Diptera of Middle America. 
34i 
Eristalis atrimanus Loew. Specimens from Cuba are con¬ 
sidered as this species. This and Wiedemann’s fasciatus must be 
much alike. 
Eristalis bogotensis Macquart. From La Paz, Bolivia and 
Puno, Peru. 
Eristalis conicus Fabricus. Numerous specimens from Bartica, 
British Guiana and one which is typical for the species from Liv¬ 
ingston, Guatemala. This is the first North American record 
so far as I can find. 
Eristalis cubensis Macquart. So far as I am aware this species 
has not been recognized since Macquart named it, but there are 
nearly fifty specimens in our collection from various places in 
Louisiana and Guatemala and one each from Honduras and 
Jamaica agreeing well with its description. C. W. Johnson says 
he has the same from Cuba, the type locality, and my opinion is 
that Williston referred to the same under “21”, Biologia Vol. Ill, 
page 65. 
The species is much like alibifrons but the markings of the 
abdomen are distinctly yellower and the pile of the front is mostly 
black instead of pale. 
Eristalis fasciatus Wiedemann. Numerous specimens from 
Bartica, British Guiana. 
Eristalis furcatus Wiedemann. Specimens from various places 
in Guatemala. Common on the west shore of Lake Amatitlan 
in low ground February 7th. 
Eristalis minutalis Williston. A single example from San 
Pedro, Honduras, February 25, 1905. Collected by E. B. William¬ 
son. 
Eristalis obsoletus Wiedemann. Taken at several stations 
in Guatemala during the first part of February. 
Eristalis philippi Schiner. Three specimens from Chile. 
The type came from Chile. 
Eristalis pusillus Macquart. Said to be the same as Eristalis 
tricolor of Jaennicke. From several places in Guatemala. 
Eristalis ruficeps Macquart. A specimen from Coroico 
Yungas, Bolivia has many characters with ruficeps although it 
may not be that species. 
Eristalis rufiventris Macquart. Rather common, flying near 
the margin of a stagnant pond at Los Amates, Guatemala, January 
18, 1905. Other specimens from San Pedro, Honduras. 
Eristalis scutellaris Fabrieius. From Los Amates, Sanarate 
and Puerto Barrios, Guatemala and from Bartica, British Guiana, 
more than a dozen specimens. 
Eristalis triangularis Giglio-Tos. Collected at Los Amates, 
Gualan, Mazatenango and Santa Lucia, Guatemala. Others 
have taken the species at several stations in Mexico and Brazil.
