[November 



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 larvas of Ennomos alniaria. 



The Rev. 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. R. South exhibited a specimen of Lupcrina testacea, bred from a pupa found 

 at the root of a species of Silene at Esstbourne; also a specimen of Lupevina Nickerlii, 

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

 series of Boariuia 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, Homalota 

 hcpatica, Abraus granulum, Anisotoma grandis, Agaricophagus ccphalotcs, ThaJycra sericca, 

 Cryptophagus rujlcomis, Platytarsus sctulosus, &c. He also exhibited a living larva of 

 H clops caru r eus. 



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 Retinia resinclla, received by him from 

 Forres. Lord Walsingham remarked that he had never seen the species in Scotland, 

 but that it was not uncommon in Germany, and he had found it at Hamburgh. 



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

 Lukolela, 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, which were more than 800 miles 

 further up the Congo. 



Lord W T alsingham exhibited preserved specimens of the larva and imago of 

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



Mr. W. White stated that as some doubt had been expressed at the last meeting 

 as to whether the specimen of Nephroma hippia, Fab., var. gaa, Feld., which he then 

 exhibited, was hermaphrodite, he had, with Mr. Griffith's permission, handed the 

 specimen to Mr. G. T. Baker for dissection. 



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 

 dilation or thickening of the median nervules and sub-median nervure in that sex 

 of these species ; but that the apparent 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 entitled, " Notes on the nervules of the fore wings in the'males of 

 Argynnis paphia and other species of the genus." — H. Goss, Hon. Secretary.
