CFTONII D_F OF AFRICA.

alluded to by Mr. MacLeay, in his observations on C. mieans, and 
which (ante p. 6), I stated to be identical with C. mieans, knowing 
only the species so named and figured by modern French authors, 
Mr. MacLeay himself not having alluded to any difference between 
the figures of Drury and Guerin. 
Species III.— C. splendens, M‘L. Viiidi-nitens, thorace punctis duobus cseruleis, eJytris 
vix striatis Jin eft obliqua hiimerali cserulea ; clvpeo $ latcribus bispinosis cornu medio 
porrecto recurvo apice bifido. Long. corp. lin. 24. 
Mr. MacLeay adds, 44 It is a species which conies very close to 
C. mieans, and belongs to the same section.” 
The above is all the description given by Mr. MacLeay of this 
species, of which he gives no habitat; so that we are left in doubt 
whether it be a native of South Africa, or not. 
Species IV.— C. Derby ana. Melly’s MS. Plate 42. Viridis nitidissimus, clypeo porrecto 
elytrisque albido-marginatis, capite nigro, cornubus duobus elevatis inter oculos, 
cornuque antico subrecurvo ; apice obtriangulari, £ clypci margine antico sub 3-sinuato.

The general colour of this splendid insect is a shining green with 
a bluish tinge. The head of the male above is black, except at the 
hinder part, which is green, and a large patch on each side of the 
central carina, covered with whitish velvety tomentosity. The 
front margin of the clypeus is nearly square, there being behind 
each of the anterior lateral angles an acute prominence, whence the 
head is gradually narrowed to the base of the antennm. The sides 
of the head are not elevated, but there are two horns elevated and 
obtuse between the eyes, standing out obliquely. (In C. cavifrons 
these horns are not distinct, but are confluent with the sides of 
the head, forming a very deep excavation on each side of the central 
carina). Along the middle of the head runs an elevated carina 
extending to the extremity of the central horn of the clypeus, which 
is rather recurved, with the sides angularly dilated. The under¬ 
side of the head, together with the trophi and antenme, are also 
black. The disk of the prothorax is very finely punctured. The 
sides with a very slight margin, and with a rather broad lateral 
band (gradually narrowed towards the hind angles) covered with 
whitish tomentosity. The elytra are similar in colour to the pro- 
thorax but rather more distinctly punctured, the punctures occa¬ 
sionally forming longitudinal lines. At each shoulder and subapical 
tubercle is a black patch; the tomentose marginal band ascends to 
a considerable distance along the suture, breaking into small spots. 
The fore tibiae have several (seven or eight) teeth along their inner
