the Lepidoptera of the Khasia Hills. 309 
below the apex, decreasing in size hindward, and ex- 
tending only to the first median interspace; sometimes 
an indication of a lunule in the interno-median inter- 
space; the female has also a lunulated marginal border, 
broader than in the male, and extending in a thin line 
to the hinder margin; it is probably a seasonal form of 
pyranthe.

Generally smaller than either of the two preceding ; 
the male usually with no black border, never with more 
than an indication of it; the female with a pale border, 
very narrow and lunulate; this may also be a seasonal 
variety of pyranthe; but I have in my museum long 
series of all three, and each appears to be very constant 
in these characters.
