Columbia nor to Colombia. There is as yet no conclusive 
evidence that L. americana occurs in Europe, as shown in 
the discussion of L. palustris. 
Synonymy. — The type of Feronia americana (Leach) is 
at present at the British Museum and it is reasonably cer- 
tain that it agrees with the characters here given for the 
species. 
That Hippobosca bubonis (Packard) is identical with L. 
americana (Leach), was recognized by Osten Sacken as 
early as 1878. The type, which I have seen at the Museum 
of Comparative Zoology, shows the correctness of this syn- 
onymy. 
From the description alone it is difficult to recognize 
Ornithomyia villadse Duges, (the type of which is probably 
lost), although there can be no doubt about its being a 
Lynchia. For a time I believed that it might be L. nigra 
(Perty), and I have named specimens of L. nigra, in some 
collections, “villadse.” Recently, however, I received, from 
the Department of Entomology of Kansas University, a fly 
taken off Buteo borealis calurus at Grito, Mexico, and bear- 
ing a manuscript label “resemble a Ornithomyia villadse A. 
Dug.” This specimen agrees in every respect with the 
North American L. americana. I am, therefore, listing 
villadse, provisionally at any rate, in the synonymy of 
americana, pending the examination of further Mexican 
material.
