palpi and antennae rufous brown, the club slightly flavescent ; pro- 

 thorax moderately convex, distinctly serrate along the outer margins, 

 and also along the l^asal one except in the central part which is 

 deeply and closely punctured, the disk is closely and finely granulose 

 laterally and closely punctured in the central part, with the punc- 

 tures more distant towards the basal part ; elytra very nearly as 

 bi'oad at base behind the shoulders as the prothorax at its widest 

 part, not ampliated laterally, and very little attenuated towards the 

 apex, sutural part very little gibbose at middle ; they are finely striate 

 with the intervals plane and have each a double series of small, 

 hardly discernible punctures ; pygidium faintly aciculate ; anterior 

 tibige with four long and sharp outer teeth, the part of the tibite 

 before the digitation is serrate, and the space between the digits 

 serrulate, but the inner part is not ; metasternum with a broad but 

 shallow groove between the intermediate coxae, and connected by 

 a fine line with a basal, shallow, quadrate impression. 



Length 23-29 mm. ; width 14-17 mm. 



Hab. Cape Colony (Bushmanland, Kakamas, Calvinia), Damara- 

 land (Otjimbingue, Swakop Eiver). 



The general facies of this species is very much like that of small 

 examples of S. rostratus and S. modcatus, but it is easily distinguished 

 by the absence of the dentiform process of the mentum, as well as 

 by the non-serrate inner part of the anterior tibiaB.

Black, equally shining on the upper side ; head covered with a 

 fine granulation between the eyes, central part slightly aculeate 

 occasionally in the 3' > clypeus covered with very elongated punc- 

 tures becoming striolate on the edges, basal lateral lobe granular, 

 anterior teeth long, sharp ; prothorax somewhat short, convex, not 

 much l)roader at its widest part than the elytra immediately behind 

 the shoulder, closely and finely serrate laterally with the serration 

 recurved, basal margin almost serrulate and with a median supra- 

 basal transverse line, disk finely and closely granulose, with the 

 granules less closely set near the base, in the centre is a narrow, 

 smooth, longitudinal, lineiform space reaching from the base to a 

 little beyond the median part ; elytra moderately plane, but with the 

 sutural part distinctly gibbose past the middle, a little ampliate from 

 beyond the shoulder to about one-quarter of the length, wliere it is 

 wider than the prothorax at its widest point, extremely finely acicu-
