fig. 3 (no sex given; on domestic turkey, Meleagris 
gallopavo, in Pernambuco and Sao Luiz do Maranhao; 
on Tinamus solitarius Vieillot in Minas Geraes or 
Espiritu Santo; all localities in Brazil). 
Colonia Santa Maria (near Puerto Morelos), in the 
northern part of the Territory of Quintana Roo, May, 1929 
(G. C. Shattuck). This specimen was received from a 
Maya hunter, who said he found it on an ocellated turkey, 
Agriocharis ocellata (Temminck). Territory of Quintana 
Roo (“Herrera, 1919, said to cause a disease in man.” — 
U. S. Nat. Mus.). 
I have also seen specimens from Peten, Guatemala 
(Oliver Ricketson, Jr.; as “bay-sore fly,” received through 
Dr. Thomas Barbour) ; Uaxactun, Peten, Guatemala, off 
Crax globicera (Linnaeus), April 15, 1931 (J. Van Tyne) ; 
Upper Chagres River, Panama, off turkey (U. S. Nat. 
Mus.) ; Rio Colorado, Bolivia, off Penelope sp. (W. M. 
Mann. — U. S. Nat. Mus.) ; and Pernambuco, Brazil, off 
turkey (received from Dr. Ad. Lutz as P. meleagridis . — 
U. S. Nat. Mus.). 
The following characters may aid in separating 0. cori- 
acea from other closely allied species of Olfersia. Frons 
rather narrow, very little wider than an eye. Posterior 
orbits and postvertex about equally produced behind, the 
orbits short and divided from the hind margin of the post- 
vertex by a very shallow sinus. Postvertex with a slight 
transverse depression, dividing it into a short, anterior, 
dull, alutaceous area and a much longer, posterior, smooth 
and shiny area. Fronto-clypeus not covering nearly the 
whole palpi; its apical, interantennal portion rather nar- 
row and not striate; the free, terminal arms short and 
broad, not appreciably grooved above. First basal cell ( R ) 
long and narrow, nearly parallel-sided in its apical half; 
second basal cell (M) long, the second section of the fourth 
longitudinal vein (Ml + 2) being about as long as the first 
section of the fifth (M3 + Cul) ; third and fourth longitudi- 
nal veins (R4 + 5 and M l + 2) not setulose; first longitudinal
