into a consistent treatment a vast amount of general and 
specific material relating to practically every phase of 
applied entomology without following any of the usual 
methods of procedure. The first ten chapters relate to gen- 
eral problems and deal with such diverse topics as “climatic 
resistance” “tropic behavior” and “stomach poisons”. 
These serve to show the present extent of the fields invaded 
by the economic entomologist and the methods which he 
applies in his work. The more specific portion, entitled 
“Area Problems” deals with the problems that confront the 
entomologist in particular parts of the world and includes 
a discussion of the multitude of insects that have forced 
themselves upon the attention of agriculturists, foresters 
and medical men in all countries. A discussion of this sort 
has never before been attempted on so broad a scale. A very 
extensive and well arranged bibliography completes the 
book. 
Professional entomologists will find this book extremely 
valuable and for all others interested in the problems with 
which it deals, it will be a useful compendium.
