244 JOURNAL OF ECONOMIC ENTOMOLOGY [Vol. 14 



The work is an outcome of 15 years of study and teaching by the author. He has 

 in this period developed a most excellent technique and as an outcome of his studies 

 he has been able to present a very satisfactory morphological discussion of the entire 

 family, the sub-families, and tribes and throughout the large and varied series of 

 forms, he has employed a nomenclature leaving little to be desired. The volume 

 is primarily for the use of students and is somewhat technical, nevertheless the general 

 discussions of the distribution, life history and habits of the more important groups 

 will be of interest to many professional entomologists and not a few amateurs. 

 Prof. MacGillivray has produced a work destined to take a worthy place is 

 entomological literature.

Sanitary Entomology, Entomology cf Disease, Hygiene and Sanita- 

 tion, edited by William Dwight Pierce, Boston, Richard G. 

 Badger, The Gorham Press, pages I to XXVI, 1 to 518, 

 88 figs., 1921. 



This is an exceedingly valuable, comprehensive, closel}' indexed resume of our 

 knowledge of the Entomology of Eli^ease, Hygiene and Sanitation, which had its 

 inception in a class formed in May 1918 among the Entomologists of the country 

 for the purpose of studying recent developments al6ng this line. One need only to 

 turn to the chapter on "Flies and Lice in Egypt" to get a suggestion of the progress 

 which has been made in most civilized countries, though present day practice is 

 very far from what is entirely practicable, if human life and energy are worth conserv- 

 ing. 



This book is more than a digest of current information since it embodies and sum- 

 marizes the investigations and experiences of a group of experts, who have been 

 giving special attention to the varied lines falling within the scope of this volume and 

 at the same time have kept well posted in regard to the activities of other workers. 

 The discovery of the part played by mosquitoes in the dissemination of disease 

 stimulated a very considerable degree of activity, this was followed b}^ material 

 additions to our knowledge of the disease carrying potentialities of other species 

 and the climax was capped by the imperative demand for the control of insect 

 carried diseases during the war, — all summarized in this volume. The work 

 emphasizes the possibilities of prophylaxis resulting from a knowledge of disease 

 carrying insects and methods of controlling them. It covers, however, a broader 

 field, since the authors of the various chapters have recognized the possibilities of 

 further discoveries and have not hesitated to present general discussions of groups 

 likely to be important in this connection, the main effort in this latter being to facili- 

 tate ready identifications and to outline the biology. In addition to extended 

 discussions of mosquitoes, house flies and blow flies, fleas and lice, we find a most 

 valuable account ot the relation of insects to the parasitic wornis ot vertebrates, an 

 excellent summary of the types of injury and life history of those flies producing 

 myiasis, somewhat extended accounts of the blood-sucking flies with relation to both 

 life histories and diseases and dissertations upon cockroaches and the diseases 

 which may be disseminated by these pests of the home, a summary of the relation 

 existing between mites and ticks and various diseases, accounts of animal pests and 

 methods of control on both farm and range and a by no means unimportant feature, 

 namely a twenty-four page tabulation of diseases and insect transmission. The 

 exhaustive index and the well selected bibliographies make possible easy reference to 

 original sources of information.
