19. Odontocera aurocincta, n. sp. 



0. valde elongata, nigra ; antennis, tibiis et tarsis fulvis ; femoribus 

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

 cylindrico-ovato, grosse punctato, tomento aureo marginato ; elytris

 vitreis. Long. 7 lin. 5 . 



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



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

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

 tennee 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 

 subulifonn, being little dehiscent at the suture and truncated 

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

 exception of a nan-ow blackish line along the anterior part of 

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

 body is closely punctm-ed ; 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 metastemum 

 is voluminous, and the abdomen veiy elongate and slender 

 towards the base.

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

 t. xliv. f. 5) ; colom-s 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 fom- (in quadrangle) on the disk, and others more 

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

 distribution of colom-s on the antennre and legs. The white 

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