Life History. 
The éggs are laid some time during July, but it has not yet 
been reported where they are deposited. 
The caterpillars are to be found on the trees they attack all 
through August, feeding upon the leaves of the food-plant, To- 
wards the end of the month they spin a rough hairy cocoon and 
change into the pupal state inside it. They remain in this 
stage until the following July, the moths hatching out at the 
beginning of the month. Some pupz collected in October and 
made over to me in December hatched out at Dehra Dun,! 
towards the latter part of May .This proves that in Jaunsar the 
insect has but one generation in the year, the earlier date at 
which my pup issued being accounted for by the fact that 
they were kept in a warmer place throughout the winter. 
Localities from which reported. 
The insect has been reported as doing considerable defoliat- 
ing damage in the Jaunsar forests of the North-West Hima- 
layas. Hampson gives the habitat of this moth as Japan, North- 
West Himalayas, Punjab, and Rangoon, so it has a wide dis- 
tribution and has other food-plants besides the ones mentioned 
below. 
FReelations to the Forest. 
A. anedina has proved itself a serious pest to the horse 
chestnut (Zstulus indica, Colebr.).. It swarms all over the 
trees, entirely defoliating them in bad seasons. In 188g by the 
end of August the trees were all leafless and the insect appeared 
to be equally abundant the following year. The hill tun tree

They were brought down and made over to me at Chittagong in Eastern | 
Bengal, and the weeks spent in this much warmer climate doubiless led to 
their issuing earlier,
