This is a very common species. I have large series from 

 Guatemala, Chiriqui, Guiana, Trinidad, Tobago, Brazil, and 

 Colombia, which varies in colouration, but otherwise are quite 

 the same ; but I have some others which varies so much in the 

 colouration of the tail that I think a description is necessary.
