This is a well-marked group of about eleven species, in which the 

 males are mostly of a nearly uniform, more or less shining black 

 or cinereous, and the females generally brown and variegated. The 

 genus is most highly developed in the pampas-districts of the South, 

 but one or two smaller species range up to the Orinoco.
