Lynchia americana (Leach) 
Feronia americana Leach, 1817; Hippobosca bubonis Pack- 
ard, 1869. See J. Bequaert, 1933, p. 72. 
The synonymy, distribution and hosts of this fly will be dis- 
cussed fully in a forthcoming paper on the North American 
Hippoboscidae. 
L. americana is one of the most common and widespread 
Nearctic hippoboscids. It is known in the Dominion of Canada 
from Ontario and Nova Scotia; and in the United States from 
Maine, New Hampshire, Vermont, Massachusetts, Connecticut, 
New York, New Jersey, Pennsylvania, Delaware, Maryland, 
the District of Columbia, Virginia, West Virginia, North Caro- 
lina, South Carolina, Georgia, Florida, Alabama, Louisiana, 
Texas, Kentucky, Ohio, Indiana, Illinois, Wisconsin, Iowa, 
Nebraska, Minnesota, Kansas, Colorado and Nevada. Farther 
south it seems to be very rare, as I have seen only one specimen 
from Mexico (Grito) and one from Panama (Juan Diaz). The 
published records from California and the Galapagos were 
based on misidentifications. 
The known host list is very large, but this species is most 
commonly found on diurnal and nocturnal birds of prey and on 
Ruffed Grouse. H. S. Peters (1935, Ann. Carnegie Mus., XXIV, 
p. 57) reported a specimen off an American Egret ( Casmerodius 
albus egretta Gmelin), with a Mallophagan ( Esthiopterum 
botauri Osborn) attached, a most unusual find. The only record 
I have from a passerine host is a specimen taken at White 
Plains, New York, off a White-throated Sparrow, Zonotrichia 
albicollis (Gmelin), by Mr. C. Farley. L. americana has become 
established on the introduced Ring-necked Pheasant, Phasianus 
colchicus torquatus Gmelin. 
Since this paper was sent to press, I received from Dr. A. 
Stone several specimens of L. americana taken off Wild Turkey 
in North Carolina (Durham; Rockingham Co.) and Mississippi 
(Picayune). 
The statement in my earlier paper (1933, p. 75) regarding 
the occurrence of pupae in the ears of Great Horned Owl, should 
be deleted. In C. W. Johnson’s paper it refers to Ornithoica 
vicina (Walker) (cited as O. confluenta).
