112) EUZOPHERA CEDRELLA and PHYCITA ABIETELLA. 
5. The length of time during which the moths are to be 
seen on the wing in the forest. 
6. The stage in which the insects pass through the 
winter. Is it the egg stage? 
7. The description of the larva of Z. cedrella and that 
of P. abietella, | 
Nore.—The above observations are required for each tree. With 
reference to No. 3, I recommend "that cones be cut up monthly from Apri 
onwards, and that the larve taken from each be carefully examined, described 
and then put into formalin, which will prevent their colours going, and 
sent to me to Dehra Dun. 
To ascertain No. 7 I recommend the following : Species of each of the 
different kinds of larvz should be put on to uninfected cones on convenient 
trees where they can be constantly watched—one on each cone, a descrip- 
tion of the larva in each case being first made. Each cone should be then » 
tied up in a muslin bag until about the end of July. It should then be cut 
off and placed in a small weoden box with alayer of moist earth at the 
bottom of it and the moth bred out. Inthis way it should be possible to 
definitely ascertain not only which are the larve belonging respectively to 
&. cedrella and P. abietella, and whether they have any other companions; 
but also which is the greater pest of the two.
