ed^es of tlie alxlDminal seL;iiients ; plane, distinctly striate, the stviai 

 are punctulate, and tlic intervals nearly plane on the disk, ])ut 

 slightly convex laterally, and very linely aciculate, the lateral 

 tiavous band is very broad laterally, hut the apical one is narrow ; 

 pygidiuni punctulate, glabrous ; the underside and legs are nearly 

 glabrous ; the prosternum is produced into a broadly triangular pro- 

 cess, strongly carinate at tip between the coxic, and impinging far 

 on the apical part of the raetathorax, which has a deeply impressed 

 median line reaching from apex to base, is smooth in the middle and 

 very broadly but not deeply punctured laterally; legs and tibiic com- 

 pressed, first joint of posterior tarsi moderately dilated. 



Length 13-16 mm. 



Hab. Transvaal (Potchefstroom, Lydenburg), Southern Rhodesia 

 (Victoria Falls). Occurs also in German East Africa and Southern

Black, smooth, shining, elytra slightly iridescent ; head broader 

 than long, clypeus very slightly emarginate in front, gena3 not pro- 

 jecting beyond the line of the clypeus, suture of the gente carinate' 

 as far as the eyes, surface of the head without any carina or impres- 

 sion in either sex ; prothorax quite smooth and impunctate, plane, a 

 little attenuate and rounded laterally in the anterior part, but some- 

 what parallel laterally, and with the base nearly straight ; above ttie 

 median part of the base there is a very short, longitudinal impressed 

 line ; scutellum small ; elytra a little narrower at base than the pro- 

 thorax, sub-parallel but a little attenuate behind, not sinuate laterally 

 behind the humeral part, and covering the episterna, but not entirely 

 the edges of the abdominal segments ; they are plane but deeply 

 impressed behind the humeral callus, distinctly punctato-striate 

 with the intervals smooth and glabrous except at the apex where 

 there is a distinct fringe of greyish setae ; pygidium finely acicu- 

 late and opaque ; under side glabrous but for a few hairs on the 

 sides of the prothorax and on the anterior femora ; the prosternum 

 is produced into a broad triangular process very sharp between the 

 coxEe but with the basal part not overlapping the metathorax which 

 is smooth in the centre, but closely sub-foveate laterally, and has a 

 very faint median longitudinal impressed line; posterior tarsi a little 

 dilated, basal one longer than the three following. 



Length 10-11 mm. ; width 6 mm.
