Lynchia fusca (Macquart) 
Oljersia fusca Macquart, 1845. See J. Bequaert, 1933, p. 
7 7 1 ; 1940, Rev. Acad. Colombiana Cienc. Ex. Fis. Nat., Ill, 
pt. 12, p. 416; 1943, Jl. of Parasitology, XXIX, p. 132. 
This species will be more fully discussed in a forthcoming 
paper. 
L. fusca is fairly common in Oregon and California, but it is 
also found occasionally in the eastern United States (South 
Carolina, Georgia, Florida, Texas, Tennessee, Kansas, Colo- 
rado, and Michigan). It was originally described from Colom- 
bia, and has also been taken in Panama and Brazil. 
It is mainly found on Owls, more rarely on diurnal birds 
of prey. 
Lynchia wolcotti (Swenk) 
Olfersia wolcotti Swenk, 1916, Jl. New York Ent. Soc., XXIV, p. 132 (no sex. 
Michigan: Ann Arbor, off Buteo platypterus) . 
My surmise that O. wolcotti might be a synonym of L. fusca 
(J. Bequaert, 1933, p. 78) was incorrect. Through the courtesy 
of the late Prof. Myron H. Swenk, I was able to study the type 
now in the Department of Entomology, University of Nebraska. 
Specimens Examined. — Michigan: Ann Arbor, off Buteo 
p. platypterus (R. H. Wolcott. — Holotype). McMillan, off 
Accipiter v. velox (O. M. Bryens, June 6, 1933; recorded also 
by H. S. Peters, 1936, Bird-Banding, VII, p. 13). — Nebraska: 
Lincoln, off Buteo p. platypterus (C. E. Mickel). — Panama: 
El Volcan, Chiriqui, July 6, 1937, off a Hawk (C. B. Worth). 
Apparently a rare species, which has been taken thus far only 
from diurnal birds of prey. 
Lynchia nigra (Perty) 
Hippobosca nigra Perty, 1833; Ornithomyia intertropica 
Walker, 1849; Olfersia acarta Speiser, 1902. See J. Bequaert, 
1933, p. 79 2 ; 1933, Proc. California Ac. Sci., (4) XXI, p. 134; 
^^The reference to Ad. Lutz, Neiva and da Costa Lima, 1915, Mem. Inst. Osw. 
Cruz, VII, p. 182, should be deleted. These authors undoubtedly referred to 
L. fusca some of the smaller Lynchice and their specimens seem to have been at 
least partly L. angustifrons (v. d. Wulp) . The latter is a valid, distinct species, 
not a synonym of L. fusca. The flies off Owls, which Ad. Lutz, Neiva and da 
Costa Lima {op. cit., p. 181) called Olfersia nigra Perty, were almost certainly 
Lynchia fusca (Macquart) .
