 for terms used

Upperside of male dark brown. Fore wing with transverse discal, postdiscal and subterminal series of bluish spots, the latter two series closely approximate. Hind wing uniform except for the prominence of the discal secondary sex-mark, and faint indications of a subterminal series of pale spots. Underside a dull ochraceous brown, the basal half of the wing is darker, denned outwardly by a still darker but obscure transverse band ending in a lilacine diffuse small patch at the torn us of the hind wing; both fore and hind wing irrorated somewhat sparsely with short transverse brown striae and obscurely tinted with lilac; two ill-defined ocelli on the hind wing as in Discophora celinde. Antennae ochraceous; head, thorax and abdomen brown, paler beneath.

Female has an upperside of purplish brown. Fore wing with three transverse series of white spots, the inner or discal series continued to the costa by two large elongate obliquely-placed white spots. Hind wing also with three transverse rows of somewhat obscure spots, but ochraceous in colour. Underside similar to that in the male, but paler.

Larva

"On bamboo, living during the day in three or four leaves spun together .... full-fed larva 2 inches long, colour black mottled with grey ; a rather broad yellowish dorsal line ; the junction of the segments marked by a thin irregular yellow line and red spot; body covered with white hairs; head and anus black, the former marked with perpendicular yellow lines." (Manders, Trans. Ent. Soc. 1890, p. 519.)

Pupa

".. white, suspended by the tail; the labial palpi prominently projected; changing to dark brown a few hours before emergence. The perfect insect remains three weeks in pupa." (Manders, Trans. Ent. Soc. 1890, p. 519.)
