DELTOID ES. 301 



wanting ; also found locally in the Midland Counties, and in 

 Cheshire, Lancashire, Yorkshire, and Cumberland — doubtless 

 throughout England where properly looked for. In Scotland 

 it seems almost confined to the south-west, being recorded 

 by Mr. Morton at Carluke, and also found in the Solway 

 district. In Wales it is doubtless generally common, since 

 I have found it so at Pembroke. In Ireland widely dis-

 and Antrim. Abroad it ranges through Central Europe, and 

 is found in the South of Sweden, Finland, Portugal, Piedmont, 

 Southern Russia, and Tartary.
