BOOK REVIEW. 



Key to the Families of North American Insects. — An Intro- 

 duction to the Classification of Insects. By Charles T. Brues, 

 Assistant Professor of Economic Entomology, Harvard Uni- 

 versity, and A. L. Melander, Professor of Entomology, State 

 College of Washington, Boston, Mass., and Pullman, Wash. 

 Published by the Authors. 1915. 137 pp.. 18 plates. 

 This little book brings together a complete analytical key to 

 the orders and families of North American insects compiled from

 classification of insects which have been brought about in recent 

 years as a result of the labours of an ever-increasing armv of 

 workers in this field. 



The book "has been prepared to meet the requirements not 

 alone of college courses in systematic entomology, but also of
