The upperside ground colour is rich silky brown. The forewing has the cell filled with a broad orange-yellow streak which is subapically deeply indented above; a small discal orange-yellow spot present in interspace 1; a much larger, similarly coloured discal spot between veins 2 and 4, on the inner side touching the cell between veins 3 and 4; a subcostal white preapical spot and a quadrate double spot in interspaces 4 and 5, placed obliquely forward to the subcostal spot; this spot whitish above, orange below. Hindwing uniform, with an irregular curved, transverse, upper postdiscal orange patch extending from just below vein 3 to interspace 6, the portion in interspace 6 often detached. Underside ground colour: forewing brown, apex pale purplish irrorated (sprinkled) with minute dark transverse striae and dots, orange markings as on the upperside but paler; hindwing uniform pale purplish irrorated with minute dark dots and transverse striae.
