three-fourths of the outer orbits on the lower third, base of pronotum, 
mesonotum, the metanotal area except the outer basal half narrowly, 
a smaller triangular mark above it, the narrowed end above, the pro- 
pleurae except at the apex above, the mesopleurae except the tubercles 
and an oval mark immediately below them ; the mesosternum, meta- 
pleurae, a large irregular spot in the centre of the fourth and fifth segments ; 
the apex of the pygidium, a line, rounded at the base, on the apical two- 
thirds of the fourth ventral ; a large triangular one on the fifth and the 
greater part of the sixth, black ; the basal four dorsal segments are tinged 
with yellow; wings hyaline, distinctly tinged with fulvous; the costa, 
stigma, and nervures rufo-fulvous ; the first recurrent nervure is received 
shortly before the middle ; the apex of the wings, from the apical trans- 
verse nervures, fuscous-violaceous ; metanotal area at the base obliquely, 
at the apex transversely, striated. Male.

The clypeus projects roundly and obliquely on the lower three-fourths ; 
the base is flat and is bordered above by a semicircular furrow ; it becomes 
narrowed towards the apex, which is transverse and depressed; the sides 
are densely covered with pale golden pile from the top of the face, which 
is sparsely, weakly punctured and tinged with yellow on the inner half; 
the head, except the oral region, is closely, strongly punctured ; the lower 
part of the outer orbits is more or less striated ; propleurae with a few 
longitudinal striae, the rest of the thorax closely, strongly punctured, 
the punctures on the pleurae running into reticulations ; abdomen sparsely 
punctured, the punctures becoming weaker towards the apex ; pygidium 
almost impunctate, the basal two-thirds becoming slightly narrowed, 
the apex more distinctly narrowed ; the incision in the hypopygium 
extends close to the middle ; it becomes slightly, gradually narrowed 
inwardly, the base being rounded. 
This species is nearly related to the Cape C. melanospila * Cam. ; they 
may be separated thus : — 
The black on the front extending behind the eyes ; the metathorax entirely black ; the 
metanotal area entirely, obliquely striated. Melanospila. 
The black on the front not extending to the end of the eyes ; the metanotum laterally 
red ; the metanotal area not entirely, obliquely striated. Jansei.

Black ; the clypeus, a broad line extending from shortly above the 
middle of the eyes to the mandibles, the antennal tubercle, basal half of 
mandibles, a spot near the middle of the antennal scape, a transverse 
oval mark on the sides of the apex of the pronotum, tegulae, post- 
scutellum, an irregular spot on the base of the second abdominal segment, 
a larger transverse one on the sides at the apex, the three forming a triangle^
