Similar to T. cceruhscens, but with tho belly and flanks more or 

 less fulvous in both sexes. 



Jlab, South-eastern Brazil. 



I follow Graf v. Berlopsch in allowing this species to bo possibly 

 distinct from Th. candescens, but I have not a sufficient series to 

 clear up the point satisfactorily. As regards White's specimens 

 from Misiones, which he refers to this species, I could not venture 

 to separate them from T. ccendescens.

The cinereous cap of the male and chestnut head and neck of
