Adult female. Head entirely blue like the male, or with only a 

 slight tinge of rufous on the occiput ; nape blaek as in male ; upper

Ohs. Peruvian examples, as well as two from New Granada in the 

 Museum, are not so thickly spotted on the flanks, and are rather 

 stouter in appearance. The males measure 7'3-7'85 in the wing, 

 the females 7*7, so that there is no real difference in the proportions.
