180 THE CANADIAN ENTOMOLOGIST. 



form, not a banded one amongst them — that form was abundant on the 

 bushes at the time. There were still about half a dozen to mature when I 

 left, but some of them were sufficiently advanced to give indications 

 through the pupa skin what they were to be. On re-reading Mr. 

 Coquillett's article in the May number of the Canadian Entomologist, 

 I was quite startled on finding that he says his pupa was suspended by 

 the hind end of its body ; for the result of my observation was to leave 

 the impression strong on my mind that they were suspended by the head, 

 and I did not think it strange that they were, or that anyone had thought 

 differently. My impression of the tinge of color through the pupa skin is 

 that the yellow w as up, and on one visit there was one that seemed as if 

 the pupa skin had just burst on the back and left the insect exposed in 

 exactly the position it was before it burst, and I was struck with the 

 exact resemblance in form and size, even to the pupa on either side of it. 

 But is not this the usual position for Coleopterous larvae to suspend ?

[We think that when our valued correspondent has an opportunity of 

 examining pupae of this insect more carefully, that he will find that they are 

 suspended by the head downwards, as in the case of the Coccineliidie. —

Having occasion lately to refer to some back numbers of the Proceed- 

 ings of the Boston Natural History Society, my eye accidentally fell on a 

 paper by Professor Alexander Winqhell, read before the Michigan Scientific 

 Association on June 24th, 1863, and entitled, "Notes on Selandria 

 cerasi, Harris, as it occurs at Ann Arbor, Michigan." (p. 325.) 



Glancing over the paper, I saw the following passage: "As to the 

 remedy for this horticultural pest, it may be added to what has been 

 already published that the odor of coal-tar effectually drives away the fly. 

 This can be smeared over a board and suspended in the tree, a resort 

 which I have found effectual against the plum-weevil." 



Can you or any of your readers tell me if this alleged means of driving 

 off Cenotrachelus nenuphar has really an}^ virtue ? I never recollect see- 

 ing the plan suggested before this. Yours faithfully, 



E. W. Claypole.
