Manual for the Study of Insects. — By John Henry Corn- 

 stock, Professor of Entomology in Cornell University and in 

 Leland Stanford Junior Universit3^ 



This work has been prepared to meet the need for an elemen- 

 tary, systematic text-book for the use of students in high 

 schools and colleges and of teachers in primary and secondary 

 schools. Its most distinctive feature is a series of analytical 

 keys by means of which the family to which any North Amer- 

 ican insect belongs can be determined. Under the head of each 

 family the characteristics of the fomily, both as regards struc- 

 ture and habits are given, and the more common sjoecies 

 described. It is thus possible for the student to classify any 

 insect to its family and to learn the habits of the insects of that 

 family, and, in case of the more common species, to learn the 

 name of the insect. 



The book is profusely illustrated with figures prepared es- 

 pecially for it. A large proportion of these were engraved from 

 nature by Mrs. Com stock. 



Although the book is a large one and gotten up in an expen- 

 sive style it is sold for a nominal price, the preparation of it 

 having been a work of love rather than a financial venture. It 

 is hoped that its low price, $3.75 net or 84.09 postpaid, will 

 bring it within the reach of all who desire to learn something of 

 insects and their ways.
