Hydropsyche analis, sp. nov. 



Head black, with sparse black hair. Antenna; brown, annulate with pale; 

 thorax black, with some black and yellowish hair ; legs pale yellowish, a dark mark 

 on tips of tibire, and the tarsi dark ; abdomen brown. Wings a uniform brown, 

 except a triangular white mark at end of anal vein, surface very sparsely clothed with 

 short golden hairs ; hind wings not so dark as fore pair ; venation brown. Anterior 

 wings rather narrow, hind pair with a rather long fringe on posterior margin. Length 

 to tip of wings 7-8 mm. 



Several specimens from Ithaca, N. Y., May till July; and River- 

 ton, New Jersey, July 16. Easily known from our other species by 

 the uniform brown wings, except the anal white mark. 



Pellopsyche, gen. nov. 



Venation like Philopotamus and Dolophilus except that the cross-vein which in 

 those genera arises from the base of the thyridial cell in this genus arises beyond 

 middle of that cell and continues across the cubitus to the anal vein ; this probably 

 being due to the wing being narrower than in those genera. Discal cell short and

narrow ; both branches of the radial sector forked beyond anastomosis ; upper branch 

 of medius forked beyond the anastomosis, lower branch at anastomosis. Spurs 2-4-4 ; 

 ocelli present ; palpi slender and long, antenna as long as wings, first joint enlarged. 



Pellopsyche signata, sp. nov.

 joints are narrowly brown ; palpi pale ; legs pale ; spurs yellowish ; abdomen pale
