Males are blackish-brown dusted with yellow, sometimes quite considerably. The forewings have two subapical yellowish dots, sometimes indistinct and there are three or four submarginal dots close to the margin, usually forming short marginal streaks. The hindwings are more strongly dusted with yellow, with the inner margin and proximal two-thirds of costa yellowish-white. There are short marginal streaks or dots between the veins breaking up a narrow black marginal border defined by the absence of yellow dusting.
Female f. fuliginosus resemble the males, but the upperside has only slight yellow dusting, the forewing dots are more distinct and a postdiscal shadowy band defines a dark patch of ground-colour outside the end of cell. The hindwings have a postdiscal shadowy band. In females of f. ochraceus the shadowy postdiscal band is much more distinctly defined by dense ochraceous dusting, especially on the hind wing. The black discoidal spot on the fore wing is rendered more distinct.
