manual covers about 260 pages, and is illustrated by 95 woodcuts 

 showing a number of injurious species and their work. The arrange- 

 ment is not according to crops, as is usual in works of this character, 

 but according to the systematic classification of insects. The little 

 book is of a most convenient size and costs only two lire. 



Insects and Insecticides.*— Dr. Weed's new book follows in about the 

 same line with that of Franceschiui. It is a handy volume of nearly 

 300 pages, Illustrated with 143 cuts and 7 full-page plates. The ar- 

 rangement is a convenient one, comprehending insects affecting the 

 larger fruits, insects affecting small fruits, insects affecting shade trees, 

 ornamental plants, and flowers, insects affecting vegetables, insects 

 affecting cereal and forage crops, and insect pests of domestic animals 

 and of the household. The introduction includes sections upon the me- 

 tamorphoses of insects, their classification relative to the application of 

 insecticides, natural enemies, the principal insecticides, methods of 

 application, and collecting and preserving specimens. The treatment 

 of the different species is similar in plan to that used by Saunders and 

 Matthew Cooke in their manuals, and consists of a plain statement of the 

 life-history, with figures of the different stages and a concluding para- 

 graph upon remedies. The style is simple and non-technical and the 

 important facts are condensed in a clear, concise manner. The first 

 three parts of the volume are reprinted from the Report of the Colum- 

 bus (Ohio) Horticultural Society for 1890, the last three only being orig- 

 inal here. Owiug to the condensed method of presentation the author 

 has found it impracticable to give full credit to each observer from 

 whose writings he has drawn, but he has fully accredited the illustra- 

 tions in the preface. The work will prove useful to the fruit-grower, 

 general farmer, and housekeeper, and will unquestionably meet a de- 

 mand among those who have not access to entomological libraries. 



Tertiary Insects of North America.— Vol. XIII of the Reports of the 

 U. S. Geological Survey of the Territories is devoted to Mr. S, H. 

 Scudder's Monograph of the Tertiary Insects of this country. Mr. 

 Scudder has been at work upon this volume for twelve years or more, 

 and he gives careful descriptions of 612 species, nearly all of which are 

 figured upon beautiful lithographic plates. As the author states 

 in his letter of transmittal, the publication of this volume will give the 

 first opportunity for good comparisons between the long-known Ter- 

 tiary insects of Europe and those of any other country. The material 

 gathered shows that the fauna is at least as rich as that of Europe iu
