members of each of the 24 Classes of insects, which the author- 

 recognises, most of the examples chosen for description and illustration 

 being in some portion or other of their life more or less injurious to 

 man or to his crops. The book being primarily for American students, 

 the types chosen are all from the Western Hemisphere and most of 

 them dominant species of that fauna. This, however, should in no 

 way deter readers on this side of the Atlantic, as the two areas have so 

 much in common that even if the particular species used does not 

 occur in Great Britain, a closely allied species of the same genus does 

 occur, often undistinguishable at the first glance and with quite 

 similar habits and habitats. Opening the book at random one finds, 

 for instance, the carrion beetle a Silpha, the larder beetle Dermestes 

 lardarius, the June bug Phyllopertha, the asparagus beetle Grioceris- 

 a'sparagi, the two-spotted lady-beetle Adalia bipunctatus, the gypsy- 

 moth Porthesia dispar, the bee moth Galleria mellonella, and so on. 

 Thus insensibly, as it were, the British student is led to a knowledge 

 of the main features of the American insect fauna, by a study of 

 species which have been selected particularly to unite the several 

 points of view comprised in the author's object. With the account of 

 the life-history of each selected species are added paragraphs concern- 

 ing the specific controls which most adequately keep a check upon the 

 over increase and development of the creature. The illustrations are 

 quite adequate in execution and in sufficient number, as practically 

 every species selected is figured, often with its various stages and 

 characteristic depredations. 



Not only has the author well carried out his aim for the class room, 

 but he has further succeeded in producing a book which should' be of 

 much practical use to all outside who are interested in economic 

 entomology. The publishers, too, have done their work quite well 

 and we congratulate the author who has made an excellent and 

 successful attempt to follow the footsteps of his able and learned 

 father in entomological study. — Hy.J.T.
