Mr. J. T. Carrington recorded a case of gynandromorphism 

 in a mackerel which had been sent to the Field from 

 Wolverhampton. He remarked that such a thing was o\ 

 exceedingly rare occurrence. The specimen had on the one 

 side the roe nearly ripe, and on the other a full milt. 



SEPTEMBER loih, 1891. 

 W. H. TUGWELL, Esq., Ph.C, President, in the Chair. 



Mr. W. F. Robinson was elected a member. 



Mr. A. Short exhibited varieties o{ Ai^ctia caia, L. ; in one 

 example the white markings of half of the superior wings 

 were absent. Mr. Short called attention to the fact that the 

 ordinary cream markings of many of the specimens he 

 exhibited were strongly tinged with a rosy colour. Mr. 

 Tugwell remarked that he had noticed this v^hen breeding 

 the species. Mr, J. Jenner Weir said he had once seen a 

 series of this insect arranged according to whether the 

 antennse were of a whitish or blackish colour ; he thought it 

 would be of interest if members would look at their specimens 

 and see whether there were any with antennae of the latter 

 colour. 



Mr. Tugwell exhibited examples of Melitcea aurinia, Rott., 

 from English, Irish, and Scotch localities, and remarked that 

 the Irish examples were the brightest coloured, and that the 

 Scotch had a greyish tone, 



Mr. Frohawk exhibited a bred series of Polyominatus 

 phlceas, L., and remarked on the advantage of rearing this 

 species from ova, as those bred were very much larger than 

 captured specimens. 



Mr. E. Joy exhibited a melanic specimen of Boarmia 

 repandata, L., taken b}^ him at Hampsfelt, near Grange. Mr. 

 Tugwell remarked that it was the same form as Mr. Porritt 

 got in the Huddersfield district. Mr. Tutt stated that Mr. 

 Porritt obtained these black specimens from a very dark fir 

 wood, and inquired whether the specimen now exhibited 

 came from such a wood. Mr. Joy in reply said he captured 

 his specimen on the trunk of a larch tree, on the edge of a 

 larch plantation, which was not at all dark ; in addition, the 

 specimen was very conspicuous on the tree trunk. 



Mr. R. Adkin exhibited a series of Psodos coracina, Esp., 

 bred this spring from Rannoch, and he pointed out that in 

 some of the specimens the band was cut right through. 



Mr. C. Fenn exhibited a long series of Agrotis corticea, 

 Hb., showing the variation of the species at Deal. Mr.
