from the apex and the median part there is a short, transverse, very 

 highly raised carina distinctly bi-tuberculate at tip, in the male, less 

 so in the female, basal angle of clypeus slightly raised ; prothorax 

 sinuate in front, and with the median apical part not recurved, it is 

 retuse in front for about half the length, has three deep excava- 

 tions, the median of which is the deepest, and also on each side of 

 the upper part two broad, triangular, sharp teeth, and the space 

 between these two teeth is deeply incised and continued as a deep, 

 median sulcus reaching the basal margin, the excavations are irregu- 

 larly punctate, the sides are more densely punctate, but the posterior 

 dorsal part has only a few punctures near the declivous part, and the 

 basal one is smooth and nearly impunctate ; scutellum very closely 

 and very finely aciculate ; elytra deeply punctato-striate, eighth 

 stria obliterated in the anterior part for about one-quarter of the 

 length ; under side and legs densely pubescent ; anterior tibiae six- 

 dentate. 



Both sexes similar. 



Length 14-22 mm. ; width 8-j— 10 mm. 



Hah. Cape Colony (East London), ? Ovampoland. 



I thought at first that the large example from East London might 

 prove to be identical with B. coryplicEus, Fab., but the figure of the 

 latter, as given by Westwood (Trans. Linn. Soc, vol. xxi., 1842, p. 19) 

 shows that it is quite a different insect, and one which I think is 

 erroneously alleged to be from the Cape. 



BOLBOCEEAS INDUBIUM, n. speC, 



Plate XXXVI., fig. 20. 



Female : Very similar to B. spurius ; it differs, however, in liaving 

 the cephalic carina situated nearly in the median part in a line with 

 the basal angles of the clypeus, the angles of the carina are also less 

 sharp, and the transverse carina is longer ; the tri-impressed excava- 

 tion of the anterior part of the prothorax is less deep, less sloping, 

 the median incision is less pronounced owing to the two tubercles 

 being less prominent, and the posterior median part of the disk is 

 distinctly more closely punctulate ; the disposition of the striae of the 

 elytra is similar. 



Male unknown. 



Length 14 mm. ; width 9 mm. 



Hah. Southern Ehodesia (Salisbury).
