THE CANADIAN ENTOMOLOGIST. 21 



Very carefully and completely done. The life-history of each insect de- 

 scribed is as far as possible fully given j the best published descriptions 

 of each stage are quoted and references given wherever the author has 

 not made personal observations himself, or whenever he thinks that some- 

 one else's record is better or fuller than his own. Thus the work is made 

 complete to date, and succeeding observers will know what investigations 

 have been made, and what remains to be done in this vast field of ento- 

 mological research. The coloured plates are beautifully and accurately 

 done, and the wood cuts and other illustrations give careful details or full 

 representations of a large number of the insects referred to in the text. 

 Such a publication ought to encourage our own Government to follow the 

 noble example set them in this respect at Washington. 



A Series oF Thirty Coloured Diagrams of Insects Injurious to 

 Farm Crops. Drawn from nature by Miss Georgiana E. Ormerodi 

 W. & A. K. Johnston, London, England, i8gr. 

 These diagrams are beautifully and accurately executed, and will be 

 found most useful by any one who is called upon to lecture to classes in 

 entomology, or give addresses to farmers' institutes. They are sufficiently 

 large, being thirty inches long and twenty-two wide, to be seen at some 

 distance in a hall or class-room, and will serve to illustrate descriptions of 

 an economic character. Though intended for England, nearly all of them 

 are equally applicable to this country. They are divided into five sets of 

 six each, which deal with the following objects : — (i) Common Insect 

 Attacks : Ox Warble Flv, Horse Bot-fly, Large While Butterfly, Cockchafer, 

 Turnip Flea-beetle. Onion Fly; (2) Insects Affecting Various Kinds of 

 Crops : Surface Caterpillars, Daddy Longlegs, Eel-worms, Plant Bugs, 

 Hessian Fly, Wire-worm; (3) Insects Affecting Particular Crops : Mangold 

 Fly, Hop Aphis, Bean Beetle, Corn Thrips, Gout Fly, Corn Saw-fly ; (4) 

 Insects Affecting Fruit Crops : Winter Moth, American Blight (Aphis), 

 Gooseberry and Currant Saw-fly, Apple Blossom Weevil, Codlin 

 Moth, Magpie Moth ; (5) Insects Affecting Trees : Pine Beetle, 

 Pine Weevil, Pine Saw fly. Goat Moth, Spruce Gall Aphis, Leopard 

 Moth. The diagrams are sold singly at one shilling and six- 

 pence each, or in sets. On each is shewn the natural size of the 

 insect as well as the greatly enlarged picture, a very necessary 

 matter, as otherwise most erroneous impressions are formed by the 

 ignorant of the real dimensions of the creature referred to. There is 

 also printed on each a general description, by Miss Eleanor A. Ormerod, 

 of the life-history of the insect depicted, and of the best remedies to be 

 employed against it.
