Psychoda chierea, nov. sp. 



Thorax and abdomen with long gray hair, a tuft of black hair at base 

 of wing ; wings with gray hair and fringe, the latter on the posterior 

 margin nearly three times the width of a cell ; legs pale with long, gray, 

 and short white hair, and black scales on the tarsi. Antennae slender, a 

 little longer than the width of the wing, base of joints blackish, each joint 

 with a whorl of white hairs ; wings about as broad as in P. alternata, 

 acute at tip. The inferior pair of $ appendages is long, contracted in 

 the middle, swollen beyond, then growing slender and curving upwards, 

 clothed beneath with white hair ; the superior pair much shorter and 

 curved downwards near tip, they are quite suddenly swollen near the 

 middle. Ventral plate of $ as broad as long, slightly emarginate behind 

 and with short scales, the ovipositor quite prominent and slightly curved. 

 Length of wing, 2.1 to 2.8 mm. 



Common on windows daring June and July ; Sea Cliff, N. Y. 



This species is readily distinguished from the preceding by its slightly 

 darker colour and by the uniform wings. 



Psychoda nigra, nov. sp. 



Black, with dark brown on the thorax and long black hair on the 

 abdomen, wings evenly and quite thickly covered with long black hair, 

 and with a black fringe, which on the posterior margin is about five times

 outside of the tibiae at base. Antenna- slender and a trifle longer than the 

 width of the wing, clothed with white and some black hair, giving them a 

 grayish appearance ; wings narrower than in P. aiternata, and very acute 

 at tip, the posterior margin near tip being almost concave. The ventral 

 plate of the $ is blackish, not much longer than broad, broadest at base, 

 and barely emarginate at tip ; ovipositor more than twice as long as' plate 

 and slightly curved. Length of wing, 2.1 mm. 



One female, captured on a currant-bush at Sea Cliff, N. Y. Separated 

 from all the other species by its uniform black appearance. 



Psychoda mimita, nov. sp. 



Dark, with whitish hair on thorax and gray on abdomen ; wings thinly 

 clothed with gray hair and a gray fringe, which at the posterior margin is 

 about twice as long as the width of a cell ; legs dark with whitish hair.

 each joint in male with a dense whorl of white, appressed hair, which
