BOOK NOTICES. 



An Outline of the Theory of Organic Evolution, with a description of 

 some of the phenomena which it explains. By Maynard M. 

 Metcalf, Ph.D., Professor of Biology in the Woman's College of 

 Baltimore. New York, The Macmillan Company, 1904. 

 Professor Metcalf presents his subject in a compact and readable 

 style with numerous illustrations. Several color plates of moths, butter- 

 flies and spiders give a good idea of the " mimicry " which is so well 

 shown by these insects. The book has resulted from a course of lec- 

 tures and is therefore well adapted for students. 



American Insects. By VernonL. Kellogg, Professor of Entomology 

 and Lecturer on Bionomics in Leland Stanford Jr. University, with 

 many original illustrations by Mary Wellman. New York, Henry 

 Holt and Company, 1905. 



This bulky volume of 674 pages gives a general outline of all 

 American insects and deals more largely with anatomy than is usually 

 the case with books of this class. The classification is after Comstock 

 and the synoptic tables are largely remodeled after his. The work is 

 adapted only for beginners or general students (if there are any such) 

 and does not lead to specific determinations. It is almost up to date, 

 including a chapter on mosquitoes and disease. It ends with an ac- 

 count of collecting and rearing insects, which one would fancy must 

 be a laborious undertaking from the amount of apparatus illustrated. 

 Jelly tumblers have always served for us. 



Wilhelm Junk Entomologen-Adressbuch. Preis Mark 5. W. Junk, 

 Yerlag fur Entomologie. Berlin, 1905, NW., Rathenower 

 Strasse 22. 



Another entomological address book is before us, well printed and 

 in convenient, compact form. We notice some names not in other 

 similar works which is commendable. There are also some curious 

 errors. For instance, Mr. Geo. Franck, whose name will be found in 

 our list of members published with the June issue of this Journal, 

 appears under the pseudonym of " Iranck," both in text and index. 

 It would be an advantage if publishers of address books could combine 

 on one really good book instead of scattering their efforts as at present.
