Lynchia americana Ferris, 1927, Canad. Entom., LIX, p. 
248, figs. 2 and 3 (fig. 3 erroneously labelled “L. hirsute,” ; 
corrected by Ferris, 1929, Ibidem , LXI, p. 285) ( $ ; off 
Otus asio; Monticito, California). The same remark ap- 
plies to this as to the foregoing record. 
Ornithoyonus americanus C. W. Johnson, 1924, Zoologica, 
New York, V, No. 8, p. 91 (off Buteo galayagoensis; Sey- 
mour Bay, Indefatigable, Galapagos). I have seen this fly, 
which is L. nigra (Perty). Curran’s 0. americanus, from 
Santa Cruz, Indefatigable, (1932, Nyt Mag. Naturvid., 
LXXI, p. 366), probably also was L. nigra, but I have not 
seen the specimen. 
Olfersia americana C. W. Johnson, 1895, Proc. Ac. Nat. 
Sci. Phila., p. 340 (off Screech Owl, Otus asio floridanus ; 
St. Petersburg, Florida). I have seen this specimen, which 
is L. fusca (Macquart). 
Olfersia americana C. W. Johnson, 1913, Bull. Amer. 
Mus. Nat. Hist., XXXII, p. 90 (St. Augustine and Miami, 
Florida). These specimens, seen by me, are L. fusca 
(Macquart) .
