The specimen in the British Museum is the only one I have seen ; 

 but Dours includes the species in his ' Catalogue des Hymenopteres 

 de France.' The British specimen is from Dr. Leach's collection, and 

 has a numbered ticket attached. On reference to his private manu- 

 script catalogue the entry is found : — " June : found settling on a 

 footpath near our house " at Spitchwick, Devonshire.
