This species is quite distinct from the other nearctic 
species of the genus on the basis of the cercus (see original 
description). It has been considered a subspecies of 
designatus Wlk. erroneously by Milne (1935). 
Hesperophylax occidentalis Banks, 1908b, p. 265, pi. 19, 
fig. 16. ( Platyphylax ) 
Lectotype , male. — Florrisant, Colorado, August 3, 1907, 
S. A. Rohwer. No. 11646. Lectoallotype, female. — Ft. Win- 
gate, New Mexico, August, Wingate. 
A close ally but not a synonym of designatus ( Wlk.) . 
Homophylax crotchi Banks, 1920, p. 345. 
Lectotype , female. — Victoria, British Columbia, July, 
Crotch. No. 10877. 
The striking wing pattern of yellow and dark brown will 
serve to identify this species. 
Homophylax flavipennis Banks, 1900a, p. 255. 
Lectotype, male. — South Park, Colorado, August 23, 1899, 
Oslar. No. 11635. Lectoallotype, female. — Same data. 
The male genitalia show many points of similarity to those 
of Glyphopsyche. 
Leptophylax gracilis Banks, 1900a, p. 252. 
Lectotype, female. — St. Anthony’s Park, Minnesota. No. 
11637. 
The male was described by Betten (1934, pi. 44, figs. 2-5) . 
This seems to be one genus of the Limnephilus group suffi- 
ciently distinct to be recognized. At least, it can be keyed 
out in both sexes without difficulty. 
Limnephilus Leach 
Inability to find satisfactory characters for segregating 
the females into the same groups as the males has led me to 
consider as only of subgeneric rank such groups as Anabolia, 
Anabolina, Colpotaulius , Goniotaulius and some others. 
Limnephilus abbreviatus Banks, 1908b, p. 263, pi. 18, fig. 8.
