Webb, his two specimens of Plus-ia monefa. Mr Bescherner, foreign Papilios. Mr. 

 Stott, a very variable series of Charceas graminis. Mr. P. Sehill, Parnassius Apollo 

 and P. Phaehux, vcith specimens of Papilio Machaon, showing the marked difference 

 between English and foreign specimens. — F. N. Pierce, Hon. Sec, 143, Smithdown 

 Lane, Liverpool. 



Entomological Society of London: December 3rd, 1890. — The Right Hon. 

 Lord Walsingham, M.A., F.R.S., President, in the Chair. 



Mr. John Gardner, of 6, Friar Terrace, Hartlepool ; and Mr. Samuel James 

 Capper, F.L.S., of Hiiyton Park, Liverpool, were elected Fellows of the Society. 



Dr. D. Sharp exhibited specimens of Papilio Polites, P. Erithonius, and Euplcea 

 Asela, received from Mr. J. J. Lister, who had caught them on board ship when near 

 Colombo, in November, 188S. Dr. Sharp read a letter from Mr. Lister, in which it 

 was stated that from the ship hundreds 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 

 Atropos, 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 Torruhia, growing on pupae, received from Sir Charles Forbes, and which had 

 been collected in Mexico by Mr. H. B. James. Mr. McLachlan expressed an opinion, 

 in which Mr. C. O. Waterhouse and Mr. Gr. C. Champion concurred, that the pupae 

 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 fungoid growth. The specimen was subsequently produced, and the fungus 

 proved to be identical with that on the pupae shown by Lord Walsingliam. 



Mr. R. Adkin exhibited male specimens of Spilosoma mendica, 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 Anisotoma Triepkei, Schmidt, and 

 Merjaci-onus inclinans, 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 Lepiduptera caused by subjecting the pupae to different 

 temperature conditions ;" in which it was stated tiiat the results of many experi- 

 ments made on Selenia illustraria and Ennomos 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, cliiefly by exposure during 

 these last changes, but before the colouring of the ptrfect insect began to be visible, 

 a moderately low tcmpei-ature during tliis period causing darkness, a high one pro- 

 ducing the opposite effect, and two or three days at the right time appearing in some 

 cases sufficient. Dryness or moisture applied during the whole pupal period had
