396 THE CANADIAN ENTOMOLOGIST 



associating with him Mr. Leng, who had for some time been work- 

 ing on the \Vec\ils of the Atlantic Coast, he has been able to extend 

 the scope of the volume so as to include the United States and 

 Canada, east of the Mississippi River, thus going far beyond the 

 bounds of the State of Indiana, to whose Coleopterous fauna 

 the previous book was confined. The \olume contains 682 pages 

 and is illustrated with 155 figures. 



In their introduction the authors state that their "primary 

 object has been to furnish to students and tyros in Entomology 

 a simple manual which would enable them in the most direct 

 way possible to arrange, classify and determine the scientific 

 names of the weevils in their collections." In accordance with 

 this design the work begins with an explanation of the external 

 anatomy of these beetles, with clear figures of the various structures. 

 After a careful study of these details the reader will be able to go 

 on and make good use of the book. F'our families are recognized, 

 namely, the Brenthida\ Anthril)idie, Curculionidre and Scolytidae; 

 to the third of these over five hundred pages are devoted, and de- 

 scriptions are gi\en of 856 species distributed among thirteen 

 sub-families. 



According to the plan of the work, a general description (^f e^ich 

 family is given, followed by keys to the genera, which in turn are 

 described and usually illustrated with a characteristic figure, 

 assisting materially in their recognition. After the genus a key 

 is given to the species, followed by descriptions, with an account 

 of their geographical range, habits, dates of capture and other 

 particulars. By a careful use of the keys, a species may be run 

 down and a specimen identified with comparati\ely little difficulty. 



At the end of the volume there is a Bibliography of the works 

 that have been referred to, and Indexes to the Plants affected by 

 weevils, the Families, Sub-families, Tribes and Genera. 



We may justly congratulate the authors on the completion 

 of such an excellent w^ork, which must have involved a very large 

 amount of most painstaking labour. The book will be eagerly 

 welcomed by all entomologists who are interested in this division 

 of the Coleoptera, and should render more popular the collection 

 and study of the Rhyncophora now that facilities for doing so 

 are admirably supplied. C. J. S. B.
