by a thick, slightly curved mark from near costa about to R^ ; 

 some small dark spots near termen ; elongate dark terminal , 

 marks at vein-ends; fringe weakly dark-spotted. 



Hind wing without distorted venation j white, densely 

 irrorated with blackish, but with a broad elongate clear patch 

 in middle from base to at least three-fourths, bounded ante- 

 riorly by SO and R^, posteriorly by SM and M\ somewhat 

 rounded at its end ; a clear apical patch. 



Underside similar, but with the entire posterior region of 

 the fore wing smoky, the abdominal margin of the hind wing 

 for a width of 2 mm. mostly white, with dark irroration and 

 with some dark interruption about R^ and the submedian

 proximal half and containing two large white spots distally, 

 one from costa to R\ broadest (4 mm.) at costa, its proximal 

 edge reaching middle of costa, the other smaller, more distal, 

 from R2 nearly to SC^ ; the white area slightly dusted with 

 blackish near base. 



Bind wing without distorted venation ; white, slightly 

 dusted with blackish brown near base and with a narrow 

 distal border, narrowest about R^-R^ and at tornus, slightly
