latter is plainly incised laterally and narrowed thence to the anterior 

 angles which are sharp but not projecting in the male, the only sex 

 I know, and the anterior, reflexed margin is slightly bi-sinuate, there- 

 is a transverse impressed line in the anterior part reaching from one 

 end of the lateral incision to the other, but neither clypeal keel nor 

 clypeal suture ; the 4- jointed antennal club is longer than the 

 pedicel the two ultimate joints of which are very small and com- 

 pressed, and the club, the four joints of which are of almost equal 

 length, is flavescent ; prothorax deeply punctate, the punctures 

 round, equi-distant, and separated by a smooth interval nearly equal 

 in width to their own diameter ; elytra very coarsely punctured with 

 the intervals strongly coriaceous, the two dorsal costules very faint- 

 Length 6^—7 mm. ; width 3J-3f mm. 

 Hab. Southern Ehodesia (Salisbury). 



Camenta (Empecamenta) matabelena, n. spec. 



Black, and covered like C. nigra with an erect flavescent pubes- 

 cence ; it is, however, more robust, and the shape of the clypeus is 

 different, being incised laterally and narrowed towards the anterior 

 part as in C. nigra, but the apical angles are very broadly rounded, 

 and the median part deeply and broadly notched and very plainly 

 reflexed in both sexes, the transverse clypeal keel is quite distinct,. 

 and the clypeal suture is indicated in the male by a fringe of hairs, 

 but is visible in the female, the pubescence is denser and longer, 

 especially on the head and prothorax ; the elytra are deeply punc- 

 tured, but not coriaceous ; the antennal club of the male is slightly 

 shorter than the pedicel, and therefore not as long as in C. nigra, 

 and the genital armature of the male is also different. 



Length 8-|-9 mm. ; width 4-J-- 4f mm.

Camenta (Empecamenta) zambesina, n. spec. 



Black, with the elytra light chestnut, clothed with a flavescent 

 pubescence, very long and villose on the head and prothorax ; 

 clypeus incised laterally with the angles of the incision very sharp, 

 narrowed and parallel thence to the anterior angle which is strongly 

 and sharply produced and reflexed, the anterior margin being thus 

 arcuately emarginate, the keel and clypeal suture have disappeared 

 in the male, the only sex I know, but the latter can be detected in 

 the shape of a slight transverse elevation ; the head and the posterior 

 part of the clypeus are closely punctured, the prothorax moderately 

 so, and the punctures on the elytra are equi-distant, deep but with
