Decade the Fjlrs^t. 

 As many insects are noticed in the Introduction to Entomology 

 that either properly belong to genera not yet established, or are 

 altogether unknown, or have not before been specifically de- 

 scribed, I shall take the liberty of presenting to the Zoological 

 Club, by decades, or larger portions, as my avocations may per- 

 mit, descriptions of them, beginning with some Coleoptera. The 

 first I shall notice is one of the many additional new genera that 

 may be separated from the great Linnean genus Carabus.

Labrum transversum antice ciliatum. 

 MandibulcE forficatae, edentulae, triquetrae, acutae. 

 Labium* trilobum : lobis lateralibus triangularibus longioribus 

 acutis, intermedio obtuso supra inaequali. 



* The Labium of the Introduction to Entomology, for reasons there assigned, is 

 synonymous with the Mentum of M. Latreille ; and the mentum is the piece on which 

 the latter sits.
