The species differs from 8, lwteola, Swinhoe, in the paler 
ground colour of the primaries and in the second trans- 
verse line of these wings being angulated. 
It is variable in the colour of the primaries, which ranges 
from pale whitish ochreous to pale reddish ochreous on the 
one hand and to luteous-grey on the other. 
Alphéraky describes this species from the province of 
Aindo, Central Asia. It appears to have occurred in June 
and July in most of the localities in Western China that 
my collectors visited.
