Forewings rather dingy; light brownish grey, with indistinct, darker irregular striae, dark fuscous on the costa, the veins marked blackish and whitish except within the median band, with a whitish subterminal line forming a white tornal dot, and a black discal dot connected with the costa by a dark fuscous streak. Forewings with a dark discal mark. Forewing fringes conspicuously chequered.

The termen of the hindwings somewhat dentate; hindwings brownish grey, like the forewings; hindwings patterned similarly to the forewings; hindwings conspicuously patterned; hindwings conspicuously transversely striated (with dark, wavy basal, median and outer striae, and a zigzag marginal one); hindwings with a clear discal mark to without a clear discal mark; fringes conspicuously chequered.

Neuration. Vein 10 of the forewings arising independently, anastomosing with 11 and 9 to form a double areole.
