escape, and their unprotectedness would be transmitted to and 

 accentuated in subsequent broods. Thus, when the selective agency 

 again became active, the race would be exceptionally vulnerable to 

 its attacks, and the species would be nearly exterminated until it was 

 gradually selected up to the average of its protective potentiahty, and 

 its normal numbers so re-established. — S. J. Bell, Hon. Sec.

 Mr. Burr asks for criticisms of this scheme of classification.

4. Beport of the Entomological Society of Ontario, 1908. Toronto. 



1909. 

 This report of one hundred and fifty-two pages, with a number of 

 illustrations, contains a mass of entomological lore, chiefly having to

Horsham. (Some notes and records are embodied.) 

 Judging by this report the Society is in a flourishing condition. 

 Its motto, " In Natm-a Deus," will appeal to the genuine lover of 

 Nature. 



6. Ants found in Great Britain. By H. St. J. Dgnisthgrpe, F.Z.S., 



F.E.S. 1908. 

 This is a paper read before the Leicester Literary and Philo- 

 sophical Society, in which the author gives short interesting notes 

 on the appearance, habits, distribution, and so forth, of the British 

 ants, including introduced species. As Mr. Donisthorpe has taken 

 all the British ants, he is able to speak with authority on these 

 interesting insects. The paper will be of the greatest value to 

 students of our Hymenoptera.
