tectate, porrect process lightly emarginate at apex, beginning at 

 the anterior part of the head and overhanging the base of the 

 clypeus which is carinate longitudinally in the centre, the sides are 

 highly carinate, the carina truncate at about the median part with 

 the apex of the truncate part sharp, the anterior margin is produced 

 into a high vertical wall truncate at apex and broadly scooped in a 

 V-shape in the centre, the clypeus is sparsely pubescent ; prothorax 

 moderately closely punctate on the sides but not in the centre ; 

 scutellum very sharp, and bearing a few aciculate punctures ; elytra 

 non-costate, and somewhat closely punctate all over, the punctures 

 are nearly round, and moderately deep ; pygidium strigillate ; under 

 side sparingly pubescent on the pectus, glabrous on the abdomen, 

 and the strigillate legs ; sternal process closely punctate. 



This species differs from the typical Stephanorrhina (guttata; 

 princeps, adelpha, &c.) in having concolorous elytra ; the shape of 

 the head of the male is also very different owing to the absence of 

 anterior clypeal vertical horns, and the presence of an horizontal 

 frontal lamina instead of an erect T-shaped cephalic horn. The 

 genital armature of the male differs slightly only from that of 

 S. guttata. Female unknown. 



Length 26 mm. ; width 1(H mm. 



Hab. Southern Ehodesia (Gazaland). 



Group HETEEOEEHINII. 



In this group the sexual differences, when they exist, are not so 

 strongly manifest as in the Ceratorrhinii ; the clypeus in the $ when 

 differing from that of the ? is sub-parallel, and the centre of the 

 anterior margin is produced into a bi- or tri-fid horn, occasionally 

 reflexed and laminate ; the sternal process is usually long, but also 

 occasionally aculeate only.

 Mentum hairy, very little ampliated laterally, hardly broader than 

 the ligular part which is broadly emarginate at apex ; maxillae 

 robust, inner lobe simple, upper one broad, laminate, concave 

 inwardly and truncate at apex ; head and clypeus simple in both 

 sexes, the latter sub-parallel, deeply emarginate in front, antennal 

 club as long as the pedicel; prothorax of the usual trapezoid form, 

 sinuate on each side of the base and arcuate above the scutellum 

 which is long, sharp, and grooved on each side ; elytra elongated,
