Extract

Twelve species of sawflies are common on white birch (Betula papyrifera Marsh.) in the forested areas of Manitoba and Saskatchewan. They also occur in Fastern Canada and the United States. A key is presented at the end of the paper by which the late instars of these twelve species can be identified. The immature forms of these species were described by Dyar (1893, 1895a, 1895b, 1895c), Middleton (1915, 1922) and Riley (1890). Unfortunately these descriptions are scattered in several publications, and in most cases the names of the genera or species in the original descriptions have been changed (Ross 1951). This paper brings together the current nomenclature and some biological information on these species.
