Zoology. 421 



DIPTERA (Flies). 



It is rather unfortunate that the district has never been properly 

 worked for Diptera, and that the list offered must be looked upon 

 as at the best a very incomplete instalment of the number of the 

 species actually to be found in the district. It is composed almost 

 entirely of two lists, one by H. W. Andrews, F.E.S., of Welling, 

 and the other (Nematocera) by Stanley Edwards F.Z.S., F.L.S., F.E.S., 

 of Blackheath. Mr. Andrews, writing of his share in the list, says 

 that it ' ' cannot be taken as a complete one of the district, it 

 merely records those I have personally met with, and those 

 specially recorded in Verrall's " British Flies, Syrphidae," and 

 his annotated " List of British Dolichopodidae," as occurring in 

 the district. I have not so far attempted many families, and 

 have not touched the Nematocera at all." A few records by 

 H. J. Turner are the only addition to these notes. H. W. Andrews' 

 records are not initialled. Of the others : 



S.E. = STANLEY EDWARDS, F.Z.S.,F.L.S., F.E.S. 

 H.J.T. = HENRY J. TURNER, F.E.S. 



It is trusted, however, that this may form a basis for a more 

 complete list by future workers.
