a, ovatulus, Per., Trans. S. Afric. Phil. Soc, 1888, p. 78. 



Head broadly denuded in the centre ; antennae and legs black ; 

 prothorax black, with a narrow median groove, and with a narrow 

 band of dark ferruginous hairs on the outer sides ; elytra elongato- 

 ovate, covered with a deep ferruginous or fulvous pubescence, with a 

 very narrow often hardly noticeable whitish outer margin, and a 

 broad sutural black band as broad as the denuded part of the 

 prothorax, but tapering slightly towards the apex.

 restricted to the Transvaal, but found together with the large ex- 

 amples. Length 10-15 mm. ; width 4-7 mm.

Covered with a pale yellow pubescence ; head broad, narrowly 

 denuded in the centre ; the two basal joints of antennae reddish ; 

 prothorax not much broader than the head, with a discoidal broad 

 black band on each side, thus dividing the background into a mode- 

 rately broad median yellow band and two marginal ones ; elytra 

 rounded in the anterior and posterior angles, but with the outer 

 sides somewhat parallel, and having a very broad black sutural band 

 and two very narrow ones on each side of the disk, thus leaving on 

 each side two alternate narrow yellow bands and a margin of the 

 same size and colour ; legs black. Length 14 mm. ; width 5-|- mm.

 with a very short pubescence, black or greyish black, faintly striate, 

 and with a narrow marginal band of white hair ; legs black. Length 

 16 mm. ; width 6 mm.
