termen slightly concave, sinuous ; tornus blunt ; dorsum slightly 

 sinuous ; cell closed, not quite half length of wing ; upper disco- 

 cellular minute ; middle oblique, slightly concave ; lower also 

 oblique but longer, more strongly concave ; vein 3 from just 

 before lower apex of cell, 4 from apex, 8 and 9 from terminal 

 half of 7, 10 and 11 free. Hind wing irregularly oval ; costa 

 arched ; termen from vein 1 to vein 4 produced, elongate at 

 vein 4, forming a conspicuous tail, above the latter to apex and 

 below to the tornus scalloped ; tornus angulated, dorsum just 

 above it widely emarginate, then convex to base ; cell open, but 

 apparently closed by a transverse fold in the membrane of the 

 wing between veins 4 and 5 well on towards the terminal margin. 

 Antennas long and slender, more than half length of fore wing : 

 club long, narrow, gradual ; palpi broad in front, subporrect, 

 blunt at apex, third joint short ; eyes naked ; thorax moderately
