rather than to create. So I will close this brief history with 

 a notice of authors who are very serviceable to such as may 

 desire to glean farther of the treasures of systematic ento- 

 mology ; only remarking that at the end of the next chapter 

 I shall refer to those who have been particularly serviceable 

 in developing the anatomy and physiology of insects, especially 

 of bees. 



VALUABLE BOOKS FOR THE STUDENT OJJ' ENTOMOLOGY. 



For mere classification, no work is equal to Westwood on 

 Insects — two volumes. In this the descriptions and illustra- 

 tions are very full and perfect, making it easy to study the 

 families, and even genera, of all the sub-orders. This work 

 and the following are out of print, but can be got with little 

 trouble at second-hand book-stores. 



Kirby and Spence — Introduction to Entomology — is a very 

 complete work. It treats of the classification, structure, 

 habits, general economy of insects, and gives a history of the 

 subject. It is an invaluable work, and a great acquisition to 

 any library. 



Dr. Packard's Guide to the Study of insects is a valuable 

 work, and being American, is specially to be recommended. 



The Eeports of Dr. T. Harris, Dr. A. Fitch, and of Prof. 

 C. V. Kiley, will also be found of great value and interest.
