392 SYSTEM OF INSECTS. 
order which will afford an example of every group that 
we have lately named. Mr. MacLeay, from a consi- 
deration of the larvae of that Order, has divided the Co- 
leoptera into five primary groups that may be denomi- 
nated Suborders. Whether these are all natural groups 
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 maxillee 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 Hydrode- 
phagena. ‘These two subsections are each resolvable 
into two Trzbes constituted by Linné’s four genera Czcin- 
dela and Carabus ; Dytiscus and Gyrinus. ‘The first tribe, 
remarkable for the swiftness of their flight, I would name 
Eupterina, or fliers; the second, equally noted for run- 
ning, Eupodina, or runners; the third Hunechina, or 
swimmers; and the fourth Gyronechina, or swimmers in 
acircle. ‘The second of these groups, the Hupodina, are 
resolvable into two other groups or Sudtribes ; one dis- 
tinguished by having the cubit or anterior 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 bril- 
liancy 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
