 brown ; a white point at base ; slight blue-grey spots below costa

 which is slightly excurved to subraedian nervure, then slightly 

 incurved, a blue-grey spot on its outer edge below costa ; a blue- 

 grey discoidal spot; postmedial line dark, waved to below vein 4 

 and defined on each side by slight white marks at costa, then 

 by slight blue-grey marks to below vein 4, excurved below costa 

 and at middle, below vein 2 bent upwards to below end of cell 

 and forming an annulus, then sinuous to inner margin and with 

 small fiery red spots on it above and below vein 1, some white 

 points beyond it on costa ; the apical part of costal area with slight 

 blue-grey irroration and a small patch of whitish suffusion on 

 costa before apex ; faint traces of a waved dark subterminal line ; 

 a series of black points before termen with some whitish scales on
