Mr. Tutt said he considered the points of difference alluded 

 to were only superficial, and altogether unsatisfactory. The 

 remarks made by him as to strigilis and fasciuncula being 

 identical, were based not on an isolated specimen of the form 

 received from Ireland, but on a long series of the form which 

 was certainly intermediate between the two. With reference 

 to the descriptions of the larvae which had been published 

 from time to time, he attached no importance to these, as no 

 two of them agreed. 



Mr. Tutt, on behalf of Mr. Reid of Pitcaple, exhibited a 

 long, varied series of Agrotis sintulans, Hufn. ; a series of 

 Triphcena comes, Hb., varying from pale to almost black 

 specimens, including some beautifully banded forms ; very 

 bright forms of Melitcza aurinia, Rott. ; also dark examples of 

 Melanippe fliicfuata, L. ; and some six or eight specimens of 

 Abraxas grossulariata,!-,. Mr. Tutt stated that this last species 

 was rare in Aberdeenshire, and had been introduced by Mr. 

 Reid at Pitcaple with some success, and had apparently de- 

 veloped sexual dimorphism, the males becoming darker and 

 the females paler every year. 



Mr. R. Adkin exhibited a long series of Boarmia repandata, 

 L., bred from ova of a moth taken at Westerham. During 

 hybernation the larvae were divided into two equal lots, the 

 one kept on growing privet, the other on growing birch. 

 Although each lot produced some few individuals varying 

 from the majority, there was no marked difference between 

 the bulk of the one lot and the other. 



Mr. R. Adkin also exhibited Boarmia gemmaria, Brahm, 

 bred from ova from a moth taken in his garden at Lewisham. 

 The larvae were similarly treated, the one lot having jasmine, 

 and the other birch, during the winter, and there was no 

 appreciable difference between the moths, all being of the 

 ordinary form. With regard to the larvae, he remarked that 

 in both species a considerable variation existed both before 

 and after hybernation, some individuals being putty-coloured, 

 others of dark shades of brown, while these two extremes 

 were connected by intermediates. He was unable to trace 

 this great variation to environment, as both the light and dark 

 forms had been subjected to the same surroundings. 



Mr. Adkin also exhibited Retinia biioliana, Schiff., and R. 

 pinicolana, Dbl., bred from larvae collected in the neighbour- 

 hood of Poole, the New Forest, and in Surrey. Those from 

 Poole and the New Forest emerged between June 26 and 

 July 27, and were all buoliana. Those from Surrey emerged 

 between July 12 and August 3. From July 12 to 22 all were
