196 CLASS INSECTA. 



In some, the corslet is sensibly wider than it is long, in 

 the form of the segment of a circle, or a heart broadly and 

 transversely truncated behind. 



There are some in which the middle of the hind edge of the 

 corslet is elongated backward. Such are 



Lebia, Lat. Lebia, Lamprias, Bon. 



The exterior palpi are terminated by a somewhat larger 

 articulation, nearly cylindrical, or ovaliform, and truncated 

 behind. The first four articulations of the tarsi are nearly 

 triangular, and the fourth is more or less bifid or bilobed. 



These insects are prettily coloured. The commonest species 

 in Europe is Carabus cyanocephalus^ Lin., Fab. The Bu~ 

 preste blue, and corslet rouge, Geoff. ; Panz. Faun. Insect. 

 Germ. 65. 5; Hist. Nat, de Coleopt. d'Eur., fasc. III. 12. 7. 

 Its body is from two lines and a half to three lines and a half 

 long. It is blue or green, very shining above, with the first 

 articulation of the antennae, the corslet, and the tarsi of a 

 fulvous red, the extremity of the thighs black, and the elytra 

 dotted, marked with light dotted striae. 



Another species of our environs is Carabus hcBmorrhoi- 

 dalts, Fab. Hist. Nat. de Coleopt. d'Eur., fasc. III. 13. 8., 

 which is scarcely more than two lines long, whose body is 

 fulvous, with the elytra black, and terminated by a yellowish 

 fulvous spot ; they have some light punctated striae, and two 

 more distinct points near a third at the commencement of the 

 suture.* 



In the ensuing the corslet terminates posteriorly by a 

 straight line, without advancing at the middle. 



Plochionus, Dej. 

 Which have the antennae nearly grained, the last articulation
