 basi et tibiis posticis dimidio basali albo-testaceis ; thorace breviter

Tehuantepec, Mexico {coll. H. W. Bates). 



Closely allied to 0. nignclavis^ but destitute of brush on 

 the hind femora. Head coarsely punctured, black. The an- 

 tennte are tawny, moderately short, thickened towards the 

 tips, serrate from the sixth joint. The elytra reach nearly to the 

 middle of the third segment, and are much narrowed but not 

 subuliform, being little dehiscent at the suture and truncated 

 at the tip ; they are unicolorous pale tawny brown, with the 

 exception of a narrow blackish line along the anterior part of 

 the suture and of the lateral margins. The underside of the 

 body is closely punctured ; it is black, becoming castaneous on 

 the abdomen, the two basal segments of which have a broad 

 pale testaceous belt. The hind legs are moderately elongated, 

 and the femora somewhat strongly clavate. The metasternum 

 is voluminous, and the abdomen very elongate and slender 

 towards the base.

Deceptively similar to 0. albicans, Klug (Entom. Bras, 

 t. xliv. f. 5) ; colours the same, except a broad, triangular, 

 black spot in the scutellar region. The silvery pile of the 

 thorax, however, is concentrated in rounded spots, of which 

 there are four (in quadrangle) on the disk, and others more 

 irregular on the flanks ; and there are slight difierences in the 

 distribution of colours on the antenna? and legs. The white 

 ring of the antenna? in 0. albicans embraces joints seventh to
