March -KHJi, 1001.— Mr. G. H. Vekrall, Vice-President, in the Cluiir. 



Mr. Willougliby Giirdner, P.L.S., Eeforni Club, Liverpool ; Mr. F. Hopson, 16, 

 Rosslyn Hill, N.W. ; Dr. C. A. Ledoux, Grahamstown, South Africa ; Mr. C. P. 

 Pickett, Leytoii, Essex ; Mr. W. G-. Sinith, 164, Wells Eoad, Knowle, Bristol ; Mv. 

 Or. A. Waterhouse, B.Sc, Sydney, New South Wales; Mr. H. H. Whyman, M.A., 

 Montreal, Canada ; and Mr. F. C. Woodforde, Market Drayton ; were elected Fellows 

 of the Society. 



Mr. C. J. Watkins sent for exhibition a series of lai'ch twigs illustrating the 

 winter condition of Coleophora lai-icella, the special feature being the manner in 

 which the cases of the larva? assimilated in colour with the bark of the larch. Mr. 

 G. B. Eoutledge exhibited a specimen of ITi/drUJa palustris, taken on the wing by 

 Mr. J. E. Thwaytes when sugaring near Carlisle on June 10th, 1899. He said it 

 was the first male taken in that district, and Mr. C. G. Barrett remarked that it 

 was the most definitely marked specimen of any known, and that in the northern 

 locality the lines on the wings seemed to be brought out with greater distinction 

 than in the Fen Country and elsewhere. He also exhibited specimens of Bembidinm 

 Schuppeli, a rare beetle captured on the banks of the river Irthing. Mr. R. 

 McLachlan, Trichopterous larva-cases of the form known as " HeJicops^cJie^' from 

 the Prony Eivcr, New Caledonia, sent to him by Mr. J. J. Walker, E.N. They 

 were large and remarkable for the size of the individual sand-grains of which the_^ 

 were built up. These sand-grains, Mr. Walker informs him, were water-worn 

 particles of the heavier minerals of the river bed, such as chrome, nickel, and iron 

 ores. It is possible that similar cases were alluded to by Hagen in the Stett. 

 Ento. Zeitung, 1864, p. 129, from the Munich Museum. Mr. G. T. Porritt, speci- 

 mens of an almost black form of Acronycta meni/anthidh frotri Skipwith Common, 

 near Selby, and stated that the same form was also common on Strensall Common, 

 near York. For comparison he also showed specimens from the moors near 

 Huddcrsfield. The chief interest in the exhibit consisted in the fact that, in botli 

 the districts where the melanic meiiyanthidia occurred, melanism was not a common 

 feature ; whereas in the Huddcrsfield district, where only the pale form of vieni)- 

 anthidis was taken, melanism was a conspicuous feature in many species, even in 

 and close to the grounds where only the pale menyanthidiii could be found. Mr. 

 H. W. Andrews, a female specimen of AmpMdasys heiuJaria, with hind-wings 

 aborted and scarcely developed, taken at Paul's Cray, Kent, in May, 1896. Mr. H. 

 Eowland-Brown stated that he had seen it announced in the London newspapers 

 that the County Council had appointed a committee of experts to enquire into the 

 feasibility of stocking the London parks with bntterflies, and encouraging those 

 which already existed there. He said that according to the latest observations 

 thirty-nine species of lihopalocera were recorded within, roughly speaking, a ten 

 mile metropolitan limit, but that of these he only knew of Pleris rapa, P. napi, 

 Vanessa Atalanfa, V. urtica, and perhaps one or two others which could, strictly 

 speaking, be said to inhabit the Metropolis itself. A discussion ensued on the 

 subject, in which Mr. A. J, Chitty, Mr. McLachlan, Mr. G. H. Verrall, Mr. H. 

 Goss, and Mr. F. Merrifield took part.— TT. Eowland-Brown and H. Goss, Hon. 

 Secretaries.
