Mr. West, of Greenwich, exhibited a Hemipteron, Dicy- 

 phus epilohii, found on Epilobmm at Eltham. 



Mr. Moore exhibited a specimen of the second brood of 

 Cyaniris (Lyccsna) argiolus taken at Oxshott on July 12th ; 

 also specimens of Plebius (Lyccena) cegon, one of which was 

 without the marginal red markings on the upper surface, 

 and another having confluent spots on the under surface. 



Mr. Fremlin said that he had noticed a mite firmly 

 attached to the leg of a fly which was crawling on a window, 

 and asked if it was customary for Diptera to be so infested. 

 Mr. West stated that mites very largely inhabited the cracks 

 and uneven surfaces of damp and rotting wood, and that 

 their presence on the flies was simply a method of migra- 

 tion. 



Mr. R. Adkin read a report of the field meeting held at 

 Chalfont Road on July i8th (page 105). 



AUGUST lyh, 1896. 

 C. G. Barrett, Esq., F.E.S., Vice-President, in the Chair. 



Mr. S. Stevens exhibited a specimen of Papilio machaon 

 from Wicken Fen, which, besides being unusually small, 

 had the marginal black band on the hind wings very narrow, 

 and the nervures on all the wings very sparsely marked 

 with black scales. 



Mr. R. Adkin exhibited a series of Pachnobia hyperborea 

 {alpina), bred during the present summer from pupae taken 

 at Rannoch ; he was pleased to find that this species had 

 again appeared in its old habitat after an apparent absence 

 for several years. 



Mr. McArthur exhibited a preserved larva of the same 

 species on its food-plant, the crowberry [Empetruin nigrum), 

 and said that when not feeding, it lay hidden among a moss 

 which was peculiar to the mountain slopes. The pupa was 

 found at the roots either of the Empetrum or the moss. 

 Some members remarked that this moss was probably the 

 fringe-moss. 



Mr. Fremlin exhibited a short series of Phigalia pedaria 

 {pilosaria) from Saltaire, showing both the dark forms with- 

 out the reticulations and the less dark forms with the 

 reticulations. The former were very uniform in coloration, 

 and the nervures were in no way marked. 



Mr. H. Moore exhibited the photographs of two hands 

 and of a broken and self-set arm, taken by the Rontgen
