Die wichtigsten Krankheiten und Schaidlinge der Tropischen Kultur- 

 pflanzen, by Dr. Friedkich Zacher, Bandl. 152 pages, 58 text 

 figures. Hamburg. Verlag Fr. W. Thaden. 1914. (Deutsche 

 Tropen-Bibliothek Bd. 10.) 



This little volume treats of the insect and other animal pests as well as the bacterial 

 and fungous diseases which attack tropical plants. The author explains the manner 

 in which diseases are spread by animals, and how they often follow the attacks of 

 insects. 



The greater portion of the book, pages 39 to 152, is devoted to a discussion of the 

 pests of cotton, cocoa, coffee and tea. Each important pest is treated separately 

 and remedial treatment is recommended. Most of the illustrations are made in 

 half-tone from drawings or photographs and are of fair quality. The book is sup- 

 plied with a table of contents, but there is no index.

Insects Injurious to the Household and Annoying to Man, by 

 Glenn W. Herrick, pages i-xviii, 1-470, figs. 152. Macmillan 

 Company. 1914. 



We have in this small volume a concise and authoritative discussion of a large 

 number of insects more or less directly injurious to man or his household possessions. 

 The work is an indirect outcome of the studies of recent years upon insects as disease 

 carriers, though the author does not attempt to exhaust this phase of the problem. 



The first 34 pages are devoted to the house-fly while associated and much less 

 important flies occupy the second chapter of 19 pages. The various mosquitoes, 

 their habits and control are allotted about 50 pages. Short chapters are devoted to 

 the bed-bug, cockroaches and fleas respectively. There is an excellent discussion of 

 the various household ants, which, taken with the matter relating to the Termites 

 (unlike though popularly associated forms) leaves little to be desired. The fabric, 

 cereal and other food pests receive due attention and in concluding chapters there 

 are discussions of human parasites, annoying pests, dry wood borers, poisonous or 

 terrifying insects, presenting much of interest concerning common though not well- 

 known forms. There is an excellent series of illustrations, mostly original, the print- 

 ing is good and the arrangement tasty. 



The general public will find in this volume much practical information presented 

 in a pleasing, untechnical manner, while for the entomologist it means anotlier exceed- 

 ingly useful compilation illuminated by personal experiences in both North and 

 South and supplemented bv excellent bibliographies.
