Black, moderately shining on the upper part, slightly iridescent 

 underneath ; palpi and tarsi reddish brown, the three basal joints of 

 the antennae brownish ; head smooth, with the two impressions 

 between the eyes, but none on the vertex ; prothorax of the same 

 shape as S. validus on the upper part, but with the outer sides less 

 attenuated in front and thus more elongato-quadrate ; elytra as 

 broad as the prothorax at the base, nearly straight for two- thirds of 

 the length and then very slightly ampliated, a little convex in the 

 posterior part, punctato-striate, with the intervals convex, smooth, 

 the third, fifth, and seventh wider than the others, more raised and 

 united at the apex by a sort of ridge. Length 17 mm. ; width 

 7 mm.

Ligula broad, truncate at the apex with the margin sloping 

 slightly from the median part to the outer angle, and with two long 

 setae placed nearer to the median than to the outer part, disconnected 

 at about two-thirds of the length from the paraglossae, which are 

 slender, linear, and project a little beyond the ligula; mentum deeply 

 excavate, with a triangular tooth slightly rounded at the tip, and half 

 as long as the inner lobes, which are not much diverging and acute at 

 the tip; mandibles moderately long, arcuated, bent in at the tip; 

 palpi slender, the penultimate joints of the labial and maxillary palpi 

 nearly of equal size, but sometimes shorter (O.imlpalis, 0. angolensis), 

 the last one elongated and briefly truncate at the tip ; labrum sub- 

 transverse, plane, very slightly emarginate in front, and with four 

 setigerous punctures, the two median ones smaller than the others 

 and set close to each other ; head subquadrate, with a puncture on 

 each side of the basal sutural line of the epistoma, and with only one 

 seta over the back part of the eye ; antennae slender, reaching the 

 base of the prothorax, pubescent with the exception of the three basal 

 ones, which are glabrous ; prosternum with either a more or less 

 blunt conical process projecting between the coxae (type 0. palpalis), 

 and developed sometimes in a long, sharp spine (type 0. angolensis) ; 

 legs moderately long, anterior tibiae dilated apically, joints of the 

 tarsi narrow, elongated, subcorneal, the three basal ones of the 

 anterior pair in the male spongy underneath, dilated, the first one 

 narrowed at the base, the second one not broader than the first but
