Ohs. — This species is closely allied to O. nitens, but is 

 rather smaller and distinctly iiiore slender; the clvpeus is 

 not prominent in the middle, and the; antennal tubercles 

 are more distinct ; it is possible that the paler colour may 

 be only the result of the immaturity of the individual de- 

 scribed.

 raceque crebre, fortiter punctatis, illo clypeo antice emar-

Cl>^eus emarginate in front, the angles not produced. 

 Head rather coarsely and moderately closely pimctui-ed, 

 Avith a smooth space in front of the finely-punctured 

 vertex ; black and shining, not coriaceous. Thorax about 

 as long as it is broad at the base, only a little narrowed 

 from the front to the base ; the hind angles distinctly 

 obtuse, but not far from right angles ; the surface shining 

 black, rather coarsely and not very sparingly punctured, 

 and Avitli traces of a short channel on the middle. Elytra 

 a little longer than the thorax, shining, -with a distinct 

 l)ut neither dense nor deep sculpture, consisting of indefi- 

 nite rugffi, and sparing, ill-defined, elongate punctures. 

 Hind body black; above sjiaringlv sprinkled with obsolete 

 punctures, beneath with the 7th segment in the middle 

 coarsely punctured, and bearing a fine elongate pubes- 

 cence, the punctures at the sides more sparing, but coarse, 

 and ])assing into shallow ruga^ ; Gth segment coarsely 

 punctured about the middle, and the preceding segments 

 also with some coarse punctures about the middle.

Ohs. — This s]K>cics at first sight exactly reseml)les 

 O. niteiis, but the clvpeus is not jirominent in the middle; 

 the head and thorax are more distinctly punctured, and 

 the punctuation of the hind body is different.
