postmentum, and the usually paler colouration. N. schoutedeni has a sharply 

 tapered and distinctly hairy nose tip. N. kempae is East African in distribution, 

 and also has a hairy nose tip.

 Stockholm) ; Stanleyville, 1913 {H. Kohl), syntype soldier from type colony, 

 No. 1037, of N. torquatus (Sjostedt), A.M.N.H. (other syntypes in Naturhist. 

 Riksmus., Stockholm). 



Other Material. Nigeria : Western Region ; Sobo Plain, Obanokoro, 7. hi. 

 1957 (W. Wilkinson), B.M.(N.H.). Eastern Region ; 8m. from Port Harcourt on 

 Owerri Road, 10.xii.1957, and Port Harcourt, 18.xii.1957 (W. Wilkinson), B.M.(N.H.) 



Republic of Congo : Brazzaville, 7.VL1948 {A. E. Emerson), A.M.N.H. 



Congo : 20km. E. of Ndjili and 18km. S. of Leopoldville, 10. vi. 1948, Yangambi, 

 30. v. 1948 and Epulu, 23. v. 1948 {A. E. Emerson) ; Stanleyville, 21.vi.1913 (H. 

 Kohl), 18.iii.1948 (N. A. Weber), all in A.M.N.H. 



A total of n nest series were examined. 



This species has not been collected further westwards than Western Nigeria, and 

 it seems likely that this is near the limit of its range. It is thus confined to the main 

 forest block of West and Central Africa. It was recorded by Emerson (1928) as 

 being a tree-nesting species, but like the rest of those with this habit, it is most 

 frequently collected from runways on trees, and the nest is not easily located.
