" Deep black, not glossy. Antenna; scarcely as long as the thorax, 

 eleven-jointed, fuscous ; first two joints black. In the male the second 

 joint is very large, obhite-globose ; the interioi- joints of the flagellura 

 subglobose, beset with a few long hairs, the exterior joints much more 

 sleiuler, so that the antenna; might be tiescribed as moniliforni-seta- 

 ceous. In the female the joints of the flagellum arc subovate-globose, 

 but faintly pubescent, of nearly equal thickness (moniliform-linear).
