256 Mr. Waterhouse on Carabideous Insects. 
Sp. 5. Cascellius eneo-niger.—New species. 
C. niger, supra indistincté eneo splendens; thorace perlongo 
(elytrorum dimidiam longitudine zquante) supra paululum con- 
vexo, anticé latiore, posticé angustato; sulco dorsali mediocri- 
ter impresso ; elytris elongato-ovatis, distincté striatis; tibiis 
femoribusque piceo-nigris ; tarsis palpisque e piceo rubris ; an- 
tennis, articulo basali e piceo rubro, articulis duobus vel tribus 
proximis, piceo lavatis, reliquis fusco-testaceis. 
Hab. apud Valdivia. 
This species is about the same size as the last, but has the thorax 
more elongated, the elytra more distinctly striated, and the strie, 
although deeper in some parts than others, are not interrupted: in 
C. nitidus but five striz are visible, whereas in the present insect 
there are six or seven distinct striz, and these extend almost to the 
apex of the elytra: on the sides of the elytra the striz are not com- 
pletely obliterated: the colouring, moreover, is different, being al- 
most destitute of any metallic hue. 
The head is elongated and narrower than the thorax, distinctly 
constricted, and has a puncture in the centre, a little behind the 
eyes; between the eyes are two shallow fovee; the labrum and 
mandibles are black; the palpi are pitchy red; the basal joint of 
the antenne is red, the two or three following joints somewhat 
pitchy, and the remaining joints brownish testaceous ; the thorax is 
decidedly longer than broad; broadest in front, attenuated and cy- 
lindrical behind ; its upper surface is moderately convex ; the dor- 
sal channel is tolerably distinct, and extends very nearly to the an- 
terior and posterior margins (in one specimen the dorsal channel is 
interrupted on the fore part of the thorax and forms a series of punc- 
tures); the anterior and posterior transverse impressions can scarcely 
be traced, and the outer margins beneath are somewhat pitchy. The 
elytra are of an elongate-ovate form, distinctly striated, and the 
strie, in parts, exhibit indistinct punctures ; those nearest the su- 
ture extend almost to the apex of the elytra; near the outer mar- 
gins of the elytra the striz are indistinct: the interspaces of the 
other striz are slightly convex ; the apical portions of the elytra are 
pitchy at the margin, and have each three, more or less distinct 
punctures, two of which are placed near each other, and the third, 
which is most remote from the tip of the elytron, is widely separated 
from the other two. The legs are black or pitchy black, and the 
tarsi are pitchy red; the body beneath is black; the upper surface 
of the insect is black, but has an indistinct eneous gloss. Length, 
5 lines; width, 17 line. 
The two specimens from which the foregoing description is drawn 
up, are one from Valdivia, and the other from Cape Tres Montes. 
Two other specimens in the collection from Hardy Peninsula, Tierra 
del Fuego, differ in having the antenne, palpi, and tarsi darker.
