The wingspan is about 30 mm. The forewings are fuscous brown with a slight cupreous gloss with traces of a whitish antemedial line from the cell to the inner margin with a more or less distinct spot beyond it in the cell. There is a quadrate white spot in the end of the cell and a postmedial line forming an elliptical white spot. The hindwings are fuscous brown with a cupreous gloss with a faint dark discoidal lunule and a postmedial line with a small white spot below the costa, then a slight, whitish and bent outwards between veins 6 and 2, then bent inwards to below the end of the cell and more distinct and oblique to above the tornus.[2]
