2 . Pale ochreous brown, sparingly dusted with fuscous. Fore 

 wings suffused with reddish on central area ; a white centred purplish 

 spot at end of cell ; antemedial line dusky, angled below costa, where 

 it is dotted with black ; postmedial line purplish brown, oblique from 

 apex to dorsum ; some purplish marks below apex ; subterminal line, 

 indicated by purplish dots, starts from costa before apex, curves 

 under oblique line, thence almost parallel with it to dorsum. Hind 

 wings have a purphsh spot at end of cell — this is centred with white 

 on the left wing, but not on the right wing ; postmedial line purplish 

 brown, appearing to be a continuation of the line on fore wings ; 

 traces of a dusky subterminal line. Under side similar to above, but 

 the postmedial lines are indistinct, and the subterminal lines are 

 indicated by black dots.

Collection number, 1606.
