Forewing: discoidal streak clavate, bi-indentate above; a contiguous spot at base of interspace 3; a short, outwardly oblique band from middle of dorsum contracted in the middle; another outwardly oblique, somewhat macular, short, broad, preapical band from beyond middle of costa to interspace 4, with two small spots above it in interspaces 5 and 6.

Underside, ochraceous orange with numerous spots and lines of ferruginous, that form on forewing a short, outwardly oblique streak not extending beyond interspaced, and on hindwing a sub-basal transverse streak in continual ion of the above streak on the forewing; also on both wind's a series of obscure postdiscal cone-shaped marks, irrorated and rendered indistinct on the hindwing by a large patch of pink scales turning to a bluish lunule in interspace 3; forewing with a ferruginous, hindwing with a pale yellow subterminal line.

Antennae black, ochraceous at apex; head with ferruginous pubescence; thorax and abdomen black on upperside, ochraceous beneath.
