by Moore to be without the red costal streak, which in 
the female of edipodea is present.

Not uncommon in the low valleys and up to 5000 ft. 
during the rains. I cannot distinguish between what 
Moore figures as alexis and chromus. He says of the 
Ceylon alexis, ‘‘ Smaller than chromus, with broader and 
more prominently marked band on the under side of the 
hind wing.” I-have a large series of specimens, 
including two males and a female from Ceylon, one pair 
from Bangalore, four pairs from Sikkim, one male and 
two females from Andaman Islands, one pair from 
Shillong, one male from Barrackpur, and two males 
from Burmah ; but I find too much variation in the s1ze 
and in the band of the under side to allow me to separate 
two forms. De Nicéville considers them distinct, and 
says that alexis occurs only in South India and Ceylon. 
If, however, they are identical, alexis, being the older 
name, should be used; and, if they are distinct, the 
Sikkim form will bear the name of chromus.
