294 INSECTA. 



distinguishes the Carabici of the third and last division of this sec- 

 tion, which, by the form of the body and the labrum, resemble those 

 of the preceding division. 



Ophonus, Zieg. Dej. 



The four anterior tarsi of the males strongly dilated, or evidently 

 wider, and generally furnished beneath with numerous and compact 

 hairs, forming a continuous brush; the penultimate joint is not bilo- 

 bate. The last joint of the exterior palpi truncated, or very obtuse. 



The body is very finely punctated above, and the thorax most fre- 

 quently cordiform, and truncated posteriorly(l). 



Stenolophus, Zieg. Dej. 



The Stenolophi only differ from the Ophoui in the form of the pe- 

 nultimate joint of the four anterior tarsi, at least in the males, and 

 in some even of the posterior; it is divided down to the base into 

 two lobes(2). 



AcuPALi'us, Lat. — Stenolophus, Dej. 



The four anterior tarsi of the males differing but little from the 

 intermediate joints; rounder, almost granular, and pilose; exterior 

 palpi terminating by a joint with a pointed extremity. 



They are very small insects, and seem to be allied to Trechus(3).

(4) This section, in the system of Dejean, forms his tribe of Carabiques Fero- 

 niens, in which — Spec. Gen. dcs Coleop. Ill — he has established several new 

 genera. Those male Feroiiioe, in which the two first joints of the two anterior 

 tarsi are alone dilated, are comprised in the genera Pogoxus, Caudiadeiius, Ba- 

 Biprs, and Patrobus. In the two first, the last joint of the labial palpi is oval or 

 pointed, whilst in the other two it is almost cylindrical, truncated at the extremity, 

 and slightly securiform. The second — Daptus ckloroticus, Fischer — differs from 

 the first in the thorax which is convex, cordiform, and narrowed posteriorly. In 

 Baripus, it is convex and almost oval. That of Patrobus is plane, narrowed pos- 

 teriorly and more or less cordiform. 



In the other male Feronise the three first joints of the anterior tarsi are dilated. 

 A first subdivision comprehends those FeroniK the hooks of whose tarsi are den- 

 tated, and among these the genus Dolichus is the one in which the tooth of the 

 middle of the emargination is simple, that is to say, entire. That which he names
