wing : outer margin longer than inner margin ; cell less than two- 

 thirds the length of costa ; vein 12 reaching costa almost opposite 

 the end of cell; discocellulars inwardly oblique, middle one very 

 much longer than the lower one ; vein 5 very close to bottom of 

 cell ; vein 3 shortly before end of cell ; vein 2 considerably nearer 

 to base of wing than to end of cell. Hind wing very elongate ; 

 vein 7 shortly before end of cell ; vein 3 shortly before end 

 of cell, about twice as far from 2 as from 4; vein 2 considerably 

 nearer to end of cell than to base of wing. Hind tibiae with two 

 pairs of spurs. 



lu the male there are three short longitudinal glandular streaks 

 on the upperside of the fore wing, one in the fork of vein 2, the
