 dorsum well before middle, across 3/4 of wing breadth, base extended 

 along edge of w4ng, top rounded; this top is connected by an almost 

 horizontal dark line with the following marking: a semicircular 

 band from costa beyond middle ascending to dorsum before tomus 

 and along tomus and termen to apex, dilated in tornus and in apex. 

 Cilia (rubbed) in tornus whitish with black basal third.
