ORDER COLEOPTERA- 221 



Ctenipes, Lat. Lcemosthenus, Bon. 



Whose body is straight and elongated, with the corslet in 

 the form of a heart, narrowed and truncated posteriorly. 

 The third articulation of the antennae is elongated.* 



Calathus, Bon. 



In which the body is oval, arched above, with the corslet 

 square, or trapezoid, and broader posteriorly. -}- 



The others have the labial palpi terminated in a club- 

 form, or in that of a reversed cone, and the corslet almost 

 orbicular. 



Taphria, Bon. Synuchus, Gyllen. 



The emargination of the mentura is bidentated, as well as 

 in the preceding sub-genus (Carabus vivalis, llig. Panz., 

 ibid, xxxvii. 19). 



The fifth section, that of Patellimani, is distinguished 

 from the preceding only by the manner in which the two 

 anterior tarsi are dilated in the males. The first articula- 

 tions (generally the first three), sometimes square, some- 

 times partly in this form, and the others in the form of a 

 heart, or reversed triangle, but always rounded at their extre- 



* The Sphodri, janthinus, complanatus, and many others of M. le Comte 

 Dejean, which are distinguished from the true Sjjhodri, by the shortening 

 of the third articulation of the antennae, and the articulations of the 

 crotchets of the tarsi. These two sub-genera are confounded together 

 almost insensibly. M. Fischer has figured many species of one and the 

 other under the generic denomination of Sphodrus, in the second volume 

 of his Entomology of Russia.
