192 CLASS INSECTA. 



Drypta, Latr. Fab. 



All the known species belong to the old continent, or New 

 Holland. Two are to be found in Europe, always on the 

 ground. The most common is Drypta emarginata. Fab. 

 Clairv. Entom. Helv. II. xvii. Hist. Nat. des Coleops. 

 d'Eur. fasc. II. x. 1. It is about four lines in length, of a 

 beautiful azure blue, with the mouth, the antennae, and the 

 feet, fawn-colour. The extremity of the first articulations 

 of the antennae, and the middle of the third, are blackish. 

 The elytra have punctuated striae. It is more common in 

 the south of France than in the north ; M. Blondel (the 

 son) has, however, found it in abundance, in a locality, in 

 the neighbourhood of Versailles. — N.B. For the other species 

 see Hist. Nat. des Coleop. d'Eur. II. x. 2. and Spec. Gen. 

 de M. le Comte Dejean, tom. I. pag. 182. 



To those succeed carabici, very analogous to the preceding 

 in their divisionary characters, but which are removed from 

 them by the form of the tarsi. The first four articulations, 

 or at least those of the anterior tarsi of the males, are very 

 much dilated and bifid. The penultimate of all is, in the 

 two sexes, constantly emarginated or dilated. The external 

 palpi, and the first articulation of the antennae, are always 

 long. 



Tricognatha, Latr., 



Have the last articulation of the external palpi in the form 

 of a transverse and elongated cone, and a triangular and 

 hairy projection at the external side of the jaws. The palpi 

 are very long. The labrum presents two crenulations and 

 three obtuse teeth. The summit of the tongue is armed with 

 three spines. The four posterior tarsi are not dilated, at 

 least in the females. The insect (marginipe7inis) serving as 

 type, was brought from Brazil by the celebrated botanist, 

 M. de Saint Hilaire.
