-. Elytra punctato-striate, intervals transversely rugose.......................................................... 3

2. Pronotum elongate-ovatum; elytrae depressed, intervals larger, an elongated sub-basal yellow patch on the 5th interval, a small dot below it on the 4th, three adjoining one another in the median region on 5th, 6th and 7th intervals respectively, two in the posterior region on the 3rd and 4th, two more a little lower down on the 5th and 6th and a supra-apical one close to the suture; legs yellowish, knees and tarsi brownish ( Botswana, Namibia and South Africa)........................ peringueyi Kuntzen

-. Pronotum more transverse-ovatum; elytrae sub-convex, intervals narrower, three yellowish, arched transverse patches composed of elongated spots, the first in the basal region on the 3rd, 4th, 5th and 6th intervals respectively, the second middle stripe on the 2nd, 3rd, and 4th intervals, and the last from the 3rd to the 7th interval forming an arch, the last spot of which is somewhat separate and no longer elongated but round and a single standing small spot on the 7th interval close to the tip of the elytra; legs with femora, tibia tip and tarsi brown-blackish, tibia yellowish ( Kenya, Tanzania, Mozambique, Zimbabwe and South Africa).......................................................................................... tesselata Klug

3. Pronotum subrectangular or trapezoidal inverted; elytrae yellowish patches: one sub-basal, other sub-median, both on 6th interval, more or less rounded or in a small longitudinal line, and two joint small longitudinal sub-apicals, respectively on 5th and 6th intervals ( Fig. 1 b ) ( Angola).................................................................. schuelei sp. n.

-. Pronotum oblong-ovate or fusiform....................................................................... 4

4. Pronotum oblong-ovate; elytrae depressed, parallel, deeply and closely punctato-striate, intervals narrow, sub-convex, an elongated longitudinal pale-yellow patch slightly notched in the middle on both sides situated in the first half near the lateral margin; another post-median, moderately large, transverse, and uneven one of the same color (South Africa R.)..................................................................................................... gracilis Boheman

-. Pronotum fusiform; elytrae a little convex, sub-parallel, deeply and broadly punctato-striate, intervals very narrow, convex; four round, rather indistinct, yellowish patches: a sub-basal median and a post-median one in a longitudinal line, a nearly juxtasutural round dot close to the post-median patch a little lower down ( Mozambique, Zimbabwe).......... egregia Peringuey
