tures, teeth long and sharp ; antennae black ; prothorax very convex, 

 carinate laterally for a short distance from the anterior angle which 

 is sharp, and serrulate from there to the posterior angle, basal 

 margin quite smooth and rounded, disk impunctate ; elytra ampli- 

 ated diagonally from the humeral angle to one-sixth of the length, 

 and attenuated from there towards the apex, base with a series of 

 ill- defined punctures or rather round impressions, one above each 

 stria, striation extremely fine, intervals nearly smooth and with 

 a very faint trace of a double series of very fine punctures, suture 

 gibbose past the middle, outer margin bi-carinate, the two carinae 

 diverging much near the base, suture gibbose past the middle ; pygi- 

 dium opaque, impunctate ; legs and pectus clothed with moderately 

 long black hairs ; anterior tibiae quadri-dentate outwardly, but with 

 the basal tooth shorter than the one following, but equally sharp, 

 denticulate from base to apex on the outer side, inner part closely 

 serrate and slightly mucronate at apex ; metasternum broadly but 

 not deeply grooved in the centre, and with a fine line in the 

 middle reaching from the apex to a round, shallow, basal im- 

 pression. 



Owing to the lateral ampliation of the elytra the facies is not 

 unlike that of Sceliages. 



Length 17-18 mm. ; width 12-12f mm.

Head and prothorax quite similar to those of *S'. con vex us; the 

 .antennae are yellow, except the three basal joints, which are brown, 

 but I have seen examples from Lydenburg and Pretoria in the 

 Transvaal in which the club is black ; the elytra have the same 

 sculpture, but they are more parallel, and therefore do not bulge 

 beneath the shoulder, and the two supra-marginal carinae are hardly 

 divergent at base ; the metasternum is not grooved, but has a longi- 

 tudinal fine line reaching from apex to base, and no posterior 

 impression. 



Length 18-23 mm. ; width 11-15 mm. 



Very closely allied to S. convexiis ; its distinctive character lies in 

 the more parallel shape of the elytra.
