? al. 71^, caud. 641, culm. 12, tars. 20i mm. 



Habitat : Tucuman. 



Typus : in Mus. H. v. B. S Norco, Tucuman, 7th August, 

 J 904. [L. Dinelli leg. No. 3250.] 



Of this form I have seen three males and one female, all 

 collected by Mr. L. Dinelli at Norco, Tucuman. They differ 

 from a specimen collected by Mr. G. Garlepp near La Paz, 

 Bolivia (which should be true 0. leucophrys Lafr. et D'Orb.), 

 in having the rump conspicuously washed with rufous and 

 the middle back also slightly rufescent, while in the La Paz 

 bird the upper parts are of an uniform dark raw brown. In 

 the Tucuman birds the rufous-brown tips to the upper 

 wing-coverts are broader and of a brighter tint. The outer 

 margins of the tertiaries are also bright rufous instead of 

 whitish-fulvous, and much broader than in the La Paz 

 specimen.

This southern representative of U. polionota Sci. et Salv., 

 from Peru, is distinguishable by its smaller size and paler 

 coloration, the abdomen being pale fulvous instead of deep 

 rufous, the middle of the abdomen nearly white, the throat 

 more whitish, and the upper parts of a paler, more rufescent, 

 and less smoky brown.
