notes upon the anatomy and physiology of the alimentary canal ; together 

 with a natural history of the Occident harvesting ants or stone-mound 

 builders of the American plains." It is written in a charming and popular 

 style, and the details of the curious habits of these interesting creatures are 

 given in such a manner as to show that the author has studied them closely 

 and is quite familiar with every aspect of the subject treated of, while the 

 beautiful illustrations are a material aid towards the ready comprehension 

 of the whole matter. This work is well worthy of a place in the library 

 of every student of nature. 



A Manual of Injurious Insects, with Methods of Prevention and 

 Remedy for their Attacks to Food Crops, Forest Trees and Fruit, and 

 with a short Introduction to Entomology. By Eleanor A. Ormerod, 

 F. M. S., London, England, 1881 : 



It is with very great pleasure that we draw attention to Miss Ormerod's 

 excellent work on Injurious Insects — the full title of which we have given 

 above. It is the first effort that has been made in England to bring within 

 the reach and comprehension of ordinary farmers and gardeners a com- 

 plete account of the insect enemies that they have to deal with. The 

 work begins with an introduction to Entomology, in which the reader is 

 furnished with an account of the general life-history of insects during the 

 various stages of their existence, beginning with the egg and going on 

 through the larva and pupa to the imago. This is followed by a sketch 

 of the classification of insects, based upon Prof Westwood's division into 

 thirteen orders, each of which is represented by wood-cuts of common 

 species in order that it may be easily recognised by the reader. The 

 book is divided into three parts, viz.. Food Crops, Forest Trees and Fruit, 

 with the insects that injure them respectively. In each part the various 

 crops, trees, &c., are treated of as regards their insect enemies, in alpha- 

 betical order ; for instance, the " Food Crops " begin with the Asparagus, 

 Bean,, etc., and end with Turnips, thus making it very easy to obtain 

 information about any insect that happens to be prevalent. Every insect 

 treated of in the book is made easily recognisable to the non-scientific 

 reader by means of admirable wood-cuts, partly the work of the talented 

 authoress herself, and partly reproductions of the beautiful illustrations in 

 Curtis' Farm Insects. Each cut shows the insect in the various stages of 

 its existence, while the letter-press gives an account of its life history. As
