Underside, brown; forewing below vein 2 and terminal margin paler, with a broad band across the cell, the wing medially and at apex suffused with lilac, bearing an incurved postdiscal series of five, blind black ocelli. Hindwing: sub basal and discal narrow transverse lilac bands, the former sinuous, the latter angulated on vein 4, and an arched postdiscal series of black fulvous-ringed ocelli, some with disintegrate centres; the wing medially suffused with lilac, the ocelli with lilacine lunules on both sides. Forewings and hindwings with slender lilacine subterminal and broader ochraceous terminal lines.[3]
Female: Similar to male, with ground colour paler; a broad oblique white discal bar and two white preapical spots on the upper-side of the forewing; a large, rectangular black subterminal mark in interspaces and a white spot above and below it, on the upper-side of the hindwing. Underside similar to the underside in the male, all the markings more prominent, the lilac, ochraceous and brown shades paler; the broad discal bar on forewing, as on the upper-side, joined by a nearly vertical lilacine white band bearing the series of ocelli.[3][4]
On the hindwing, a brown transverse discal band is very broadly produced between veins 4 and 5. Antennae, head, thorax and abdomen brown; antennae ochraceous at apex.[3]
