40 THE EEPORT OF THE No. 36 



The chief injury from the standpoint of the forester will likely be to the 

 poplars and especially the Carolina Poplar. 



The President: Perhaps Mr. Swaine would like to make a few remarks in 

 this connection, 



Mr. Swaine: Mr. Chairman, I have had very little opportunity to study 

 this beetle in Canada. Some years ago in Ithaca it was very common in the 

 basket willow in the plantations there and did considerable damage. In Canada 

 I have found it only near Ste. Anne's and it was there in the common scrub willows 

 and not very abundant. I have not had it sent in in the last three or four years 

 in any numbers from any part of Canada except Ontario and southern Quebec, 

 and very few reports have been received. Mr. Caesar's account was very interest- 

 ing, indeed; the life-history is just as I remember it on the different occasions 

 I have studied it, and the control measures usually given are not very effective; 

 it is a very difficult matter to control this beetle. On the smaller willows no 

 special effort to save any particular tree is worth while and the destruction of 

 the infested trees is perhaps the only effective method. Only a few of the willows 

 that are affected are worth saving. 



Mr. Winn: Professor Caesar mentions the keeping of the beetle alive on 

 apple or peach. I may say he very kindly sent me ten specimens of the beetle 

 to show what it looked like in order that I might recognize it if I ever found it 

 alive. After a couple of days I turned the specimens out on a blotting pad and 

 pinned two or three, then noticed that instead of there being ten there were only 

 nine. The tenth was still alive and had crawled away. This I secured and 

 placed in a tin box and after again taking it out three weeks later, apparently 

 dead, it recovered. This, shows how long the insect can live without food being 

 given it, and how dangerous the insect might be when capable of living through 

 a like shortage under natural conditions. 



Prof. Caesar : One of the points that I would like very much to get informa- 

 tion on is whether any person has found the adults of this beetle in the spring. 

 It seems to be taken for granted in the U. S. literature on this pest that it does not 

 pass the winter as an adult, and that there are no eggs laid in the spring, but 

 the fact that we could find a considerable number of them in nurseries suggests 

 that egg-laying in the spring is very probable. 



Mr. Swaine: The specimens that I took at Ste. Anne's were, I think, all 

 taken in the fall. This is some years ago, so I am not quite certain on this point, 

 but believe that they were taken in the fall. 



The President: I have no doubt that if any of the members get further 

 information in regard to this beetle hibernating in the adult form they will advise 

 Professor Caesar of the fact, and we will now proceed to the next paper. 



Dr. Felt's paper was read by Mr. Gibson. 



SIDE INJURY AND CODLING MOTH.^ 



E. P. Felt, Albany, N.Y. 



This type of injury has been unusually abundant in the western part of New 

 York State for the past four years. It appears to have been figured and des- 

 cribed first by John W. Lloyd" in 1907 (Bui. 114, 111. Agr. Exp't Sta.). He, 

 however, attributed the damage to the work of the second brood.
