PROCEEDINGS OF SCIENTIFIC SOCIETIES.

July 3, 1878'—H. W. Batss, Esq., F.L.S., F.Z.S., President, in the 
chair. 
Mr. Basil George Nevinson, of 19, Torrington Square, W.C., was ballotted 
for and elected an ordinary Member. Mr. John A. Finzi, of 105, Gower 
Street, W.C., was ballotted for and elected a Subscriber. 
Mr. F. P. Pascoe exhibited a selection of insects of all orders, as well as 
of Arachnida and Myriopoda, from a collection recently made during a tour 
through Algeria and the South of Spain. He also called attention to a 
remarkable Myriapod, having the cylindrical body of the Julide, but with 
only one pair of legs to each somite. 
Mr. W. C. Boyd drew attention to the food-plant of Elachista cerussella, 
which has been always reputed, both in this country and on the Continent, 
to feed in the leaves of Arwndo phragmitis. He stated that although he 
could not positively assert that the insect never feeds on this reed, he 
much doubted its doing so, as the Arundo does not usually come into leaf 
till the larva of Elachista is half-grown. All the specimens which he had 
bred were found in the leaves of Phalaris arundinacea, a grass which 
somewhat resembles 4A. phraymitis before the flower appears;. hence, no 
doubt, the mistake. 
Mr. H. T. Stainton remarked that although Mr. Boyd had shown that 
the Hlachista larva undoubtedly feeds in Phalaris arundinacea, it must still 
be regarded an open question whether it does not also feed in Arundo 
phragmitis. 
Mr. W. L. Distant, exhibited an Homopteron which had been sent to 
him for identification, through Dr. Sharp, from Mr. Lawson, of Auckland, 
New Zealand. The species was Ricania australis, Walker, and Mr. Lawson 
wrote that it had been observed last year on the dahlia for the first time. 
The markings of the New Zealand specimen were, however, much darker 
than those of the Australian ones, and therefore if, as possible, the insect 
had been introduced from Australia, its arrival must probably have taken 
place some time ago to allow for the process of melanism which had ensued. 
Mr. J. Jenner Weir exhibited two specimens of Leucania turca, with 
several pollinia of Habenaria bifolia attached to the trunk of each, these 
being the only two out of fifty specimens which had the pollinia thus 
attached. He had been able to satisfy himself, by comparison, as to the 
species of orchid from which the pollinia had been removed. Mr. Weir 
also exhibited a specimen of Hipparchia hyperanthus, in which the ocelli 
on the under side of the fore and hind wings were unusually large, oval, and 
with the central white spots ovate and acuminate outwards. The specimen
