INJURIOUS 

 AND USEFUL INSECTS 



AN INTRODUCTION TO THE STUDY OF 

 ECONOMIC ENTOMOLOGY 



BY 



L. C. MI ALL, F.R.S. 



Formerly Professor of Biology in the University of Leeds 



" Those requiring a rudimentary knowledge in general entomology will 

 find this little book, by Professor Miall, both interesting and instructive as 

 an introductory guide." Field. 



"All teachers of economic zoology must feel grateful to Professor 

 Miall for this excellent little book, from which a student can hardly fail 

 to learn how to observe, think, and act for himself. . . . The style of the 

 book is beautifully clear, and the facts are set forth so as to attract anc 

 fascinate the student. The book cannot fail in the full sense of the wore 

 to educate naturalists." Knowledge. 



" Professor Miall has been happily inspired ; he has given us just the 

 book which was wanted, just the book which we might expect from 

 him. When we have said that the promise of the preface is entirely 

 fulfilled in the book, no more is necessary." Pilot. 



" Beginners who wish to acquire a practical knowledge of our commor 

 insects will find this book most useful. It commences with a short course 

 of practical work on the structure of the cockroach, and then passes on 

 the examination in order of difficulty of the structure and life histo 

 of well-known types of the various orders. Part III. deals with classi 

 fication and Part IV. with methods of exterminating insect pests. We ar 

 glad to see that Professor Miall employs plain English, wherever possib 

 in place of the technical terms which too often repel the elementar 

 student from one of the most fascinating branches of biology." Schot
