282. EREMOMELA USTICOLLIS. Brown-throated Bush-Warbler. 
This little-known species was obtained by the late Professor Wahl- 
berg in Upper Caffraria (25° S. lat.), according to Sundevall, who 
described it (Oefv. K. Vet. Akad. Forh. Stockh. 1850, p. 103). 
Since that time Mr. T. Ayres has met with it in the Transvaal, and 
he observes :—“ This species much resembles a Zosterops in its habits. 
It sings sweetly, but not loudly ; and when in a tree only a few feet 
overhead, its voice sounds as if it came from a distance. Its food 
consists of insects, for which it may generally be found searching 
actively amongst the upper branches and leaves of trees and bushes.”’ 
Mr. Andersson obtained several specimens near Otjimbinque, his 
first having been shot on the 7th July, 1866, “whilst hopping 
amongst the branches of a lofty tree.’’
