As far as we know, there are three geographical races of C. pareola to 

 be distiugnished.

In addition to these, we possess two males and a female, collected by 

 Prof. iSteere near JIarca da Legua, and at Margnary, in the district of Para. 



The adnlt males fully bear out the characters indicated by Mr. Bangs. All 

 have the under tail-coverts white, only the sides of the abdomen being ])ale grey ; 

 the black area on the back is restricted to a rather narrow transverse bund. 



Four d d ad. collected by Natterer near Borba (ou the lower course of 

 the Ivio Madeira) belong also to this well-marked form.
