66 INSECTA. 
The fourth tribe, that of the CApeMERITEs, is connected with the 
third by several characters, such as having the antennze inserted near 
the eyes, and their origin exposed, the mandibles bifid at the end, the 
penultimate joint of the tarsi bilobate, and the maxillary palpi termi- 
nated by a larger and securiform joint; but if we except the Nothi, 
approximated by the form and breadth of the thorax, and by some other 
characters, to certain Heteromera of the preceding tribe, and yet dis- 
tinguished from them by their strongly inflated posterior thighs, and 
their bicleft tarsial hooks, the (Edemerites present a union of charac- 
ters which will not allow us to confound them with the other Hetero- 
mera. The body is elongated, narrow, almost linear, and the head 
and thorax are somewhat narrower than the abdomen. The antennz 
are longer than the two latter, serrated in some—Calopus—filiform 
or setaceous, and composed of long and almost cylindricrl joints in 
the others; the anterior extremity of the head is more or less pro- 
longed into a little snout, and somewhat narrowed behind; the eyes 
are proportionally more elevated than in the preceding Heteromera. 
The thorax is at least as long as it is broad, almost square, or nearly 
cylindrical, and slightly narrowed behind; the elytra are linear or 
subulate posteriorly, and frequently flexible. These Insects are allied 
to Telephorus and Zonitis. 
M. Leon Dufour has discovered in the GEdemerites two very sim- 
ple, flexuous, and floating salivary vessels *, as well as a paunch 
formed by a lateral crop, furnished with a neck or pedicle. They 
are the only Coleoptera in which he has observed it. These Insects 
are found on flowers or trees. Their metamorphoses are unknown. 
These Hetoromera will be comprised in a single genus, the 
QCipremeraA, Oliv. 
Here, where the antennz are always short, inserted into an emargi- 
nation of the eyes, and simple, the posterior thighs are inflated, at 
least in one of the sexes, the thorax is as wide as the base of the ab- 
domen, and wider than the head; the hooks of the tarsi are bifid.

Where the maxillary palpi are terminated by a large, securiform 
* The Mordellones present the same character. In a more natural series it 
would perhaps be necessary to place the Horiz, which also have the posterior thighs 
inflated, immediately after Zonitis and Sitaris, then pass to the G2demerites and 
Mordellones, and terminate the Heteromera with the Notoxi or Anthicus of Fabri- 
cius, Insects evidently connected with the Mordellones by the Scraptie. In my 
Gener. Crust. et Insect., I have placed the Gidemerites at the end of the same sec- 
tion. The Rhebi of M. Fischer, although tetramerous, are allied in many respects 
to the Nothi and Gtdemere. The Xylophili, also tetramerous, are however closely 
related to the Notoxi.
