Synonymy. — The name Ornithoponus massonnati was 
introduced by Falcoz for the fly from France which Mas- 
sonnat (1909) described and figured as “Olfersia ameri- 
cana” (the type probably in the collections of the Uni- 
versity at Lyons). Ferris and Cole (1932) were quite jus- 
tified in concluding that Massonnat’s insect was probably 
“an entirely distinct species” from “ americana.” Among 
the larger species of Lynchia (Massonnat gives the length of 
the wing as 8.2 mm.) known to me, Massonnat’s description 
agrees best with L. palustris, although the hairs of the in- 
ner orbital plates and the peculiar setulose covering of the 
wing membrane are not mentioned by him nor by Falcoz. 
There are some features of Massonnat’s drawings, such as 
the very wide frons, that do not fit L. americana, though 
some of them might be due to inaccuracies (there are strik- 
ing differences between the drawings of the head in figures 
40 and 42, particularly in the outline of the postvertex and 
the trend of the sides of the frons). In addition, Masson- 
nat’s fly was taken off a white spoonbill, Platalea leucorodia, 
and thus far I have never seen specimens of true L. ameri- 
cana taken from a wading bird. In view of the fact that 
L. palustris has now been found on a cormorant in Africa, 
it seems highly probable that Ornithoponus massonnati is 
the same species.
