Baccha conjuncta Wiedemann. Two female specimens of this 
species were taken at Bartica, British Guiana. The head is short 
and the antennas are attached high up and much elongated for a 
species of Baccha. The front is wide with the sides parallel giv¬ 
ing quite a different appearance from that present in many species 
where the front is distinctly narrowed above. The two specimens 
differ in having the submarginal cell hyaline in one and plainly 
yellowish in the other. 
Baccha cultrata Austin. A female specimen from Puerto 
Barrios, Guatemala, agrees well with Austin’s figure and descrip¬ 
tion in the Proceedings of the Zoological Society of London for 
1893, page 151. Austin’s specimens were taken in Brazil and this 
record extends the range for the species much to the northward 
and establishes it as a member of the North American fauna. The 
general form is quite different from most species of Baccha, but 
the characters of the head are nearly normal. 
Baccha clavata Fabricious. Specimens of this common 
species are before me from many localities ranging from South 
America to Wisconsin. I have taken it plentifully in Ohio, 
Louisiana and in several localities in Guatemala and Honduras 
where it occurs from the Atlantic to the Pacific. 
Baccha lineata Macquart. This is a very common species in 
Guatemala and numerous specimens are at hand from Honduras 
and British Guiana. The coloration of the body and wings varies 
somewhat in a series of specimens. Williston suggests that livida 
Schiner may be the same as lineata Macquart and from my study 
of more than a score of specimens of both sexes I am convinced 
that the species should be called lineata and that livida should 
drop into synonomy. Macquart describes and figures the female 
and my specimens of that sex are as near to the figure certainly 
as most identifications are to his reproductions. 
Ocyptamus Macquart. 
Ocyptamus dimidiatus Fabricius. Plentiful in a number of 
localities in Guatemala and Honduras. 
Ocyptamus funebris Macquart. Three specimens. A 
male from Puerto Barrios, Guatemala, March 5th, and a male and 
female from .San Pedro, Honduras, February 21, 1905. 
Ocyptamus fuscipennis Say. Numerous specimens from 
Slidell, Louisiana. The species is common in all parts of Ohio. 
Ocyptamus scutellatus Loew. Four specimens from Boniato. 
Cuba. It is much like dimidiatus but the wings are more suffused 
and the body is not so highly colored. 
Salpingogaster Schiner. 
Salpingogaster pygophora Schiner. A male specimen from 
Boniato, Cuba, appears to be this species. The mesonotum is 
dark, scutellum light, slightly darkened across the disk, lcg^ 
wholly yellow and abdomen reddish-brown throughout.
