Sericosema wilsonensis C. 8; S. Two males which seem to belong to this species according to genitalia were taken on July 8; the species differs from juturnaria in its sinaller size, lack of the strong ruddy tinges on the underside and in the position of the dark line on underside of secondaries which in wilsonensis is nearer the middle of the wing and more evenly rounded. There is a further specimen in the Canadian National Collection from Salmon Arm, B. C., July 18 (A. A. Dennys). The species does not appear to have been previously recorded from British Columbia.
