may be so general as to make eradication or extermination impractical. 

 This is a problem which has been thrust upon American entomologists 

 by conditions over which they have no control. It must be solved 

 within a few months. The value of the crop threatened is so great 

 and the interests affected so vital to our national welfare, that we feel 

 that nothing short of a most energetic effort to meet the situation and 

 avert, if physically possible, the probability of subsequent enormous 

 annual losses can be justified in the future. 



Review 



Key to American Insect Galls, by Ephraim Porter Felt, D. Sc. 

 Bulletin 200 New York Museum, 310 pages, 16 plates, 250 figures, 

 Albany, N. Y., 1918. 



Though several bulletins and many scattered papers have been published on 

 American insect galls, none have the object or scope of Dr. Felt's work which brings 

 together in one volume a tremendous amount of information in a form most conven- 

 ient for the busy worker to use in identifying galls. In plan, the hosts are arranged 

 according to the botanical relationship of the famihes, and under each family or genus 

 is a workable key or table for separating the galls occurring on the plants of that divi- 

 sion. A large proportion of the galls are illustrated by excellent line drawings or by 

 photographs reproduced in half-tone on the plates. The descriptions, though brief, 

 are sufficient, together with the illustrations for purposes of identification. The in- 

 sects forming galls on each family or group of plants are given in tabular form near 

 the end of the book. An excellent index combining both plant and insect names ren- 

 ders the volume convenient for ready reference. Though Dr. Felt has for many 

 years been studying dipterous galls and has described many new species and pub- 

 lished a number of papers, probably none of his work will be appreciated by entomol- 

 ogists and lajTnen as much as this successful attempt to bring together in one volume, 

 all American gall insects and their hosts, with means of ready identification. (Adu't.)
