rior tiblfe • the first joint of the antennae elongated, forming a re- 
versed cone, and the second shorter than the third; summit of the 
hgula straight, without any projection ; thorax almost in the shape of 
a cup, nearly as long as it is hroad, and without posterior projections- 
the lahrum dentated. ’ 
Some are apterous and have an oval abdomen * The latter is 
oval in others, and truncated at base ; these are furnished with wings. 
A ncAV species has been discovered in Sicily by M. Lefevre. All the 
others, both of this and the preceding division, inhabit northern 
Africa or the East Indies 
1 he third subgenus, in its moniliform antennae, the teeth on the 
exterior side of the two first tibiae and in the ordinary proportions of 
the mentum, evidently approximates to Scarites. 
Carenum, Bon. 
Straight maxillae without a terminal hook ; summit of the ligula 
rounded ; ultimate joint of the exterior maxillary palpi enlarged and 
double the length of the preceding one. 
The only species known — Scarites cyaneus. Fab. — inhabits 
New Holland. 
None of- the other Carabici of this section exhibits labial palpi ter- 
minated by a larger and securiform joint .- the last is in the form of 
a reversed and elongated cone, or almost cylindrical and smaller at 
base; the same joint of the exterior maxillary palpi is also nearly 
cylindrical ; all these palpi are about the same thickness throughout, 
or sometimes attenuated at the extremity. 
A first very natural subdivision, which comprises the Scarites of 
Fabricius, the cyaneus excepted, consists of bipartite Carabici, whose 
anterior legs are palmated, or at least. digitated at the end, that is to 
say, terminated exteriorly by a long point in the form of a spine, 
opposite to a very stout internal spur. Their antennae are granose ; 
the second joint as long as the following one, and frequently longer. 
The mandibles, those of a small number excepted, are stout, project- 
ing, and angular, or dentated on the internal side. The lahrum is 
very short, transversal, and crustaceous. The ligula is most fre- 
quently entirely corneous, bristled with hairs or cilia, lu’oadly cmar- 
ginate or widened at the summit, and with projecting lateral angles. 
Some have very strong, projecting, and "usually dentated mandi- 
bles; the anterior margin of the crustaceous lahrum A'ery dentate, 
the ligula short, not extending beyond the mentum, entirely horny 
or crustaceous, bristled with hairs, and widened at the superior mar- 
gin. Their anterior tibiae are always palmate. The species gene- 
rally are large. 
One of these subgenera.
