Hind wing: the ocelli of the underside showing through, sometimes forming two or three obscure black spots ; two slender subterminal black lines. Underside paler, shaded with dark brown. Pore wing: narrow subbasal and outer cellular transverse sinuous white lines ; an irregular broad discal and a narrower postdiscal band white, forming a V, the latter bearing a series of four blind, dusky-black, fulvous-ringed ocelli; the two preapical white spots as on the upperside. distinct slender subterminal whitish and broader terminal ochraceous lines. Hind wing: a subbasal transverse sinuous white line; a postdiscal arched series of six black ocelli, their centres disintegrated, their inner ring ochraceous, outer brown, and the whole series bordered inwardly and outwardly by lilacine white lines; finally a slender white subterminal and a broader ochraceous terminal line as on the fore wing.
Female Upperside differs in having a broad, oblique, white, discal band on the fore wing and a spot below its posterior end in interspace 1, the inner border of the band bi-emarginate, the outer irregularly sinuous..
