Underside, forewing: basal third and a large spot on the discocellulars, that is widened anteriorly, rich dark cinnamon-brown; medial third lilacine, pale towards the dorsum, widened anteriorly and extended into the apex of the cell, and on the costa from the discocellulars to near the apex of the wing; interspaces 2, 3 and 4 with paler lilacine (lilac-coloured) lunules; terminal third of the wing dull brown, with a postdiscal and a subterminal transverse series of somewhat obscure olivaceous-yellow lunules.

Hindwing: basal third rich dark cinnamon brown in continuation of that colour on the forewing; remainder of the wing lilacine, with a large posterior discal patch of cinnamon brown, margined inwardly by a diffuse broad irregular white band, and outwardly by a series of white lunules; a subterminal somewhat obscure row of olivaceous-yellow markings; the tail and terminal margin dark cinnamon brown.

Hindwing: the lilacine white colour of the discal band spreads to the base of the wing, but is thickly irrorated (sprinkled) with brownish scales, as is also the outer margin posteriorly of the same band; the rest of the wing dark brown, with the margins of the tornus and of the tail broadly bright cinnamon brown; lastly, superposed on the brown area is a sub-terminal series of large, yellow, well-defined more or less lunular spots.

Underside similar to that of the male, the ground colour and markings on the outer two-thirds of both forewing and hindwing paler.
