forms of Tephrosia crepuscularia and T. hiimdularia, showing an 

 unbroken line of variation from brown to white and also to grey 

 and black. In addition, he showed several second-brood specimens 

 of both forms, obtained in the past summer by Mrs. Bazzett, of 

 Reading. Mr. Tutt and Mr. Fenn made some remarks on the 

 specimens exhibited. Mr. Tutt read a paper entitled " On the specific 

 identity of Ccenonympha iphis and C. satyrion,'' and exhibited a long 

 series of specimens. The Rev. T. A. Marshall communicated a paper 

 entitled "A Monograph of British Braconidae," part vii. Mr. T. D. 

 A. Cockerell communicated a paper entitled " New Hymenoptera from 

 the Mesilla Valley, New Mexico." Mr. E. Meyrick contributed a paper 

 entitled ''On Lepidoptera from the Malay Archipelago." Dr. Sharp 

 read a paper, by Mr. G. D. Haviland and himself, entitled " Termites 

 in Captivity in England." — H. Goss and W. W. Fowler, Hon. Sees. 



November Ath. — Professor Raphael Meldola, F.R.S., President, in 

 the chair. Mr. McLachlan exhibited a collection of the cast nymph- 

 skins of more than one-third of the species of European Dragonflies 

 from the Departement de I'lndre, France, sent to him by Mons. Rene 

 Martin. Two or three of the species had been reared in an aquarium, 

 but the identification of most of them has been secured by finding the 

 imago drying its wings in the immediate vicinity of the cast skin. 

 Mr. R. Adkin exhibited a long series of Acidalia marginepunctata taken 

 on the sea-coast at Eastbourne, Sussex, during the past eight summers. 

 The series included examples of a bone-coloured form with slightly 

 indicated transverse markings ; others much dusted with black scales 

 giving them a deep grey tone, with well developed markings; and 

 sundry forms intermediate between the two ; also three taken this 

 year, in which the whole of the wings, with the exception of a pale 

 submarginal line, are densely covered with black scales, giving them 

 a similar appearance to the so-called "black" forms that are found 

 among some of the species of Boarmia and Tephrosia. Mr. Horace 

 St. John Donisthorpe exhibited a female specimen of Dytiscus circiim- 

 cinctiis, Ahr., with elytra resembling in form those of the male. He 

 said the specimen had been taken in Wicken Fen in August last. 

 Mr. Tutt exhibited a specimen of Mellinia ocellaris recently taken near 

 Southend, together with a specimen of M. gilvago for comparison ; 

 also four specimens of Argyresthia atnioriella taken by Mr. Atmore last 

 June at Lynn, Norfolk. Mr. Tutt also exhibited a long series of a 

 Melampias which he had captured at Le Lautaret, in the Dauphine 

 Alps, at an elevation of 7000-8000 feet. He observed that the speci- 

 mens exhibited were pecuHar in some very important particulars, 

 combining some of the characteristics of Erehia [Melampias) melampus 

 and M. pharte. He said his attention had been first drawn to this 

 form by some fine examples captured by Dr. Chapman and himself on 

 Mont de la Saxe in 1895. Compared with the Tyrolean examples of 

 M. meiamjms, this form showed a tendency to a lengthening of the 

 fore wings and to an obsolescence of the black dots, thus approaching 

 M. pharte, but the females presented none of the typical characters of 

 the female of M, pharte. On the whole, he felt satisfied that the 

 Mont de la Saxe specimens were a form of M. melampus. Mr. Elwes 

 observed that though all the continental butterflies had been so long 

 studied by European entomologists, he did not think the forni ex-
