Above : anterior wings black, the base with a fulvous vitta, 

 occupying in the male nearly the whole of the cell, and in the 

 female extending beyond it across the median nervure ; on the 

 costa is a yellow spot divided by the first and somejtimes also by 

 the second subcostal nervule, below which, upon the third median 

 nervule, is a small oval yellow spot in the male, a larger one in 

 the female, and towards the apex is a short yellow fascia divided 

 by the last subcostal and the first discoidal nervules. Posterior 

 wings of the male fulvous, with the outer margin black, a band 

 of the same colour extending from the hinder part of the inner 

 margin to the outer margin near the termination of the third 

 submedian nervule; the costa widely of a satiny or selenitic 

 white. Posterior wings of the female fulvous, with the fuscous 

 border and the submarginal band rather broader than in the 

 male ; the costa black, divided by a fulvous vitta terminating in 

 a spot of the same colour. 



Below : the anterior wings have the costa brown from the base 

 to the middle ; the apex as above, but paler, and with a series of 

 eight white dots near the margin ; the remainder of the wing 

 whitish, with a selenitic lustre along the middle of the wing, a 

 chalky appearance towards the inner margin. Posterior wings 

 of the male pale dull luteous, yellower towards the costa ; the 

 outer margin, the costa beyond the middle, two bands, one along 

 the middle of the wing, the other near the outer margin, fuscous ; 

 a space above the first band nut-brown ; near the apex are two 

 white dots, and in the fuscous margin three or four faint dashes 

 of white between the nervules. Posterior wings of the female 

 more fulvous than those of the male, the black margin and band 

 broader, the marginal white spots more distinct. 



Head black ; antennae black, dotted with white ; orbits and a 

 patch on the vertex white. 



Thorax and abdomen fuscous ash below. Legs black, lined 

 with white.

In size and form this beautiful species resembles Leptalis Me- 

 thymna, but in colouring approaches nearer to Lept. Amphione 

 and its allies.
