The male has the wings above black-brown, glossed with 

 intense purple blue, most conspicuous on the anterior pair; at 

 about one-sixth of the length of the wings from the tip is a 

 minute pale dot scarcely visible, the outer margin of the wings 

 from this dot to the anal angle being of an uniform brown colour, 

 the dark glossed part terminating in a series of waves. 



The female is of a much paler brown on the upper side, and the 

 blue much less intense in its gloss ; it extends also only to about 

 half the length of the wings, being bounded in the fore wings by 

 an oblique whitish line, extending from near the middle of the 

 costa towards the anal angle ; near the apical angle are two luteous 

 spots, followed by a waved line, extending to the anal angle ; the 

 hind wings with a waved dark brown subapical line, the space 

 within which is rather paler. 



On the under side the male has the wings of a dark rich 

 brown and the females of a paler brown. There is an oblique 

 pale bar running across the middle of the wing, recurved at its 

 lower extremity, so that it does not unite with the lower extremity 

 of the wide dark obconical inner boundary of the broad pale apical 

 margin, through which runs a slender dark waved line (almost 

 obliterated in the male) ; there are also some patches of pale 

 scales (most conspicuous in the female) within the discoidal cell, 

 indicating rudimental fasciaa. The hmd wings are also traversed 

 a little before the middle by a nearly straight dark line, edged on 

 its outer margin with pale scales, and which unites near the anal 

 angle with the wide dark obconical inner boundary of the wide 

 pale apical margin, through which also runs a deeply waved dusky 

 line, between which and the dark inner boundary there is a thick 

 sprinkling of pinkish scales. Within this dark boundary line are 

 also two black ocelli, slightly powdered with blue scales above, 

 and surmounted by pale yellow crescents. The basal portion of 

 the hind wings is also powdered with patches of pale scales, in- 

 dicating several dark rudimental fasciae. 



The four branches of the post-costal vein are arranged nearly 

 as in Th. Odana^pl. 19, fig. 1 c), and the male has a double patch 

 of black hairs at the base on the upper side (fig. 1 6).
