COLEOPTERA. 139 
as in several others, approximate to the Pentamerous Brachelytra, 
and some other Coleoptera of the same section, such as the Mastigi 
and Scydmeni; their habits are also very different from those of the 
other Trimera. 
FAMILY I. 
FUNGICOL. 
In our first family of this section we observe antenne longer than 
the head and thorax united, an oval body, and a trapezoidal thorax. 
The maxillary palpi are filiform or a little thicker at the end, but are 
terminated by a very large and securiform joint. The penultimate 
joint of the tarsi is always deeply bilobate. 
This family may be reduced to one great genus. 
EuMORPRUS. 
In some the third joint of the antenne is much longer than the 
preceding and following ones. Such are 
Eumorpuus, Web. Fab., 
Or the Eumorphi proper, where the club of the antenne is abrupt, 
compact, strongly compressed, and in the form of a reversed triangle. 
The maxillary palpi are filiform, and the two last joints of the labials 
united form a triangular club. } 
They are all peculiar to America and the East Indies *. 
Dapsa, Zieg. 
Where the club of the antenne is narrow, elongated, and composed 
of joints, laterally remote, the last of which is almost ovoid f. 
In the others the third joint is but little longer than that of the pre- 
ceding and following ones. 
Several species are indigenous to Europe, and live in the Ly- 
coperdons, or under the bark of the Birch and some other trees, 
Enpomycuus, Web. Fab. 
Where the four palpi are thickest at the extremity; the three last 
joints of the antennee are separated laterally, are larger than the pre- 
ceding ones, and compose a club in the form of a reversed triangle {. 
Lycorerpina, Lat—Enpomycuus, Fab. 
Where the maxillary palpi are also filiform; the last joints of the 
labials is larger than the preceding ones, and almost ovoid; the

should be referred to Dapsa.
