Piceous red, with a faint metallic tinge ; somewhat depressed ; 

 head granulate, no clypeal carina, frontal one arcuate, basal one 

 sinuate, nearly as much raised as the frontal one, and slightly 

 tuberculate in the middle, gense not rounded, but not projecting at 

 tip ; prothorax attenuate laterally for one-third of the length, and 

 very little rounded from there towards the basal angle, marginate in 

 front and laterally, but not at base, not very convex, and covered with 

 somewhat closely set punctures changing into minute granules on 

 the two basal impressions which are shallow ; scutellum very small 

 but distinct ; elytra sub-parallel, slightly sinuate behind the shoulder, 

 humeral callus developed only on the seventh interval, narrowly 

 geminato-striate with the intervals plane and finely, but very 

 distinctly, punctured, the punctures very briefly setigerous ; pygidium 

 convex, very slightly granulose ; metasternum entirely granulose, 

 and faintly sulcate longitudinally. 



Male : Clypeus rounded and deeply emarginate at tip ; anterior 

 tibijB bluntly quadri-dentate outwardly with the teeth equi-distant, 

 straight internally for three-fourths of the length and emarginate at 

 a short distance from the base of the mucro which is very short, 

 blunt, and densely ciliate, underneath there is a very sharp carina 

 running from apex to base, and forming a triangular tooth at base ; 

 femora and intermediate tibiae simple, but the intermediate femora 

 are sometimes slightly crenulate beneath, posterior tibicie compressed 

 in a laminate remiform process rounded externally, sinuate in- 

 ternally and without any external teeth (fig. 9). 



Female : Clypeus aculeate, a little truncate at tip, and with the 

 margin recurved ; tubercle on the vertex a little more raised than in 

 the male ; intermediate femora serrulate underneath. 



The shape of the posterior tibiae of the male will easily lead to the 

 indentification of this species ; the female very much resembles that 

 of 0. ahynsinicus, and especially that of 0. invcrsldens, but the
