DltAPETIS. 381 



Range. Europe, India, Burma, Java, North Africa, North 

 America, St. Vincent, Chile, Australia. 



Life-history unknown. 



Drapetis is conspicuous amongst Empids on account of its short 

 thick-set body, short robust legs, and the curved 1st, 2nd, and 3rd 

 veins, in conjunction with the absence of the discal and anal cells. 

 The flies frequent fields and meadows in preference to woods, 

 running swiftly over the leaves. Lundbeck thinks some species 

 hibernate in the imago stage. 



One or two subgenera have been set up on, I think, rather 

 weak or inconstant characters, and all the species are here 

 retained under the one generic heading.
