Specimen Examined.— Belgian Congo: Mongende, one 
male; off a Cormorant, Phalacro corax africanus (Gmelin), 
April 14, 1921 (H. Schouteden). 
I am unable to separate this African specimen from L. 
palustris , commonly found in South America on wading 
birds. The species appears to be most closely related to 
L. hirsuta Ferris, of North America; but that fly is much 
smaller (wing 5 mm. long), has. the basal cell relatively 
shorter, three long setae on each half of prescutum, and a 
long prescutellar on each side. I find no such setae in my 
specimen of L. palustris. L. botaurinorum Swenk, which 
I have seen from Brazil, as well as from North America, 
likewise differs from L. palustris in the smaller size (wing 
5 mm. long) . 
L. palustris is readily differentiated from L. ardese (Mac- 
quart) and related species, found more commonly on wad- 
ing birds, by the larger size, the much wider fronto-clypeus, 
and the absence of setae over an extensive median area on 
the dorsal face of the abdomen.
