to methods of control. Some 55 species are treated, the larva or 
wrigglers of 43 are described, and accounts of their habits and life 
history are given. There are tables for the separation of adults and 
larvee, and the value of the work is greatly enhanced by over 100 origi- 
nalline-drawings and 57 excellent process plates reproduced from 
the author's photomicrographs. The keys and illustrations should 
enable physicians, and in fact almost any person having a fair micro- 
Scope at his disposal, to identify most of the common forms in either 
the adult or the larval stage. This bulletin should also appeal to 
teachers interested in nature study, since no group of insects lends

of living and mounted specimens illustrate the paper.

by C. S. Brimley (Journ. Elisha Mitchell Sci. Soc., 1905) records 66 
species at present known from the State. Short notes on the distri- 
bution and analytical keys for determination of the species, make it 
of general value to others than specialists.

La sociologie génétique ! — genetic sociology — occupies itself, 
according to the definition of the author (p. 3) with *the origin of 
human society and all the phenomena by which it is influenced ; the 
term being equivalent with social embryogeny.”  - : 
The writer endeavors in one small volume to give an outline of the 
sources and development of the essential constituents of human 
organization, and he is not entirely successful. He has produced a 
work of generalities and philosophy, on facts that are not always 
ample enough, or fully reliable. 
The material utilized consists of (1) studies of animal societies 
and animal life; (2) studies of savage. peoples; (3) results of
