42~ Valuable Booh. 



of the honey-bee. His is called the Elective System, as he 

 used wings, mouth-parts, transformations, in fact, all the or- 

 gans — the entire structure. He gave us our Family Apidse, 

 our genus Apis, and, as wiU be remembered, he described 

 several of the species of this genus. In our study of this great 

 man's work, we constantly marvel at his extensive researches 

 and remarkable talents. Lamarck, of this time, except that 

 he could see no God in nature, did very admirable work. So, 

 too, did Cuvier, of Napoleon's time, and the learned Dr. 

 Leach, of England. Since then we have had hosts of workers 

 in this field, and many worthy of not only mention but praise ; 

 yet the work has been to rub up and garnish, rather tiban to 

 create. 



I will close this brief history with a notiOe of authors who are 

 very serviceable to such as may desire to glean farther of the 

 treasures of systematic entomology ; 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 physi- 

 ology of insects, especially of bees. 



VALCIABLE BOOKS FOB THE STUDENT OP 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 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 — In- 

 troduction to Entoniology — is a very complete work. It treats 

 of the classification, structure, habits, general economy of in- 

 sects, 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.' "Injurious In- 

 sects" is the title of two valuable books, one by Dr. T. Harris, 

 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 Departments 

 of the Interior, and of Agriculture, will also be found of great 

 value and interest.
