1878.] MR. A. G. BUTLER ON NEW LEPIDOPTERA. 381 



Axillaries, wing-lining, and shoulder-edge pure white. Bill, in 

 dried skins, black. 



Wing 1-95, tail l'OO, tarsus 037, culmen 0*37. 



This Flower-pecker closely resembles Myzanthe pygm<zu $ • It 

 differs in wanting the lively olive-green colouring of the upper 

 plumage of M. pygmcea $ , more especially on the uropygium, and 

 the pale yellowish-green lores. The wing too is longer, that of M. 

 pygmcea measuring 1*70. If the sex noted on the label is correct, 

 this Panaon Dicceum is very distinct from M. pygmcea S • If the 

 genus Myzanthe, as distinct from Dicceum, is to be retained, D. 

 modestum should belong to it.
