Male forewing upperside: entirely without the thick coating of short hairs on the outer half.

Hindwing: the upper discal white patch larger, formed of elongate broad streaks in interspaces 4 to 7 (not 5 to 7): no tornal nor subterminal markings.

Underside ground colour duller brownish black; forewing with the diffuse scaling so disposed as to form grey cellular and internervular streaks, the streaks in interspaces 1a and 1 generally white, not diffuse.

Upperside ground colour browner; forewing: cellular and internervular streaks more prominent; in many specimens an obscure diffuse whitish subcostal shading just beyond apex of coll.

Forewing with the cellular and internervular streaks and subcostal postcellular whitish patch more prominent; the posterior three internervular short streaks on the outer half of the wing white, not diffuse; in a few specimens there is a series of more or less conspicuous admarginal white spots, one in the middle of each interspace.
