72 fAugust, 18G6. 
Entomological Society of London. 2nd July, 1866. — Sir John Lubbock, 
Bart., F.R.S., President, in the Chair. 
The Hon. Thomas De Grey, M.P., of Arlington Street, Piccadilly, and Merton 
Hall, Thetford, and Christopher Ward, Esq., of Halifax, were elected Members. 
The President invited the Members to spend the day with him at Parnborough, 
on Saturday, the 11th of August next. 
Mr. Stainton exhibited a seed-head of Typha latifoUa which had been sent to 
him by the Hon. T. De Grey, and which was infested with the larvso of Laverna 
phragmitella; and also a series of the Gelechia bred from the galls of Gypsophila 
sacoifraga. He mentioned that he had received a letter from M. Milliere, stating 
that the rye crops near St Etienne, in Prance, had suffered greatly from the ravages 
of a larva which he (Mr. S.) believed to be that of Ochsenheimeria taurella. 
Mr. Bond exhibited an example of Dianthoecia ccesia, specimens of which had 
recently been taken by Messrs. Gregson and Hopley, in the Isle of Man; and 
specimens of Sesia philanthiformis bred from pupse sent by Mr. Greening from the 
same locality : together with a Phycita which he thought might be new. He further 
exhibited a series of remarkably large examples of Papilio Machaon, and stated that 
most of those bred this year were very fine. 
Mr. Edwin Shepherd exhibited an old example of Dianthcecia ccesia from the 
late Mr. Bentley's collection, which was said to haTe been captured in Yorkshire ; 
it was identical in appearance with the Isle of Man specimens. 
Mr. E. Saunders exhibited some Lepidoptera from Mexico, including a fine 
gynandromorphous example of a species of Euterpe. 
Mr. Stevens exhibited specimens of Dicranocephala Wallichii from Northern 
India, and D. Bowringii from Southern China. 
The Rev. Douglas Timins sent some notes on the larvas of Charaxes Jasius and 
Melitcea provenciaUn, which he had bred in England from continental larvae. 
Mr. Pascoe made some further remarks on the insects found in cylindrical holes 
in the snow fields of Switzerland (see Proceedings for April 3rd, 1865, Ent. Month. 
Mag., Vol. I., p. 284), in connection with a paper by Mr. Albert Miiller, in the July 
number of the " Zoologist," in which he referred to Von Tschudi's " Thierleben der 
Alpenwelt," p. 465, the latter stating that insects fly on the snow, apparently for 
the purpose of absorbing oxygen. 
Professor Brayley alluded to an old idea that melting snow contained free 
oxygen. 
Professor Westwood stated that bees, during sunny weather, when the snow 
was on the ground, had a habit of settling on it, and were thus killed. 
The President called attention to a paper by M. Balbiani on the generation of 
Aphides, published in the June number of the " Comptes Rendus," in which the 
author advances the theory that these insects are true hermaphrodites. 
Professor Westwood mentioned, in regard to this subject, that he had been 
much puzzled at observing, that on some rose-trees which were placed away from 
any overhanging trees or shrubs, the young buds, morning after morning, were 
each occupied by a fat apterous Aphis, although the plants had all been carefully 
cleaned on the preceding day. He could not imagine by what means they had come 
there. Mr. Edward Sheppard said he had observed similar occurrences.
