 one-fonrth to nearly the middle of inner margin, projecting in cell, thence sinuous ; 

 outer line from five-sixths of costa, angled outwards on vein 7, then oblique and 

 slightly sinuous to three-fourths of inner margin ; a dark irregularly dentate 

 snbmarginal line, the space between it and outer line slightly paler than the rest 

 of wing ; fringe concolorous ; cell-spot obscure, blackish.

 subapical patch, oblique inwards, dentate-Iuuulate, to two-thirds of inner margin, 

 before which it curves outward ; snbmarginal line from the outer end of the 

 subajjical patch, also dentate-lunnlate, and nearly parallel to outer line ; a ditfuse 

 dark curved median shade closely approaching outer line below middle ; the whole
