50 Entomological Books. 



synopsis of the Hymenoptera of North America, together 

 with a list of the described species. This is one of the 

 many valuable publications of the American Entomolog- 

 ical Society. 



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 pleasures of systematic entomology ; only 

 remarking that at the end of the next chapter I shall refer 

 to those who have been particularly serviceable in devel- 

 oping the anatomy and physiology of insects, especially of 

 bees. 



VALUABLE BOOKS FOR THE STUDENT OF ENTOMOLOGY. 



For mere classification, no work is equal to Westwood 

 on Insects — two volumes. In this the descriptions and 

 illustrations are very full and perfect, making it easy 

 to study the families, and even genera, of all the 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 com- 

 plete work. It treats of the classification, structure, habits, 

 general economy of insects, and gives a history of the sub- 

 ject. 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. " Injurious Insects " is the title of two 

 valuable books, one by Dr. T. Harris, and the other by 

 Mary Treat. The Reports of Dr. T. Harris, Dr. A. 

 Fitch, and Dr. C. V. Riley, the Illinois Entomological 

 Reports, and the Entomological Reports of the Depart- 

 ments of the Interior, and of Agriculture, will also be 

 found of great value and interest. Cresson's Synopsis, 

 already referred to, will be indispensable to every student 

 of bees or other Hymenopterous insects.
