56 INSECTA. 
Phaleria by the linear form of their body, and their thorax, which 
forms a long square or is almost cylindrical. They are the 
Hypornievs, Fab.—lIrs, Oliv. 
They are found under the bark of trees *. 
There, the antenn, exposed at base or but very slightly covered, 
are abruptly terminated by a large oval or ovoid perfoliate club, of 
at least four joints, the second of which, in those where it consists 
of five, is very small. The body is ovoid, or almost hemispherical, 
and convex. In 
Tracuysceiis, Lat., Dej., 
The antennex, hardly longer than the head, terminate in an ovoid 
club of six joints; all the tibie are broad, triangular, and fitted for 
digging, and the body short and most usually hemispherical. They 
bury themselves in the sand on the sea shore f. 
Letopes, Lat.—Anisotoma, Illig., Fab. 
The body similarly short and convex ; but the antennz, as long as 
the head and thorax, are terminated by an oval club of five joints, the 
second of which is smaller. The tibie are narrow, elongated or 
but slightly dilated ; the four anterior ones, at least, are spinous f. 
Terratoma, Herbst., Fab. 
The body somewhat more elongated than that of the preceding 
Insects, ovoid, less elevated above; all the tibize narrow and without 
spines; the antennz as long as the head and thorax, and terminated 
by an oval club of four joints §. 
Sometimes the antenne. always terminated by a perfoliaceous club 
of five or three joints, the preceding ones of which are almost in the 
form of a reversed cone, or slightly dilated on the outer side in the 
manner of a tooth, are arcuated, or somewhat curved. The body is 
ovoid, very unequal above, or the elytra are deeply punctured and 
striated. The thorax is depressed laterally, and the edges of this 
marginal border are dentated; it is separated posteriorly on each 
side by a remarkable hiatus. The palpi are filiform, or slightly en- 
larged at the extremity, as in Phaleria and Diaperis. The head of 
the males is frequently horned. ‘They are also found in the fungi 
on trees: they form the genus 
Exepona, Lat—Boierorxacus, Fab., and most others. 
M. Ziegler and Count Dejean only refer to it those species in 
* Hypophleus castaneus, Fab.; Panz., Faun. Insect. Germ., XII, 13 ;—dH. line- 
aris, Fab.; Panz., Ib., VI, 16 ;—H. fasciatus, Panz., Ib., VI, 17 ;—H. bicolor, 
Fab.; Panz., Ib., XII, 14 ;—H. pini, Ib., LXVII, 19. In Hypophleus and Ele- 
dona, M. Leon Dufour found but four biliary vessels ; in Diaperis there are six.
