48 Mr. W. W. Saunders's Characters 



quadrate, transverse, rather broader posteriorly, the lateral mar- 

 gins smooth and somewhat rounded; the posterior margin straight 

 and the posterior angles bevelled off; the upper surface convex, 

 very finely granulated, shining. Scutellum minute, triangular. 

 Elytra about as broad as the thorax, ovate truncate, with the 

 lateral margins slightly reflexed, and the upper surface convex and 

 very shining. Legs robust, having the anterior tibiae broad and 

 flattened, with six well-defined teeth on the outer margin, and the 

 upper and under surfaces striato-punctate. The middle and pos- 

 terior tibiae sub-cylindrical, striato-punctate, with only one apical 

 tooth. Tarsi rather long and slender. Underside of body shining 

 black. 



Length, without mandibles, 1-^^^ inch. 



The elytra of this species are remarkably smooth and shining, 

 a character which at once catches the eye. Ev^ry specimen sent 

 home had the mandibles wanting, apparently pulled out from their 

 sockets. Mr, Fortune could give me no account of the cause of 

 this deficiency. The 0. glabratus of De Hahn is very closely 

 allied to this species.

 nate, and tlie posterior nearly straight, curving forwards near the
