Long. 12 mm. 
The yellow markings are placed on the prothorax, scuteL 
lum and post-scutellum (in the female there is a large 
yellow spot on the second ventral segment of the hind 
body); they are much less conspicuous (judgingby my 
specimens) in the male than in the female, but are pro- 
bably subject to variation in both sexes. The head is 
shining and very distinctly punctured, the punctures 
being rather crowded behind the base of the antennse 
and becoming gradually more sparing backwards; 
the mesothorax is shining and is distinctly and evenly 
punctured; the punctuation of the metathorax is 
rather coarse. The hind body is quite shining, but 
its brightness is hidden by close short whitish pubes- 
cence. In the male the apical half of the penultimate 
and the whole of the apical segment are rather densely 
covered with rather long golden red pubescence, 
which is still more conspicuous on the whole of the 
penultimate segment in the female, — -in this sex the 
elongate apical segment also having a dense fringe 
of long golden red hairs. In both sexes the clypeus, 
front of the head, and front tibiae are set with long 
golden red hairs. In the male the tooth on the sixth 
joint of the antennae is only moderately developed, 
and the ventral segments resemble those of C. stygius, 
Kirby. 
This beautiful species is allied to G. stygius, Kii*by, which 
it resembles in having the eyes widely separated^ 
and the space between them but little concave. The 
eyes are excessively finely facetted, and the hind 
body is shaped as in C. stygius, &c.
