at a point, R' not stalked, M* well stalked; pale green, with 
costal edge narrowly reddish; a very minute dark cell-dot ; 
distal border variegated, light red and more purple-red, the 
latter shade prevailing proximally, its proximal edge olive- 
brown, commencing at costa close to apex, forming (except 
for slight indentations at the veins, that at SC° the most 
noticeable) a fairly regular-curve to the middie of M’, running 
inward for a short distance along M"', then approximately 
vertical (slightly curved) to hind margin ; a dark terminal 
line, interrupted at the veins ; fringe reddish, with a yellower 
line at base. | 
Hind wing elongate, with strong toothed projection at end
