In the majority of specimens there is a well-defined sexual brand on the 
primaries of the male, but in others this is very indistinct, whilst in a few, 
equally fine in condition, there is no trace of the brand. This is one of 
many similar instances occurring among Chinese Lepidoptera, which tend to 
shoAv the um'eliable nature of secondary sexual characters when used solely 
as a basis for specific or generic subdivision. 
The female is rounder in the wing, the basal two thirds of all the wings 
are of the male colour, limited on the primaries by a dark straight band, and 
on the secondaries by an angulated band as in the male, the outer third of all 
the wings conspicuously paler. 
Occurs throughout China from Ningpo to Moupin.
