162 THE CANADIAN ENTOMOLOGIST. 



Lyons, France, who, with Mr. Fall, of Pasadena, California, is one of the 

 few living entomologists who is thoroughly familiar with this family of 

 Coleoptera. He divides it into five tribes and 22 genera, and recognizes 

 about 440 species ; the plate, which is clearly executed, gives the charac- 

 ters of all the genera. 



Part 4 contains only three pages and a plate, and gives a description 

 and illustrations, by Mr. P. Wytsman, of the genus Leptocircus, which 

 forms the subfamily Leptocircina 3 of the Papilionidae (Lepidoptera, 

 Rhopalocera). The plate gives excellent figures of each of the six species 

 of these beautiful Oriental butterflies, with the venation and other details. 



These two parts are in French, but we were in error in stating in our 

 notice of Part 1 that French was to be the language employed in the 

 work. Each contributor will write in English, French or German, which- 

 ever may be most convenient to him. 



Parts 5 and 6, which are about to be issued, will be devoted to the 

 Lepidoptera. In the former, Dr. A. Pagenstecher takes up the Libytheidaa 

 and divides the family into three genera, Libythea, Hypatus and Dichora- 

 He recognizes only ten species, all the others being considered to be 

 varieties. The text (four pages) will be illustrated with a beautiful 

 coloured plate. 



Part 6 will contain a very extended study of the Ornithopterinaj, the 

 subfamily of the Papilionidte which includes some of the most magnificent 

 butterflies in the world, by Mr. Robert Rippon, of London, England, the 

 author of the great work, " Icones Ornithopterorum." He has paid great 

 attention to these "Butterflies of Paradise," as he calls them, and as the 

 result of his studies divides the group into six genera: 1, Drurya (2 

 species) ; 2, Schoenbergia (4 sp. and 3 varieties); 3, Ornithoptera (11 sp. 

 and 1 1 vars.); 4, ^-Etheoptera (3 sp.); $,Trogo?ioptera (2 sp.); 6,Pompeoptera 

 (24 sp. and 16 vars.). The part will be illustrated with two beautifully- 

 coloured plates. 



The plan adopted for this great work is certainly excellent, as each 

 family, or subfamily, will be treated by the best specialist known, in what- 

 ever part of the world he may be. It is an immense undertaking, and the 

 enterprising publisher should receive the support of all the important 

 libraries in every country. 



Mailed June 9th, 1902.
