260 CRYPHALUS MORINDA, MS. 

that at present never more than one pair of beetles have been 
found together in any one gallery, and it is therefore, I think, not 
improbable that the male pairs with but one female and is not 
polygamous. 
Locality from where reported. 
This insect was found by the writer inthe Spruce forest 
between Goara and Sarahan (Simla-Thibet Road) in the 
Bashahr State. 
Relations to the Forest. 
Very little is known about these small insects in India, and 
it is at present impossible to state what relation they really bear 
to the forests. I cannot at present say whether this beetle is 
abundant or not, nor whether it attacks young growth as well 
as old trees. It has only been found in the latter up to date. 
It is probable that it usually searches for branches which are 
weak in health, but examination of dead branches shows that 
those which it attacks in any numbers it invariably kills. The 
cambium is entirely eaten away and it is not unlikely that the 
larva is responsible for a good deal of the damage done. A 
certain thinning out of the smaller branches must take place 
on the tree under the attacks of this insect. 
Points in the life history requiring further observation 
1. How the larva feeds! Does it simply enlarge the 
elliptical chamber bored by the parents, or does it 
bore a gallery off this ? 
2. The number of generations in the year. If only one, 
the length of time spent feeding by the larve 
hatching out from the eggs laid by the June beetle 
and the time passed in the pupal stage. 
If more than one generation, their number, and the 
length of time spent by the different stages of the 
metamorphosis in each. 
3. The number of eggs laid by each beetle. 
4. In which stage is the winter passed through ?
