porrect, divergent ; third joint long and slender. Fore wing : inner 

 margin longer than outer margin ; no costal fold in male : cell two- 

 thirds the length of costa ; vein 12 reaching costa well before the 

 end of cell ; discocellulars suberect ; vein 5 slightly nearer to 6 thon 

 to 4 ; vein 3 shortly before end of cell, more than three times as far 

 from 2 as from 4 ; vein 2 rather more thau twice as far from end of 

 cell as from base of wing Hind wing: vein 7 shortly before end 

 of cell ; discocellulars and vein 5 hardly traceable ; vein 3 just before 

 end of cell : vein 2 about equidistant from base of wing and end of 

 cell. Hind tibife very short, only with terminal pair of spurs, which 

 are very long. 



In the male there is a tuft of hairs attached to the proximal end 

 of the tibite, much exceeding the tibiae in length, and fitting into a 

 groove behind the lirst joint of the tarsi, which is much elongated 

 and slightly swollen. In the female the hind tibiee are longer than 

 in the male, and the terminal spurs are shorter.

Antennae : club very slender, almost filiform, almost straight. 

 Third joint of palpi short, conical, projecting slightly from the 

 clothing of the second joint. Fore wing : inner margin slightly 

 longer than outer margin ; no costal fold in male ; cell more thau 

 three-fifths the length of costa; vein 12 reaching costa almost 

 opposite to end of cell ; discocellulars almost erect, subequal : vein 5 

 slightly nearer to 6 than to 4 ; vein 3 well before end of cell, less than 

 twice as far from 2 as from 4 ; vein 2 remote from 3, more than 

 twice as far from end of cell as froai base of wing. Hind wing : 

 vein 7 well before end of cell ; discocellulars erect, very faint ; vein ^) 

 barely traceable, nearer to G thau to 4 : vein 3 just before the end 

 of the cell, nearer to 4 than to 2 ; vein 2 about equidistant from 

 base of wing and end of cell. Hind tibiie with only a single pair 

 of spurs.
