to prevent the establishment of the insect in countries where 
the moisture of the atmosphere would probably be fatal to it. 
Mr. Stevens remarked that on different occasions he had 
received the insect in great numbers in bottles from Orizaba.

Siylops taken in Andrena atriceps.—The President exhi- 
bited 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 con- 
founding 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. 
Insects of Kerguelen’s Island—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 abbre- 
viated 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 develop- 
ment of wings useless; and Mr. Jenner Weir remarked that
