Entomological Society of London. — December 3, 1890. — The 

 Rt. Hon. Lord Walsingham, M.A., F.R.S., President, in the chair. 

 Dr. D. Sharp exhibited specimens of Papilio polites, P. erithonius, and 

 Euplcea asela, received from Mr. J. J. Lister, who had caught them on 

 beard ship when near Colombo, m November, 1888. Dr. Sharp read 

 a letter from Mr. Lister, in which it was stated that from the ship hun- 

 dreds of these butterflies were seen flying out to sea against a slight 

 breeze. Many of them, apparently exhausted by a long flight, alighted 

 on the deck of the ship, and large numbers perished in the sea. Lord 

 Walsingham exhibited a coloured drawing of a variety of Acherontia 

 airopos, which had been sent to him by Mons. Henri de la Cuisine, of 

 Dijon. He also exhibited specimens of an entomogenous fungus, 

 apparently belonging to the genus Torrubia, growing on pupee, received 

 from Sir Charles Forbes, and which had been collected in Mexico by 

 Mr. H. B. James. Mr. M'Lachlan expressed an opinion, in which 

 Mr. C. O. Waterhouse and Mr. G. C. Champion concurred, that the 

 pupee were those of a species of Cicada. Mr. F. D. Godman said that 

 at the meeting of the Society on the 3rd October, 1888, he had exhibited 

 a larva of a Cicada with a similar tungoid growth. The specimen was 

 subsequently produced, and the fungus proved to be identical with 

 that on the pupse shown by Lord Walsingham. Mr. R. Adkin exhibited 

 male specimens of Spilosona vie7idica, Clk., bred from ova obtained 

 from a female of the Irish form which had been impregnated by a male 

 of the English form. These specimens were of a dusky white colour, 

 and were intermediate between the English and Irish forms. Mr. F. 

 Merrifield showed samples of a material known as " cork-carpet," and 

 explained its advantages as a lining for cabinets and store-boxes. 

 Dr. Sharp fully endorsed the opinion expressed by Mr. Merrifield. 

 Mr. R. W. Lloyd exhibited specimens of Anistoma Triepkei, Schmidt, 

 and Megacromis incliiians, Er., collected last August at Loch Alvie by 

 Aviemore. Mr. Merrifield read a paper entitled, "On the conspicuous 

 changes in the markings and colouring of Lepidoptera caused by sub- 

 jecting the pupae to different temperature conditions," in which it was 

 stated that the results of many experiments made on Selenia illustraria 

 and Eiinomos autumnaria tended to prove that both the markings and 

 colouring of the moth were materially affected by the temperature to 

 which the pupa was exposed : the markings by long continued exposure 

 before the last active changes ; the colouring, chiefly by exposure 

 during these last changes, but before the colouring of the perfect insect 

 began to be visible, and moderately low temperature during this period 

 causing darkness, a high one producing the opposite effect, and two or
