460 Mr. CuRTis's Descriptions of 



shining ribs on each, including the sutural one, which are irregularly interrupted, being 

 continuous at the base, but granulated at the apex ; beyond the 7th, which forms a 

 lateral keel, is the inflected margin, on which are 2 rows of little shining black studs, 

 at remote distances : legs of the usual length and stoutness, shining and punctured : 

 anterior tibiae with the outer edge slightly crenated, the others scabrose : underside 

 rather strongly and thickly punctured, especially the apex of the abdomen, the base and 

 pectus somewhat striated. 

 Obs. — The punctures are filled with a dirty ochreous pubescence, apparently with a short 

 shining yellowish bristle in the centre of each, and this is most evident on the under- 

 side of the thorax and on the legs. 



Specimens of this very distinct species were found at Port Famine and Con- 

 ception. It makes an approach to S. tristis of Gu6rin, but all the angles of 

 the thorax are pointed in that species ; the antennae are also longer, the under- 

 side of the body is very finely punctured, the legs are small, rugose, &c. Vide

This is allied to the foregoing: a single specimen was presented to me by 

 Lieut. Graves, who took it in November at Maldonado.

 This figure is too black and too narrow for my specimens, which were found in 

 moist places in houses in Lima, but they well accord with Solier's description.

This and the preceding are introduced on account of their affinities and lo- 

 calities ; they were both transmitted to me by the late Mr. A. Mathews.
