DIPTERA FROM THE 

 ALFORD DISTRICT OF LINCOLNSHIRE. 



JAMES EARDLEY MASON, 

 The Sycamores, Al/brci. 



The following is a list of some of the flies taken casually by me in 

 the year iS88, and identified by Mr. G. H. Verrall. Others were 

 rendered impossible of accurate identification by having been carded 

 with gum, like beetles, and the whole series examined thereby made 

 exceedingly awkward to deal with. My indebtedness to Mr. Verrall 

 is consequently tinged with compunction at my having trespassed so 

 largely on his kindness. No one in the county studies the Diptera, 

 to my knowledge. Would it were otherwise. 



This list is an addition to that which appeared at pp. 217 and 218 

 of ' The Naturalist ' for July, 1888.
