L . dukei is strictly Ethiopian and known at present from 
Cameroon, French Congo, Belgian Congo, Abyssinia, Uganda, 
Kenya Colony and Tanganyika Territory. It is the African 
representative of the New World L. nigra , from which it is pos- 
sibly not specifically distinct. 
Like L. nigra , it is known only from diurnal birds of prey. 
Unrecognized Species 
Several of the described, larger species of Lynchia cannot be 
recognized with certainty from the inadequate descriptions. 
Some of them are evidently synonyms of the species recognized 
in this paper. 
1. Lynchia massonnati (Falcoz, 1926). See J. Bequaert, 
1933, p. 72, and the discussion of L. schoutedeni in the present 
paper. 
2. Lynchia villadae (Duges, 1887). See J. Bequaert, 1933, 
p. 76. Possibly a synonym of L. americana (Leach). 
3. Lynchia macquartii (Rondani, 1878). See J. Bequaert, 
1933, p. 78. Possibly a synonym of L. fusca (Macquart). 
4. Lynchia raptatorum (Ad. Lutz, Neiva and da Costa Lima, 
1915). See J. Bequaert, 1933, p. 82. A synonym of either 
L. nigra (Perty) or L. fusca (Macquart). In view of the fact 
that raptatorum was said to occur in several Brazilian localities 
and on four species of diurnal birds of prey, I now consider that 
it was most probably L. nigra . 
5. Lynchia penelopes Weijenbergh, 1881. This, the geno- 
type of Lynchia , has unfortunately not been seen by any subse- 
quent student. It is doubtful whether the type is still in exist- 
ence. Specimens should be collected again from the type host,
