293 DIPTERA OP NORTH AMERICA. [PART II. 



Cette espece est commune et repandue dans une grande partie 

 de l'Amerique. Nous en avons vu des individus de la Pensyl- 

 vanie, de Cuba, de la Guy an e et des differentes parties du Bresil. 



{Translation.) — Bright bronze-green. Wings with two abbreviated 

 fascia?. Antennae black. Feet yellow. Femora black ( £ ) ; hind tibue 

 black ( % ). (Tab. XXI, fig. 1.) 



Wiedemann described this species as having yellow feet in both sexes. 

 According to my observations on a considerable number of specimens, the 

 females alone have the feet of this color, with the exception of the black 

 tarsi ; the males have black femora and hind tibia?. 



This species is common in a considerable part of America. We have 

 specimens from Pennsylvania, Cuba, Guyana, and from different parts of 

 Brazil.
