Forty-first Annual Report of the Entomological 

 Society of Ontario, 1910: 124 pp., 23 figs., 2 pis. Pub- 

 lished by the Ontario Department of Agriculture, Toronto, 

 1911. 



Founded as this Society was "for the investigation of the 

 characters and habits of insects, the improvement of ento- 

 mological science and more specially its practical bearing on the 

 agricultural and horticultural interests of the Province" these 

 annual reports have assumed since . their genesis a double 

 function, namely, the recording of entomological investigations 

 complete or in progress and cf scientific data, and also the dis- 

 cussion of the economic bearing of these investigations and their 

 practical application. While it would appear to the outsider 

 to be confined to "the interests of the Province," this is far 

 from being the case. Not only does it include in its membership 

 entomologists from all of the provinces of Canada, but the 

 activity of its members displays its really national character. 

 There is naturally a distinct overweight in favour of the older 

 provinces which, it is hoped, time will ccrrect. 



The present report does not differ materially from former 

 ones, containing as it dees much of interest and value to the 

 amateur entomologist, the scientific worker and to the practical 

 farmer, fruit-grower and forester. In the first thirty pages the 

 insects of economic importance which have been noticeable 

 during the year (1910) are described by various members of the 

 Society, the report of the insects of the Ottawa district, by Mr. 

 Arthur "Gibson, will be of interest to members of the Ottawa 

 Field-Naturalists' Club; Mr. L. Caesar refers to the insects of 

 the year in Ontario. "Beetles found about Foliage" is a pleas- 

 ing account of sylvan entomology, by Mr. F. J. A. Morris, and 

 Dr. Fyles' account of "The Pool " reveals that veteran naturalist 

 and observer at his best. The attraction which entomology has 

 for the botanist is shown by Mr. J. E. Howitt's observations on 

 the Bean Maggot. Mr. Norman Criddle's observations on the 

 migration of locusts in Manitoba are a useful addition to a 

 knowledge of our native species. Prof. T. D. Jarvis makes two 

 contributions, the first being a most useful paper on the Coeeidae
