 It will be noied thai in looi no ooUectino- was done in Ma\', and it is the 

 writers impression that the insect was not \ery abundant, as was the case in 

 ux">.:, in that locality prior to the bej^innin^ of our operations. A stuily 

 of this recoi"d shows that the beetles were more abundant from the 13th 

 to the j^orh of Ju.h\ and from the oth to the latter part of August. The 

 tenJ.encv of this insect to breed more or less throui^hout the season is also 

 indicated bv the condition of a badly infested twio-. received by the writer 

 the last of Auci'-^t loor. Fhis small piece, about 3 inches long, was almost 

 honeycombed bv the insect and containeii numerous pupal cells in each 

 of which there was a j-iupa in a nu>rc or less advanced stage of develo}> 

 ment. One insect had emerged in transit, another orie was almost ready to 

 apv'^oar ar.d the remainder would probably have forsaken their retreats 

 before the approach of cold, weather. It is interesting in this connection to 

 note that Or Hopkins found pupae in spruce bark June J 7, and in while 

 pine July 15, in vellow pine July 11, showing that some of the insects must 

 develop later than early May. The later captures represent scattering- 

 individuals, and it would appear as though this insect bred more or less 

 throughout the se.\son. though, as stated by the later writers, the principal 

 brood mav appear in May and early June. 



Food plants. Fhis weevil is well known as a serious enemy to most of 

 our native pines and severe injury to spruces has been recorded by several 

 writers. 



Natural enemies. Dr Fitch has stated tliat after the infested shoot 

 becomes withered and drv in midsummer one may observe that the bark 

 covering the cells has been broken and peeled oil" in spots and that all its 

 lower parts are torn awav. Newly perforated holes larger than the bur- 

 rows of this insect may be obser\ed. here and there, in the wood. These, 

 he states, ore the work of small birds which are ver\- efficient in devouring 

 the lar\\\e ,uid the pupae of this pest. Dr Riley in his report for 1SS5 

 states that the grubs or larvae are exposed to many dangers from camiv-
