Descriptive Catalogue of the ColeoiJtera of South Africa. 203 
patches and bands orange-red ; pubescence black, erect ; head and pro- 
thorax deeply punctate, the punctures uneven and very closely set ; elytra 
with the black background very closely aciculate, the spots and bands 
with irregularly scattered punctures ; elytra elongated, each with an 
elongate ovate basal dorsal patch, and a smaller lateral one, the anterior 
band is somewhat narrow with the anterior margin straight, and the 
posterior deeply bi-sinuate, the second band is slanting from the suture 
to the outer margin, and expanding towards the sutural part is connected 
along it with another slanting supra-apical band reaching the outer 
margin, the anterior edge of the second band is broadly scooped laterally, 
the posterior edge is bi-dentate ; both edges of the supra-apical band are 
nearly straight. 
Length 15 mm. ; width 6 mm.

Monogr., p. 466, pi. v., fig. 41. 
Black, clothed with a short, black pubescence, antennae entirely black, 
the intermediate joints somewhat conical but not sharply acuminate 
inwardly, third joint one-third or more longer than the fourth ; head and 
prothorax covered with nearly contiguous, somewhat deep punctures, the 
prothorax is well attenuated into a neck, and the median line is very 
plain ; elytra with the black background covered with sub-contiguous 
deep punctures all very briefly setiferous, but very sparsely scattered on 
the pale yellow spots and bands ; the base has a broad orange-red border, 
below this are three patches of which the two dorsal ones are ovate, the 
lateral extends along the margin ; the ante-median band is very narrow, 
strongly zigzagged owing to the deep scooping of both edges; the posterior 
one consists of a transverse patch sending a narrow spur connected with 
an elongated supra-apical patch which is connected in the same manner 
with the other portion of the posterior band which abuts on the outer 
margin. 
This very distinct South African species was captured by Professor 
H. W. W. Pearson, in German South-West Africa, feeding on the 
inflorescences of that extraordinary plant, Welvitschia mirabilis. It is 
also found on the Nara melon Acanthosycios horrida. 
Length 17 mm. ; width 5|- mm.
