honey-producing blossoms. It is particularly fond of gardens 

 and lanes, but is also to be met with in the more open rides 

 of woods, and is found sparingly all over the South of Eng- 

 land, though rarely in Cornwall ; also throughout the rest 

 of England, becoming more common in the Midland and 

 Western counties and less so in the Eastern. Probably to 

 be found throughout Wales, and certainly at Pembroke in 

 the extreme west. In Scotland at Hawick and commonly 

 in Wigtownshire, also in Ayrshire and elsewhere in Clydes- 

 dale, Cantire and other parts of Argyle, Perthshire, Aber-

 and the Orkneys. Generally common in Ireland. Abroad 

 it probably has a wide range, but its localities seem to be 

 mixed with those of P. iota. It extends through Central 

 Europe, the temperate parts of Northern Europe. Northern 

 Italy, and some portions of Russia, if not farther.
