 curved beyond cell, thence somewhat inwardly curved to inner margin. 

 The spot on costa is considerably larger than the others and close to it 

 on outer side is another similar in shape and size, with some black scales 

 below it. A well-defined black terminal band evenly and neatly cut bv 

 pale at end of veins. Fringe slightly darkened. Hind wing soiled whitish
