 Thorax : the disk shining and finely punctured, interspersed with

This is a very variable species and also a very local one ; it has 

 never occurred in any great numbers. I once took about a dozen at 

 Shirley, near Croydon, in August, settling on the flowers of the com-

 at Kingsdown, near Deal, and at Ilfracombe, North Devon, also at 

 Sidmouth, South Devon.
