finely striate with the intervals plane and slightly aciculate, the 

 aciculation is more shining than the hackground ; the two supra- 

 marginal carinse are set very close to one another, and are hardly 

 diverging at the base ; pygidium aciculate ; anterior tibiae strongly 

 and sharply quadri-dentate outwardly, crenulate inwardly from under 

 the second outer tooth to the basal one, outer side sub-serrate from 

 the base to the digitation ; the surface is foveolate on the upper part, 

 and closely striate underneath ; metasternum not aculeate at apex 

 and grooved from apex to base. 



Length 27 mm. ; width 18 mm. Female unknown.

SCARAB^US RIXOSUS, U. speC. 



Black, moderatel}' shining ; head, thorax, and legs fringed with 

 fulvous hairs ; head granulate at base, centre, and sides, clypeus 

 striolate, teeth sharp, recurved, the two anterior ones not carinate 

 beneath, central part of the head with a very conspicuous, sharp, 

 triangular tubercle, mentum with a broad triangular, very con- 

 spicuous tooth-like process sharp at tip ; prothorax moderately 

 convex, serrate laterally, closely punctured along the l^asal margin, 

 ■closely and deeply aciculate, almost shagreened along the 

 anterior margin and on the sides, and with moderately closely set 

 granules replaced along the base and in the posterior median part 

 hy punctures ; elytra with very oblique shoulders, a little attenuate 

 from behind the humeral part towards the apex, slightly gibbose at 

 middle towards the suture, very finely striate with the intervals 

 plane, smooth, and having two series of very fine, shallow, yet 

 distinct punctures ; the two supra-marginal carinte are very sharp 

 and raised, and do not diverge much at base ; pygidium punctulate ; 

 the anterior tibiae have four very strong, long outer teeth, and are 

 strongly serrate from the digitation to the base, inner part carinate 

 but not serrate, upper part foveolate, under side striate ; upper edge 

 of femora serrate at apex ; metasternum not aculeate at tip, not 

 deeply grooved in the anterior part as far as the median coxae, 

 posterior part with a shallow impression. 



Length 29 mm. ; width 18 mm. 



Near S. rostratus ; differs mainly by the shape of the vertical 

 tooth in the mentum, which is shorter, broader, and not bifid at tip ; 

 the cephalic tubercle is also sharper and as long as in S. zam- 

 besianiis ; the elytra, however, are not so parallel nor so elongate as 

 in S. rostratus, and the sculpture of the prothorax is also different. 



Hab. Southern Rhodesia (Middle Limpopo).
