Fore and hind wings densely ciliate discally, the cilia short and 

 close ; marginal cilia of both wings short and close, longer on the hind 

 wings" Marginal vein of fore wings subequal to or slightly shorter than 

 the submarginal vein, the postmarginal vein equal to half the length of the 

 marginal, and nearly twice the length of the stigmal vein, which is bifurcate 

 at apex. 



Antennae filiform, not very long, the scape cylindrical and of 

 moderate length, the funicle 4-joinled, the club 3-jointed, and with a 

 single ring-joint. Pedicel small, obconic, about a third of the length of 

 the long first funicle joint; ring-joint minute; first funicle joint 

 cylindrical, the longest antennal joint, wider than the pedicel and a fourth 

 longer than the following joint ; funicle joints 2 and 3 subequal, cylin- 

 drical oval, joint 2 slightly longer and slightly narrower than joint 3, and 

 both distinctly shorter and broader than joint i of the funicle ; funicle 

 joint 4 subquadrate, of about the same width, but only about two-thirds 

 of the length of joint 3 ; proximal club joint large, half the length of the 

 club, but distinctly smaller than the apical funicle joint ; the intermediate 

 club joint smaller, conical, not much larger than the pedicel, about a little 

 over half the size of the proximal club joint ; the apical or discal joint 

 minute, nipple- or spur like. Funicle and club hispid, with white hairs, of 

 which there are about three transverse rows on the first funicle joint, and 

 two rov/s on each of the following funicle joints and the proximal club
