The fallowing records represent a supplement to my former publication “Holarctic Elements among the Ichneumoninae of Maine” (Jour. Wash. Acad. Science 43. May, 1953, p. 148-50). They are based mainly on material obtained by the Northern Insect Survey, which is a co-operative project of the Canada Department of Agriculture and the Defence Research Board, Canada Department of National Defence.

The following contribution to our knowledge of the Ichneumoninae of the boreal parts of Canada and of Alaska is based mainly on material obtained by the Northern Insect Survey, which is a co-operative project of the Canada Department of Agriculture and the Defence Research Board, Canada Department of National Defence.The contribution brings forward 12 new species and subspecies 3 of them being represented by both sexes, 9 by the female sex only. Some arctic species already named before or regarded as holarctic elements will be treated in a separate publication.

Entomological Research

The study of the insects of northern Canada has in the past depended mainly on a very small number of collections obtained by the early explorers, by a few individuals concerned with mapping and other scientific investigations, and by missionaries. The work of Kirby (1837), the reports of the Canadian Arctic Expedition (Hewitt, 1922) and the Fifth Thule Expedition (Henriksen, 1937), and a few short papers represent the main contributions of many years.Organized entomological research in northern Canada began in 1947 as a joint project of the Defence Research Board of the Canada Department of National Defence, and the Divisions of Entomology, Botany and Plant Pathology of the Canada Department of Agriculture. The research programme was divided into three major phases:

First Time

The following notes report the occurrence in Nova Scotia ofSthereus ptinoides(Germ.) and indicate the distribution in North America of 35 species introduced there from the Old World. Of the Old World species, ten are reported from America for the first time; previous records of two others are probably erroneous. Two, which were named and described inRhyssemusMuls. andScolytusGeoff. as species native to America, are considered introduced, and new synonymy is proposed for them. Confusion of introduced with native species is noted inStethorusWeise andRhinoncusSchön. The material recorded from Newfoundland was collected in the Northern Insect Survey, which is a co-operative project of the Canada Department of Agriculture and the Defence Research Board, Canada Department of National Defence.

In the Northern Insect Survey, sponsored jointly by the Canada Department of Agriculture and the Department of National Defence, the insect fauna of northern Canada was investigated extensively during the summers of 1947-52. The research work has centred on the biting flies and has consisted in large part of taxonomic studies, as a preliminary to biologica1 investigations. In mosquitoes of the genus Aedes, the difficulty of identifying the adult females, particularly those of the black-legged groups, has made biological studies extremely difficult.

During the year 1950 I enjoyed the opportunity of examining the collections of Odonata made by the Northern Insect Survey, a co-operative project of the Canadian Department of Agriculture and the Canadian Department of National Defence. For this privilege I wish to express my thanks to Dr. G. P. Holland and the members of his sraff in the Systematics Unit of the Division of Entomology, particularly to Dr. T. N. Freeman, co-ordinator of the Survev, and Mr. W. A. Brown for “their kindness in providing laboratory facilities during visits to Ottawa and for shipping material to Toronto.

The following descriptions of new species of black flies are based on material acquired from several sources in the Division of Entomology. The largest collections were made by field parties engaged in the Northern Insect Survey, a project commenced in 1947 and conducted by the Division in co-operation with the National Defence Research Board. Much of the simuliid material accumulated by this survey still remains to he examined and it will be several years before the valuable data on species distribution that it contains can be assembled into a form suitable for publication. Several collections of northern material have also been contributed by officers of the Household and Medical Entomology Unit. The rest of the material is the outcome of rnp own field studies in the Ottawa district, These studies, comnenced in 1949 and still continuing, are on a much smaller scale than the northern work and are designed chiefly to increase my knowledge of the group and to verify or supplement certain aspects of the work done by Twinn (1) in this area.

Chicks from 10 broiler strains were randomly allotted and reared at three farms. At 10 weeks of age a random sample consisting of 60 birds of each strain, with an equal number of each sex, was taken at each farm, slaughtered and market graded. At each farm, an official inspector graded the birds according to the standards of the Canada Department of Agriculture. Each bird was graded for the four grade factors: conformation, fleshing, fat and dressing.The number of birds in each grade class was not independent of farm, sex or strain. The 10 strains, ranked on grade scores, tended to rank in the same order at each farm, although the agreement was better for some grade factors than others, and was better when based on males than on females. On a strain rank basis, the grade scores for any one grade factor were not, in general, indicative of the scores for any other grade factor. Also on a strain rank basis, there was a high positive correlation between breast angle and grade scores for fleshing: body weight was not correlated with grade scores for any of the four grade factors, with the possible exception of conformation in the case of males.
