The wings are pale luteous (muddy-yellowish) grey, the forewings with a blackish spot in the middle of the cell and a lunule at the end. There is an antemedial, outwardly curved, brown line. There is also a discal line, more or less crenulated, starting from a spot on the costa, sharply bent inwards below the middle until it nearly reaches below the discal lunule, then straight to the hindmargin, and continued across the hindwings in a nearly straight form, it is disjointed in the middle and the space beyond the outer line is suffused with purple.
