COLEOPTERA. 375 



We now come to the Carabici, very analogous to the preceding 

 ones in their divisional characters, but removed from them by the 

 form of their tarsi. The four first joints, or at least those of the 

 anterior tarsi of the males, are greatly dilated and bifid ; the penul- 

 timate of all, and in both sexes, is always emarginated or dilated. 

 The exterior palpi and the first joint of the antennae always long. 



Tkichognatha, Lat. 



Ultimate joint of the exterior palpi in the form of a reversed cone, 

 and elongated : a hairy triangular projection on the exterior side of 

 the maxillae ; very long palpi ; labrum bicrenate, with three obtuse 

 teeth ; summit of the ligula armed with three spines ; the four poste- 

 rior tarsi not dilated, at least in the females. The type of the genus 

 (T. marginipennis) was brought from Brazil by the celebrated bo- 

 tanist M, de Saint Hilaire. 



Galerita, Fab. 



The Galeritae differ from the preceding subgenera in their exte- 

 rior palpi, of which the last joint is triangular or securiform, and in 

 the non-dilatation of the exterior side of the maxillae. 



Tlie two anterior tarsi of the males are widened ; the emargina- 

 tions of the four first joints are acute, and their internal divisions are 

 larger and more prolonged than the external. The summit of the 

 ligula is tridentate, and its paraglossee are very distinct. The 

 emargination of the mentum is unidentate. 



Some species, such as the Galerita occidentalis, Dej. ; G. afri- 

 cana. Id., by their oval head, and narrower and more elongated 

 thorax, form a particular division. Most of them belong to 

 America *. 



CoRDisTES, Latr. — Calophcena, Klilg, — Odocantha, i*a6. 



The exterior palpi filiform and terminated by an oval and pointed 

 joint. 



The four first joints of all the tarsi dilated, and the first In the form 

 of a reversed and elongated cone ; lobes of the two following ones 

 equal, straight, and pointed ; the fourth in the form of a heart or 

 reversed triangle, and uncmarginate : its superior face is excavated 

 for the reception of the next. The head is nearly oval f . 



We will terminate this section with those in which the hooks of 

 the tarsi are dentated beneath in the manner of a comb, and com- 

 mence with such as have their oval or ovoid head separated from 

 the thorax by a sudden and marked strangulation forming a sort of 

 knot or patella. The penultimate joint of their tarsi is always di- 

 vided down to its base into two lobes ; the preceding ones are broad, 

 and in the form of a heart or reversed triangle. The first joint of
