. J.
Published: January 2010

In a previous paper (Simmonds 1946) a curious factor affecting diapause in insects was recorded. In two species of parasitic Hymenoptera the age of the parent female at the time of oviposition has a marked effect on the tendency of the resulting larva to enter a state of diapause when full-grown. The older the female at the time of oviposition the greater is the chance that an egg will produce a larva entering diapause. In a second paper (Simmonds 1948) this maternal influence on the tendencies of her progeny to enter diapause was investigated further. Some general conclusions were drawn as to the nature of diapause, and the experiments were considered in the light of the various theories put forward to explain the phenomenon. In brief it was concluded that the underlying cause of diapause is the occurrence of a physiological disturbance at some stage in the life-history.
CROW EATING SERICA BEETLES (COLEOPTERA, SCARABAEIDAE)
Authors: Leech Hugh B.
Published: January 2010

On July 6, 1946, Game Warden, J. P. C. Atwood, of Vernon, B. C., saw a number of crows (Corvus brachyrhynchos hesperis) in coniferous trees adjacent to the highway, near where the Monte Creck road meets the Vernon-Kamloops road. He shot one on the wing, killing it in the air. The bird must have landed on its crop, for on reaching it he found its beak held wide open by a mass of beetles which also filled its throat and spilled out onto the ground.
THE INFLUENCE OF AIR CURRENTS ON THE INSECTICIDAL ACTION OF DDT, BENZENE HEXACHLORIDE, HERCULES TOXICANT 3956, AND VELSICOL 1068.
Authors: Dustan G. G. , Armstrong T. , Putman W. L.
Published: January 2010

In March, 1946, the writers reported in Scientific Agriculture (1) that benzene hexachloride showed pronounced fumigant action and that air currents as slow as 2 m.p.h. lowered its effectiveness against insects to a marked extent. The present paper deals with further experiments with benzene hexachloride and gives preliminary data on the fumigant action and effect of air currents on three other chlorinated hydrocarbons, viz., DDT, Hercules Toxicant 3956 (a chlorinated terpene) and Velsicol 1068 (a mixture of isomers with the empirical formul C10 H6 Cl8).
A DIPTEROUS INSECT NEW TO QUEBEC, ACROCERA STEYSKALI SABR.
Authors: Chagnon Gustave
Published: January 2010

I had recently the pleasure of receiving from Mr. J. I. Beaulne of Quebec City an interesting dipterous insect for identification. The locality label attached to the specimen read “Lachine, Que., 4, IX, 43, J. I. Beaulne.” The insect belonged to the genus Acrocera of the family Acroceridae and did not match any of the specimens in the collection of the University of Montreal. I sent it to Mr. G. E. Shewell of the Department of Agriculture, Ottawa, for identification. Mr. Shewell kindly replied, stating that the fly was Acrocern steyskali Sabr., a new record for Quebec. He further stated that the species was described quite recently from northeastern United States material and that he did not think it had been recorded from anywhere in Canada.
A DESCRIPTION OF CAGES USED FOR THE LARGE-SCALE BREEDING OF STURMIA SP., A TACHINID PARASITE OF SAWFLIES
Authors: Coppel H. , House H.
Published: January 2010

In the establishment of insect parasites, the production of large numbers for release in heavily infested areas is often desirable. This was especially true in the case of parasites of the European spruce sawfly, Gilpinia hercyniae Htg. The rapid increase in numbers nad extent of the sawfly infestation in Canada with the resulting losses in timber as reported by Balch (1940) and Baird (1940) created a situation of grave concern, and the need for rapid colonization of insect parasites as part of the general control programme was considered urgent. Of the parasites chosen for introduction, the tachinid Sturmia sp. was considered very promising. Following initial establishment of this species, it was decided that an attempt should be made to propagate it in numbers sufficient for widespread distribution either by improving the methods in use at that time or by devising radically different methods.
FURTHER OBSERVATIONS ON THE CHANGES TAKING PLACE IN THE CORN BORER POPULATION IN WESTERN ONTARIO
Authors: Wishart Geo.
Published: January 2010

The seasonal history of an insect has an important relationship to the success or failure of any efforts to usr parasites in its control. In the work on parasites of thr European corn borer, Pyrausta nubilalis Hubn., over a period of years, the writer has had an opportunity to observe the changes which have taken place in the seasonal history of this insect in Western Ontario. It was shown by the writer (Wislwt, 1942, 1944) that there was a gradual and rather consistent increase in the proportion of the population which had two generations instead of one. The present paper presents further data pertinent to this subject.
NEW NEARCTIC CRANE-FLIES (TIPULIDAE, DTPTERA): PART XXIX
Authors: Alexander Charles P.
Published: January 2010

The preceding part under this general title was published in 1947 (Can Ent., 79: 68-73). At this time I am describing a small series of Eriopterine crane-flies from California, taken chiefly by myself in 1946, with one further species secured by Mr. John L. Sperr. The types of the novelties are preserved in my collection of Tipulidae.
HISTORY OF THE MONTREAL BRANCH OF THE ENTOMOLOGICAL SOCIETY OF ONTARIO

Published: January 2010

The Montreal Branch of the Entomological Society of Ontario, passed its seventy-fifth anniversay on October 16th, but did not hold a special meeting on that date as we had anticipated it at our annual meeting on May 15th and had previously invited the Parent Society to hold their annual meeting in Montreal as a Conunemorative Anniversary Celebration. When our invitation was accepted we were pleased, and we greet you here, and trust you will enjoy meeting with us at the three Institutions that have aided greatly in our pursuit of Entomology, namely, McGill University Université de Montreal and Macdonald College.
AN OUTBREAK OF AEROPEDELLUS CLAVATUS (THOMAS) (ORTHOPTERA, ACRIDIDAE)
Authors: Paul L. C. , Berg V. L.
Published: January 2010

In west-central Saskatchewan at a single location 18 miles southwest of Laporte, Aeropedellus clavotus (Thomas) appeared in outbreak numbers and destroyed 300 acres of crop in 1936.

The outbreak was resrictcd to two adjoining fields each of 300 acres, but the two differed widely in the amount of damage. These fields were adjacent to the South Saskatchewan River, with a mile of prairie extending down to the river on one side and two section of native prairie on the other. The soil at this location is heavy clay, which is typical of the district.
