106 THE REPOET OF THE No. 36 



Mr. Swaine : Yes, especially when mixed with yellow pine. 



Peof. Zavitz: I was very much interested in Mr. Swaine's reference to the 

 turning of logs in the booms. This work can be of great economic value to the 

 lumbermen in our northern country, because I have known lumbermen to get gangs 

 of men and put them on the booms all summer to turn the logs, and when they 

 get such scientific information they will turn their logs less frequently. 



Mr. Winn : Does the Locust Borer resort to other flowers to any extent besides 

 the goldenrod? 



Mr. Swaine : "We have found it only on the goldenrod. We have a nice patch 

 of goldenrod a short distance away from our block of locust trees, and we get the 

 beetles flying back and forth between the flowers and the trees. 



Mr. Winn : Some people built a house along side of mine, where I had a very 

 fine patch of goldenrod, and the nearest place where they came from, and I cannot 

 find them on any other flowers at all that were apparently equally attractive. I 

 have never been able to see the beetles on the locust trees, but do not get a chance 

 to go up in the daytime. 



Mr. Dearness : Why is the brush useful against the Monohamnus beetles ? 



Mr. Swaine : It is because of the shade they provide. The beetles love the 

 sunlight. We often see them on a fallen tree lying in the sunlight, but with a 

 portion in the shade: the mating beetles will be found invariably upon the sunny 

 end, and the shaded end will accordingly have few or no eggs laid upon it. 



Prof. Zavitz: I had a very interesting experience in that connection at one 

 time. One summer in collecting I noticed a" tree had fallen from the dense woods 

 out into the road, and I used to go to that tree during June and along early in 

 July, where numerous s-rpecimens were to be found just outside the fence where 

 the tree was in the sunshine, but in the shade I never found a specimen. 



Mr. Swaine : It is a very convenient habit for we can use our knowledge of it 

 in protecting logs which have to be left in the woods. 



Mr. Dearness : Does the temperature have anything to do with the hatching ? 



Me. Swaine: I do not think the females would go into the dense shade to 

 oviposit at all. 



Mr. Harrington: I think most of the Cerambycidse prefer to oviposit in the 

 sunlight. 



NOTES ON" SOME INSECTS OF THE SEASON. 



L. Caesar, 0. A. C, Guelph. 



It may be worth mentioning that in the Niagara district at least, and appar- 

 ently in most other parts of the Province, there was a wonderful diminution in the 

 number of most kinds of insects this year, compared with the average season. This 

 may have been due to the abnormally wet May and June destroying the immature 

 stages. 



The Clover-hay Moth (Hypsopygia (Pyrdlis) costalis). 



This year for the first time I found the work of this moth on a large scale on 

 July 13th, at Wellington, Prince Edward County. Pea straw from the canning 

 factory had been dried and stored in an open shed some two or more years ago, and 

 in this the insect had bred. At the time of my visit most of the adults had 

 emerged, though there were still a good many pupa3 and a few larvae. The moths
