m the North, and probably occurs in many intervening 

 localities. 



In Scotland it is widely distributed but rare, recorded from 

 Carluke, Edinburgh, and at Balerno and the Isle of May, 

 also at Dundee, Aberdeen, Monci'ieff Hill, Perthshire, where 

 Sir Thomas Moncrieffe found specimens sitting under lumps 

 of unslaked lime! in the Orkneys, and at Unst in Shetland.

 taken, rarely, in Antrim and Donegal. Probably it only

 the Tyrol, and the Valais.
