Exliihitions, etc. 



Mr. McLachlan exhibited a collection of the cast nymph- 

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

 Dragon-flies from the Departemeut 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 margine- 

 punctata 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 mark- 

 ings ; 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 speci- 

 men of Bytisciis circHincinctHs, 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 MdUvia {Xanthia) 

 ocellaris, captured by Mr. F. Whittle in September, 1894, 

 and for comparison a specimen of M. (/ilvago, the latter species 

 being common in the locality, and at the time that the speci- 

 men was captured. He referred to the fact that M. ocellaria 

 was usually captured in the same localities as M. gilvat/o, and 

 drew attention to the fact that Fuchs had considered them 

 the same species. Fuchs' statement, as recorded in the
