This elegant species has considerable relation to Dr, ceneus of 

 Spix and Wagler ; it is, however, not only of a very different 

 colour, and of more slender proportions, but it is also strikingly 

 distinct in the structure of the elongated rostrum, which in Dr. 

 ceneus is acute, mucronated and moveable, whilst in our species it 

 is obtuse, and even rather abruptly truncated. ^
