 line, outbent from subcostal, suffusing at vein 4 with a similar postmedial 

 line inbent from costal edge, the space between forming a triangular whitish 

 yellow spot; below vein 4 the two lines suffuse into a thicker vertical line to

 traces of a fuscous postmedial line, more distinct at costa and inner margin. 

 Fore wings below much paler, the cell and inner margin whitish; a black

 to inner margin. Hind wings with a dark point on discocellular; postmedial
