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; 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 SC 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 
area.

blackish above. Abdomen above mostly blackish, beneath 
white. 
Fore wing in anterior and distal part blackish brown, 
posteriorly to the cell and beyond white, the white area being 
bounded from about the origin of M’ to anal angle by a fairly 
regular curve; the blackish area irrorated with white in 
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 R? nearly to SC°; the white area slightly dusted with 
blackish near base. 
Hind 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 
and gradually broadening between these points and apically. 
Underside similar, but with the dark brown areas all 
irrorated with white and with the costal edge of hind wing 
dark-speckled.
