Imago. — Male. Upperside very dark purple, with a cyaneous gloss in certain 

 lights. Forewing with black costal and outer marginal line. Hindwing with the 

 costal space narrowly somewhat paler than the rest of the wing, the outer margin 

 sometimes with a black line, which has some obscure blackish on its inner side, tail at 

 the end of vein 2 blackish, tipped with grey, slight productions near the anal angle 

 (which generally has a blackish spot on it), and at the end of vein 3. Cilia black, with 

 grey tips. Underside chocolate-brown, band and spots darker brown, with pale 

 edges, the costal base of both wings with a short, dull scarlet streak. Forewing with 

 the hinder marginal space pale, the basal half above the median vein dark brown ; 

 having in it, near the end of the cell, an elongated narrow pale space, a rather broad, 

 outwardly curved discal band, from the costa to vein 2 narrowing hindwards, a large 

 sub-quadrate spot across the interno-median space, its upper inner edge touching the 

 lower outer edge of the basal patch, a sub-marginal series of brown marks. Hindtving 

 with the basal fifth dark brown, a pale curved bar at the end of the cell, indicated by 

 its brown edgings ; above this, but a little on its outer side, is a recurved similar mark 

 from the costa to near the outer upper end of the discoidal bar, this mark is really the 

 upper part of the usual discal band, which is continued on vein 6, well outwards and 

 well separated from its upper portion, and consists of six conjoined spots in an even 

 curve which narrows towards the abdominal margin, marginal line brown with a pale line 

 inside it, a sub-marginal lunular line, and between this and the discal band is a diffused 

 dark brown band, a black spot at the anal angle, another in the second interspace, both 

 capped with metallic blue scales. 



Female. Upperside. Forewing, cyaneous-blue with broad costal and outer 

 marginal blackish bands. Hindwing nearly all blackish, the centre portion cyaneous, 

 varying somewhat in extent in different examples. Underside as in the male, but all 

 the bands narrower.

Genitalia. — Specialised in every point, the tegumen with its extraordinary beak- 

 shapsd hook and projection below this, the hooks recurved at their tips ; the clasps 

 small and evenly oblong ; the penis stout, curved, with a globose orifice, at the tip of 

 which is a strong thorn -like spur. 



Larva. — Limaciform, black, marked with longitudinal reddish-brown and pale 

 yellow stripes ; the segments well defined, the sides furnished with numerous short 

 bristly hairs ; the head small ; the second segment usually large, pale yellow, marked
