Life-History. . 
1 know little about this insect. It was bred out of some 
leaves in the breeding-box from which the AMeteones sp. 
parasitic fly mentioned above was obtained. It was either in 
its minute caterpillar or pupa stage in the second weekin July 
amongst the Kharshu leaves, and the moth issued soon after the 
middle of the month, 
Relations to the Forest, 
The larve of these small moths are all defoliators and were 
heavily defoliating the Kharshu oak in the Jaunsar Division in 
June-July 1902. They work together or almost so, some appa- 
rently maturing slightly before their companions, and the trees 
rapidly become leafless under their attacks, So numer- 
ous were the caterpillars that their droppings could be heard 
pattering down like a shower of rain. There can be little 
doubt that this heavy defoliation must havea serious effect upon 
the vitality of the trees, and it is extremely probable that it ad- 
versely affects the maturing power of the seed and consequently 
of the regeneration of thistree. These smaller caterpillars were 
more numerous upon the trees than their Noctuid companions. 
Points in the life-history requiring further observation, 
1. Where the eggs are laid, Is it in the axils of the 
buds?
