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 mervm’e ; 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 ; antennse 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.
