COLEOPTERA. 
441 
In the remaining Melyrides the maxillary palpi are terminated by 
a larger and securiform joint. This character, together with the 
shortness of the first joint of the tarsi, and some other considerations, 
seems to approximate them to the Insects of our next tribe. They 
form the 
Pelocophorus, Dej., 
Who arranges them with the tetramerous Coleoptera *. 
The fourth tribe of the Malacodermi, that of the Clerii, is distin- 
guished by the ensemble of the following characters. Two of their 
palpi at least project and are clavate. The mandibles ai’e dentated. 
The penultimate joint of the tarsi is bilobate, and the first is very short 
or but slightly visible in several. The antennae are sometimes nearly 
filiform and serrated, and at others insensibly enlarged near the ex- 
tremity. The body is usually cylindrical, the head and thorax nar- 
rower than the abdomen, and the eyes emarginated. 
Most of these Insects are found on flowers, the remainder on the 
trunks of old trees or in dry wood. Such of the larvae as are known 
are carnivorous. 
This tribe will comprise the genus 
Clerus, Geoff. 
The tarsi of some, viewed from above and underneath, distinctly 
exhibit five joints. The greater part of their antennae is always 
serrated. 
Of these, some have the maxillary palpi filiform, or slightly en- 
larged near the e.xtremity. 
Cylidrus, Lat. 
Mandibles long and much crossed, terminating in a simple point, 
with two teeth on the internal side; four first joints of the antennae 
cylindrical and elongated ; the six following ones formed like the 
teeth of a saw, and the last oblong; the palpi terminated by an elon- 
gated joint; that of those attached to the maxillae cylindrical, and 
the same of the labial palpi, rather thicker and forming a reversed 
cone ; penultimate joint of the tarsi distinctly bilobate. The head is 
elongated. 
The only species known — Trichocles cyaneus, Fab. — inhabits 
the Isle of France. 
* Catalogue, &c., Dej., p. 115; Notoxus lUigeri, Schoen., Synon. Insect., I, 
2, p. 53, IV, 7, a. I refer to the same division of Melyrides, a new subgenus which 
I will call Diglobicerus. The antennae consist of hut ten distinct joints, of which 
the two last are larger and globular. It is founded on an insect sent to me by M. 
Lef^bure de Cerisy.
