smaller than in D. tristis , slender, cylindric, scarcely clavate, 
while in D. tristis they are fully twice as broad and flattened 
and near tip roundedly widened.

each side in front of eye and below antenna, and some dark 
on posterior warts, thoracic notum mostly with pale hair, 
some dark near sides ; legs pale ; front legs of male with the 
tibiae dark on inner sides, and also the tips of tarsal joints 
dark. Fore wings a nearly uniform yellowish brown; a 
snow white mark at the end of anal vein, one at base of the 
stigma, and faintly over end of discal cell ; hind wings gray, 
unmarked. 
In fore wings the median cell does not reach nearly as far 
basally as the discal cell (more subequal in transversus ) . 
The male genitalia has the clasper much as in A. trans- 
versus, the apical segment a little shorter, but the curved 
appendage is here very much shorter and stouter toward 
base; in length but little, if any, more than one half of the 
apical segment; each side of the base of the penis is a lobe 
fringed with stout bristles (not in A. transversus ) .
