142 THE CANADIAN ENTOMOLOGIST. 



index. This is a great misfortune, as the rising generation of entomolo- 

 gists who accept this book will have nothing by which to connect the new 

 designations with those employed in the older literature. 



Time and space will not permit us to discuss the larger field of the 

 Heterocera. Many, no doubt, will be surprised at the arrangement 

 of families, which places the Notodontidse, Bombycid^e, etc., between the 

 Noctuidie and Geometrid?e. The restoration of the Papilionidas to the 

 head of the Lepidoptera has been fully justified by Prof. Grote. 



The preparation of this list has evidently involved a very large 

 expenditure of time and labour, and we must all acknowledge that the 

 author has placed us under a deep debt of obligation to him. The 

 work, notwithstanding any criticisms that may be passed upon it, 

 is an extremely valuable one, and will be found by its possessors to be 

 most useful, and, indeed, indispensable. Though we may not agree with 

 it on all points, we must admit its excellence and importance, and we beg 

 to congratulate the author on his achievement, and thank him for what he 

 has accomplished. Our hearty thanks are also due to the Smithsonian 

 Institution for its generosity in issuing the work free of charge. 



By a strange oversight the Canadian Entomologist has been 

 omitted from the periodicals in the list of works quoted, though it is 

 referred to on nearly every page of the book. 



Elementary Studies in Insect Life. — By Samuel J. Hunter, Univer- 

 sity of Kansas. Crane & Company, publishers, Topeka, Kansas. 

 I vol., 8vo., pp. 344. (Price, $1.25.) 



We are glad to welcome a book from the West that aims at popular- 

 izing the study of Entomology. Prof. Hunter's object is " to induce the 

 student to become acquainted, through personal observations in the field 

 and laboratory, with some of the important biological problems presented 

 by insects." He carries out his plan in a series of well-illustrated chapters 

 dealing with the lives of some typical insects, their special senses and pro- 

 tective devices, those that live solitary or social lives, their instincts and 

 their relations to plants ; these are followed by short descriptions of injuri- 

 ous and beneficial insects, and of the principal orders, and some remarks 

 ujK)n their geographical distribution and their struggle for life. The re- 

 mainder of the book gives instructions for forming a collection, for breed- 

 ing specimens in order to observe their life-history and for laboratory work 

 for the study of their structure. The volume is profusely illustrated with 

 two plates and over 250 figures, most of which are original and excellent. 

 It will no doubt be found of much service by beginners in the pursuit of 

 Entomology and by teachers who are called upon to give instruction in 

 Nature Study.
