3. EUPHONIA. 59 



This rather extensive genus is widely diffused in the Neotropical 

 Eegion, from Southern Mexico to Bolivia and Paraguay. It is 

 rejiresented by a small group of three species in the Antillean Sub- 

 region, but in the Patagonian Eegion is absent, except that one 

 species occurs in the Sierra of Cordoba and probably in other 

 northern wooded districts of the Argentine Republic. 



The true Euphonia; are all of smaU size, and as regards the male 

 sex mostly of brilliant colours. They are arboreal in their habits 

 and fly little, but are said to congregate in considerable numbers in 

 fruit-bearing trees, eating iucessautly. Little is known of their 

 nesting ; but eggs of E. elegatitissbna, taken at Juquila in Oaxaca, in 

 May, were of a creamy white with a few scattered spots and blotches, 

 principally at the larger end, of two shades of brown (P. Z. S. 1859, 

 p. 37«).
