 Fore wing with a short, dark, subbasal band bordered on the 

 outer side with white ; a dark oblique band from costa towards 

 tornal angle, also bordered on the outer side with white, 

 reaching R 3 . Hind wing : the blackish -brown border less 

 sharply defined than in himachala, strongly broadened at 

 costa where its inner margin reaches the proximal end of the 

 apical lobe ; apical lobe ashy-bluish, bordered black proxi- 

 mally. Underside : fore wing dark brown as far as the post- 

 discal line at inner angle, the postmedian line thin, brownish- 

 yellow in fresh specimens and ivory-yellow in old ones. Hind 

 wing ashy greyish -brown, anal area pale straw-colour. Distal 

 margin of fore wing more deeply emarginate under R 1 than in

 tornal angle ; costa of hind wing deeply emarginate. Length 

 of fore wing 19' 5 mm. ; width of fore wing 7*3 mm.

 in S. China, where the moth appears to be fairly common from 

 July to October on grassy slopes at an elevation of about 

 2,000 to 2,400 feet.
