Hind wing: costal margin diffusely dusky black, termen with a slender black anticiliary line; dorsal margin narrowly pale. Underside: white with a slight tinge of blue. Fore wing: a short line on the discocellulars, a postdiscal transverse series of six abbreviated lines pointing obliquely outwards and en echelon one with the other, the uppermost shifted well inwards, followed by a sub-terminal series of transverse spots enclosed between an inner subterminal, lunular, transverse line and an outer anticiliary slender line, pale brown. Hind wing: a transverse subbasal series of three, sometimes four, minute spots and a spot beyond on the dorsum, with a larger subcostal spot near the apex of the wing, black; a short slender line on the discocellulars and some irregular dots on the disc pale brown; terminal markings as on the fore wing. Cilia of both fore and hind wings whitish. Antenna, head, thorax and abdomen dark brown, the antennae ringed with white beneath: the palpi, thorax and abdomen white.
