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 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 Reports of Dr. T. Harris, Dr. A. Fitch, and of Prof. C. V. Riley, will also be found of great value and interest.
