56 INSECTA. 



Phaleria by \he lineai* form of their body, and tbeir tborax, which 

 forms a long square or is almost cylindrical. They arc the 



Hypophl^us, Fab. — Ips, Oliv. 



They are found under the bark of trees *. 



There, the antennae, 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 



Trachyscelis, Lat., Dej., 

 The antenna;, hardly longer than the head, terminate in an OA'oid 

 club of six joints; all the tibire are In-oad, triangular, and fitted for 

 digging, and the body short and most usually hemispherical. They 

 bury themselves in the sand on the sea shore ■[. 



Leiodes, Lat. — Anisotoma, Illig., Fab. 

 The body similarly short and convex ; but the antennae', as long as 

 the head and thorax, are terminated by an oval club of five joints, the 

 second of which is smaller. The tibiae are narrow, elongated or 

 but slightly dilated ; the four anterior ones, at least, are spinous J. 



Tetratcma, Herbst., Fab. 



The body somewhat more elongated than that of the preceding 

 Insects, ovoid, less elevated above ; all the tihipe narrow and without 

 spines ; the antennae as long as the head and thorax, and terminated 

 by an oval club of four joints §. 



Sometimes the antennse, 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 pimctured 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. Tjie palpi arc 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 



Eledona, Lat. — Boletophagus, Fab., and most others. 

 M. Ziegler and Count Dejean only refer to it those species in 



* Hi/pojihlmis caslaneiis, F&h.; Panz., Faun. Insect. Germ., XII, 13; — H. line- 

 «m, Fab. ; Panz., lb., VI, \6 ;—H. fasciatus, Panz., lb., VI, 17 ;— iJ. bicolor, 

 Fab.; Panz., lb., XII, 14 ; — H. pini, lb., LXVII, 19. In Hypophlffius and Ele- 

 dona, M. Leon Dufour found but four biliary vessels ; in Diaperis there are si.Y.
