216 THE CANADIAN ENTOMOLOGIST 



information about insects usually sought by the laity, with whom 

 the author, in connection with his museum work, has long been in 

 close contact. Its usefulness, however, does not stop here, for 

 it will prove invaluable to every young entomologist and service- 

 able even to those of experience. It contains a great deal of in- 

 fcrmation within a small compass, and although necessarily much 

 condensed it is written in simple language as free as possible from 

 technical term.s. 



The first 38 pages contain brief sections of an introductory 

 nature on the sA'stem, growth and structure of insects, longer dis- 

 cussions on collecting and mounting, and on the control of in- 

 j uric us forms, and on insect-like Arthrcpods, particularly spiders. 

 The rest of the bcok treats of the various orders and families, with 

 brief accounts of the commoner or more striking species found in 

 the Northeastern United States. Particular attention is given to 

 such forms are are commonly* observed by the layman, such as the 

 larger, mere conspicuous or more injurious species, but some notice 

 is taken of nearly all the families. Thus we find that a relatively 

 large space is given, and quite properly so, to the butterflies and 

 larger moths and to some of the beetles. The long-horned beetles, 

 however, receive somiewhat more than their share of space, there 

 being a key to the species extending over nearly twenty pages. 

 There are a number of other keys to families and genera and in 

 som.e cases species, and amiong the latter is a useful one to the 

 commoner kinds of Muscid flies, which is followed by brief de- 

 scriptions of the characters and habits of the more important 

 species and of the methods of combatting these dangerous insects. 

 There is also a special section at the end of the book on galls, 

 which is illustrated by a large number of figures. 



The illustrations form a most attractive feature of the book. 

 .Almcst 700 of the entire number are the work of Mrs. E. L. Beuten- 

 muller, who deserves great credit for the faithful manner in which 

 she has performed an enormous task. Some of the coloured 

 plates have suffered in the reproduction but miost of them are 

 satisfactory and the black-and-white figures are almost uniformly 

 excellent. Nearly 600 species are illustrated by one or more figures. 



We heartily recommiCnd this admirable work to every young 

 entomologist and outdoor naturalist.
