Devon, with the wings on the left side, especially the secondary, 

 splashed and streaked with male coloration ; L. icarus, male, also taken 

 in South Devon, measuring only 19 mm. in expanse ; and an example 

 of Glirysoijhanus ■phlcBcts, approaching on the right side ab. schmidtii, 

 from Harpenden, the ground colour of the primary being silvery- white, 

 with the exception of a broad streak of copper colour extending from 

 the base of the wing. — Mr. E. M. Dadd exhibited specimens of Erehia 

 ligea from various German localities ; a small series of E. eicryale ; 

 examples of var. adyte taken at Zermatt and Pontresina ; and of 

 ab. ocellaris and ab. extrema from the Stilfser Joch. Among the 

 Pontresina adyte was a single specimen which might be placed 

 amongst the ocellaris without the slightest hesitation ; although not 

 quite so dark as any of these. The exhibit also included one speci- 

 men of the form euryaloides which is accredited to euryale, occurring 

 with the adyte at Pontresina. — Mr. Dadd also exhibited examples 

 of Lycana corydon : a typical from England, and the Thuringer 

 Wald ; var. apenyiina from the Sabine Mountains ; the form from 

 the South of France ; and a form from Berlin, for which he sug- 

 gested the name borussia, as being distinct from all other forms — 

 first, in the male, by its greater size; secondly, in the extreme width 

 of the black border of the fore wings. He also exhibited a pair of 

 Scodiona fagaria var. favillacearia, and a typical male for compari- 

 son, this being the only form of the species occurring on the heather 

 around Berlin ; and four examples of butterflies which he suggested 

 as hybrids, viz. : L. corydon x bellargus, from Airolo ; Gcenonympha 

 satyrion x paviphilus, from Wengen ; Colias hyale x yalceno, from 

 Oberstdorf ; and Pieris nain x rajJCB, from Berlin, apparently exactly 

 intermediate between the two species. — Professor E. B. Poulton 

 showed a family of eight butterflies bred by Mr. G. F. Leigh, F.E.S., 

 from ova of Charaxes neanthes. Seven of the offspring w^ere C. 

 neanthes, and one C. zoolina ; thus proving, so far as such numbers 

 constitute sufficient evidence, wdnat has long been suspected, viz., that 

 these superficially dissimilar butterflies are forms of the same species. 

 — Dr. F. A. Dixey, M.A., M.D., read a paper, illustrated by lantern- 

 slides, "On Miillerian Mimicry, and Diaposematism. A Reply to Mr. 

 G. A. K. Marshall." 



Novejnber Ath, 1908. — Mr. C. 0. Waterhouse, President, in the 

 chair. — Mr. N. P. Fenwick, Junior, of the Gabies, Esher ; Mr. John 

 Spedan Lewis, of Spedan Tower, Hampstead, and 278-288, Oxford 

 Street, W. ; Mr. W. K. Lister, of Street End House, Ash, near 

 Dover; Mr. Ivan E. Middleton, of 14, High Street, Serampore, 

 Bengal ; Mr. F. E. West, of Peradeniya, Ceylon ; and Mr. J. 

 Swierstray, First Assistant of the Transvaal Museum, Pretoria, 

 were elected Fellows of the Society. — Mr. W. G. Sheldon ex- 

 hibited examples of Melitcea aurinia var. iberica, from Barcelona, 

 taken last May, and examples from various British and continental 

 localities for comparison. Taking into consideration their different 

 appearance and habits, he suggested that eventually this Catalan 

 form of aurinia might prove to be distinct, or at all events a 

 subspecies. — Mr. H. W. Andrews showed a short series of Gymno- 

 soma rotundatum, L., and a specimen of Ocyptera brassicaria, F., 

 two uncommon Tachinids from Glengarriff, co. Cork. — Mr. P. J.
