Forewing long, narrovr, costa slightly arched towards the end, apex acute, 

 exterior margin oblique, slightly convex, posterior margin recurved ; cell long, 

 narrow; first subcostal emitted at one-half before end of the cell, second at one- 

 fifth, trifid, fifth from end of the cell ; discocellular obliquely concave, radials from 

 upper and lower end ; middle median from angle close to end of the cell, lower at 

 one-third before the end ; submedian much curved from the base : hind wing short, 

 broad, exterior margin convex ; cell less than half length of the wing ; discocellular 

 slightly bent in the middle, radial from lower end ; two upper medians from end of 

 the cell, lower at one-third ; submedian and internal vein slightly recurved. Body 

 moderately stout; palpi porrect, second joint roughly squamose, reaching half length

Forewing with a dark purplish-brown band extending along the costal border 

 from the base to the apex, the area from the band to posterior margin being pale 

 purplish brownish-grey and almost greyish-white along the lower border of the costal 

 band ; the lower area of the wing is also crossed by a basal, a subbasal, a medial, two 

 discal, and a submarginal grey-bordered dark brown lunular line, followed by a 

 marginal row of similar coloured linear spots ; a dark brown spot also situated below 

 the cell : hiudwing dark purplish-brown, almost black externally, the discal area and 

 below the cell more or less semitransparent and crossed by the dark veins. Thorax 

 dark purplish-brown, abdomen blackish ; palpi, and legs dark purplish-brown.

 sixth, trifid, third at one-fourth from base of second, and fourth at one-half from base 

 of third ; fifth from end of the cell and joined to third for a short distance beyond 

 its base ; discocellular obliquely concave, slender, radials from upper and lower end ; 

 middle median from close to end of the cell, lower at one-fourth ; submedian much 

 recurved from the base : hindwing broad ; apex very convex, exterior margin mucli
