2 E. T. Atkinson— Catalogue of the Carabidse. [Snpplfc. 



Following the suggestions of the later authors, Leconte divided the 

 whole family into three sub-families, formed thus : — ■ 

 Middle coxse distant ; 



EDimera of the mesonotum reaching the coxse ... 1. Carabid.,e. 

 Epimera of the mesonotum not reaching the cosse ... 3. Harpalioe. 

 Middle coxse contiguous ... ... ... 2. Oz^nio^e. 



In the Carabidce, he placed the tribes Omophronini, Hiletini, C'arabini, 

 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, t Kolbe, 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 sis 

 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-cosal piece, separated by a well- 

 marked suture, reaching from one side to the other, and 

 extending in a triangular process between the coxae. 

 Antenuse 1 1 -join ted : posterior cosse mobile and simple; habits 



terrestrial. 

 Antennse inserted on the front above the base of the mandibles : 



Ciciridelidce. 



Antennae arising at the side of the head, between the mandibles 



and the eyes : Carabidce. 



Antenna? 10-jointed : posterior coxse fixed, and with large plates 



almost entirely concealing the abdomen : habits aquatic : 



Haliplidcv. 

 II. Metasternum with a very short ante-coxa! piece, the suture in- 

 distinct, posteriorly not prolonged between the coxse : habits 

 aquatic : legs ambulatorial : anterior coxse globular : 



Ampkizoidce. 

 Legs natatorial : anterior coxse conical : Pelobiidce.
