SYSTEM OF INSECTS. 401 



has not yet been made sufficiently evident. It answers 

 my present purpose, however, to assume it as proved. I 

 select therefore his Chilopodimorpha for my suborder, 

 altering the name as above proposed to Chilopodimor- 

 phita : for my Section I take the Predaceous beetles, or 

 Adephaga of M. Clairville, distinguished by having the 

 upper lobe of their maxillae biarticulate and palpiform; 

 these I would denominate Adephagana, or devourers. 

 They consist of two groups forming two subsections, the 

 one terrestrial and the other aquatic ; which I would 

 name, following Mr. MacLeay, Geodephagena and Hy- 

 drodephagena. These two subsections are each resolv- 

 able into two Tribes constituted by Linne's four genera 

 Cicindela and Carabus ; Dytiscus and Gyrinus. The 

 first tribe, remarkable for the swiftness of their^zg/z/, I 

 would name Eupterma, or fliers ; the second, equally 

 noted for running, Eutrech'ma, or runners ; the third 

 Eunech'ma, or swimmers ; and the fourth Gyronechma, 

 or swimmers in a circle. The second of these groups, 

 the Eutrechma, are resolvable into two other groups or 

 Subtribes ; one distinguished by having the cubit or an- 

 terior tibia notched, (which, from their being in general 

 not very brilliant in colour, I would call Amazirona, or 

 obscure); the other having the cubit without a notch, 

 (which, from the brilliancy of many of them, I would 

 name Lamprona, or splendid). These subtribes are 

 both further resolvable into two or more races (Stirpes). 

 I select that to which the crepitant Eutrech'ma belong, 

 containing those which from their usually truncated 

 elytra MM. Latreille and Dejean have named Trunca- 

 tipennes a : these, to shorten the name, I call Truncipen-
