Genitalia: Sagitta strongly compressed, blade-like, but of considerable 
width dorso-ventrally, obtuse, of moderate length, and with the apical portion 
somewhat deflexed; the volsella forms a comparatively large chitinous but-

with a patch of erect, stiff bristles; squama rather short and broad, its tip 
mucronate; uncus as seen from the side strongly arched, narrowed in the mid-

the apical third widened, and the apex with a deep, almost rectilateral notch. 
The description of the genitalia is drawn from a specimen from 
Arizona in the collection of Cornell University.
