 London district ; some years ago it w^as met with sparingly in 

 Kent, during the month of July, in a lane leading from Betsoiv 

 to Green Street Green, at the side of Darenth Wood; in 1851 

 ** its metropolis '' was discovered in Sandown Bay, at the back 

 of the Isle of Wight ; here it abounded in the month of July ; 

 it is parasitic on Halictus rubicundus and H. leucozonius.
