Flint — Neohermes 
257 
The male t3^pe of the species is present at the Museum of Compara- 
tive Zoology at Harvard University. In addition to the type many 
more specimens of the species from New Mexico, Arizona, and Cali- 
fornia have been studied. Although this species and calif ornicus are 
both found in California, they occupy different ranges within the state. 
The male is easily separated from the closely related N. calif ornicus 
by the shape of the anal plate which is not bifurcated but produced 
apicoventrally. The females of the two species are difficult to 
separate although the anal plate is usually not produced into a point 
in filicornis. 
Male genitalia. — Ninth tergum large, sternum scoop-like. Anal 
plate with apicoventral angle produced, bearing mesally many short 
black setae in this region; apicodorsal angle rarely slightly produced. 
Aedeagus scoop-shaped, apex produced into a pair of submesal lobes, 
from which run rather straight ridges to the base; lateral margin 
evenly convex. 
Female genitalia. — Anal plate triangular, with apical point barely 
developed. Gonapophysis lateralis without papilla. 
Length of forewing. — male (70 examples) 29 to 50 mm., ave. 
39.0; female (25 examples) 37 to 54 mm., ave. 45.8.
