Male upperside, forewing: black; a medial triangular area that extends from base outwards to the disc white, suffused at base and anteriorly with iridescent blue that spreads upwards on to the black of the costa; along the dorsum the black ground colour is much paler, in most specimens diffuse fuscous.

Hindwing: white, basal third and costal margin broadly suffused with fuscous, the fuscous at base posteriorly overlaid with iridescent blue; a subterminal series of fuscous-black dots and a distinct but very slender black anteciliary line.

Underside: white very slightly tinged with bluish; markings all fuscous black, minute and very slender.

Forewing: a short discocellular line followed by on anteriorly, strongly curved, discal series of very short detached lines and a more or less obsolescent transverse series of subterminal dots.

On the former it spreads well into the cell, the latter three-fourths of the wing are white; the dusky basal and costal areas much more restricted than in the male.
