the larva of plantaginis while feeding. Mr. Helps shewed Dianth&cia capsin- 

 cola, bred from larvse obtained in Norfolk. Mr. Adkin, a fine series of 

 Cyniatophora ridens, bred from pupse received from the New Forest ; the speci- 

 mens shewed a considerable amount of variation, some of the females being 

 very white. Mr. T. E. Billups, specimens of Bracon brevicornis, parasitic 

 upon Ephestia kuhniella, and said that Mr. Marshall once reared the female 

 from the galls of Andricus terminally* Mr. W. F. Kirby had bred six males 

 and one female from Ephestia elutella* Herr Brischke obtained a male from 

 Diaryctia abietella, while Mr. S. Webb, of Dover, had bred a male from 

 Myelois ceratonia. Mr. Fenn read a paper on " British Land and Fresh- 

 water Mollusca," which was followed by a discussion. Messrs. Tugwell, Eice, 

 Carrington, Step, Tutt, South, and others taking part. 



June \Uh, 1888.— J. T. Carrington, Esq., F.L.S., Vice-President, in the 

 chair. Mr. Eobinson exhibited ringed forms of the larvae of Trichiura cratcegi, 

 from Monks wood, and asked whether it was a common var. of the larva. 

 Mr. Tugwell said he had never met with this peculiar form, although in his 

 experience the larva of this species varied considerable. Mr. Lowery, a male 

 Tceniocampa stalilis, taken in copula with a female T. gotMca, and remarked 

 that ova were obtained of which only a few hatched, but the larvse had eventu- 

 ally died. Mr. West, of Streatham, a specimen of a moth reared from a larva 

 found in Switzerland, and which was thought to be Acronycta leporina, also 

 a larva obtained on breaking up some tea chests from China, with pieces of 

 the wood shewing the way the chests had been riddled by these larvse. Mr. 

 Slater said the larva in question was probably that of a species of Buprestidae. 

 Mr. E. Adkin, specimens of Cnephasia musculana, Eriopsela fractifasciana, 

 Phoxopteryx comptana, Eupmcilia ciliella, taken at the Society's excursion to 

 Horsley, on May 29th, and remarked that in his experience the present 

 season was even later than in 1887. The Secretary read a communication 

 from Mr. T. D. A. Cockerall referring to a note by Mr* Frohawk in the 

 "Field" (1887, p. 828), as to his having taken a white banded- example of 

 Sesia culiciformis, at West Wickham. Mr. Cockerell writes that he had 

 hitherto always classed the bands of the Sesidce with the hind-wings, &c. of 

 Arctia, Zygcena, &c, as exhibiting a pigment common to all, which was 

 dimorphic, the two forms being yellow and red ; some species of Sesia have 

 yellow and some red bands, and occasionally a normally a red-banded species 

 would have the bands yellow, but that it should vary to white was quite un- 

 expected and unknown to him, he would therefore ask whether white-banded 

 Sesia were known to any of the members, and was the specimen referred to 

 by Mr. Frohawk known anything of. Mr. Frohawk said he had never met 

 with any white-banded forms of this species. Messrs. Hall, Tutt, Williams,
