DIPTERA FROM WENSLEYDALE. 
CHRIS. A. CHEETHAM. 
Diptera records are few from V.C. 65, the North-west Yorks, 
vice county, and the occasion of the Botanical Sectional 
Meeting at Middleham was usred to collect such flies as could 
be found. The weather was by no means ideal for this pursuit, 
but the effort appears justified by the result. Six species are 
additions to the list of the county as a whole : — Boletina 
plana Wlk., Polylepta undulata Winn., Platyura zonata Ztt. 
(i concisa Wlk.), Molophilus cinereifrons Meij., Xanthochlorus 
ornatus Hal. and Neurigona suturalis Fin. The last named 
was not represented in the British Museum collection, and a 
pair of Yorkshire specimens now fill the gap. The following 
have not been recorded previously for the vice county.
