Extract

Among the numerous insects attacking the leaves of birch in North America are Profenusa alumna (MacG.) and Fenusa pusilla (Lep.), both of which are leaf-miners belonging to the tribe Fenusini. Various attempts have been made to separate the known fenusine larvae, all of which are very similar (Yuasa, 1922; Ripper, 1931; Lorenz and Kraus, 1957; Lindquist, 1959), but the larval morphology of F. pusilla only has been described in detail (Friend, 1933; Daviault, 1937). In this paper the larval morphology of P. alumna is described from material collected some 60 miles north of Sault Ste. Marie, Ontario, in 1955.
