-Lymantriide are hairy, being generally clothed with very thick 
hair or with thick tufts of hair. 
The pupz are described as being formed within cocoons, the 
latter consisting of the caterpillar’s hairs fastened with a very 
small quantity of silk. 
I have taken these four moths together since no data are at 
present available as to which larva is the most abundant and 
their descriptions are still required. 
Life History} 
The caterpillars probably make their appearance some time 
during the latter part of August, since the defoliation of the 
Mairaghat Forest was observed to be complete about the middle 
of September. 
Some larva: were collected on 22nd September and placed 
in a box under observation. On the 4th October pupation 
commenced, both amongst the caterpillars inthe box and gene- 
rally amongst those in the forest, the caterpillars being full-fed 
about the end of September. 
Caterpillars were, however, to be found in small numbers in 
the forest after October 4th. 
The insect remained in the pupal stage for about nine 
days, the first moths emerging on the 13th October. From the 
above descriptions of the latter it will be noticed that the 
females are generally larger than the males. 
Eggs were laid by the females in about two days after 
fertilisation which took place almost as soon as they had left 
the cocoon and become fully developed. After egg laying the 
female moths died. 
This is at present all we know about these life histories. 
Iam of opinion that it will probably be found that this Septem- 

1The specimens of these insects were sent to me in December 1899 be 
Sir H. A. Farrington, Bart., from the Jalpaiguri forests, Bengal, of which 
he was incharge. The notes on the life histery which he sent me were, he 
says, drawn up by his Range Officer Babu L. R. Sen. No observations were 
made before the middle of September as the Ranger was away on leave till 
then, and Sir ao), did not visit that portion of his division till October. 
On the Ranger's return he found the sal trees in his range leafless, the 
defoliation being due to caterpillars of the above described moths.
