An ecological survey of mosquitoes was made at the southern end of James Bay from Moose Factory at the mouth of Moose River to Cochrane, Ontario from 6 to 16 June and 6 to 10 July 1949. The mosquitoes are typical of the subarctic northern transcontinental conifer forest in which this area occurs. Twenty-seven species of culicids have been collected including four species of chaoborines. The larval habitats, vegetation types and observations on the larval habits are presented for each species. The most abundant species were Aedes punctor and A. excrucians. A stalked protozcan and algae were found on the larvae. The dates of occurrence of larvae and adults, and biting records of adults are given. Male swarms of A. communis and A. punctor were observed. Most of the species were reared in the laboratory and individual associations were made of larvae, pupae, and adults for taxonomic studies. Control of the mosquitoes would be difficult due to the extensive area and variable types of habitats in which the larvae occur.
