256 Mr. Waterhouse on Carabideous Insects. 



Sp. 5. Cascellius aneo-niger. — New species. 



C. niger, supra indistincte aeneo splendens ; thorace perlongo 

 (elytrorum dimidiam longitudine aequante) supra paululum con- 

 vexo, antice latiore, postice angustato ; sulco dorsali mediocri- 

 ter impresso ; elytris elongato-ovatis, distincte 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 striae, 

 although deeper in some parts than others, are not interrupted : in 

 C. nitidus but five striae are visible, whereas in the present insect 

 there are six or seven distinct striae, and these extend almost to the 

 apex of the elytra : on the sides of the elytra the striae 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 foveae ; the labrum and 

 mandibles are black ; the palpi are pitchy red ; the basal joint of 

 the antennae 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 

 striae, 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 striae are indistinct : the interspaces of the 

 other striae 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 aeneous gloss. Length, 

 5 lines ; width, lj 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 antennae, palpi, and tarsi darker.
