Destructive and Useful Insects. By C. L. Metcalf and W. 
P. Flint. McGraw Hill Book Co. New York. $7. 50. 
This book which includes 918 pages, with 561 illustrations, 
is an account of American insects as they affect the welfare of 
man. More than two-thirds of the text deals with the injurious 
and destructive activities of insects that affect agriculture, to- 
gether with a consideration of general and special methods of 
combating them. This is the most valuable part of the book as 
it includes very full accounts of practically all the pests of im- 
portance which affect vegetable crops and fruits. With this is 
a chapter on household insects, one on insects that attack and 
annoy man and another on insects injurious to domestic animals. 
A chapter on the value of insects to man contains much interest- 
ing material which seldom receives space in entomological text- 
books. There is also a brief treatment of the morphology and 
classification of insects. The illustrations are well selected, but 
are nearly all from other publications. 
The authors are certainty to be congratulated in having 
gathered together a large mass of material into an extremely 
useful book, to which economic entomologist and others of their 
less practically inclined brethren will have frequent occasion to 
refer.

Elementary Lessons on Insects. By James G. Needham. 
C. C. Thomas, Springfield 111. and Baltimore Md. $2.00. 
This small volume of somewhat over 200 pages gives an ac- 
count of the structure and development of insects together with 
a consideration of some of their more important economic rela- 
tions. It is suitable for secondary schools, or summer classes as 
a text-book and should be valuable as a vade mecum for teachers 
who require a certain amount of entomological knowledge for 
the teaching of “nature study.” 
Ten of the more important orders of insects are considered 
with general reference to their structure, development and habits.
