Native. Septal, &c. In Forfarshire, according to Mr. 

 G. Don's list. In Argyleshire, by Professor Balfour's list of 

 species seen by himself in Islay or Cantyre. In the Edin- 

 burgh Catalogue, it is recognized as native, though rare, in 

 the counties of the Forth. For ray own part, I find so 

 much difficulty in distinguishing between this and S. vi- 

 minalis, as almost to be prevented thereby from using my 

 own notes on their localities while indicating their distri- 

 bution apart from each other.
