We now come to the Carahici, 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. 
Tricuognatha, 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 maxilla.’. ; 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, Fah. 
The Galcritae 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 maxilla;. 
The 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 i)roiongc’d than the external. The summit of the 
ligula is tridentate, and its paraglossae are very distinct. The 
emargination of the mentum is unidentatc. 
Some species, such as the Galerita occidentalism 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. — Calopikexa, Kliig, — Odocantha, Fab. 
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 unemarginate : its superior face is excavated 
for the reception of the next. The head is nearly oval j-. 
■\V'’e will t(;rminato this section with those in which the hooks of 
the tarsi arc 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 l)ase into two lobes ; the preceding ones are broad, 
and in the form of a heart or reversed triangle. The first joint of
