From P. hrunnea, P. maura differs in the much longer wings, 
which are 6 . 5 to 7 . 5 mm. long and 2 to 2 . 4 mm. wide; the front 
is distinctly shorter, the space between the inner orbits nearly as 
broad as long, the upper margins of the eyes reaching hardly 
beyond the anterior margin of the smooth vertex; the frontal 
lunule is long; the basal, undivided portion of the clypeus is 
rather broad, but very short, dividing almost at once into the 
very long, diverging arms; the anal cell [Cu+lst A] is covered 
with setulse over the anterior half only, the remainder of the cell, 
as well as the axillary cell, being bare. I have selected P. maura 
(Bigot) as the type of the genus Pseudolynchia, because it is not 
only widely distributed, but also one of the few species that may 
be recognized without hesitation. Excellent drawings of P. 
maura have been recently published by Ferris (1925, Philippine 
Jl. Sci., XXVII, pp. 416-417, figs. 2 and 3.) The short, stout, 
black setae on the plantar surface of the middle basitarsus, men- 
tioned by Ferris, are apparently a sexual character. I find them 
in all my male specimens, also of the var. lividicolor ; in the 
female they are replaced by small, slender setae.

This is the common parasite of domestic pigeons in South and 
Central America and the West Indies. I have seen it from the 
following localities : 
Cuba, one male, without host (Poey Coll.) Museum of 
Comparative Zoology, Cambridge. 
Barbados, one male, without host, October 16, 1904 (G. S. 
Evelyn Coll.) Academy of Natural Sciences, Philadelphia. 
Puerto Arturo near Tela, Honduras, four specimens ( 9 d'), 
off domestic pigeons (F. M. Root Coll.) These specimens have 
been recorded as Lynchia maura by Dr. Root (1925, 13th Ann. 
Rept. United Fruit Co. Med. Dept., (1924), p. 209.) 
Manaos, Brazil, one female taken in flight, at the hotel, 
September 14, 1924 (J. Bequaert Coll.)
