NOTES ON PSYCHODA

Extract

Mr. A1ex. D. MacGillivray has sent me some Psychodidæ from Ithaca, N.Y., for names.

Psychoda Slossonœ, Will.

One male (June). The wings are clothed with blackish hair, and with two broad irregular white bands. The fringe on the posterior margin is blackish (in superba whitish); the abdomen clothed with white hairs (in superba with black); the legs are paler and with more white hair than in superba; and the white hair on head and thorax is not as long nor as dense asin P. superba. A female (Aug.) which is larger and more thickly clothed with white hair is, perhaps, the same as Williston mentions, and is, I think, the female of this species.
