LiMNEPHILUS ADUSTUS, Sp. nov. 



Type.— M. C. Z. 10,879. Alberta: Banff, 21 August (N. Sanson). 



Black, with black and yellow hair; antennae (except basal joints) and legs 

 (except the femora) brownish to yellowish, most of head and thorax above 

 with yellow hair; legs with black spines. The ocellar macrochaetae farther 

 back than the ocelli and also much closer together than are the ocelli, first 

 joint front tarsus one and two thirds as long as second. Fore wings yellowish 

 with much yellowish hair, and two large brown spots; one from the posterior 

 anastomosis outward, the other over the outer two thirds of the third apical 

 cell, extending on sides a little into the adjoining cells; stigma dark, and anal 

 area slightly infuscated; radial sector but little bent at the stigma. The 

 male genitalia in general similar to L. kincaidi but the superior appendages 

 longer; the lower intermediate pair- (which are golden) form a half circle, 

 when seen from behind. 



E.xpanse 22 mm. , 



LiMNEPHILUS CRASSUS, sp. nOV. 



Type.— M. C. Z. 10,871. Massachusetts. 



Yellowish, with yellowish hair, some brown hair each side on face and on 

 sides of pro- and mesothorax; legs with black spines. Fore wings with pale 

 costal space, elsewhere mostly brown, heavily mottled with pale; a large, 

 oblique spot over th>Tidial cell as usual, and one in the bases of apical cells; 

 hind wings hyaline. Ocellar macrochaetae behind ocelli, and ahiiost as far 

 apart as are the ocelli; radius curved at stigma; in hind wings the fourth 

 apical cell is more than one half as wide as the third at base. The male 

 genitalia shows a large superior plate, with two flat, divergent processes, 

 which are brown toward tips. 



Ex-panse 27 mm. 



LiMNEPHILUS MORRISONI, sp. nO\-. 



Type.— M. C. Z. 10,873. Nev.: Reno (H.K.Morrison); Sierra 

 Nevada (G. R. Crotch). 



Pale yellowish, with mostly yellow hair and bristles; palpi of female only 

 moderately long; ocellar macrochaetae almost between the ocelli. Fore wings 

 pale brownish; the usual oblique pale mark over thyridial cell; a spot just 

 before the anastomosis, extending backwards below; part of the fourth and 

 most of fifth apical cells with pale spot extending into apical part of first 

 subapical cell; one or two small pale spots above middle of the discal cell; 

 practically no other pale marks, and all of these may be very faint. The
