 The species, which is common in France and Germany, has not been 

 recorded hitherto in Britain. — Mr. A. J. Chitty exhibited an hermaphro- 

 dite of the ProctotrupidsB, probably one of the Spilomicrinte, Aspm. ; 

 a sand-wasp, without wmgs, taken by Mr. Poole, running on a beech- 

 trunk, named by Mr. Saunders as Didineis lunicomis ; and the male 

 Apwn semivittatum, Gyll. {(jeniiari, Walt.), taken many years ago by 

 Mr. Walton, near the Tivoli Gardens, Margate, together with a female 

 specimen of the same species, discovered while sweeping long grass 

 near the Chequers Inn, Deal, on September 26th, 190i. — Mr. F. 

 B. Jennings exhibited a male and female example of the Dipteron 

 Helophilus transjwjux, L., taken from thistle-heads in the marshes 

 at Edmonton last July, and a specunen of Stenoptenjx hirundinis, a 

 parasite on swallows and martins, found on Box Hill, Surrey, in 

 August. — Mr. G. T. Porritt brought for exhibition specimens of 

 Odontopera bidentata ab. nigra, and stated that the melanic form was 

 rapidly increasing in the Wakefield district of South Yorkshire. — 

 Dr. F. A. Dixey showed specimens of South African Pierine butter- 

 flies, taken by him in the dry season this year, further illustrating 

 their forms; and with them, for comparison, specimens taken by other 

 collectors during the rains. — Mr. 0. E. Janson exhibited a male and 

 female specimen of Ornithoptera chimccra, Rothschild, and some 

 remarkable species of Delias, collected recently by Mr. A. S. Meek 

 in the mountain regiou of British New Guinea. — Commander J. J. 

 Waliier, on behalf of Mr. A. M. Lea, Government Entomologist of 

 Tasmania, showed a specimen of a Buprestid beetle, Cyria imperialis, 

 Don., having, in addition to the normal fore-leg on the left side, two 

 supplementary fore-legs originating from separate coxfe. — Mr. G. C. 

 Champion exhibited male and female examples of Tetropium crawshayi,

 last in the bark of larches at Leighton Buzzard. — Mr. E. R. Bankes 

 showed the unique specimen of Depressaria emeritella, Stn., from an 

 unknoY\rn locality, on which the species was added to the British List 

 many years ago ; a specimen of Cerostoma asperella, L., discovered by 

 Mrs. Hutchinson near Leominster, on September 21st, 1881, and only 

 taken, as regards Britain, in Dorset (formerly), and Herefordshire very 

 rarely ; and various specimens recently acquired from the collection of 

 the late Dr. P. B. Mason and labelled by Haworth himself, showing 

 the method of explaining his identification of the species, described 

 by him in his 'Lepidoptera Britannica,' published 1803-1828. — 

 Mr. A. Bacot, who exhibited long series of Truphtcna cornis, bred 

 through three generations, and brought together to test the relative 

 proportions of melanic to non-melanic forms and the possible range of 

 variations to be obtained from a single pair of parents, announced that 

 the results of the second and third generations seemed to be capable 

 of " Mendelian " explanation. — Mr. R. Shelford exhibited larvaB of 

 Collyris einaryinatus, Dej., from Borneo, and said that it was certainly 

 unusual to find a predaceous larva with mouth-parts qualified to 

 excavate burrows in wood. He also showed larvae and pupte of 

 Mormolyce, together with a specimen of a fungus [Folyponis) split open 

 to show the lenticular chamber excavated by the larva, to which access 

 was obtained by so small an orifice that it was surprising that the
