 inner line, and over the outer third of wing; first line from 

 one fourth of costa to near the middle of inner margin, broader 

 above ; a deep brown spot at end of cell ; second line from 

 shortly before apex to inner margin shortly before anal angle, 

 bent outwards in middle, edged inwardly with deeper velvety

 marginal area dull brown, with steely reflection along the 

 hind margin ; fringe deep coppery brown, with a lustrous 

 tinge. Hind wings olive-ochreous, tinged with darker olive ; 

 central area from near base to hind margin occupied by a dull 

 fuscous elongated triangle, containing towards hind margin 

 two broad brown bars, separated and preceded by steely scales ; 

 fringe like fore wings from apex to elbow, thence olive- 

 fuscous like the inner margin. Abdomen ochreous, suffused 

 with dark fuscous ; head, thorax, face, and palpi dark purple- 

 brown with lustrous reflections. Underside of both wings
