also throughout the country. The investigations of special prob- 

 lems by corps of well trained men means the making of entomological 

 history which will have a profound influence upon our future welfare. 

 The relative importance of different phases of this work can not be 

 accurately estimated at the present time. It will be interesting, a 

 generation or so later, to make a critical comparison between the work 

 of our pioneers and those who have had the advantage of the best 

 training a university or special school can bestow.

The Coleoptera or Beetles of Indiana, by W. S. Blatchley, 

 Ind. Dep't of Geol. and Nat. Resources, Bui. 1, p. 1-1386, 590 figures. 

 1910. 



The beetle book has appeared and marks a most important step in further popu- 

 larizing our knowledge of this extensive order. The author follows the classifica- 

 tion of LeConte and Horn and with the cooperation of specialists in many groups 

 has produced a most creditable publication and incidentally laid all entomologists 

 under obligation. The scope of the work, describing as it does, over 2,500 species, 

 compels brevity. Only 24 pages are devoted to introductory matter and that is 

 mostly morphological. The remaining pages consist of a descriptive catalogue 

 exclusive of the Rhynchophora, of all species known to occur in Indiana. Tables 

 are given for the separation of families, tribes, genera and species. The descrip- 

 tions, though brief, are sufficient for the recognition of most species. Citations of 

 the more valuable papers for both groups and genera and a glossary add much ta 

 the value of this work. The large number of illustrations taken from various sources 

 add greatly to the value of the work, though its appearance is somewhat marred by 

 their miscellaneous character. 



This work is indispensable to working entomologists, since it is the first attempt 

 known to us to produce a systematic account of the beetles occurring in any repre- 

 sentative life zone of America. It will be especially valuable to those in the Central 

 States and of great service to others in approximately the same faunal area. We 

 regret to note that it has been possible to issue only 1,000 copies of this bulletin. 

 The author is to be congratulated upon having completed such an extensive work 

 and it is to be hoped that he will soon be able to publish a similar account of the 

 Rhynchophora. 



Insects and Diseases, by Rennie W. Doane, Henry Holt & Co.,. 

 p. 1-227, figures 112. 1910. 



This timely, popular work brings together the most important facts, largely from 

 sources inaccessible to the general reader and even to many physicians and ento- 

 mologists, in regard to the development, habits, structure, life histories and methods 

 of controlUng the insects discussed. This little volume illustrates anew the economic 

 importance of the Diptera, since about one half of the text is devoted to discussions 

 of various flies and methods of controlling them. The house or typhoid fly and vari- 

 ous mosquitoes, especially the forms conveying malaria and yellow fever, are treated 

 in considerable detail. The chapter on ticks and mites and their part in the dis- 

 semination of disease is exceptionally interesting. The chapter devoted to fleas
