gravelly bottom, the spots remained; but if placed in a tank with 

 a sandy bottom the whole of the fish lost the spots within 

 twenty-four hours. If put back into the tank with the gravelly 

 bottom the spots reappeared within the same period. This was 

 no doubt protective, arising through natural selection. Mr. 

 Tugwell expressed an opinion that if the green pupae were 

 placed in a strong light they would probably lose their colour. 



Mr. Turner exhibited a varied series of TriphcBna proniiba, 

 L., and said he was in doubt as to which was the var. innuba, 

 Tr., but that the variation of T. promiba was similar to that 

 of T. comes, Hb. 



Mr. A. E. Hall sent for exhibition a jar containing a large 

 quantity of macaroni, which had been placed on one side for 

 culinary purposes. On being opened for use it was found to 

 be infested with a host of minute beetles. Mr. Billups said the 

 little i^Q.%t\N2Ca Anobium testaceiivi, L., a coleopteron, which at- 

 tacked almost everything eatable, even cayenne pepper and 

 cloves. 



OCTOBER mlk, 1889.

Mr. J. Jenner Weir again exhibited the green-coloured 

 pupse of Pieris napi, L., and said that at the last meeting he 

 exhibited chrysalides of Pieris napi, the metamorphosis of 

 which had taken place under the conditions then stated. 

 It was then thought by some of the members that the 

 apple-green specimens would, if placed in a strong light, 

 lose their colour. He now exhibited the same chrysalides 

 which had been exposed for weeks close to the glass of his 

 greenhouse, in the direct rays of the sun, and it would be 

 seen that not the slightest fading of the green colour had 

 taken place. 



Mr. R. South exhibited a curious specimen of Liiperina 

 testacea, Hb., bred from a pupa found at root of Silene at 

 Eastbourne, and an example of a Luperina, which seemed to 

 be referable to L. nickerlii, Freyer. ; the latter received from 

 Mr. Baxter, who had taken it at St, Anne's-on-Sea, near 

 Preston. Mr. South said that nickerlii was probably only a 

 variety of L. testacea, and the Lancashire specimen appeared 

 to be intermediate between typical 7iickerlii and testacea var. 

 gueneei, Dbld.
