vessel. When full grown the larva is about half an inch in length. The speci- 

 mens which I collected pupated on June 2ndj and six moths of the above species 

 emerged on June 19th. The moth is a beautiful little creature, and varies con- 

 siderably in the colour of the fore- wings, some being of a pure shining white, 

 others decidedly pale yellow. This tortricid also feeds on basswood, oak and rose. 

 In 1899, I reared the species from Tilia americana, the moths emerging on the 

 15th of June. 



The Fall Cankeewoem was again abundant in the district, and at Chelsea, 

 Que., basswood trees particularly were attacked. On May 27th the larvae were 

 almost full-grown. On May 29th the caterpillars were reported to be stripping 

 apple trees near Hull.

The season of 1911 was not with me an insect year. It was remarkable for 

 some very hot spells, making in fact a record for heat in this neighbourhood. It 

 was also very dry in spring and early summer, these latter circumstances appar- 

 ently not being encouraging to most insects. 



Among the species most noticeable for their destructivenesis were the follow- 

 ing:— 



June-Bugs (Lachnostema fusca). These insects appeared in enormous num- 

 bers in early May, and though their destructive tendencies are practically over in 

 the perfect state the work of their grubs was very noticeable in the lawn. 



Cut Worms were very destructive, the larva of Peridroma saucia and Hadena 

 arctica and devastatrix being most in evidence. 



The Codling Moth (Carpocapsa pomonella) was very destructive, nearly all 

 early apples having been infested with them. This was not a good apple year and 

 1910 was still worse in this neighbourhood. 



The CuEEANT WoEM (Nematus ribesii) has been again very common. Most 

 people will not use Paris green on the bushes, for fear of bad results, but I find a 

 light solution perfectly harmless and very efficacious. 



I have not added much to my collection this year on account of the poor sea- 

 son and the pressure of business. I have, however, quite a few unnamed species of 

 Lepidoptera, which I should have liked to exhibit to the members, but circumstances 

 will again prevent my being with you.

During the past season I have been interested chiefly in the gall-producing 

 species of insects, and other points of entomological interest have been noted only 

 incidentally. 



In the year 1906 I found a willow in High Park, Toronto, riddled by the 

 Snout Beetle (Cryptorliynclius lapathi, L.). The same season this beetle was 

 reported from Beamsville and Eidgeway by Prof. Zavitz. These were the first 

 Canadian records for the species. Since their introduction these beetles appear to 

 have increased in numbers very rapidly, and have now become a serious menace 

 to our indigenous willows. During the past season a very large percentage of the 

 willows examined were found injured more or less by this beetle. The species of 

 willow mcst commonly attacked were Salix nigra and cordata. In a few cases 

 these beetles were found boring in Aspen poplar (Populus tremuloides) . 



In the same park where the work of the willow-boring beetle was first noted 

 clumps of Austrian Pine and Scotch Fir have been planted. These trees are being
