where, with abundant visitors among the Syrphidae. We 
gave figures of the number of insects visiting it on the 
Scarborough cliffs in the first part of our paper ; there the 
Bombi make 55-3 per cent, of the visitors ; at Clova they 
make 38-2 per cent. Long-tongued flies appeared in greater 
numbers at Clova than at Scarborough.
