298 DIPTERA OF NORTH AMERICA. [PART II. 



Cette espece cst commune et repandue dans une grande partie 

 de 1'Amerique. Nous en avons vu des individus de la Peusyl- 

 vauie, de Cuba, de la Ghiyane et des differentes parties du Brcsil. 



(Translation.) Bright bronze-green. Wings with two abbreviated 

 fasciae. Antennae black. Feet yellow. Femora black ( ) ; hind tibise 

 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 tibise. 



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

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

 Brazil.
