almost entirely of different shades of green, blue, and 
cinnamon-brown, the latter of which is usually called 
ferrugineous or bright rust colour. All the species 
are confined to the warm latitudes of the Old World, 
and only one migrates to the colder countries of

the Abyssinian, while that which has been named
