OXYURA 



This group of parasitic flies has been much neglected since the days of Haliday, no doubt from 

 their small size ; many are not so large as an ordinary Aphis, and being parasites on small insects, the 

 opportunity of breeding does not often occur. 



This list contains only forty-one species, these are in the writer's collection, out of 373 enumer- 

 ated in the Rev. T. A. Marshall's ' Catalogue of the Oxyura,' published by the Entomological Society 

 of London, in 1873, ^^^ '* '* impossible to say whether certain species are common or not.
