OocAMENTA (PSEUDOCAMENTA) TRANSVAALIA, n. spec. 
Black, with the abdomen red, piceous-red, or testaceous-red, the 
elytra, however, are often testaceous and more or less broadly infus- 
cate laterally ; the antenne are flavous in both sexes, the 10-jointed 
ones of the male have a long 7-jointed club the inner joint of which 
is slightly shorter than the one following, the 9-jointed antenne of 
the female have a 4-jointed, somewhat elongated club the joints of 
which are of equal length; the head and clypeus have the same 
shape as C. rufiventris, the gene are equally produced, the emargi- 
nation of the anterior part, the keel, and the suture are identical, the 
body, however, is much less ampliato-ovate, although distinctly 
convex in the hind part of the elytra, the punctures are deeper and 
very plain all over, and the costules of the elytra are visible. 
Length 64 mm. ; width 34-32 mm. 
Hab. Transvaal (Johannesburg, Pretoria, Lydenburg).

Mentum plainly amplated but not deeply constricted laterally 
towards the anterior part the angles of which are obliquely truncate 
but not angular, and the anterior margin plainly sinuate, inner face 
very convex and not visibly impressed in the anterior part, last joint 
of labial palpi ovato-acuminate ; maxille and palpi as in Ablabera 
and Camenta, but the former have five teeth only; clypeus semi- 
circular but incised laterally and deeply notched in the anterior part 
with the margins sharp and reflexed, it has an anterior arcuate ridge 
in the anterior part and another one at the junction with the fore- 
head, and the gene are greatly developed; the antennz are 10- 
jointed, and in the two species known the antennal club is long and 
7-jointed ; the general facies is that of Camenta, the claws also being 
alike, but it is differentiated by having two clypeal keels instead of a 
clypeal keel and a frontal suture.
