212 CLASS INSECTA. 



mating to the amara of H. Bonelli, but are removed from the 

 other carabici of this division by the mode of dilatation pro- 

 per to the two anterior tarsi of the males. The first two arti- 

 culations only, the radical of which is the largest, are dilated. 

 The following two are small and equal ; their body is gene- 

 rally more oblong than those of the amara. These insects 

 appear to inhabit almost exclusively the shores of the sea, or 

 the banks of salt lakes.* 



Tetragonoderus, Dej. 



The anterior tarsi of the males are proportionally less dilated 

 than in the following, • their first articulations being more 

 narrow, and more elongated, and rather in the form of a 

 reversed cone than in that of a heart. These insects are 

 peculiar to South America. •!• 



Feronia, Lat. • 



In which the anterior tarsi of the male have their first three 

 articulations strongly dilated, in the form of a reversed heart, 

 and of which the second and third are rather transverse than 

 longitudinal. 



This sub-genus will comprehend a great number of generic 

 sections, indicated in the catalogue of the collection of 

 M. le Comte Dejean, such as the following : Amara, P(V- 

 cilus, Argidor, Omaseus, Platysma, Pterostichus, Abax, 

 Steropus, Percus, Molops, Cophosus. This learned ento- 

 mologist has since acknowledged, in the third volume of his 

 species, the impossibility of determining them, and with the 

 exception of the first, which he still preserves, he unites the
