about half the length, and thence strongly arcuate towards the apex, 
the anterior margin is straight, strongly reflexed, and the anterior 
part is somewhat hollowed, very little or not at all impunctate, and 
the deeply punctate posterior part is, with one exception (P. calva), 
clothed with long erect hairs, it is separated from the head by an 
arcuate suture reaching the anterior angles of the eyes which are 
incised by a narrow canthus, but in one species (P. bohemani) there 
is, in addition to the suture, a plain median keel; antennx 10-jointed 
in the male, the only sex known, the long club is 7-jointed; pro- 
thorax somewhat short, more attenuated laterally in the anterior 
than in the posterior part, and with both the anterior and posterior 
angles obtuse, not much convex, and fringed laterally with long 
hairs ; elytra slightly ampliated laterally in the posterior part, some- 
what depressed and covering the propygidium, faintly costulate and 
fringed laterally with long hairs; pygidium convex, drawn inwards ; 
abdominal segments seemingly free or partly free ; legs and claws of 
Camenta, from which this genus differs mainly by the hollowed 
clypeus, the drawn-in pygidium, the plainly more free abdominal 
segments, and the rounded anterior angles of the prothorax.
