Imago. — Male. Upperside shining blue tinged with purple, costal line of forewing 

 and terminal line of both wings black, with a sub-terminal series of indistinct brown 

 marks. Cilia grey, brown at the base ; tails black, tipped with white. Underside pale 

 purplish-brown, with a chocolate tint ; markings dark brown, with pure white 

 edges. Forewing with three transverse bands, the first antemedial, across 

 the middle of the cell down to the hinder margin ; the second across the end 

 of the cell, with a short square mark above it, also to the hinder margin, slightly 

 disjointed at the lower end of the cell ; the third commences below the costa, 

 where there is a short square, is dislocated at vein 7, where it recommences a little 

 outwards, runs down the two next interspaces, is dislocated on vein 4, and has there 

 an inside square filling the next interspace, touching the outer side of the second band. 

 Hindwing with a square bar near the base, another at the end of the cell, a complete 

 transverse band between them, with an inward curve in its centre, an outwardly curved 

 discal band, broader and darker than the others, which narrows hindwards, touching the 

 outer lower edge of the band at the end of the cell, and then breaks up into double 

 lunules in the lower interspaces ; both wings with a double series of dark brown, rather 

 large, sub-terminal lunular marks, capped with white lunules, a large deep black sub- 

 terminal spot in interspace 2, capped with orange, and two at the anal angle, all with 

 metallic blue-green scales. Antennae black, speckled with white ; head and body 

 blackish, with blue pubescence, white beneath ; palpi with a black fringe. 



Female. Upperside. Forewing with very broad outer marginal blackish border, 

 broadest at the hinder angle, extends also down the costa, narrowing towards the base 

 of the wing; the inner portion of the wing whitish with shining blue scaling. 

 Hindwing nearly all blackish-brown, with some shining blue scaling on the inner 

 portion below the median vein ; a sub-terminal, very indistinct series of double brown 

 marks. Underside paler than the male, markings similar.
