210 CLASS INSECTA. 



The absence of a sensible tooth in the emargination of the 

 chin distinguishes the carabici of the third and last division 

 of this section, and which, from the form of the body and the 

 labrum, resemble otherwise those of the preceding division. 



Ophonus, Ziegl. Dej. 



The males of which have the four anterior tarsi strongly 

 dilated, or sensibly wider, and generally furnished under- 

 neath with numerous and crowded hairs, forming a continu- 

 ous brush. The penultimate articulation is not bilobate. 

 The last of the external palpi is truncated or very obtuse. 



The under part of the body is very finely punctuated. 

 The corslet is most frequently heart-formed, and truncated 

 posteriorly. 



Stenolophus, Zieg. Dej. 



Which differ from the Ophoni only in the form of the last 

 articulation but one of the four anterior tarsi, at least in the 

 males, and even of the posterior in some. It is divided as 

 far as its base into two lobes.* 



AcuPALPus, Lat. Stenolophus, Dej. 



In which the four anterior tarsi of the males differ little from 

 the posterior, with the intermediate articulations rounded, 

 almost grained, and hairy. The external palpi terminate 

 with an articulation, pointed at the end. 



These Carabici are very small, and appear to be connected 

 with trechus. They are the stenolophi of the Comte Dejean, 

 with the exception of the preceding. Among others we may 

 cite the Carabus Meridianus of Linnaeus and Fabricius, and 

 the C. Vespertinus of Panzer, XXXVII. 21.
