138 INSECTA, 
TripLax, Tritoma, Fab. 
These Insects differ from the Erotyli in their antennz, which are 
almost granose, and terminated in a shorter and ovoid club, and in 
their maxille, of which the interior division is membranous, with a 
single and small terminal tooth. 
Those which are almost hemispherical or nearly round form the 
genus Tritoma of Fabricius. Such is the 
T. bipustwatum, Oliv., Col. 89, bis, I, 5. Black, with a 
large red spot at the base of each elytron. In the Boleti and 
Mushrooms *. 
Those which are oval or oblong form the genus TRiPLax proper of 
the same naturalist f. 
In the other the last joint of the maxillary palpi is elongated, and 
more or less oval. 
Laneuira, Lat., Oliv.—Trogosita, Fab. 
Where the body is linear and the antennal club consists of five 
joints. 
They are all foreign to Europe t. 
Puaracrus, Payk.—Anistoma, Illig., Fab.—Anrurisus, Geoff. Oliv. 
Where the body is almost hemispherical and the club of the an- 
tenn consists of but three joints’§. 
On flowers and under the bark of trees. 
In the remaining Clavipalpi all the joints of the tarsi are simple, 
and the body is nearly globular. They form the genus 
Acaruipium, I/lig—Anisoroma, Fab.|| 
In the fourth section of the Coleoptera, that of the Trimra, there 
are but three joints to all the tarsi. 'The Trimera form three families. 
Those of the two first are closely related to the last of the Tetramera. 
Their antennz, always composed of eleven joints{, terminate in a 
club formed by the three last, which is compressed, and in the form 
of a reversed cone or triangle. The first joint of the tarsi is always 
very distinct; the penultimate is usually bilobate, and the last, which 
presents a knot at base, is always terminated by two hooks. The 
elytra entirely cover the abdomen, and are not truncated. The last 
of the Trimera, or those of the third family, in this character, as well

may have been some mistake.
