During July, 1943, a number of wild and cultivated plants in the Blackwell district, near Sarnia, Ontario, were examined for parasitic nematodes. Wild host-plants of the sugar-beet nematode, Heterodera schachtii Schm., recorded in a note in the Canadian Entomologist of October, 1941, were again noted, and one new host record was obtained for this nematode in Canada.

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.

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.

The following is a list of Hemiptera taken at Hudson Heights, Quebec, during the seasons of 1941 and 1942 between June 7 and September 21. Hudson Heights is located on the Ottawa River approximately nine miles west of where that river meets the St. Lawrence River, and approximately 80 miles east of Ottawa.

The following statement concerning dichloro-diphenyl-trichlorethane, or 2, 2-bis (parachlorophenyl)-1,1,1-trichloroethane, more conveniently referred to as DDT, has been prepared in view of the widespread interest among entomologists in this product and in its pest control possibilities. It is based on information obtained from various sources.

The two-striped grasshopper, Melanoplus bivittatus (Say), generally confines its egg laying to ditches, drift soil and crop margins, but during the autumn grasshopper egg survey in southern Saskatchewan in 1942, this species was observed ovipositing in exposed piles of wheat left in the grain fields at harvest time.

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.

The International Commission on Zoological Nomenclature are now engaged in the publication of decisions taken before the outbreak of war in 1939. These decisions have been embodied in Opinions 134-183 and Declarations 10-12. Of these, Opinions 134-155 and the 3 Declarations have already been published or are in the press. The remainder are ready for printing and will be published as soon as funds are available.

Male lappets vivid deep yellow. Dorsal and ventral sides of abdomen deep bright yellow with a narrow black band on the anterior margin of each segment. The appearance of the species is intermediate between eglanterina and hera, differing most conspicuously from these two in wing color. Primaries pale yellow faintly tinged with pink, but much less intense than in eglanterina. Secondaries brilliant yellow.

On August 10, 1943, the Guelph sanitary inspector brought into the Entomological Laboratory at the Ontario Agricultural College an envelope containing six dipterous maggots taken from a baby's mattress. The mother of the infant was very upset, as she had no idea what the “things” crawling out of her baby's mattress were, and was considering taking some action against the furniture company from which she had purchased the mattress only ten days previously.

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.

The discarded paper nests of Polistes wasps make excellent nesting places for other species of aculeate Hymenoptera, especially for those species that work in mud. I have already published accounts of such use of the nests by the wasp, Trypoxylon clavatum and the bee, Osmia lignaria. Both of these species clean out old Polistes cells and use them for their own young. With mud they partition the cell into small rooms, provide each with food and an egg, and finally seal the opening with a plug of mud.

Peach trees throughout the Okanagan are frequently attacked by a borer which has been generally referred to in the past as Sanninoidea exitiosa Say. It is doubtful, however, if specimens of it were ever submitted for authoritative determination prior to 1940.

Differs from typical behrii (as represented by specimens from Mammoth Camp, Mono Co., Calif., and by Holland's figure) in the considerably larger size, the much darker color of the underside and the heavy nature of the black spotting. On both primaries and secondaries the postdiscal row of spots is much more pronounced and on secondaries the submarginal row is very heavy and the spots show a distinct tendency to inward, triangular elongation.

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.

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.
