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

 by an oval club of four joints(l). 



Sometimes the antennae, 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 



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



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

 which the club of the antennae is formed by the last five joints, and 

 the preceding ones are slightly securiform(2). 



Those, in which the three last alone form the club, and the three 

 preceding ones, are in the form of reversed cones, without an inte- 

 rior projection, compose the genus Coxelus(3). 



Our second tribe of the Taxicornes, the Cossyphenes, 

 consists of Insects analogous in form to the Peltis of Fabri- 

 cius, and to several Nitidulae and Cassidse : it is ovoid or 

 sub-hemispherical, and overlapped in its contour by the di- 

 lated or flattened sides of the thorax and elytra ; the head is 

 sometimes entirely concealed under that thorax, and at others 

 received into an anterior emargination of the same part. The 

 last joint of the maxillary palpi is larger than the preceding 

 ones, and securiform. 



This tribe is composed of the genus 



CossYPHUs, Oliv. Fab. 

 Some of them have a flat body, of a solid consistence, in the form of

 these Insects.
