Extract

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.
