Black, very shining all over ; antenna) fuscous ; clypeus sharply 

 five-dentate, sci'obiculate, head with a sub-quadrate posterior patch 

 smooth in the centre and with a few lateral round punctures ; this 

 quadrate patch is produced triangularly in front ; prothorax convex 

 in the anterior part, where it is somewhat dehiscent, more than 

 twice as broad as long, having a few punctures somewdrat closely 

 set on the sides of the anterior part, but widely scattered on the 

 disk, and a little more numerous along the base than above it ; it is 

 strongly serrate laterally, the margin ending abi'uptly in a sharp 

 angle a little above the rounded part of the base ; elytra gradually 

 attenuate laterally from the rounded sub-humeral part to the apex, 

 which is narrower than the base l)y about one-fourth of the width ; 

 the sutural part is raised at about the median part ; it is very slightly 

 striate, the striiB being merely indicated except near the basal part 

 by sub-obliterated seriated punctures ; pygidium punctate ; metaster- 

 num sharply aculeate, and without any median groove or impression; 

 anterior tibiae very sharply quadri-dentate and very closely and 

 strongly serrate inwardly and outwardly ; the hind legs are as long 

 and as strongly sinuate as in S. intcrstitialis. 



Length 12-17 mm. ; wddth 8-11 mm. 



Hah. Southern Rhodesia (Victoria Falls), Mozambique (Inham- 

 bane), Transvaal (Lydenburg). 



The sub-mucronate posterior part of the lateral margin of the 

 prothorax is peculiar to this species. In the large examples (type) 

 the elytra are more distinctly attenuate laterally towards the apex. 



Scarahaus politifrons, Fairm., is the same species as S. ebenus, but 

 in my example from Shoa the punctures on the prothorax are a little 

 less deep laterally, and the median part of the disk is more im- 

 punctate ; but the punctuation varies also in the four examples of 

 -S'. ebenus which I have seen, and is denser in the small development.

Black, shining ; under side and legs fringed with rufous hairs ; 

 head granulose in the basal part and also on the lateral lobe, covered 

 with elongate punctures closely set and forming a sort of striation 

 near the edge of the clypeus the teeth of which are sharp and long ;
