74 INSECTA. 
those in which the thorax is destitute of a horn, some are ap- 
terous *, 
The two last tribes of this family, and of the section of the Hete- 
romera present certain common characters, such as mandibles termi- 
nating in a simple point; the palpi filiform, or merely slightly 
thickened towards the extremity, but never ending in the securiform 
club; the abdomen soft; the elytra flexible, and in most of them 
epispastic ; all the joints of the tarsi, some few excepted, entire, and 
their hooks generally bifid. Ina perfect state they are all herbivor- 
ous, but several, in their first state, or that of larvee, are parasitical. 
The Hortaues, composing the fifth tribe, differ from those which 
constitute the sixth, or the CANTHARIDLA, in their hooks, which are 
indented and accompanied (each) by a serrated appendage. These 
Insects have filiform antennz, as long, at most, as the thorax, a 
small labrum, strong and salient mandibles, filiform palpi, square 
thorax, and very robust posterior legs, at least in one of the sexes. 
The metamorphoses of the Spotted Horia, an Insect inhabiting the 
Antilles and South America, are described in the fourteenth volume 
of the “ Transactions of the Linnzan Society of London ;” its larva 
destroys that of a species of Xylocopa—Teredo; X. morio, Fab.— 
which perforates the dead trunks of trees, and deposits its ova there 
in the manner of other Xylocope. The author of the Memoir 
alluded to, suspects that the larva of this coleopterous Insect lives on 
the provisions destined for the other, which consequently is starved 
to death. 
This tribe is composed of the genus 
Horta, Fab. 
These Insects inhabit the intra-tropical countries of South America 
and of the East Indies. One of these species, from the latter, is re- 
moved from all others by its head, which is narrower than the tho- 
rax, and by its posterior thighs which are strongly inflated, a cha- 
racter which perhaps only belongs to one of the sexes. It is the 
type of my genus Cissites +. 
The sixth and last tribe, that of the Canruaripim, is distinguished 
from the preceding one by the hooks of the tarsi, which are deeply 
cleft, and seem to be double. The head is usually large, wider, and 
doubled posteriorly. The thorax is commonly narrowed behind, and 
approaches the form of a truncated heart; in others it is almost

tulata of Fabricius is a Notoxus.
