According to the author himself, this species must be very closely 
allied to C. fulva. I think that the Cape insect is not sufficiently 
distinct from the cosmopolitan and very variable C. fulva. Mot- 
schulsky says nothing about the antennz and the sexual character 
of the fifth ventral segment. If the structure of these organs 
is the same as in C. fulva, it will be easy to distinguish the present 
species from its congeners C. pubescens and C. capensis, because in 
the antenne of C. fulva all the joints are not elongate, the seventh 
and eighth are hardly as long as wide; besides the two first joints 
of the antennal club are not obconic and very attenuate towards the 
base, but proportionally shorter and rounded and dilated in the 
base itself. The fifth abdominal segment of C. fulva has not the 
large rounded fovea characteristic of both sexes of C. pubescens, but 
has instead a transverse impression rather distinct and deep in the 
male, and more or less obsolete in the female. Comparing the two 
species, Motschulsky says that C. tenwcorms is ‘hardly smaller 
than C. fulva, the median antennal joints are more slender, the 
pubescence on the elytra is less elongate and less closely set; all 
the intervals are narrower, and the lateral ones are somewhat 
raised.”

In this sub-genus are included the species with short, thin, decum- 
bent, and often scanty elytral pubescence; the fifth ventral segment 
has generally a single little fovea in the male, and sometimes also in 
the female.

A few examples of this common and cosmopolitan species taken 
together in the Cape Colony represent three types of colouration ; 
the normal one, 7.e., rufescent on the thorax and blackish on the 
elytra, and two others in which the whole body is either dark or 
uniformly pale testaceous. 
Body oblongo-ovate and convex; eyes contiguous with the front
