274 THE CANADIAN ENTOMOLOGIST. 



Smaller; less than two millimeters long ; fringe on hind margin rather 



short minuta. 



10. Hind tarsi with black at base and tip; wings banded, with distinct dots 

 at ends of veins, but not two spots on margins beyond mid- 

 dle signata. 



Hind tarsi unmarked (yellowish); dots at ends of veins; wings scarcely 

 banded, no basal black band, nor two spots on margins beyond 

 middle attentat a. 



Hind tarsi uniform dark brown; wings with a basal black band, 

 beyond the middle a black spot on each margin, and one or two 

 apical dots opposita. 



Psychoda cinerea, Banks. — This species is known by its uniform pale 

 appearance and average size. It is common at Washington, D. C, and 

 Falls Church, Va., in June, and occurs at Ithaca, N. Y. 



Psychoda minuta, Banks. — This is our smallest species ; I have seen 

 a specimen from Mesilla, N. Mex. (Cockerell). 



Psychoda attentata, Say. — This species is common at Falls Church, 

 Va., near houses, in June. It also occurs at Ithaca, N. Y. Eaton has 

 decided that one of the common European species (P. sexpunctata, 

 Halid.) is identical with P. attentata. The latter name has the priority. 



Psychoda signata, n. sp. — Head and thorax clothed with white hair, 

 some tufts of gray at bases of wings ; antennae white, about as long 

 as width of wing ; legs white, last few tarsal joints black, and a black ring 

 on base of the first tarsal joint of hind legs; abdomen clothed with white 

 hair. Wings marmorate with pale gray and blackish, rather thinly clothed 

 with hair; a blackish patch near base, another rather before the middle 

 from costa to centre of wing, one on posterior part about behind this one, 

 a long one along the apical costal third of wing, often interrupted by three 

 pale spots, and a few small patches on the apical third of hind margin ; 

 all these spots are blackish, irregular, and of indistinct outline. The 

 fringe on costal margin is largely gray, but with two white patches, and 

 the apex white; on middle of hind margin is a long white portion, the rest 

 of the fringe is blackish; the fringe on the hind margin is about one-third 

 the width of the wing. Length of wing, 2 mm. 



A few specimens taken near Washington, D. C, in May. 



Psychoda opposita, n. sp. — Head and thorax clothed with pale gray 

 hair; antennae thick, gray, longer than width of wing; abdomen clothed 

 with rather short gray hair ; legs brown, none of the tarsi marked with
