cell is broad at base. In hind wings the discal cell is about as long 

 as the pedicel, and as long as any apical cell; all apicals broad at base, 

 but the fourth rather narrower than the others; the vein from the 

 posterior anastomosis arises much nearer to the cubitus than to the 

 median, and then curves forward. 

 Expanse, 44 mm. 



One female from South Park, Col., 25 May (Oslar) ; others 

 from Wellington, B. C, and Tabernash, Colo. 



Pycnopsyche similis, n. sp. (PI. IX, fig. 25). 



Head and thorax reddish yellow, palpi pale yellowish, antennae rather 

 reddish yellow; legs pale yellow, with black spines; abdomen pale 

 at base, nearly black at tip ; fore wings pale yellowish, outer edge 

 broadly bordered with brown, a brown spot in base of third apical 

 cell, containing a darker dot, another smaller in fifth apical cell, 

 and three discal brown spots forming a discal band like that of P. 

 guttifer and Platyphylax subfasciata, but not quite as long; a hyaline 

 spot on the thyridium before the fork ; venation pale ; hind wings 

 hyaline, venation pale. Wings shaped and veined as in P. guttifer. 

 No macrochseta back of ocelli, but hairs on the vertex, thoracic strips 

 very short and narrow, with only five or six tubercles in each ; spurs 1-3-3. 



Expanse, 30 mm. 



Two specimens from Agricultural College and Chatham, 

 Mich., August, September. 



Very similar to P. guttifer (PI. IX, fig. 22), but distinct by 

 genitalia of male. 



Phryganomyia, n. gen. 



A limnephilid; no spines on last joint of hind tarsi; fore wings 

 rather slender, apical cells very long and narrow, first not reaching 

 far on discal cell; in hind wings the discal cell is very short, and there 

 is a cross-vein from the first apical sector near its base connecting to 

 the radius; spurs 1-3-4; ocelli very large; no macrochaeta back of the 

 ocelli; maxillary palpi short, in the male .the basal joint is as long 

 as either of the other joints, a condition very rare in the Limnephilirise. 



Type: Asynarchus alascensis Banks. 



The genus Phryganomyia includes also the following new 

 species.

Phryganomyia obscura, n. sp. (PI. VIII, fig. 6.). 



Head, antennae, and palpi yellowish, vertex with yellowish hair, but 

 no macrochaeta back of the extremely large ocelli; thorax yellowish,
