It is relatively easy to separate this genus from other genera of 

 the Dasyneuriariae by the triarticulate palpi and the 18 to 20 anten- 

 nal segments, in connection with the normal male genitalia. The 

 type species is D. c i r c i n a n s Giraud. The male has 20 antennal 

 segments, the fifth with a stem as long as the basal enlargement, 

 which latter has a length one-half greater than its diameter. The 

 palpi are triarticulate and the claws long and slender. Basal clasp 

 segment stout, the terminal clasp segment stout, tapering; dorsal 

 plate short, broad, triangularly emarginate, the lobes diverging, trun- 

 cate; ventral plate long, divided, the lobes long, tapering, setose. 

 The female has 20 sessile antennal segments, the fifth with a length
