Life-Htstory, 
The moth appears on the wing during the first fortnight tc 
three weeks of July, and was very abundant in 1902. © 
The larva feeds upon the Kharshu oak and spins itself up 
into a leaf to pupate, at about the beginning of July. Pupation 
lasts about 8 days. os 
' Pupz were obtained from the leaves of the tree in the second 
week of the month; but no moths were bred from larva, so it 
is not certain as to which of the several Tortrix larve present 
on the trees changes into this moth, It must have played a 
large part in the very heavy defoliation the trees underwent 
as the moths were very plentiful, fying around the oak trees 
‘both during the day and night. 
Locality from where reported, 
This insect was found plentifully in the oak forests at 
Deoban, North-West Himalayas, in July 1902. Elevation, 9,500
