Following the suggestions of the later authors, Leconte divided the 
whole family into three sub-families, formed thus : — 
Middle coxse distant ; 
Epimera of the mesonotum reaching the coxse ... 1. Cakabid.®. 
Epimera of the mesonotum not reaching the ooxse ... 3. Harpalid/e. 
Middle coxse contiguous ... ... ... 2. OziENiD.®. 
In the Carabidre, he placed the tribes Omophronini, Hiletmi, Carabini, 
and Scaritini. To the second sub-family he attached the Ozcenini and 
Pseudomorphini, and all the rest to the third sub-family. Leconte, 
writing of the Coleoptera of North America, did not indicate the position 
of the extra-American genera. 
In 1880, + Kblbe, starting with the hypothesis that the land-beetles are 
later than the water-beetles, and that the points common to both are 
of primary value in classification, divided the family ‘ Carnivora ’ into six 
sections, which are further subdivided into groups. His arrangement, 
however, does not help us, and the placing of the family Cicindelidce as 
a simple subsection of one of his groups does not appear to be correct. 
In 1881, Dr. G. H. Horn, J reviewed the genera of the Carabidce of 
North America, and, in doing so, gave the following arrangement of the 
Adephagous families, which is followed in the present catalogue : — 
I. Metasternum with an ante-coxal piece, separated by a well- 
marked suture, reaching from one side to the other, and 
extending in a triangular process between the coxae. 
Antennae 11-jointed: posterior coxae mobile and simple ; habits 
terrestrial. 
Antennae inserted on the front above the base of the mandibles : 
Cicindelidce. 
Antennae arising at the side of the head, between the mandibles 
and the eyes : Carabidce. 
Antennae 10-jointed : posterior coxae fixod, and with large plates 
almost entirely concealing the abdomen : habits aquatic : 
Haliplidce. 
II. Metasternum with a very short ante-coxal piece, the suture in- 
distinct, posteriorly not prolonged between the coxae : habits 
aquatic : legs ambulatorial : anterior coxae globular : 
A mphizoidce. 
Legs natatorial : anterior coxae conical : Pelobiidce.
