The postmedial line is black, defined on the outer side by white forming a small triangular spot on the costa. There is also a black line just before the termen from the costa to the submedian fold, as well as a fine black terminal line. The hindwings are brownish grey, irrorated with black. There is a black discoidal spot with a diffused line from it to the inner margin. The postmedial line is black, defined on the outer side by grey, with blackish suffusion beyond it extending on the costal area to the termen.
