species. — Mr. A. H. Jones exhibited examples of Melitcea deione, from 

 La Grave, and aberrant forms of M. didyma, from Digne, taken in 

 July last. This is the first record of the former species occurring so 

 far north in the French Alps, and it is noteworthy that the speci- 

 mens showed a nearer affinity to the meridional form than to the 

 var. berisalensis of the Rhone Valley in Switzerland. — Mr. G. C. 

 Dudgeon sent for exhibition a case containing examples of new and 

 little-known butterflies from West Africa, together with notes and 

 descriptions. — Professor T. Hudson Beare exhibited specimens of the 

 very local and rare Trechus rivularis, Gyll., taken at Wicken Fen on 

 September 15th, 1909 ; also of Pseudo-psis sulcata, New., taken at 

 Sandown, Isle of Wight, in haystack refuse, in August last. This 

 genus and species were originally described by Newman on speci- 

 mens taken in the Isle of Wight. The species has never been taken 

 in the island since that date until the present capture. — Mr. H. St. J. 

 Donisthorpe showed examples of the following : — (a) Tyckius pioly- 

 lineatus, Germ., taken at Ditchling by Mr. Dollman and himself on 

 September 9th ; (6) Trechus rivularis, Gyll., taken as above ; the rare 

 Dipteron (c) Meigenia floralis, Fall.; also {d) Phytodecta ixtllida, 

 bred from larvae taken at Chilworth in July last, with the pupa-case 

 on the larval-skin of the beetle ; and the following Braconidae (e) 

 Euphorus histigmaticus, Morley, n. s. male type bred from F. riifa 

 nest from Weybridge, June 15th, 1909 ; females taken hovering over 

 F. riifa nests at Weybridge, July 7th, and Beaulieu Forest, July 

 21st, all of this year. (/) Spilomma falconivihrans, Morley, n. g. 

 et s. male and female bred from F. fusca nest from Porlock, July 

 29th, 1907 ; and (g) Pachylomma buccata female taken at St. Helen's, 

 Isle of Wight, hovering over nests of Lasius niger. — Mr. W. J. Lucas 

 showed a male and female example of Ascalaphus coccajus, and a pair 

 of the same insect near the var. leucocilius, with the golden yellow 

 markings replaced by white. They were taken by the Eev. F. D. 

 Morice, with other specimens, in June of this year, at Geneva. — 

 Mr. G. Bethune-Baker showed a series of Ghrysophanus dorcas, 

 which occurs in North America from Labrador, and Alaska down to 

 Michigan, in marshy localities, and pointed out the peculiar charac- 

 teristic of the egg, which is more Thecloid than Chrysophanid. He 

 also exhibited a finely radiated example of Ghrysophanus hypophlceas ; 

 also a North American species. — Mr. G. F. Leigh exhibited the female 

 parent and twenty-one specimens of the offspring of Gharaxes 

 zoolina neanthes. This result was obtained from ova deposited by 

 the zoolina form of the female, and produced four males and two 

 females like the parent, and fifteen males and nine females of the 

 neanthes form. Last year the same result was obtained in a smaller 

 degree, but the eggs on that occasion were obtained from the neanthes 

 form of the female. Mr. Leigh remarked that although the zoolina 

 forms are consistent in both the wet and dry season, there are two 

 quite distinct forms of the neanthes variety. — Mr. H. Eltringham, 

 M.A., F.Z.S., read a paper on "Edibility Experiments with Larva? 

 and Lizards."— Mr. F. Enock, F.L.S., read a paper on " New British 

 Mymaridae," and illustrated his remarks with a number of lantern- 

 slides of both sexes of the species discovered and described by 

 him. The following papers were also communicated : — " On the
