CAMENTA (HEMICAMENTA) TUMIDA, n. spec. 
This species, the male of which is unknown to me, but will prob- 
ably prove to be much more elongated, will be easily recognised by 
its rotund facies, which is much more convex than that of the female 
of C. caffrina. Head and prothorax piceous, elytra chestnut-brown; 
clypeus incised laterally past the median part, and narrowed thence 
to the sharp anterior angles, which, however, do not project, faintly 
bi-sinuate in the anterior margin, nearly smooth in front, but deeply 
punctured between the clypeal keel and the suture, head covered 
with nearly contiguous round punctures ; prothorax with sub-con- 
tiguous round punctures, outer margins serrulate in the posterior 
parts; elytra very convex, with the intervals between the very 
plainly raised costules filled with equi-distant, round, deep punctures. 
Length 11-124 mm. ; width 64-7 mm. 
Hab. Cape Colony (Albany, Seymour). 
CAMENTA (EMPECAMENTA) RHODESIANA, h. spec. 
Chestnut-red, clothed on the upper side with a somewhat dense, 
erect, light fulvous pubescence; anterior part of the head ferrugi- 
nous, clypeus not incised and narrowed laterally, but very deeply 
notched in the anterior part the angles of which are much rounded, 
the clypeal keel is sinuate and highly raised, the clypeal suture is 
almost obliterated, the anterior part of the clypeus is smooth, the 
posterior and also the head roughly foveate ; the 4-jointed antennal 
club of the male is very long, and the joints equal, the sixth joint of 
the pedicel is compressed, and the three preceding it very short and 
equal in length; prothorax short and very diagonally ampliated 
laterally from the anterior to the median part, somewhat deeply and 
closely punctured, each puncture bearing a hair; elytra of the 
normal shape but without any traces of costule, deeply punctured, 
each puncture divided by a smooth space equal to their diameter and 
each bearing a hair. 
Female unknown. This species is closely allied to HL. sierra leonis, 
Brsk., the type of which is a female, but the prothorax slopes more 
laterally from the anterior angle to the median part. 
Length 10 mm.; width 53 mm. 
Hab. Southern Rhodesia (Sebakwe).
