Show 54 MR. E. C REED ON CHILIAN COLEOPTERA. [Jan. 6, anterior angles, whence the sides are gradually sinuate-angustate to the base, the hind angles being remarkably acute. In some examples the " chain striae " of the elytra are very strongly marked, the oblong raised intervals of these stria? being smooth and blackish. The type form of Carabus buquetii is the commonest Chilian Carabus, but, strange to say, is not mentioned in Gay's work. It is found everywhere in Southern Chili. The var. elegantusimus is probably its most southern form, and was taken near Tres Montes (46° S.) CARABUS GLORIOSUS, Gerst. /. c. p. 429, t. iv. f. 6. Carabus chilensis, var. /3, Solier, I. c. p. 126. Carabus carinulatus, Motsch. Bull. Mosc. 1865, iv. p. 284. Occasionally found in the province of Valdivia. CARABUS MOCH^E, n. sp. (Plate XIII. fig. 4.) C. glorioso (Gerst.) affinis, elongato-ellipticus, modice convexus,• supra subopacus, cuprescenti-niger ; elytris rubro-cupreis, sutura limboque laterali nigro-violaceis, interstitiis elevatis undique interruptis, alternis elevatioribus; corpore subtus cuprescenti-nigro. Long. 11-12 lin. The thorax in this species is always narrower than that of C. gloriosus, and rather more cordate in form, having its greatest width at a short distance from the anterior angles. The elytra are elongate- elliptical. All the depressed portions of their surface are opaque, without distinct striae; and the narrow raised interstices are interrupted by innumerable transverse impressions, which cause them to appear as rows of shining tubercles. The alternate interstices, however, are more continuous. Far. In some examples the elytra are dark green in colour, with the suture and a lateral border coppery. I discovered this fine species on the island of La Mocha, situated some twenty-three miles from the coast of Chili, in lat. 38° S. This island is of Tertiary formation, similar to the coast in front of it, and was evidently at one time connected with the mainland ; but I feel sure that m y species does not occur on the mainland. CARABUS VALDIVI^E. Carabus valdivia, Hope, Trans. Entom. Soc. ii. p. 128 • Gerst I. c. p. 431, t. iv. f. 7-13. Carabus chilensis, Sol. I.e. p. 126, t. ii. f. 1. Small examples of this species resemble very closely robust individuals of C. buquetii; but they may always be distinguished by the perfectly smooth undersurface of the thorax. This species is, after C. buquetii, the commonest Valdivian species. CARABUS CHILENSIS. Carabus chilensis, Esch. Zool. Atlas, ii. p. 9, t. viii. f. 7 • var. a Sol. I. c. p. 126. * |
