Psychoda pacifica Kincaid. Ent. News, VIII. 6. 



This species, origiually described from Seattle, seems to range 

 along tbe whole Pacific coast, since representatives have been ex- 

 amined from Alaska. Oregon, eastern "Washington and California, 

 which, although varying in some respects from the type speci- 

 mens, seem to be specifically the same. The Alaska specimens wei-e 

 secured by the writer during the summer of 1S9S at Sitka, Uualaska 

 and the Pribilof Islands in IJering Sea. The variety found upon 

 the Pribilofs differs considerably from the type form. They are on 

 the average ranch smaller than the latter; the antennae are 14- 

 jointed, owing to the absence of one of the small terminal articles, 

 and the inferior appendages of the male genitalia are much more 

 strongly curved towards the lip. The Unalaskan and Sitkan ex- 

 amples resentble the types quite closely, about the only difference 

 being that the wings are more acutely pointed than is usual in the 

 latter. Tbe Oregon specimens were taken at Corvallis, Oregon, 

 during the month of June. 189S, while the Californian examples 

 were included in a collection of Psychodidie sent to the writer 

 through the courtesy of Mr. R. E- Snodgrass from the Leland 

 Stanford Junior University. From Professor Charles V. Piper, of 

 the Washington Agricultui-al College, four specimens of P. pa- 

 cifica were recently obtained, which were collected at Pullman. 

 Washington, the specimens being dated from July 12 to July 27. 

 1898.

This is a Pericoma. The posterior bifurcation is much nearer the 

 base of the wing than is the anterior one: the wing is pointed ex- 

 actly ai the tip of the first simple vein.
