The number of new records noted in the Canadian Insect Pest Survey in 1952 was somewhat larger than usual and these and others are brought totether for convenient reference in this paper. Canadian sources of information include Survey reports submitted by officers of the Entomology and Forest Biology divisions, provincial entomologists, and other co-operators; The Canadian Insect Pest Review; Annual Report of the Entomological Sociery of Ontario; The Canadian Entomologist; Annales de l'Acfas; and Proceedings of the Entomological Society of British Columbia. A reference to the collection of the leafhopper Erythroneura flammigera (Geoffr.) on cherry in British Columbia was noted in Science News Letter, a United States publication, and details of the occurrence were obtained from H. H. Ross of the Illinois Natural History Survey.
