with whitish hair; abdomen dark brown, appendages pale yellowish; 

 legs pale yellow, with yellowish spines and spurs. Fore wings dull 

 yellowish hyaline, venation pale brown; faint traces of brown irrora- 

 tions on hind part of the wings; hind wings yellowish hyaline, vena 

 tion pale. Fore wings rather slender, discal cell plainly shorter than 

 pedicel, not nearly as long as the apical cells, first and second apicals both 

 with oblique bases, fifth scarcely reaching before the fourth, cubitus 

 disjointed at posterior anastomosis. In hind wings the discal cell is 

 very short, only about one-third the length of its pedicel, apical cells 

 very long, fifth reaching only a little before fourth. 

 Expanse, 2.2. mm. 



One specimen from Tupper Lake, Minn. (Pettit). 



Ecclisomyia, n. gen. 



A limnephilid; no spines on last joint of hind tarsi; spurs 1-2-4; 

 fore wings rather long, the discal cell is very long, and the first apical 

 cell is more than twice the width of discal cell upon the latter; the 

 outer margin is rounded; in the hind wings the fourth apical cell is 

 not narrowed at base. Ocelli large, no macrochseta behind them; the 

 basal joint of antennae rather longer than usual. 



Type: E. ccmspersa, n. sp.

 membrane with short black hairs, venation pale brown; hind wings 

 hyaline, venation pale. In the fore wing the discal cell is three times 

 as long as its pedicel, yet barely as long as the third apical cell. 



Expanse, 27 mm. 



One specimen from Olympia, Wash. Differs from E. macu- 

 losa in larger size, absence of pale spot on thyridium, larger 

 spot on arculus, etc.
