I synonymize Pseudolfersia meleagridis with O. coriacea 
after carefully studying the description as well as a speci- 
men (probably a cotype), at the United States National 
Museum, received from Dr. Ad. Lutz. In connection with 
the possible role of 0 . coriacea as a carrier of human leish- 
maniasis (see below), the statement by Lutz, Neiva and da 
Costa Lima that their P. meleagridis occasionally attacks 
man, is of particular interest. 
Olfersia mexicana Macquart (1843, Mem. Soc. Sc. Agric. 
Arts Lille (1842), p. 435; 1843, “Dipt. Exot.” II, 3, p. 278. 
— No sex; Mexico), is possibly the same as 0. coriacea. If 
the identity of these two species could be established beyond 
doubt, Macquart’s name would have to be used. 
The correct wild host or hosts of 0. coriacea in Central 
and South America deserve to be more carefully investi- 
gated. Mr. J. Van Tyne’s specimen from Crax glohicera is 
the first Central American record for which the zoological 
identity of the host is beyond question. I am therefore 
under particular obligation to Mr. J. Van Tyne for the 
privilege of studying this and other hippoboscids collected 
by him on his recent trip to Guatemala. 
In the Peninsula of Yucatan, there are four gallinaceous 
birds that might possibly serve as hosts to 0 . coriacea. (1) 
The ocellated turkey, Agriocharis ocellata (Temminck), 
“pavo del monte ” in Spanish and “Kutz” in Maya (accord- 
ing to Gaumer), is perhaps the most common of the four 
and is particularly abundant in Quintana Roo. (2) The 
crested curassow, Crax glohicera (Linnaeus), usually called 
“Pahuil” by the natives of Mexico and Guatemala, is a 
much rarer bird, though occasionally seen in Quintana Roo. 1 
1 According to a note by the late Dr. G. F. Gaumer (quoted by 
Boucard, 1883, Proc. Zool. Soc. London, p. 459), the flesh of Crax 
glohicera is highly valued as food by the Maya; but the bones are 
always carefully kept away from the dogs and cats, as they are said 
to be very poisonous. E. W. Nelson described the young of C. glohi- 
cera as C. chapmani. He says that the Maya Indians call this bird 
the “ Kamhul whereas they designate the adult as “Bolonchan” or 
“ Bolonchana .”
