PARACAMENTA CALVA, 0. spec. 
A little smaller than P. verticalis, and more reddish; the clypeus 
is of the same shape but there is a broader smooth space in the 
anterior part, the posterior is punctate but not scabrose and 
without erect hairs; the prothorax and the elytra are similar in 
shape and sculpture, but are fringed laterally with short, some- 
what remote hairs; the under side is equally hairy; the inner 
joint of the antennal club is a little shorter than the one following ; 
the third joint of the pedicel is long and somewhat aculeate inwardly 
in the median part. 
Length 6-7 mm.; width 3-35 mm. 
Hab. Transvaal (Zoutpansberg). 
IDAICAMENTA, n. gen. 
Mentum of Camenta, maxille with five teeth only, as in Diplo- 
bothris, three superposed ones in the upper and two in the inner side, 
last joint of maxillary palpi long and very plainly fusiform ; clypeus 
shorter than the head and declivous, parallel laterally, deeply incised, 
at two-thirds of the length, much narrowed thence, but still parallel, 
as far as the very slightly rounded apical angles, anterior edge 
broadly emarginate, strongly recurved somewhat in the manner 
of a Trochalus, hollowed in the anterior part, the hollowness being 
bounded by an impressed line, sub-vertical above that line as far as 
the median keel which is sub-arcuate and reaches from side to side, 
plainly declivous thence to second arcuate keel separating it from 
the head which is plane, the gene are strongly developed, but 
oblique and not rounded or ampliated in front of the eyes, 
the antennze are 10-jointed in the male, the only sex known, 
the 10-jointed club is extremely long, and curved, the third joint 
of the pedicel long and aculeate inwardly near the base; facies, 
sculpture, and build of Psewdocamenta, of which it has also the 
claws, the drawn-in pygidium, and the free or nearly free abdominal 
segments, but from which it differs by the altogether different shape 
of the clypeus, which resembles that of a Trochalidous melolonthid. 
IDEHCAMENTA JUCUNDA, n. spec. 
Pale testaceous or testaceous-red, antennex flavous; the hollowed 
and declivous parts of the clypeus is almost impunctate, but the space 
between the two keels and the head is covered with deep, closely set, 
but not quite contiguous punctures; joints of the club equal, as 
long as the prothorax, the third one of the pedicel with a plain
