Imago. — Male. Upperside dark purple-blue. Forewing with a black costal line 

 and a black outer marginal band of fairly even and moderate width. Hindwing with 

 the immediate costal space, narrowly, somewhat paler than the rest of the wung, a 

 broad costal and outer marginal band broader than on the forewing, tail at the end of 

 vein 2, black, tipped with white, slight projections at the ends of veins 1 and 3. 

 Underside. Forewing coloured and marked exactly as in A. asoka. Hindwing brown 

 glossed with greyish, varying in shade in different examples, the basal portion dark, 

 well glossed with grey, a large dark, sub-basal patch on the costa with two large round 

 spots, pale edged, one above the other on its basal side, an irregular paler coloured 

 band of spots (pale edged) across the middle of the wing, of which a large, curved, sub- 

 quadrate spot at the end of the cell is the centre, an outwardly curved and much 

 suffused broad discal band, darker than the ground colour, inwardly limited by an 

 irregular line of curves, a sub-marginal similar line, brown terminal line, with a small 

 black sub-terminal spot in the second interspace ; these marks are fairly prominent in 

 examples where the ground colour is pale, but in most specimens the ground colour is 

 dark and hardly any of these marks are traceable. 



Female. Upperside. Forewing ultramarine-blue, generally brighter than in 

 A. asoka, with similar broad black mai'ginal bands and black discoidal mark. Hindiring 

 with very broad black costal and outer marginal bands, the ultramarine-blue portion of
