Part III.] Stebbing and James : On the Bark-horing Beetles of Zhob. 249 
exude. When Mr. Stebbing came to visit the forest, the drought had 
been severe and the pests were fast getting the upper hand. If the 
drought had continued, I have little doubt that the whole of the forest 
would have been killed off by the insects as predicted by Mr. Stebbing. 
But both last year and this there has been a good rainfall, with the result 
that the trees have regained their sap and vitality and are now able 
to resist the enemy should they not have been already attacked. 
‘ ‘ However, I am confident that the resisting powers of the trees them- 
selves and this year’s campaign have almost exterminated the insects. 
Should next season be favourable they should disappear entirely. If 
not, I would strongly recommend that the trees be frequently inspected 
during the summer months and when a new one is attacked it should be 
at once treated with kerosine oil and tar. 
“ I repeatedly tried to get those owners of the Chilgoza trees who had 
not emigrated to Independent Territory to themselves co-operate with 
the Forest Staff and help in the campaign against the pest. But I failed 
to enlist their help without payment. I even held out hopes to t hem that 
their grazing rights would be restored should they co-operate with- 
out payment, but they were obdurate. The reason for their disinclin- 
ation in the matter was that only a small number of actual owners of 
tiees were present. The majority had emigrated when the bulk of the 
Arozais went across the border and the minority did not feel inclined to 
take upon themselves the responsibilities and work of the majority. 
Again, the short time that the Political Agent is at Shinghar is a time of 
golden harvest to this minority. There is plenty of demand for labour 
for building purposes, and forage and supplies are brou. ht in, for all of 
which they are handsomely paid. They, therefore, did not feel inclined 
to forego the certain profits to be made, and give their services free in a 
cause in which they had not much faith or sympathy. I was therefore 
constrained finally to employ the local people on a daily wage to carry 
out the systematic eradication of the insects. 
“ Altogether, as stated above, 1,643 acres of forest were gone over ; 
out of this 54 trees were treated with coal tar and kerosine oil and 217 
were burned. The expenditure incurred in this treatment, including ex- 
periments, was Rs. 130-12-5. 
“ Mr. Stebbing, in his book, mentions three varieties of Boring Beetle at 
Shinghar, viz., Polygraphus Trenchi, Phlceosinus and Pityogenes con- 
ifercB. This season, I believe, a fourth species not mentioned by Mr 
Stebbing, has been discovered. The (larva) beetle is much longer and 
thicker than the other species, being about | to f " in leng< h without its 
antennse and of a dark brown colour. I secured two specimens of 
both beetle and larvae, which have been sent to the Forest Fxtra Assist- 
ant Conservator. He has been asked to give any information about them
