This series is very constant in coloration aside from a slight 

 variation in the depth of the ground color of the head. The Jujuy 

 individual, alone of the series, has the proximal portion of the external 

 face of the caudal femora more olive green than in the other specimens 

 and blending into the blackish disto-median band. There is no 

 tendency in the series to approach the Brazilian Z. tarsata (Serville) . 



The northern limit of the range of the present species is not defi- 

 nitely known, as most of the records are confused with tarsata, but to 

 the southward, where cruentata alone is found, its range is given by 

 Bruner as "central and northern Argentina." The above records 

 and that from Buenos Aires (Giglio-Tos) are the most southern 

 definitely known ones.

This species has been recorded from as far north as Caiza, Bolivian

 to Santiago del Estero (Stal) and Cordoba, Argentina (Bruner).
