Description
Male. Upperside rufous-brown. Forewing with three semi-hyaline small white sub-apical spots from near the costa, the middle one the smallest and well inwards; in some examples one or both of the lower spots are absent; a large semi-hyaline spot inside the cell, near its end, its inner side square, its outer side deeply excavated, with a small spot between it and the costa, a small round spot near the base of the second median interspace, a much larger round spot in the middle of the first median interspace, and a minute spot (sometimes two) below them in the middle of the interno-median interspace, all these spots slightly tinged with ochreous, and varying much in size in diticrent examples; sometimes the large excavated spot in the cell is split into two, sometimes represented by a small round spot immediately below the sub-costal vein near the end of the cell, and sometimes it is entirely absent; there are some brownish indistinct marks on the wing, one in the interno-median interspace before the middle, a series of conjoined discal marks and an indistinct outer marginal band. Hindwing with a brown spot at the end of the cell, a discal brown macular band, corresponding in its curve to the outer margin, and a marginal band. Cilia of both wings brown. Underside like the upperside, but duller in colour. Forewing similarly marked. Hindwing with the brown bands somewhat more distinct, the cell spot with a brown spot on each side of it, and a sub-basal brown spot. Female similar to the male.
