The hindwing beneath more or less dusted with grey at the base, the externally somewhat dentate central area being dark brown, the submarginal band pale ashy grey and the distal area of the same colour as the central area. The female is lighter throughout, the forewing having a brownish tint and a somewhat longer and broader submarginal band on the hindwing the basal area and the submarginal band whitish grey, the central area and distal margin grey-brown. - From East Siberia: at Pokrofka and the mouth of the Jenisei, in June.[2]
