bred from November 21st, to December 13tli last, from Eastbourne. Mr. ITarrison 

 reported that the results of tlie cross breeding of the forms of Aplecla nebulosa by 

 Mr. Mansbridge were gvcj -x thompsoni ^=a\\ rohsoni, and ro/yso/n' x grey = 50 per 

 cent, of each of these forms. A long and interesting discussion took place as to the 

 oviposition and early life of the larva of the j53geriids. It was noted that in the 

 first instar the larvae of several species were hairy and presumably external feeders. 



Thursday, February 2^th, 1909.— The President in the Chair. 



Mr. Stone, of Clapham, was elected a member. 



Dr. Hodgson exhibited series of Nemoria viridata, taken in 190fi — 8 in Lanca- 

 sliire and Surrey, and commented on the forms shown, including ab. concaoilinea. 

 He also showed a 3rd brood specimen of Celastn'na argiolus, in which the blue was 

 almost wholly replaced by dull grey. Mr. West (of Q-reenwich), a cabinet drawer of 

 Coleoptera, the first of the re-arrangement of the Society's collection. Mr. Main, 

 for Mr. Baldock, a yellow variety of Euchelia jacobxse, from Norfolk, and three fine 

 specimens of the rare Papilio mechowianus, from Central Africa. Mr. McArthur, 

 specimens of Anarta cordigera from Rannoch, and read notes on its habits and 

 habitat. Mr. H. Moore, a gynandi-ous example of Papilio clearchus (?), from South 

 America, right side <? , left side ? . Mr. Newman, Aglain urtics; var. ichiiusa, with 

 sagittate blue spots on the hind margin ; Dryas paphia, with much radiated black 

 markings; " black " Limenilis sibylla; a straw-coloured variety of Rumicia phlseas; 

 the unique pale grey form of Smerinthus ocellatus, bred by him in 1902 ; and 

 several Nisoniades tages var. taran. — Hy. J. Turner, Hon. Secretary. 



Entomological Society of London : Wednesday, March 3ri, 1909. — 

 Dr. F. A. DiXEY, M.A,, M.D., President, in the Chair. 



Mr. Fi'ancis Hamilton Lyon, of Addlestone, Surrey, was elected a Fellow of 

 the Society. 



Mr. L. B. Prout, on behalf of himself and Mr. A. Bacot, brought for exhibition 

 a very extensive series of Acidalia virgularia, Hb., bred in ten successive generations 

 from various crossings of the London and Hyeres race, which had been undertaken 

 with a view to the further study of Mendelism. The results showed non-Mendelian 

 inheritance, there being no segregation with pure and hybrid forms in definite pro- 

 portions, and supporting Mr. Bacot's opinion that such were only to be expected in 

 cases of hybridization of forms in which Natural Selection had virtually eliminated 

 intermediates. Mr. H. M. Edelsten showed a living pupa of Pieris rapse attached 

 to a blade of Clivia, the deep green pigment assimilating closely to the coloration 

 of the leaf. Mr. R. Adkin, what appeared to be a hybrid between Zygsena fili- 

 pendulas and Z. achillese, taken by Mi-. A. W. Renton in the neighbourhood of 

 Oban, N.B. Mr. J. W. Tutt expressed his opinion that the form was an aberration 

 of Z. Jilipendulx and that in nature the two species were unknown to pair. 

 Mr. Hamilton H. Druce communicated a paper " On some new and little known 

 Hesperiidse from Tropical West Africa." Mr. G. A. K. Marshall, on " Birds as a 

 1 actor in the production of Mimetic Resemblances in Butterflies." He explained 

 that one of the chief criticisms directed against the theories of mimicry was to the 

 effect that, on the whole, birds did not destroy butterflies to any appreciable
