Exhibitions, de. 
The President exhibited specimens of Stylops taken by himself, in the 
pupa state, in Andrena atriceps, at Hampstead Heath, on the 6th, 9th and 
17th of April last. Mr. F. Enoch, who had been there on the 6th, at an 
earlier hour (between nine and ten o'clock), had been still more successful, 
having captured as many as seventeen males, one of which, however, 
was taken after 2 p.m. The President drew attention to the remarkable 
difference observable in the cephalothorax of the females in these specimens, 
as compared with those met with in Andrena convexiuscula, and remarked 
on the importance of not confounding the species obtained from different 
Andrene ; Stylops Spencii having been derived by Mr. Pickering from 
A. atriceps, and figured by Professor Westwood, in the first volume of the 
‘Transactions’ of this Society, while those obtained by Mr. Thwaites from 
A. convexiuscula had been associated with his name in a monograph of the 
family by the President in the volume for 1874, under the name of Stylops 
Thwaitesei.
