BOOK NOTICES. 



Catalogue of British Coleoptera, by Rev. W. W. Fowler, M..A., and 

 Rev. A. Matthews, M. A., London ; West, Newman & Co. 



This Catalogue differs in some respects from all preceding Hsts of 

 British Coleoptera. It is, namely, a partial adaptation of the American 

 views by completely separating the Rhynchophora and Heteromera from 

 the remaining series of the order, and the placing of them after the other 

 series. The changes suggested in the relations of the families of normal 

 Coleoptera, in the system of Drs. Horn and LeConte, are not yet in full 

 favor with the conservative students of Great Britain, but may in future 

 win approval as they become better known. 



The American system, as it may be briefly termed, is fully set forth in 

 the revised " Classification of the Coleoptera of North America," just pub- 

 lished by the Smithsonian Institution. A notice of this work appears 

 below. 



The innovations of the system consist in a re-arrangement of the bulk 

 of the families into four sets : Adephaga, with the most perfected exo- 

 skeleton and powers of locomotion ; Lamellicornia, with the greatest 

 visceral and nervous concentration, and highest development of sense 

 organs ; pseudo-tetramera ; the remainder constitutes a vast complex of 

 Clavicorn and Serricorn families, which may be divided into several ill- 

 defined sub-series.
