DIPTERA OF THE NORFOLK BROADS. 

 BY G. H. VEERALL. 



During the last half of June, I had the opportunity of collecting 

 among the Norfolk and Suffolk Broads, and a list of my captures, with 

 a few notes, may be of interest. The neglect this district has ex- 

 perienced of late years, and the astonishing ignorance as to its 

 character and extent, which so widely prevails, are, I suppose, 

 attributable to the late inaccessibility except by boat ; but by making 

 Yarmouth the head-quarters, and using the new East Norfolk Railway, 

 many of the Broads, such as Hickling, Ormesby, Eilby, and Martham, 

 are fairly accessible, and this is by far the most convenient method of 

 working the district, as scarcely any accommodation can be obtained in 

 the villages. The lakes are grand sheets of shallow fresh water, with 

 reedy, marshy, or well-timbered edges, affording most perfect spots 

 for a naturalist to work on, and they have apparently changed but 

 little for many centuries, hence they teem with life both entomological 

 and ornithological. 



My hopes of obtaining some novelties to Britain were not doomed 

 to disappointment, as besides what may remain among my unnamed 

 residuum, I certainly obtained in quantity one very lovely Dolichopus 

 (Gymnopternus chah/beus, Yv T ied.) quite new to Britain, and a speci- 

 men of the curious and puzzling Graphomyia picta, Zett. 



As localities for English Diptera are very few, I give a full list of 

 the species I have recognised : when no locality is given, the species 

 may be considered of general distribution.
