the exception of vestalis, which will probably require a new

The species of Hepantheria, with few exceptions, are very 
complicated and difficult to identify correctly. Sir George 
Hampson has sunk a large number of species created by 
Monsieur Oberthiir in his monograph, but, in my opinion, 
in most cases has placed them as synonyms to wrong 
species. The forms of the cunigunda-bari group are espe- 
cially puzzling, and I believe the principal difficulty arises 
from the rapid and often very irregular fading of the wings 
and body. I have come to the conclusion that the specimens 
from the Guianas, Northern Brazil, and the Amazons are 
all one form and synonymous, while the South Brazilian 
specimens form a local race, and the two races must stand 
thus :—
