The angulated apex of the fore wings, and the produced anal 

 angle of the hind wings, distinguishes this insect from all the other 

 species of the genus. The male has the upper surface of the 

 wings of an intense dark blackish purple, with the outer limb paler 

 brown, a few fulvous scales forming a small spot near the costa 

 at about one-sixth of the length of the wing from its extremity ; 

 the hind wing is unspotted. 



The upper surface of the wings of the female is much paler 

 than in the male, with a rich but paler blue gloss not extending 

 beyond the basal half of the wing ; near the middle of the costa 

 arises a very oblique abbreviated buff" fascia, and parallel with the 

 apical margin is a row of small oval dark buff" dots ; the hind 

 wings are unspotted. On the under side the fore wings in the 

 female are marked by a conspicuous pale buff' oblique narrow 

 fascia running from near the middle of the costa towards the anal 

 angle, near which it is waved and recurved, not joining the slender 

 pale buff" nearly straight submarginal line ; within the discoidal 

 cell are several small patches of luteous scales, obsoletely in- 

 dicating fasciae. In the male the central oblique fascia of the 

 female is indicated only by a slightly paler tint in the correspond- 

 ing part of the wing. The hind wings have a pale slender striga 

 running from within the outer angle to within the anal angle, 

 which is outwardly marked with a pale and a black spot; across
