line, and a smooth, somewhat shining area on each side of it ; elytra 

 plane, but with the suture raised past the middle, slightly attenuate 

 towards the apex, indistinctly striate ; the intervals are sub-tecti- 

 form ; the sharp edge is shining and has a very indistinct series of 

 not closely set punctures ; outer margin bi-carinate, inner margin 

 very sharp and much raised from behind the shoulder to the middle, 

 suture shining ; legs slender, ciliate with long black hairs ; pectus 

 densely pilose ; metasternum closely punctulate, narrowed, not 

 deeply grooved, and ending behind in a narrow elongate impression 

 not much broader than the groove itself ; anterior tibiae with four 

 long, sharp outer teeth, and serrate from the base to the digitation, 

 while the space between the teeth is distinctly serrulate ; inner part 

 closely and finely serrulate ; pygidium with a few^ scattered 

 punctures. 



In one example from Wynberg, in the neighbourhood of Cape 

 Town, the lateral, basal smooth patch is closely punctate, and the 

 intervals of the elytra are more tectiform than in the examples from 

 Damaraland. 



Length 14-18 mm. 



This species is intermediate between >S'. i)roximus and >S'. sitri. 

 The shape of the thorax and legs is similar to that of the former, but 

 the sculpture of the prothorax is very different, and the elytra are 

 more parallel.

SCAEAB^EUS ALIENUS, U. SpeC. 



Black, head a.nd prothorax opaque, elytra nearly opaque, but with 

 the suture slightly shining ; head with a very distinct conical 

 tubercle in the centre, and covered with elongate, closely set 

 punctures, teeth sharp, but not as long, nor as acute as in the three 

 preceding species, lateral lobe ampliate laterally ; prothorax not 

 much convex, serrulate laterally, and fringed with sub-rufeseent long 

 hairs, anterior angle not very angular, basal margin with a series of 

 small, closely set punctures, disk very closely granulose laterally 

 and in the median part, the posterior part of which, however, is partly 

 closely punctulate and the supra-basal part impunctate except 

 above the scutellum, there is a distinct, median, longitudinal, smooth 

 line reaching from apex to base ; elytra sub-parallel, nearly plane 

 but with the suture slightly gibbose at about the middle, narrowly 

 but distinctly striate, the striae with a very slender double line, 

 intervals covered with an extremely fine aciculation, and having a 

 few slightly shining, extremely small, scattered granules, and a
