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 10 Chilopodimor- 
phita : for my Section I take the Predaceous beetles, or 
Adephaga of M. Clairville, distinguished by having the 
upper lobe of their maxillae Particulate 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 jiight, I 
would name Eupter'ma, or fliers ; the second, equally 
noted for running, Eutrechina, or runners ; the third 
Eunech'ma, or swimmers ; and the fourth Gyronech'ma, 
or swimmers in a circle. The second of these groups, 
the Eutrechina, 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 Amaurona, 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- 
tipcnnes a : these, to shorten the name, I call Truncipen-
