mucli the larger of the two, is common on the south 
coast. 
The Trachyscelina never have the last joint of the 
maxillary palpi liatchet-shaped ; their antennae are 
short, and the projection between their coxae is 
triangular. In Trachyscelis, a doubtful British genus, 
the antennae are shorter than the head and distinctly 
clubbed, and the eyes are sunk in the thorax, the sides 
of which, and the elytra, are fringed with long hairs. 
LnPhaleria the antennae are longer than the head, and 
not clubbed ; the eyes are more free, and there are no 
lateral fringes. P. cadaverina, a clear yellowish con- 
vex insect, with a suffused black patch in the middle 
of each elytron, occurs in decaying animal matter, and 
at the roots of maritime plants, in sandy places on the 
coast ; being common at Shoeburyness, at the roots of 
Sedum. 
The Bolitophagina, in company with several of the 
succeeding families, have their tarsi clothed on the 
under side with short hairs ; a similar structure being 
only exhibited by the Pedinina among the preceding 
families of this section. Their antennae are partly 
received in repose into a transverse furrow of the 
head; the labial palpi are widely separated at the 
base ; and the apical joint of the maxillary palpi is 
not hatchet-shaped. 
They live entirely in boleti, and are apparently 
gregarious. 
Bolitophagus crenatus, in which the eyes are divided, 
and the thorax crenulated at the sides, is dull black 
in colour, and has strong rows of punctures alter- 
nating with linear elevations, on its elytra. It is 
found in the north of England, and is much larger
