186 Mr. E. Saunders' Synopsis of 



** parasitic on Pamirgus Banksianus,'^ but in the localities 

 where I have taken it, it certainly was not attached to 

 that species, hut probably to some Andrena. As A. 

 Gwynana occurs at Wandsworth in the spring, where I 

 have taken Fahriciana in April, and Gwynana (hicolor) 

 occurs at Hastings close to the spot where I took 

 Fahriciana in August, I think it is very probable that 

 it is also parasitic on that species, and double-brooded 

 like its host.
