be "according to Dyar's classification." This is misleading. The 

 essential part of that classification depends upon the homologies of the 

 tubercles, which I indicated by certain arbitrary numbers. Of course, 

 Mr. Hinds is at liberty to call tubercle ii.a of the thorax iv., or vii. of the 

 abdomen vi. + vii., etc., as in his figure, or make any other numbering, but 

 he will please not label the result " according to Dyar's classification," 

 which it is not. No one could homologize the description on page 187 

 with my writings without changing the numbers. Uniformity seems 

 desirable. Harrison G. Dyar, Washington, D. C. 



Not Surprised. 

 In reference to Mr. J. Alston Moffat's interesting account of the 

 emergence of a Telea polyphemus cocoon, in the October number, and his 

 query, " Is it double-brooded somewhere?" I would say that it is quite 

 possible in. localities and seasons. This year I caught a dark-coloured $ 

 specimen early in May, and near the end of August I found emerging 

 from a beautifully white and fresh-looking cocoon a light-coloured J . In 

 1898, I caught a large number of specimens at light throughout the 

 months of May and June, and early in September found five specimens, 

 two perfect, the other newly emerged, all resting on apple trees and 

 distinctly paler in colour than those of the early part of the season. It 

 struck me as remarkable, as I had seen no specimens flying during 

 August or September, and concluded they were belated in their 

 emergence. But on consideration it looks as if they were second broods, 

 so hastened or prematurely emerged from their pupa state that they had 

 not the strength and vitality of those that emerged in the proper season. 

 Although kept alive for some time before killing, their wings crinkled up 

 after being set, and made such unsatisfactory specimens for a collection 

 that I threw them out. I now think that in some seasons there is a 

 small second brood here, but so immature or weak that they do not fly.

THE NORTHWEST (CANADA) ENTOMOLOGICAL SOCIETY. 



The third annual meeting of this Society has been convened for 

 Saturday, November 9th, 1901, at 3 p. m., at Lacombe, Alberta, N.-W. T. 



(1) To review the past work of the Society. 



(2) To devise extension of the work. 



(3) To elect officers for 1902. 



This meeting will, we understand, be of unusual interest, as prizes 

 have been offered, two by Dr. James Fletcher, of Ottawa, and one by the 

 Society, for competition by the young folk of Lacombe district for the 

 best collections of insects of all orders, and the best of noxious and 

 beneficial insects. As there are a considerable number of Agricultural 

 Societies and farmers who are members of the N.-W. Entomological 

 Society, this competition is a step in the right direction. 



Mailed November Sth, 1901.
