SCIENTIFIC SOCIETIES. 



Entomological Society of London. 



August 3, 1887. — Dr. D. Sharp, President, in the chair. 



Mr. John Witheriugton Peers, M.A., of Wendover, near Tring; and 

 Mr. R. G. Lynam, of the North Staffordshire Infirmary, Stoke-on-Trent, 

 were elected Fellows of the Society. 



Jonkeer May, the Dutch Cousul-General, exhibited a pupa and two 

 images of Cecidomyia destructor (Hessian Fly), which had been submitted 

 to him for exhibition by the Agricultural Department. 



Mr. W. White exhibited, and made remarks on, a specimen o( Philam- 

 pelus satelUtia, Linn., from Florida, with supposed fungoid excrescences 

 from the eyes. Mr. Stainton said he was of opinion that the supposed 

 fungoid growth might be the pollinia of an Orchis. Mr. Poulton expressed 

 a similar opinion, and the discussion was continued by Mr. Pascoe, 

 Dr. Sharp, and others. 



Mr. White also exhibited a specimen of Catephia alchipnista, bred from 

 a pupa collected by Mr. Ralfe last autumn on the South Coast. 



Mr. M'Lachlan sent for exhibition a number cf oak-leaves infested by 

 Phylloxera punctata, Lichtensteiu, which he had received from Dr. Maxwell 

 Masters, F.R.S. 



Mr. Champion exhibited two rare species of Curculionidm from the Isle 

 of Wight — viz., one specimen of Baridius analis, and a series of Cathor- 

 viiocerus socius. He remarked that C. marUimus, Rye, had been placed in 

 recent European Catalogues as a synonym of the last-named species, but 

 that this was an error. He also exhibited a series of Cicindela germanica, 

 from Blackgang, Isle of Wight. 



Mons. Alfred Wailly exhibited, and made remarks on, a number of 

 living larvae of Anther cea pernyi, A.mylitta, Telea polyphemus, Platysamia 

 cecropia, Actios luna, Attacus cynthia, Callosamia promethea, and other silk- 

 producing species. He also exhibited imagos of the above species, imagos 

 oi Anther aa Yama-mai, and a number of species of Diurni from Sarawak. 



Mr. Poulton exhibited crystals of formate of lead obtained by collecting 

 the secretion of the larva of Dicranura vinula on 283 occasions. The 

 secretion had been mixed with distilled water in which oxide of lead 

 was suspended. The latter dissolved, and the acid of the secretion being 

 in excess the normal formate was produced. Prof. Meldola promised to 

 subject the crystals to combustion, so that their constitution would be 

 proved by the final test. 



Mr. Oliver Janson called attention to Mr. Pryer's new work, ' Rhopa- 

 locera Niponioa,' and to the fact that the illustrations had been executed 

 by Japanese artists. — H. Goss, Hon. Secretary.
