species.—Mr. A. H. Jones exhibited examples of Melit@a deione, from 
La Grave, and aberrant forms of MW. 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 Pseudopsis 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) Tychius poly- 
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 pallida, 
bred from larve taken at Chilworth in July last, with the pupa-case 
on the larval-skin of the beetle; and the following Braconidex (e) 
Huphorus bistigmaticus, Morley, n.s. male type bred from F. rufa 
nest from Weybridge, June 15th, 1909; females taken hovering over 
F. rufa nests at Weybridge, July 7th, and Beaulieu Forest, July 
21st, all of this year. (f) Spelomma falconivibrans, Morley, n. g. 
et s. male and female bred from fF’. fusca nest from Porlock, July 
29th, 1907; and (g) Pachylomma buccata female tuken at St. Helen’s, 
Isle of Wight, hovering over nests of Lasiws niger—Mr. W. J. Lucas 
showed a male and female example of Ascalaphus coccajus, and a pair 
of the same insect near the var. lewcocilius, with the golden yellow 
markings replaced by white. They were taken by the Rey. F. D. 
Morice, with other specimens, in June of this year, at Geneva.— 
Mr. G. Bethune-Baker showed a series of Chrysophanus 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 Chrysophanus hypophleas ; 
also a North American species.—Mr. G. F. Leigh exhibited the female 
parent and twenty-one specimens of the offspring of Charazes 
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.8., read a paper on “ Edibility Experiments with Larvee 
and Lizards.’’—Mr. F. Enock, F.L.S., read a paper on “‘ New British 
Mymaride,”’ 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
