Descriptive Catalogue of the Coleoptera of South Africa. 223 
Basal lunule coalescing with the anterior band which is broadly 
united also with the posterior along the suture, and narrowly 
along the outer margin, or with the basal dorsal patch and the 
two bands free but dentate and coalescing along the margin 
(pi. xxiv. , figs. 109, 110) africana. 
Basal patch slanting towards the suture, not connected with the 
anterior band which is broadly scooped in the fore border, the 
hind one being strongly tri-dentate, posterior band also scooped in 
front, the hind border produced in the centre in a rounded lobe 
beyond the edge of the band (pi. xxiv., fig. Ill) insolita. 
Basal patch round, not coalescing with the anterior band, both 
edges of which are sinuate, posterior band slightly broader than 
the anterior with the fore border deeply scooped in the centre, 
posterior border bi-incised (pi. xxiv., fig. 112) qnaclriguttata. 
Basal patch sub-ovate, anterior and posterior bands so broadly 
interrupted in the centre as to resemble four yellow patches 
(pi. xxiv., fig. 113) var. minuta. 
All the yellow patches reduced to a mere dot (pi. xxiv., fig. 114) . . var. namaqua. 
Elytra each with a basal dorsal and a lateral patch or spot, two 
sinuate transverse bands and an apical patch. 
A3. Antennae yellow, with the two basal joints black. 
Basal dorsal and lateral patches broad, rounded, the two bands 
broad, hind margin of the anterior, and both edges of the post 
median plainly bi-sinuate, apical patch ovate, red, the other 
patches and bands yellow (pi. xxiv., fig. 115) adamantina. 
A4. Antennae black. 
Basal dorsal patch comma-shape or sub-quadrate, the two trans- 
verse bands strongly zigzagged, posterior band slanting, sinuate 
dentate, occasionally united with the apical patch by a narrow 
spur (pi. xxiv., figs. 116, 117) histrio.

Black, clothed with a dense flavescent silky pubescence; the five basal 
antennal joints are black, the other five rufescent flavous ; the bands and 
patches on the elytra are moderately pale yellow ; head and prothorax 
covered with very closely set, well-nigh contiguous, slightly rugose punc- 
tures, frontal part with a central line and smooth patch ; elytra parallel, 
the black background and also the patches and bands covered with deep, 
sub-contiguous, slightly uneven punctures the intervals of which are too 
regularly raised to give the elytra the appearance of being shagreened, on
