Ophyra (Enescens, Wiedemann. 



A common species throughout South and Central America, 

 extending its range into the southern United States. Evi- 

 dently a strictly New World form up to this time. 



In the larval stages it is found in human excrement and 

 manure, as are most of its congeners, so far as I know. 



Represented in material before me from Monte Video, 

 Uruguay. 



Ophyra leucostoma^ Wiedemann. 



The genotype. Common throughout Europe, Canada, 

 and the United States. One female specimen from Illinois 

 sent to British Museum. 



I have found this species very abundant around chicken- 

 houses in Medicine Hat, Alberta, Canada. It soars like 

 species of the genus Fannia and the Syrphidse. 



Ophyra chalcogaster, Wiedemann. 



Distributed throughout the Orient and extending into 

 Australia. 



Specimens before me are from Southern China, Philippine 

 Islands, India, Ceylon, Siam, Seychelles Islands, Mauritius, 

 and Australia. 



Ophyra anthrax^ Meigen. 



A moderately common European species which ranges 

 into Africa and Asia, 



Localities represented in material before me are Estcourt 

 and Durban, Natal, and Hsikow, near Tientsin, China. 



Ophyra nigra, Wiedemann. 



I suspect that this species has been redescribed as spini- 

 gera, Stein. 



I have seen specimens from Stannary Hills, Queensland.
