Hindwing with base brown; subbasal fascia white; tornal spot silver grey preceded by a yellow streak; antemedian fascia white, edged brown on each side; median zone with clear submarginal edge leaving a white band before five eye-spots, 2 and 4 being larger than the others; eye-spots separated by leaden studs, with a small area of orange above; terminal cilia silver-grey with pronounced cilia line.
Foreleg of male with blackish tibial epiphysis and black distal tibial spines; foreleg of female with just the epiphysis.
