Cucusus, Fab. 
We distinguish 
Cucusvs, properly so called, 
Where the antenne, 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 *, 
Denpropuacus, Gyll_—Cucusus, Fab. Payk. 
Where those organs are generally formed of elongated and cylin- 
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 fF. 
Exveorota, Lat.—Brontes, Fab. 
Where the antennz 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 f. 
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 ona 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 antenne 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 Parandre, 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. Jt 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.
