This robust, dull black insect has the head very broad (fig. 8 seen beneath ; 8 seen sideways), ^vith the
fore margin slightly reflexed. The basal joint of the antennte is very large and triangular, the second joint
being inserted near the middle of its under surface. The mandibles (fig. 8 c) are very broad, the inner basal angle
being much produced internally, The maxillaB have the two lobes produced into very sharp and slender tcetli
(fig. 8i/). The mentum is very broad, strongly angulated below the middle (as seen in fig-. 8 4). The labium
has two setose lobes applied to the inner surface of the base of the meutum, and the labial palpi arise far apart,
near the lateral margins of the mentimi (fig. 8 e). The presternum is armed with a short slightly deilexed
spine in front of the anterior cosie (fig. 8i), and the mesosternal process is very short, flat, and acuminated
behind, meeting the advanced point of the centre of the front of the mesosternum (fig. 8 f ) . The body beneath
is black and glossy ; the sides of the metasternuni marked with small oblique striolai ; the abdomen beneath is
convex ; the pygidium convex, with a very slight central, oblong, scarcely raised tubercle ; the segments finely
but distantly punctured.

The remarkable and unique insect, which forms the type of this genus in its robust form and teeth of
the maxillre, approaches Oplostomus, from which the armature of the bead and prothorax, the shape of the
meutum, and the tridentate anterior tibiifi at once remove it; in several of the latter characters it approaches
Cyclidius.

The broad flattened form of the unique type of this genus, with its obscure colour and almost impunctate
surface, with the broad head and corresponding broad mentum entirely closing the month beneath, will readily
distinguish it from the other genera of the family, although most nearly allied to Oplostomus.

Species America; tropica? ineolic.
The insects on which I have formed this genus are natives of the tropical parts of America, whilst those
of the Genus Genuchus, to which they are most nearly allied, are inhabitants of Africa. Erom the American
Cremastocheili and Psilocnemis they ditTer in the narrow form of the body and much narrower mentum.
