more than one representative of the genus. The fifteen plates with which 

 the volume is illustrated are very beautiful, and are admirably drawn by 

 the author himself. Each species is represented life-size, and is shown as 

 a caterpillar on its food-plant, chrysalis, and imago. There are also 

 eighteen wood-cuts, for the most part illustrating details of structure. It 

 is to be hoped that the author will continue his good work until he has 

 completed the British Lepidoptera, or at any rate the more conspicuous 

 and familiar families. 



Life Histories of American Insects. — By Clarence M. Weed : i vol.,- 

 pp. 272. ($1.50.) New York : The Macmillan Company. 



The publication of a popular book on insects is so rare an event on 

 this side of the Atlantic that we heartily welcome an addition to the 

 number, especially when it is so excellent and satisfactory as the volume 

 before us. Dr. Weed has selected some five and twenty more or less 

 familiar insects, and in a pleasant manner has given some account of their 

 life histories. The chapters are quite independent of each other and 

 arranged in no particular order ; the book may therefore be opened at 

 random, and the sketch that may be hit upon read without any detriment 

 to the continuity of the work. Some of them which deal with such 

 creatures as the leaf-miners are naturally very brief, since so little is known 

 about these tiny foes to vegetation, but of other species which have been 

 subjects of particular study on the part of the author we find long and full 

 descriptions. Among the latter may be mentioned the interesting account 

 of the hibernation of aphides, the chapters on " harvest spiders," the 

 " army-worm," etc. Any one, young or old, who has any desire to read 

 about the wonderful creatures that inhabit the world, and to know some- 

 thing about their modes of life, cannot fail to be pleased with this book, 

 and to be led on, we should hope, to make his own observations of their 

 curious habits and strange doings. The volume is handsomely illustrated 

 with 21 full-page plates and nearly 100 figures in the text.

In the Annual Report of the Entomological Society of Ontario for 

 1896 much attention was paid to the subject of teaching natural history, 

 and especially entomology, in schools, and the desire Avas expressed that
