No. 481] NOTES AND LITERATURE

The remainder of the text is largely devoted to biological phases of 

 the subject. Much material which is not accessible in any other text 

 is here brought together and is treated from a broad l>i<)l()^'i( Ml view- 

 point. The subjects of color and coloration; the origin of aduptJitinns 

 and of species, distribution; the relation of insects U> plants and lo 

 other animals; their interrelations and their behavior, are treated in 

 a concise but most readable and interesting manner. 



Though the method of treatment is professedly economic as well as 

 biologic, the practical aspect of the subject receives but scant attention. 

 The relations of insects to plants, and to other animals, are discussed 

 from the view-point of the biologist. Six pages are devoted to an 

 excellent summary of the important subject of the transmission of 

 disease by insects. The sixteen pages on insects in relation to man 

 are largely given over to a statement of the importance of the subject 

 and to an historical sketch of the progress of economic entomology m 

 America. 



The illustrations are excellent and, in many cases, new and prepared 

 by the author. Such as have been copied are very carefully credited. 

 An extensive and carefully arranged bibliography will be vefy helpful 

 to the student. 



Dr. Folsom is to be congratulated on the clear, concise, and interest- 

 ing presentation of his material. The book is one which is bound to 

 prove stimulating, and which every worker in the field of entomology 

 and every teacher of zoology will want in his o\vn librar>^ Whether 

 it will meet the present day demands for an entomological text-book 

 is a question. ^
