Exhibitions, dc. 
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. I’. 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 conyexiuscula, 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 
Thwaitesii. 
Mr. M‘Lachlan read an extract from a Report made to the Royal Society 
on the Natural History of Kerguelen’s Island by the Rev. A. E. Eaton, 
who was attached, as naturalist, to the Transit of Venus Expedition to the 
island. Nearly all the insects were remarkable for being either apterous or 
with greatly abbreviated wings. There were two Lepidoptera, one (only a 
larva) probably belonging to the Noctuina, the other to the Tineina. Of 
the Diptera, one species had neither wings nor halteres; another lived 
habitually on rocks covered by the tide at high water, and its larva fed upon 
a species of sea-weed. All the larger Coleoptera seemed to have their elytra 
soldered together. Mr. M‘Lachlan said that the theory as to the apterous 
condition of the insects was, that the general high winds prevailing in those 
regions rendered the development of wings useless; and Mr. Jenner Weir 
remarked that the apterous condition was correlated with the fact that plants 
under similar circumstances were apetalous and self-fertilising ; and hence it 
was supposed that the existence of winged insects was unnecessary. 
Mr. C. O. Waterhouse exhibited a Chekanops, of which he had discovered 
two specimens under the elytra of Passalus punctiger, from Rio Janeiro,
