SEPTEMBER 14th, 1899. 



Mr. J. W. Tutt, F.E.S., Vice-President, in the Chair. 



Mr. Colthrup, of Barry Road, East Dulwich, was elected a 

 member. 



Mr. Montgomery exhibited two series of Spilosoma mendica. 

 In the first series all the specimens were large, with few spots, 

 and closely resembled the female parent. In the second 

 series black longitudinal lines were well developed in the 

 specimens of both sexes. 



Mr. Colthrup exhibited a long series of Bryophila perla 

 from Eastbourne, including several very nice yellow varieties ; 

 a series of B. muralis {glandifera) from the same place, in- 

 cluding several very pale (naturally) specimens ; together with 

 a variety of Spilosoma menthastri, with a fringe of black round 

 all the wings. It was taken at rest at East Dulwich in 



l8 99- 



Mr. Buckstone exhibited two males in copulation at the 



same time with one female of the coleopteron, Telephones 



nigricans ; a very blue female of Polyommatus corydon, taken 



some years ago at Riddlesdown ; and an example of Chryso- 



phanus phlceas, var. schmidtii, taken at Beckenham in 1886. 



Mr. Edwards exhibited a long bred series of Bombyx cas- 

 tvensis, bred from larvae taken at Rochester, together with 

 preserved larvae, ova, and pupae. The males were, as a rule, 

 very pale, some of them being quite without trace of mark- 

 ings on the fore-wings. Those exhibited were selected from 

 some one hundred and eighty specimens which emerged. 



Dr. Chapman exhibited a representative collection of the 

 species of Lepidoptera taken in August at Arolo, in Switzer- 

 land, a spot some 7000 feet above sea-level. Some of the 

 contrasts were remarkable, such as the truly lowland Cupido 

 minima being found with the Alpine Erebia glacialis. Among 

 the other species found there were E. mnestra, E. epiphron, 

 E. gorge, Setina aurita, and Catharia pyrenczalis. 



Mr. Robt. Adkin exhibited a long series of an Acronycta, 

 taken at " sugar" at Abbott's Wood in June and July last, 

 and bred series of A. tridens and A. psi for comparison. The 

 captured series showed a good deal of variation both in 

 colour and intensity of markings, some of the individuals 

 being lighter than the lightest of the bred examples (which 

 occurred among the tridens), while others were as dark as any. 

 He was unable to say with certainty whether they were all 

 referable to one species, but was of opinion that the majority
