usually smaller than continental ones, but that they are identical 

 is certain. This is a very local species, but has been taken 

 plentifully at the Black Mountain, Llantony Abbey, Brecknock- 

 shire, South Wales ; it also occurs in Herefordshire and Mon- 

 mouthshire, and has been captured on Halifax Moor, and on the 

 hills in that district ; it is also found in some abundance at Loch 

 Rannoch in Perthshire. It frequents elevated situations, and is 

 a very active insect, passing with great rapidity from flower to 

 flower.
