1. Oxorius stipes, n. sp. Niger, sat uitldus, capite 

 coriaceo, subopaco, clypeo antlce emarglnato, et in medio 

 prominulo ; thorace parce punctato, medio brevlter canali- 

 cidato; elytrls strlgulosis. Long. corp. 7 — 8i lin. 



Head Avlth the surface coriaceous, and sprinkled Avlth 

 distinct punctures ; the clypeus emarginate in front, so 

 that the anterior angles form blunt projections, but not at 

 all spinose, and also obtusely prominent in the middle ; 

 the temples, over and behind the eyes, Avith coarse distinct 

 ruga?, and some small rough elevations. Thorax much 

 broader than long ; the sides much narrowed behind and 

 distinctly sinuate in front of the hind angles, which are 

 distinct and nearly right angles, but a little obtuse; the 

 sides distinctly impressed in front of the hind angles; so as 

 to make the lateral margin appear strongly raised there ; 

 the surface entirely coriaceous, but more finely so than the 

 liead, and with distinct though sparing punctures, and 

 Avlth a short, fine channel along the middle. Elytra dis- 

 tinctly longer than thorax, entirely covered with shallow 

 irregular rug^ ; on the underside the pn-ominence of the 

 prosternum is very marked, the niesostcrnum distinctly 

 carinate in front of the coxfe. The hind body with very 

 few setie, the a])lcal segment coarsely strlgose, especially 

 at the sides, and Avith strongly marked tubercles. 



Para, Eira : elo-ht individuals. 



Obs. — This is the largest species of the genus yet 

 knoAvn ; the structure of the front of the head readily dis- 

 tinguishes it from O. ater.

 antennis pcdibusque piceis ; capite pernitldo, parce sat

Front of clypeus distinctly notched on each side, the 

 lateral angles only slightly more prominent than the 

 middle. Head very shining, and Avith the front part not 

 in the least coriaceous ; the surface sparingly sprinkled with
