objects it is not so obvious, and from the former sufficing 
it is overlooked. 
To return from this digression, I cannot with Van der 
Linden consider the Philanthus emarginatus of Panzer as 
a variety of the present species, for he figures it with the 
legs entirely yellow, and also describes it so, with the ex- 
ception of the apex of the posterior tibiz; nor does Pan- 
zer’s Phil. sabulosus belong here, as will be seen in my 
sixth species. I have found this very beautiful insect in 
great abundance in Battersea Fields, where it forms its 
burrows in the beaten pathways of a market garden, and 
supplies its young with the Halictus rubicundus, H. fulvo- 
cinctus, and H. leucozonius. I have also found it equally 
abundant in a sandy lane near Green Street Green, in 
Kent, where occasionally very highly coloured specimens 
i 
occur.
