BOOK NOTICE 
Classification of Insects. By C. T. Brues and A. L. Melander. 
672 pp., 1125 figs. Published by the Museum of Comparative Zoology, 
Cambridge, Mass. $5.50 (paper), $6.50 (cloth). 
This book consists of keys to the known families of in- 
sects and other terrestrial Arthropods, as well as some 
keys to subfamilies and immature forms. The large and 
representative genera of each family are listed. The text 
is divided into two parts, the first containing keys to the 
classes of Arthropods, orders and families of insects; the 
second including keys to the order and families of other 
terrestrial Arthropods. Technical terms are reduced to 
a minimum, but for the convenience of students a glossary 
of 330 terms and expressions has been added. The useful- 
ness of this work for those who are just entering the field 
of entomology is increased by the inclusion of all synonyms 
of names applied to families and higher groups, and of 
indications of the pronunciation of the names and techni- 
cal terms. Each key is followed by a bibliography of the 
important papers covering the subject of the key. In the 
writer’s opinion these bibliographies, which include about 
2400 references, will undoubtedly be one of the most useful 
features of the book. The complete index, containing over 
10,000 entries, makes this publication invaluable as a ref- 
erence work, as well as a laboratory manual. The authors 
are to be congratulated for the completion of a tedius un- 
dertaking resulting in a publication unique in entomologi- 
cal literature. F. M. C.
