lete, the sutural angles separately arcuate; pygidium small, not 

 densely pilose ; anterior tibiae 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 G. rufiventris (G. capra, Arr.), 

 but the thorax is shorter. The posterior part of the head is covered 

 with erect setae, the clypeus being naked, shining, and very narrow. 

 The antennae, 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 ; maxillae 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 ; antennae 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 tibiae bi-dentate out- 

 wardly, posterior ones with an interrupted, stiffly ciliate, diagonal keel,
