certain light, and in a different light appearing almost of the 
colour of the derm. The front tibie too are peculiar, being 
scarcely dilated externally into a defined tooth even at, the apex, 
and above the apex having only a very minute sharp tooth about 
the middle. The example before me has no trace of a removable 
indumentum.

C. tridens, sp. nov. Elongata; postice angustata; supra glabra, 
subtus pilis pallidis vix aliter quam C. imperialis vestita ; 
nigra, labro prothoracis vitta utrinque laterali antice posti- 
ceque abbreviata et elytris flavis, his nigro-notatis, pictura 
antice tridenti postice cultro simili; capite subfortiter 
acervatim punctulato, longitudinaliter inter oculos antice 
carinato postice sulcato; prothorace quam longiori (et postice 
quam antice) circiter dimidio latiori, foveis sat numerosis 
impresso, canaliculato, sparsim subtiliter (angulos anticos 
versus, nec ad latera, magis crebre) punctulato, lateribus a 
basi ad apicem sinuatim convergentibus, angulis posticis 
acutis sat productis ; elytris apice singulatim subspinoso- 
acuminatis, levibus, puncturarum seriebus intra substantiam 
positis per superficiem conspicuis; prosterno antice et ad 
latera sat fortiter rugulose punctulato retrorsum gradatim 
fere levi; metasterno ad latera sparsim sat fortiter punctu- 
lato, in medio fere levi, abdomine ad latera sparsim sub- -

The pattern on the elytra at once distinguishes this species ; it 
consists of a single common black mark, which (in the example 
before me) touches base, apex, or lateral margin only at the base 
of the suture. This black mark, in the hindmost third part of 
the elytra, is shaped like a ploughshare, from the middle of 
which (on the suture), rises a mark resembling a handle ; on this 
handle, and occupying more than the front half of the elytra, 
rests the anterior portion of the black mark, which resembles a 
trident, with the three prongs directed forward, the lateral 
prongs nearly (and the middle one quite) reaching the base of the 
elytra. 
Compared with C. imperialis, Don., apart from colour and 
pattern, this species is, throughout, much more finely punctured. 
The prothorax is not more closely or coarsely punctured on the 
sides than on the disc; besides the round fovea at the base of 
the median line, there are two sharply defined foveze on either 
side, placed longitudinally, about half-way between the median
