Cucujus, Fab. 

 We distinguish 



Cucujus, properly so called, 

 Where the antennae, much shorter than the body in several, are 

 composed of obconical or turbiniform and almost granose joints, the 

 first of which is shorter than the head *. 



Dendrophagus, Gijll. — Cucujus, Fab. Payk. 



"Where those organs are generally formed of elongated and cj'lin- 

 drical joints, the first of which is longer than the head, and the se- 

 cond and third are shorter than the following ones. The labial palpi 

 terminate in a club f . 



Eleoiota, Lat. — Bronte«;, Fah. 



Where the antennae are analogous, but where the third joint is as 

 long as the following one, and all the palpi are smaller at the extre- 

 mity. The mandibles of the species most common in Fiance, the 

 flavipes, and on which M. Dufour has made some anatomical ob- 

 servations, are furnished, in the males, with a long and acute pro- 

 longation resembling a horn |. 



FAMILY IV. 



LONGICORNES. 

 Here the under part of the three first joints of the tarsi is furnished 

 with a brush ; the second and third are cordiform ; the fourth is 

 deeply bilobate, and there is a little nodule resembling a joint § at 

 the base of the last. The ligula, placed on a short and transversal 

 mentum, is usually membranous, cordiform, emarginated, or bifid, 

 corneous, and forming the segment of a very short and transversal 

 circle in others ||. The antennae are filiform or cetaceous, most 

 commonly as long as the body at least; they are sometimes simple 

 in both sexes, and sometimes serrated, pectinated or flabelliform in 

 the males. The eyes of a great many are reniform and surround 

 them at base. The thorax is trapezoidal or narrowed before, in

§ The Parandrae, in this respect, perfectly resemble the Longicornes, and if this 

 little nodule be considered as a true joint, not only this family, but the following one 

 likewise, would belong to the section of the Pentamera. It may in fact represent 

 the fourth joint of the latter, but as it has no peculiar motion, it is understood as 

 forming part of the next.
