262 CRYPHALUS BOSWELLILA, MS. 
stages of its life is to be found at the beginning of the month. 
In branches of the Boswellia which appeared to be dying but 
were still green larvz were plentiful and also pupz and light- 
coloured beetles, the latter not quite mature. The larve are | 
to be found in irregular-shaped cavities in the bast and sap- 
wood which usually contain a certain amount of moist wood- 
dust. Inthe pupal and beetle stages this latter becomes dry. In 
other branches darker coloured beetles were present, and these 
were apparently the mature beetles of this generation which had 
already begun egg-laying. The @ and 2 beetles were found 
together gnawing out irregular-shaped chambers beneath the 
bark in the bast and sapwood. These beetles had apparently 
only just matured and had at once commenced egg-laying, the 
eggs being those of a second or third (?) generation. 
This is all that has been at present observed about this 
insect. 
Locality from where reported. 
This beetle was found in the Bhamburda reserve near Poona 
in the Bombay Presidency. 
Relations to the lorest. 
The smaller green branches of Boswellia serrata are bored 
into by the insect for the purpose of laying its eggs in them. 
The larvae on hatching out feed upon the surrounding cambium 
layerand destroy it. If at all plentiful, the bark is eaten right 
round and the twig, being girdled, dies, 
Further observation is required to ascertain whether the 
insect is at all numerous and whether it infests young plants. 
In this latter case it might on occasions become a serious pest. 
Points in the life history reguiring further observation. 
1 The number of generations passed through by the 
insect in the year. This is important, If more 
than one, we require to know the length of time 
spent in the various stages of the metamorphosis 
in each generation. 
2. Does the insect attack young plants ? 
3. Where does it pass the cold-weather months ?
