 strongly inwards-oblique; a large, dark fuscous, subquadrate patch 

 at base of wing, somewhat extended over base of dorsum, along ex- 

 treme base of wing continued by a fuscous suffusion to costa, posterior 

 extremity of patch moderately pointed, in fold; stigma rather large, 

 rounded, equal, slightly suffused; first discal beyond middle of cell, 

 second discal on closing vein, plical, its width beyond first discal; 

 three very irregular bands of fuscous dusting across wing at middle, 

 connecting second costal dot, stigmata and dorsum; beyond cell, 

 connecting third costal dot with second discal stigma and this with 

 tornus, so as to form a more defined and darker spot halfway between 

 them, and a cloudy, sinuate band from posterior part of third costal 

 spot, parallel to edge of wing, to dorsum before tornus; a series of 

 small dots on ends of veins lc-8, partly interconnected by a fine 

 marginal line. Cilia pale ochreous, with a light fuscous subbasal 

 band 



Hindwing glossy ochreous whitish, towards apex with the faintest
