212 SCOLYTUS MINOR, MS. 

these and other deodar areas and all attacked trees be treated 
as above detailed. 
I inspected some fellings being made in the forests round 
Pajidhar and found that large trees cut in the spring, z.¢., in May, 
were covered from head to foot with the borings of this and the 
larger Sco/yéus beetle. Both main bole and all the branches 
were infested with the pests andin every case the galleries 
contained full grown larve. In other words, the trees as soon 
as felled had been attacked by a swarm of the Sco/ytus beetles. 
In a further note on the Scolytus major | have given a 
rough calculation, from measurements and countings made, of 
what this means in increase of beetles per tree per year 
(see p. 205). 
If it be possible, [ recommend that in future all deodar trees 
felled between the middle of April and middle of August should 
be at once barked. Exposing the bark to the sun’s rays will be 
sufficient to kill all larvee and pupe present. A standing order 
that all deodar trees felled are to be immediately barked 
will be the simplest means of putting an end to this aid tothe 
ncrease of these beetles. 
2. All infested young saplings should at once be cut out and 
barked or burnt. 
Points tn the life history requtring further observation. 
1, The number of generations in the year. This is a most 
important point. It probably varies with the eleva- 
tion. 
2. The length of time spent in the various stages of the 
metamorphosis of the succeeding generations, 
3. In what stage and where the insect hibernates through 
the winter.
