June, 1914.] Diptera of Middle America. 341 



Eristalis atrimanus Loew. vSpecimens from Cuba are con- 

 sidered as this species. This and Wiedemann's fasciatus must be 

 much ahke. 



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 

 Jainaica agreeing well with its description. C. W. Johnson says 

 he has the same from Cuba, the type locality, and my opinion is 

 that WiUiston 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 WiUiston. 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 

 IS, 1905. Other specimens from vSan Pedro, Honduras. 



Eristalis scutellaris Fabricius. 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 Liicia, Guatemala. Others 

 have taken the species at several stations in Mexico and Brazil.
