INSECTA. 129 



bilobed tooth on the inner edge of the mandibles (wanting in Calosoma), the 

 decidedly rounded elytra, and the constant want of wings. 



Chaudoir (Bull. Mosc. p. 671) has characterized a great number of new 

 species of various genera, and from the most various parts of the earth, which 

 I have not yet been able to examine closely, since I have only lately received 

 the Part of the work containing them. It appears to me that little is gained 

 by the describing of new species in a journal of limited circulation, and 

 it would perhaps be better that the author, when furnishing additions to the 

 work of Dejean, should allow them to appear in a separate form. When mate- 

 rials are so scattered in all directions they become rather a hiuderance than an 

 assistance in the study of the subject. Entomology in particular, is at pre- 

 sent in that condition, that the description of a new species, without farther 

 object (in itself a witless labour), is of little advantage. In noticing the 

 contents of the present memoir, I can only give the names of the species
