A decade of work has come to partial fruition in two volumes of a magnificent 

 monograph — a work highly creditable alike to the authors, the numerous collaborators 

 and the institution standing sponsor for the undertaking. 



The first volume, introductory and practical in nature, presents in a condensed 

 form a wonderful amount of information and is a logical introduction to the systematic 

 discussion in the third and fourth volumes. The magnitude of the task has prevented 

 the authors and their collaborators from investigating all phases of the subject, and 

 we find throughout this first volume, excerpts from the writings of various investiga- 

 tors. The authors have given particular attention to the historical development of 

 our knowledge of mosquitos along various lines and great care has been exercised in 

 giving credit to different parties. 



The introduction outhnes the causes resulting in the recently developed great in- 

 terest in mosquitos, records briefly the typical regions in which the Culicid fauna was 

 studied and acknowledges the services of many collaborators. The next few pages 

 give a vivid idea of the pestiferous potentialities of mosquitos, and this is followed 

 by a summary of earlier accounts relating to Culicid biology. The structure of the 

 adult is discussed in .59 pages, that of the internal anatomy being from Stephens and 

 Christophers. The consideration of the larva is an excellent morphologic and taxo- 

 nomic exposition and gives, within a small compass, a good idea of the development of 

 these forms. • The behavior of the adults has been carefully studied by the authors, 

 there being detailed observations on the food habits, song, hearing, longevity, hiber- 

 nation, mating, the superabundance of mosquitos, especially in the northwest and 

 Alaska, and the deposition of eggs. 



The importance of a knowledge of mosquito larvis is fully recognized and we find a 

 succinct though comprehensive account of their habits, food and natural enemies, 

 the latter topic occupying 21 pages of text. 



The place of the mosquito as a disease carrier is fully discussed, this topic including 

 detailed accounts of the important disease carriers, namely, the malaria and yellow 

 fever mosquitos, and occupying over 1.30 pages. There is most suggestive data on the 

 losses caused by malaria and an exceedingly instructive discus.sion of the decrease and 

 increase of this disease following settlement of the country and the attention or lack of
