CLASS INSECTA, 



convex or gibbous, at least on the sides, and is dilated to- 

 wards the posterior angles in the manner of a lobe, going 

 either in a point, or triangular. These insects approximate to 

 the buprestides. 



Galea, Lat., 



The mandibles of which terminate in a single point, the 

 jaws present but a single lobe, the last articulation of the 

 palpi is globular, and the body almost cylindrical.* 



EucNEMis, Arh., 



In which the mandibles are bifid, and the jaws bilobate ; in 

 which the last articulation of the palpi is almost hatchet- 

 formed, and the body almost elliptical. -f* 



Occasionally the antennae, sometimes club-formed, are 

 lodged, at least in part, either in the longitudinal grooves 

 of the lateral edges of the praesternum, or in the fossets 

 situated under the posterior angles of the corslet. The 

 tarsi are often little palettes formed by the elongation of the 

 lower pellets ; or the penultimate articulation is bifid. 



Some, with filiform antennae, have the articulations of the 

 tarsi entire and without palettes underneath ; the two ante- 



* I have seen three species, and all of Brazil. One has great relations 

 with the Melads tuberculata of M. Dalman. (Anal. Entom.) The jaws 

 terminate by a very small and pointed lobe. 



-|- M. le Comte de Maunherheim has published a very fine monograph 

 of this sub-genus, of which an extract has been given, and the plates 

 re-produced in the third volume of the Annals of Natural Science. I 

 have added there a few observations on the too great extent which this 

 naturalist has given to this sub-genus. The species, which he names 

 Capucinus, is, according to me, the only one which ought to remain in it, 

 and such was, at first, the opinion of him who established it.
