lo 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.

Stylops 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 Andrenae ; 

 Stylops Spencii having been derived by Mi\ Pickering from 

 A. atriceps, and figured by Professor VVestwood 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. Jcnucr Weir remarked that
