HW with a vaguely defined central orange patch and relatively narrow dark borders. Female FW appears darker brown, with more-prominent dark markings in the orange field, and inner edges of dark trailing border are noticeably convex. Orange patch on female HW more sharply defined, and crossed by dark veins.
