The author arranges the genera in three groups: (1) Integri- 

 dorsata (without median slit, band, or row of perforations; (2) 

 Fissidorsata (with fissure) ; and (3) Terelridorsata (with 

 median perforations). c. s.

III. Zoology and Botany. 



1. Sanitary Entomology: The Entomology of Disease, 

 Hygiene, and Sanitation; edited hy William Dwight Pierce. 

 Pp. xxvi, 518, with 28 plates and 88 text-figures. Boston, 1921 

 (Richard G. Badger; price $10). — Just at this time, when there 

 is such fear that the insect-borne diseases now raging in central 

 and eastern Europe may become established in America, this 

 untechnical treatise on the relations of insects arid disease in all 

 parts of the world is most opportune. The book is the outcome 

 of a series of studies prepared by ten specialists for the training 

 of a large number of people for any service which might be 

 required in combating disease-carrying insects during the war. 

 This information is of no less importance, however, in the pre- 

 vention of disease now that peace between so many of the nations 

 has been officially declared, for the louse and other insects con- 

 tinue their daily additions to the millions of deaths for which 

 they have been responsible during the past few years. 



The treatment of the subject is entirely untechnical, so that any 

 intelligent person, without previous knowledge of biology, can 

 learn tlie essential facts about the various ways in which insects 

 transmit the germs . of diseases both to man and domesticated 

 animals and .the practical methods by which these diseases can be 

 prevented or eradicated. The control of all kinds of insect pests 

 in dwellings, farm-yards, packing houses and communities is also 

 given in detail, with recipes for remedial treatment. 



The book includes not only the insects but also the mites and 

 ticks, for the latter rival the insects in the transmission of dis- 

 eases of domesticated animals, as well as by causing injuries by
