Habitat. — Columbia and Venezuela. 



Maie. — The only difference between this species and S. 

 hoffmanni consists in the general colour of the upperside, 

 which is darker green, the rump of the same colour, with only 

 a few purplish-red feathers near the uppertail-coverts, the 

 wing-coverts are shining green. In S. sophiae they are 

 reddish bronze. Both species are of the same size. The 

 female is less brilliant, and has no spots on the rectrices.
