raised dorsal carinae ; pygidium not deeply punctate, and having a 

 moderately wide transverse smooth area. 



Var. a. testaceous-red, head black, legs piceous. 



Length 9f mm. ; width 6 mm. 



Hab. In the neighbourhood of Lake N'Gami." 



I have seen the type only of this species. From my notes I find 

 that it is almost twice as large as Oocamenta ruftventris, and is there- 

 fore very short and stout, the clypeus is short, very deeply incised in 

 front in the anterior margin, slightly constricted laterally, the angles 

 of the stricture being dentate, and the transverse carinuleis a clypeal 

 one. I did not at the time look at the number of antennal joints, 

 but it is very doubtful if this species belongs to Gamenta. 



PEEICAMENTA, n. gen. 



This genus differs from C amenta merely in the number of antennal 

 joints, which is nine instead of ten. In the male, the only sex 

 known to me, the club is 5-jointed, the inner joint being only slightly 

 shorter than the one following, the fourth joint of the pedicel is 

 compressed and acuminate, and the third one moderately long ; the 

 shape of the clypeus, and also the general facies, is that of Camenta 

 innocua or G. nigrita. 



Pericamenta paupercula, n. spec. 



Dark chestnut-brown, with the head and prothorax fuscous, 

 antennae rufescent, legs piceous ; clypeus straight laterally, slightly 

 narrower at the apex than at the base, anterior angles moderately 

 rounded, anterior margin sinuate, the clypeal carina looks more like 

 a suture, being hardly raised; antennae 9-jointed in the male, the 

 club 5-jointed with the inner joint slightly shorter than the one 

 following, and the fourth joint of the pedicel short and compressed ; 

 the head and prothorax are covered with punctures of the same 

 size, the elongate elytra are somewhat deeply punctured with the 

 intervals slightly coriaceous, and the costules are quite visible. 



Length 10 mm. ; width 5 mm. 



Hob. Cape Colony (no exact locality). 



OOCAMENTA, n. gen. 



Buccal organs of Camenta, the number of antennal joints is, how- 

 ever, 10 in the male with a 6- or 7-jointed club the joints of which 

 are equal in length, and of nine in the female, in which the club is 

 4- jointed and the joints also equal in length ; the clypeus is not
