On plate iv. of the “Fauna Boreali-Americana,” Kirby gives a figure of the ♀ of the above species. In June, 1878, while collecting at the Godbout River, Lower St. Lawrence, I captured two males of this species, both on the same day. While Alypia Langtonii, Couper, were abundant in the same locality, no other specimens of A. MacCullochii were seen.
