In view of the absence of any recent British account of this Family, the 
following work will be found of much value, especially from the fact that it 
is written in English :— 
212. LuNDBECK, WILLIAM: Diptera Danica. Part III. Empidide. Copen- 
hagen, 1910. , 
DOLICHOPODID/. 
An excellent general systematic account of this Family is the following :—
