Baccha conjuncta Wiedemann. Two female specimens of this 

 species were taken at Bartica, British Guiana. The head is short 

 and the antenna^ are attached high up and much elongated for a 

 species of Baccha. The front is wide with the sides parallel gi\'- 

 ing quite a different appearance from that present in many s])ecies 

 where the front is distinctly narrowed aboA-e. The two specim.ens 

 differ in having the submarginal cell h\-alino 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 

 1S03, 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 fonn is quite different from most s^^ecies of Baccha, but 

 the characters of the head are nearly nonual. 



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 iii 

 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 stud\' 

 of more than a score of specimens of both sexes I am convinced 

 that the species should be called lineata and that li\'ida should 

 drop into synonomy. Macquart describes and figiires the female 

 and my specimens of that sex are as near to the fip;urc 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 s])ccimens. A 

 male from Puert(^ Barrios, Guatemala, March oth, and a male and 

 female from San Pedro, Honduras, February 21, lOU.'). 



Ocyptamus fuscipennis vSay. Numerous s])ecimens from 

 Slidell, Louisiana. The species is common in all i)arts of Ohio. 



Ocyptamus scutellatus Locw. Four specimens from Boniato, 

 Culja. It is much like dimidiatus Ijut the wings are more suffu.sed 

 and the body is not so highly colored. 



Salpingog.\ster Schiner. 

 Salpingogaster pygophora Schiner. A male specimen from 

 Boniato, Cuba, appears to be this species. The mcsonotum is 

 dark, seutellum light, slighth' darkened across the disk, legs 

 wholly yellow and abdomen reddish-brown throughout.
