Imago. — Male. Upperside dark glossy purplish-brown. Furewing with a trans- 

 verse lower discal inwardly-oblique band, this band being composed of a series of 

 five purplish-wbite spots, the uppermost smallest (but sometimes absent) being 

 situated above the upper median veinlet; an obscure submarginal ocelloid spot 

 between the middle and lower median veinlet slightly visible. Hindwing crossed by 

 a continuous but broader purplish-white discal band, the abdominal margin being 

 greyish white ; a submarginal row of obscure paler brown lunules, a black ocelloid 

 subanal spot between the lower medians, and an obscure marginal paler brown line. 

 Underside glossy pale purplish-white. Both wings crossed by a slightly-defined 

 slender pale brown irregular discal line, which also inwardly borders the slightly 

 apparent discal white band. Forewing also with a slightly- defined small pale brown 

 spot within the cell, a slender bar at its end, a submarginal zigzag fascia, and a 

 marginal line ; a small outer pale ochreoas ocelloid spot with black centre and outer 

 brown ring situated between the lower medians. Hindiving also with a pale brown 

 upper submarginal zigzag fascia, an entire marginal line, and a subanal pale ochreous 

 ocelloid spot with black centre and brown outer ring situated between the lower 

 medians. Body and palpi above brown ; palpi and body beneath, and legs white ; 

 antennge blackish ; eyes reddish, hairy. 



Female. Upperside pale umber-brown. Foreioing with two blackish streaks 

 crossing the cell ; a sharply-defined transverse discal angulated series of outwardly 

 diffused broad whitish lunules, which merge into a less defined outer discal series, 

 and is followed by a submarginal series of slender whitish lunules ; a small black 

 ocellated submarginal spot between the lower medians. Hindiving crossed by a 

 similar but less defined inner and outer discal whitish lunular fascia, followed by a 

 submarginal series of more sharply-defined lunules, the upper ones of which
