nature's control methods. Artificial methods of control are treated in 

 Chapter VI (pp. 38-42), insecticides and fumigation in Chapters VII-IX, 

 (pp. 43-58). Chapter X is on the relationships of insects, while each 

 one of the remaining twenty-four Chapters is devoted to a separate 

 order of insects, that on the Lepidoptera being the longest (70 pages). 

 In the NEWS for July, 1921 (pages 220-1), we took occasion to com- 

 pare briefly a number of recent American text books on economic 

 entomology. Prof. Fernald's new book is, so far as its arrangement of 

 subject matter is concerned, similar to those by Professors Osborn and 

 Lochhead mentioned in the review quoted and probably (making allow- 

 ances for differences in type form) larger than either of them and is 

 more extensively illustrated. It has apparently been brought fully 

 down to date, is not too technical for its purpose and here and there, 

 in appropriate places (e. g., pages 220, 2%) contains interesting dis- 

 cussions of general problems introduced by the matter immediately 

 preceding them. On the other hand the reviewer prefers the more 

 exact characterizations of the minor groups and subdivisions of insects 

 which are to be found in Lochhead's book, for example, and misses 

 references to entomological literature other than those contained in 

 the sources given for many illustrations. (Advertisement) PHILIP

TUDES DE LEPIDOPTEROLOGIE COMPARES. By CHARLES OBERTHUR. 

 Volume XVIII, part 2. Rennes, France, July 1921. Despite of "la 

 folie bolchevique" this great work has been continued and the present 

 volume has more than usual interest for American students as it 

 treats in part of species found in this part of the world. There are 

 descriptions of four new species of Noctuelidae by Charles Oberthiir. 

 The remaining 252 pages are devoted to a monographic revision of the 

 family Cymatophoridae by Professor C. Houlbert. There are 68 excel- 

 lent half-tone figures and cuts in the text and nine plates with many 

 illustrations, some of them being in color H. SKINNER. 



INSECT LIFE. By C. A. EALAND. London. A. & C. Black, Ltd., 1921, 

 pp. xii, 340, 74 full page illustrations, 24 of which are from photo- 

 graphs, and 50 in color. American agents, The Macmillan Co. Even 

 in these days of universally high prices, the twelve dollars charged for 

 this book is an extremely high price to pay for a general work on 

 entomology, and the prospective purchaser is most assuredly entitled 

 to expect in return for this not inconsiderable sum, a thoroughly mod- 

 ern and painstakingly accurate product of entomological research. In 

 these times of financial stringency one would also expect that only 

 books of exceptional merit would be published, but in the opinion of 

 the reviewer. Mr. Ealand's book falls far short of expectation in all 

 of these matters.
