18 THE EEPOET OF THE Ao. 36 



I 



of a felled oak. From the" latter date till August 7 were found some specimens 

 of Leptostylus resorting to a pjle of oak billets at the same spot; they appeared 

 to be about to oviposit between the bark and the wood at the ends of the billets, 

 probably attracted by the smell of fermenting sap. Two species of Oherea were 

 captured between June 26 and July 13, one feeding in dogwood blossom, the other 

 resting on raspberry foliage. About raspberry foliage, too, as well as about bass- 

 wood leaves there were more specimens of Agrilus than usual seen, mostly of two 

 species, ruficollis and anxius. 



Among Hymenoptera, the Horn-tails seem to have been active on the young 

 elms bordering some of our residential streets; I found in October as many as 

 three females of Tremex columha imprisoned in the bark of one young elm.

The season of 1910 was again, like 1909, very cold and late in spring, the 

 warmest weather 73° in the shade occurred in March, in which month the tempera- 

 ture was over 70° on three different occasions (though we did not have much warm 

 weather until near the middle of June), and several species of moths were taken by 

 me at light in March, an unusual occurrence here. 



Injurious insects were not remarkably plentiful. Complaints were made of the 

 turnip-root maggot, in fact late sown turnips were almost a failure from the 

 depredations of this insect. The Easfberry Cane-Girdler {Oherea himaculata) 

 was noticeably abundant; in some gardens the broken tops of the canes looked 

 as if someone had been going through the patch with a stick. The apple crop was 

 almost a failure here; I have reason to suppose that it was caused by the very 

 wet weather Miich occurred during the time the trees were in blossom, and in 

 consequence the bees had no chance to carry the pollen for fertilization. Carpocapsa 

 pomonella should be rare next year if scarcity of food lessens their numbers. 



Canker Worms were very common here this spring; the moth of these and 

 of Erannis Uliaria are in great numbers around my lamp as I write this, October 25. 



Nematus rihesii, the Currant Worm, was very prevalent, and the first brood 

 coming in the wet season of this year made it almost impossible to keep any in- 

 secticide on the plants long enough to check their ravages. 



On a hedge of hawthorn a species of Sohizoneura was so plentiful that the 

 trees appeared as if they had been whitewashed. On examination it closely re- 

 sembled the alder louse, on which Feniseca tarquinius feeds. 



During a wind storm in July a large quantity of maple trees, or large limbs 

 of the same, were broken. This occurred particularly in two or three localities 

 where the trees were full of the burrows of the Pigeon Tremex {Tremex columha), 

 and many of the grubs and even parts of the perfect insect were present; tliere 

 seemed to be no other reason for their rotten appearance except what might be 

 from heavy top pruning. I have taken some moths this season which are rare to 

 me, viz., Fentonia martesia, Elida caniplaga, Notodonta simplaria, Flusick 

 oxygramma, Syneda Alleni, etc. 



Division No. 6, Galt District — E. S. Hamilton. 



The weather conditions in this district during the past spring and summer 

 have not been favourable for insect life, and as a consequence fruit growers, 

 nurserymen and the farming community in general have had little to contend 

 against in the way of insect pests.
