106 Bulletin of the Brooklyn Entomological Society Vol. XVI 



1919" (pp. 367 to 444) is a contribution of great value in itself 

 and would alone make this book an indispensable guide to the 

 American coleopterist. The manner in which it is presented adds 

 greatly to its usefulness. The writings of each author are ar- 

 ranged chronologically ; the references to periodicals have not 

 been abbreviated to the point of unintelligibility, while the number 

 of pages covered by the article is given in each case, thus per- 

 mitting an estimate of its probable importance. The title of each 

 paper, though shortened, is of further help in this connection and 

 will also aid considerably in locating the article in the library. 

 About 4,cxDO titles of contributions by about 700 authors are re- 

 corded in this part of the work, which may safely be adjudged 

 one of the most complete of its kind. Though it was the author's 

 intention to list only the taxonomic papers, even a cursory exam- 

 ination shows that the scope is much wider, so that this bibli- 

 ography will undoubtedly render great service to the student of 

 ethology and to the economic entomologist also. It is apparent 

 that practically all the writings of some of the leading North 

 American specialists on the subject have been listed, and, if it 

 were only from the point of view of numbers, the contributions 

 of Mr. E, A. Schwarz, the Nestor of North American coleop- 

 terists, stand prominent. 



An index (pp. 445-470) to the names of genera, subgenera and 

 higher groups concludes the volume. 



Mr. Leng is to be congratulated for having so successfully 

 completed his tedious task, embodied in a volume that not only 

 will be a useful reference work for many years to come, but also 

 will stand out as a mile-stone in the progress of entomology. 

 The editor, Mr. John D. Sherman, Jr., deserves full praise for 

 the splendid manner in which the volume has been presented. 

 Both the quality of the paper and the typographical execution are 

 of the best. While the price of the volume ($10) may to some 

 seem rather high for the modest purse of the average entomolo- 

 gist, it is, as a matter of fact, quite moderate considering present 

 printing conditions, which would rapidly make entomological pub- 

 lications a financial impossibility were it not for the voluntary 

 contributions of a few enthusiastic devotees.
