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.

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 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:

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 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.

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.

Scale insects (Hemiptera: Sternorrhyncha: Coccomorpha) are obligate plant parasites feeding on plant sap; some are damaging pests in agriculture, horticulture and forestry. Despite their economic importance, the scale insects found in continental Africa have not been extensively studied and the keys for identifying them are incomplete and scattered through the literature in several languages. The aim of this study is to improve our understanding of the African scale insect fauna. As a first step towards their identification, we provide a key to the 23 families currently known from continental Africa, based on slide-mounted adult females, covering Aclerdidae, Asterolecaniidae, Cerococcidae, Coccidae, Conchaspididae, Dactylopiidae, Diaspididae, Eriococcidae, Halimococcidae, Kermesidae, Kerriidae, Kuwaniidae, Lecanodiaspididae, Margarodidae, Matsucoccidae, Micrococcidae, Monophlebidae, Ortheziidae, Phoenicococcidae, Pseudococcidae, Putoidae, Rhizoecidae and Stictococcidae.

Poultry Breeding. Morley A. Jull. Senior Poultry Husbandman. Bureau Animal Industry, U.S. Department of Agriculture. New York: John Willy and Sons, Inc. — London: Chapman and Hall, Limited. 1932.The purpose of this book is to convey to its readers some conception of the manner in which various characters possessed by the domestic fowl are inherited. The discussion of fundamental principles involved should stimulate further research concerning the problems raised. The results of various lines of research work are reviewed and an extensive list of literature references is given, so that the investigator, teacher, and student each has a ready reference for review purpose.
