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 striae being smooth and blackish. 

 The type form of Carabus buquetii is the commonest Chilian 

 Caralus, but, strange to say, is not mentioned in Gray's work. It 

 is found everywhere in Southern Chili. The var. elegantissimus 

 is probably its most southern form, and was taken near Tres Montes 

 (46° S.)

Carabus moch*, 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. 1.1—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 elon- 

 gate-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. 



Var. 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 my species does not occur on the mainland.

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.
