In May tgot I was able to inspect some Blue pine which 
had been felled outright in June 1900 and left with the bark on. 
The bark was now quite dry. These trees were not noticed 
to have been attacked at the time of felling but examination 
showed that they had been badly infested by the July beetles, 
and perhaps by the later generations. The greatest number 
reared, however, was not more than two life cycles. 
My recommendations for future treatment, with the object of 
reducing the numbers of these oeetles in the forests and pre- 
venting further spread from the infested centres, an occurrence 
which is undoubtedly taking place, areas follows:— , 
1. That in future, vhen it is considered necessary to 
remove the Blue pine or Spruce from around the 
Deodar, the former trees should not be girdled but 
felled outright and at once barked and the inside 
of the bark exposed to the sun’s rays, 
2, That all still green girdled standing trees be treated in 
this way, 
3. The trees should be barked during the second or third 
week in May, the beginning of July, the middle or 
third week in August, and the beginning of Octo- 
ber. The reason for this is that the larve will 
then be still young and may be killed by the drying 
up of the bark, Since, however, the generations 
overlap (owing to the first laid eggs developing 
sooner than those deposited at later dates), there 
will certainly be either pupz or beetles which will 
| not be affected, and these will issue in due course. 
4. There will be no harm in felling the trees at earlier 
dates, provided the barking is done at the periods 
specified. 
5. That both girdling and topping trees should be dise 
continued, 7 
6. At all infested centres I recommend that a 
system of “trap trees’’ be prepared, For this 
purpose sickly trees, suppressed trees, ete
