its upper end, 9 from beyond the middle of 7, 6 from upper end of cell, 5 from a little 

 above the middle of discocellulars ; lower discocellular upright, twice as long as the upper, 

 both in a straight line ; vein 4 from lower end of cell, 3 from a little before the end, 

 2 from near the origin of 3 ; sub-median nervure straight ; costa arched, apex sub-acute, 

 outer margin slightly outwardly oblique from apex to vein 5, then straight to the 

 hinder angle ; hinder margin sinuous, produced into a bluntly rounded lobe near the 

 middle, a tuft of long white hairs on its outer edge, turned upwards and lying flat 

 against the underside of the wing ; another tuft of long white hairs from about the 

 middle of the sub-median interspace on the upperside of the wing which is turned down- 

 wards, and lies across a patch of dark scales, differently formed to the other scales of the 

 wing. Hindwing with vein 8 arched, not reaching to the apex, 7 from one-fourth 

 before upper end of cell, arched and ending at the apex ; 6 from upper end, 5 from 

 the middle of discocellulars which are straight and slightly outwardly oblique, the 

 lower a little the longer ; vein 4 from lower end of cell, 3 from immediately before the 

 lower end, 2 from one-fourth before the end, sub-median nervure straight, internal 

 nervure recurved. Costa much arched, apex rounded, outer margin slightly convex, 

 with slight productions at the ends of veins 2 and 3 ; a filamentous tail at the end of 

 vein 1 and another at the end of vein 2, rather long and of equal length ; a well 

 formed anal lobe, just above which the abdominal margin is shortly excavated, then 

 slightly convex to the base ; a large rounded patch of dark differently formed scales on 

 the upperside of the wing in the costal interspace, covering the base of the sub-costal 

 interspace and also extends somewhat into the discoidal cell.

Imago. — Male. Upperside azure-blue. Forewing with black costal and outer 

 marginal band, narrow at the base, gradually widening along the costa, broad at the 

 apex and narrowing down the outer margin to a point at the hinder angle. Hindwing 

 with the costal space and abdominal fold whitish, the outer margin with a fine black 

 line ; anal lobe blackish ; tails black, tipped with white. Underside pale brown with a 

 pink tint ; a narrow even white band, from the middle of the costa of the forewing 

 straight down to vein 2 of the hindwing. Forewing with the hinder marginal space
