the regular shape of the latter, scarcely exhibiting any appearance 
of the bipartite structure observable in Paussus; the extreme 
flatness and breadth of the antennz ; the broad legs; the very 
hairy basal joints of the tarsi; and, above all, the formation of 
the lower lip (labium) and its equal-jointed palpi, and the scapes 
upon which they are inserted,—cannot be regarded otherwise 
than as intimating a group generically distinct from the true 
Paussi. 
It may also be noticed, that the transverse impression near 
the base of the clava of the antenn:e appears to exhibit a ten- 
dency to an articulate structure, which is confirmed by the den- 
ticulations of its outer margin. This circumstance is particu- 
larly noticeable in P. aplustrifer, in which there are two of these 
impressions with their corresponding contractions or denticula- 
tions. 
The situation of the genus in the family appears to be between 
the species composing my second section of Paussus, and Cera- 
pterus. In their biarticulate antenne and the formation of their 
maxillary palpi they approach the former; and in the general 
habit of their bodies, as well as in the formation of the basal joints 
of their tarsi, and in the tendency to articulation exhibited in the 
clava of their antennz, they approximate to Cerapterus.
