43S -i November, 



Mr. E. B. Poulton exhibited a mounted specimen of the yellow powder from 

 the cocoon of Clisiocampa neustria under a power magnifying 188 diameters. The 

 powder was thus seen to consist of crystals so minute that the form could only just 

 be made out. He said the powder was present in a crystalline form in the malpighian 

 tubes, and was discharged from the anus. A discussion ensued as to the functions 

 of the malpighian tubes, &c, in which Mr. Stainton, Lord Walsingham, Mr. 

 M. Jacoby, Mr. P. B. Mason, Mr. McLachlan, and Dr. Sharp took part. Mr. Poulton 

 also exhibited some photographs of living larvae of Hemerophila abruptaria, showing 

 different depths of colour which had been induced by experiment ; the larvae had 

 been rendered very pale by being surrounded by green leaves and stems only, whereas 

 they became extremely dark when numbers of dark twigs were intermingled with 

 the leaves of the food-plant. All were bred from eggs laid by the same female. 

 Mr. F. Merrifield said that Dr. Chapman had recently obtained similar results from 

 experiments on the larvae of Ennomos alniaria. 



The Eev. Dr. Walker exhibited, and read notes on, a number of Coleoptera, 

 Neuroptera, Hymenoptera, and Diptera, which formed the second instalment of the 

 collection he had recently made in Iceland. 



Mr. E. South exhibited a specimen of Luperina testacea, bred from a pupa found 

 at the root of a species of Silene at Eastbourne ; also a specimen of Luperina Niclcerlii, 

 Freyer, caught in Lancashire last August. He also exhibited, and read notes on, a 

 long series of Boarmia repandata, bred from larvae collected in North Devon. 

 Mr. Poulton, Mr. Merrifield, and Lord Walsingham took part in the discussion 

 which ensued. 



Mr. J. J. Walker, R.N., exhibited a number of Coleoptera collected during the 

 past summer in Cobham Park, Kent. Thirty-three species were represented, amongst 

 which were the following, viz., Eros minutus, Philonthus fuscus, Eonialota hepatica, 

 Abraus granulum, Anisotoma grandis, Agaricophagus cephalotes, Thalycra sericea, 

 Cryptophagus riificornis, Platytarsus setulosus, &c. He also exhibited a living larva 

 of Helops cceruleus. 



Mr. Jacoby exhibited a curious Phytophagous beetle found by Mr. J. H. Leech 

 in the Corea. He stated that he was unable to determine the genus, as was also 

 Mr. J. S. Baly, to whom he had submitted the specimen. 



Mr. R. Adkin exhibited specimens of Betinia resinella, received by him from 

 Forres. 



Mr. W. Dannatt, exhibited a male specimen of Papilio Antimachus, Drury, from 

 Lukolcla, a missionary station about 500 miles from the mouth of the Congo. .He 

 stated that the species, although very rare, had a wide range, as three other specimens 

 of it had been received from the Stanley Falls, more than 800 miles further up the 

 Congo. 



Lord Walsingham exhibited preserved specimens of the larva and imago of 

 Cidaria reticulata, from the Lake District, sent to him by Mr. Hodgkinson. 



Mr. J. Jenner Weir exhibited fore-wings of the males of Argynnis Paphia, 

 A. Adippe, and A. Atlantis, denuded of the scales, in order to show that there was 

 no dilatation or thickening of the median nervules and submedian nervure in that 

 sex of these species; but that the supposed dilatation was produced by a dense mass 

 of scales crowded together on each side of the nervules. He also read a short paper 

 on the subject. — H. G-OSS, lion. Secretary.
