lete, the sutural angles separately arcuate; pygidium small, not 
densely pilose; anterior tibia with two long teeth distinctly sepa- 
rated, and having a slender inner spur. 
Length 18-5 mm. 
Hab. Portuguese East Africa. 
This species is rather longer than C. rufiventris (C. capra, Arr.), 
but the thorax is shorter. The posterior part of the head is covered 
with erect sete, the clypeus being naked, shining, and very narrow. 
The antenne, like the elytra and the lower surface of the body, are 
of a bright reddish-testaceous colour, and the antennal club is long. 
The legs and claws are of the normal form.” 
I have not seen this species, which differs from C. rufiventris in 
the narrow, naked, shining clypeus, divided from the frontal part by 
a highly raised keel. This last character is also found in Synclitopa, 
Kolbe.

Mentum long, sub-parallel laterally, faintly separated by an 
impressed line from the ligular part which is very short and deeply 
and broadly sinuate at the apex, the cotyloid cavities of the labial 
palpi are juxta-lateral, but set on the outer face of the ligular part, 
the three joints are short, thick, the last one very swollen, turbinate, 
and sharp at tip; maxilla robust, triquetrous, the upper lobe is 
broad, hollow, with the upper margin serrate and with four distinct 
spine-like teeth in the inner part, inner lobe obliterated ; maxillary 
palpi long, joints robust, second ampliated at the tip, third conical, 
apical one as long as the other two together, cylindrical, slightly 
truncate at the tip; clypeus as long as the head, arcuate in front, 
triangular in the anterior vertical part, and slightly impressed in the 
middle at the apex, labrum obliterated, frontal part simple, without 
a clypeal suture; antennz 10-jointed, the seven ultimate joints are 
laminate and form a long, not curved, club, the third joint is nearly 
equal in length to the basal one, but more slender and somewhat 
broadly triangular in the inner side; prothorax moderately ampliated 
laterally in the middle, but very little in the posterior part the angles 
of which are rounded; scutellum ogival; elytra slightly ampliated 
laterally past the median part, deeply punctured and sub-costulate 
and covering nearly the whole of the propygidium ; pygidium very 
wide, convex, drawn forwards ; abdomen and pectus villose, but the 
latter not very densely pubescent; anterior tibiz bi-dentate out- 
wardly, posterior ones with an interrupted, stiffly ciliate, diagonal keel,
