with a purple iridescence ; posterior wings clear hyaline, their 
apex fuscous. Abdomen closely and rather more finely 
punctured than the thorax, the first segment entirely covered 
with short white pubescence above; the rest of the segments 
with a thin line, broadening laterally, of white pubescence at 
their bases; the fourth and fifth segments with a deeply im- 
pressed transverse line before their posterior margins, beyond 
which the margins of the segments are smooth and shining ; 
the penultimate segment has a short conical tooth on each 
side, and the apical segment six rather longer spines or teeth, 
two laterally and four at the apex; beneath, the segments of 
the abdomen have a line of white pubescence at their basal 
margins, and the extreme apex a tuft of rather rigid white 
hairs, tinged fulvous. 
Somewhat resembles C. fuscipennis, Smith, in the colour 
of the wings, which, however, are much darker in the present 
species. It also differs entirely from Smith’s species in the 
form of the apical segment and in having the basal segment 
of the abdomen above covered with snow-white pubescence.

Eight males and three females. One pair taken 7n cop. 
One specimen (a male) differs considerably from the rest ; it 
may represent a distinct species. ‘The wings are a much 
darker brown, and only the basal segment and the base below 
and sides of the second segment of the abdomen are red, the 
remainder of the abdomen being black and shining. The 
form and sculpturing of the thorax, however, do not differ 
from those of swspictosa, and so I have provisionally identified 
it with that species. 
Smith described the male. The female has the head and 
abdomen black, the thorax red. The head is closely and not 
very finely punctured, and has a little silvery pubescence 
between the antenne. The thorax is coarsely punctured, 
compressed and slightly emarginate at the sides; the legs are 
black, with the calcaria and pubescence fulvous. The abdo-
