Several writers (Baker, 1917; Patch, 1917, 1918, 1923) have published descriptions and keys for the aphids of the eastern United States. Many of these aphids are found in the Maritime Provinces of Canada. The only published list of the aphids of the latter area is that of Burnham (1938).
The following is a preliminary list for the Maritime Provinces of the aphids of the genus Aphis; collections have been made in various years since 1934. Notes on the dates of collections, hosts, and localities are given for most of the species.
