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 potentiality, and 
its normal numbers so re-established.—S. J. Benn, Hon. Sec.

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

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

5. Christ's Hospital Natural History Society Report for 1908. 
Horsham. (Some notes and records are embodied.) 
Judging by this report the Society is in a flourishing condition. 
Its motto, ‘In Natura Deus,” will appeal to the genuine lover of 
Nature. 
6. Ants found in Great Britain. By H. St. J. Dontstuorer, 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.
