specific name instead of the older haldemanii. The author accords the 

 same treatment to the three "species" usually known as stevensonii, 

 minutus and scudderi. 



The treatment of Anabrus is particularly interesting on account of 

 the great difficulty workers have found in endeavoring to determine in- 

 dividuals of this genus. Uhler's purpurascens is considered a synonym of 

 the typical Anabrus simplex, while coloradus Thomas is made one of 

 three varieties of the type species. Cacoptcris Scudder is shown to be a 

 synonym of Idiostafus Pictet, while Stciroxys bilincata Thomas is trans- 

 ferred to the same genus, in addition to which Pictet's Idiostafus calif ami- 

 cus is made a synonym of hcrmanii Thomas. Platyclcis flctchcri new 

 species, from Calgary. Asfiniboia is remarkable as being the first New 

 World representative of a hitherto Palaearctic genus. 



The author of this revision of the American Decticina? has given us a 

 valuable and distinctly useful work and one for which the systematic 

 Orthopterist is deeply indebted to him. — J. A. G. R. 



Darwinism To-Day. A Discussion of Present-Day Scientific 

 Criticism of the Darwinian Selection Theories, together 

 with a Brief Account of the Principal other Proposed 

 Auxiliary and Alternative Theories of Species Forming. 

 — By Vernon L. Kellogg, Professor in Leland Stanford, Jr., Uni- 

 versity. New York : Henry Holt & Company. 

 In this work Professor Kellogg has given a very able and painstaking 

 exposition of Darwinism past and present. The voluminous literature 

 of the subject has been very thoroughly searched and the book is an 

 excellent one for those that have neither the time or inclination to read 

 through such a mass of detail for themselves. Valuable appendices 

 giving the bibliography are at the end of chapters, and in many cases 

 extracts from original sources. The work is primarily divided into two 

 parts, Darwinism attacked and Darwinism defended. 



Insects Injurious to Vegetables — By F. H. Chittenden, Sc.D., 



United States Department of Agriculture. Illustrated. Orange 



Judd Company, New York. 



This publication will be useful for those who do not have access to the 



literature of the subject and also for those who have and lack the time 



necessary to find it. The author says there are 12,645 titles in American 



economic entomology and 72,000 references to noxious insects. Some 



of the illustrations are crude but are doubtless useful enough for the 



purpose intended.
