Species of Carabidae from South Africa. Al 
of head and prothorax is finely coriaceously plicate. In 
cham the plications are very faint, sub-obsolete, and, per 
contra, the subbasal depressions and fovez are deeper. The 
intervals of the elytra are in cham more carinate, the strize 
narrower, deeper, and distinctly punctate. There is a com- 
plete absence of metallism in all specimens of C. cham that 
have come under my observation. I have examples of this 
species from districts as wide apart as the neighbourhood of 
Durban and Frere, 7. e., 161 miles, and with a difference in 
altitude of 3500 feet, yet they show no variation from type. 
The altitude of Harding is approximately the same as that 
of Frere, but considerably more than 14 degrees to the 
southward. It must be confessed, however, that the modifi- 
cations of structure and sculpture are only slight, and 
further knowledge may prove later clarksoni to be only a 
local race or subspecies of Chaudoir’s insect. 
Specimens of C. clarksoni show considerable variation in 
the extent of metallic green underlying the bronze. Some 
appear to be nearly wholly green in strong lights and others 
under similar conditions show only faint traces of it. It is 
always more or less noticeable about the margins and in 
the interstices of the elytra. I submitted one or more 
examples to Dr. Péringuey, in the year 1899, who then 
pronounced it a new species and gave it the MSS. name 
barkeri, but no published description nor further mention 
of it has since reached me. 
All the examples so far known to me were collected by 
Mr. Clarkson on his farm near Harding, Alfred County, 
Natal, who informed me that he found them harbouring 
under dry cow-dung. 
Soutu-Arrican Cazzyirt With a CaLATHUS-LIKE FActizs. 
Of this very distinctive section of a huge genus Dr. 
Péringuey, in his ‘ Descriptive Catalogue,’ 1896, pp. 517-519, 
has described or referred to six species, five of which are 
represented in the Durban Museum Collection, namely, 
Chlenius dichrous, Wied.; C. piceus, Chd.; C. trapezicollis, 
Chd.; C. natalensis, Chd.; C. erythrocnemis, Chd.—leaving 
only C. ovodiordes, Chd., unaccounted for. 
C. cham, Chd., and C. clarksoni, mihi, described ahove, 
I have purposely omitted, as I consider they belong to a 
class apart. Péringuey also described a species under the 
designation aculeatus, but this he has since recognised is not 
Chlenius at all, but a Pterostichid of an, at present, undeter- 
mined genus.
