Exhibitions. 



Mr. Stevens exhibited a specimen of Epischnia diversalis, a reputed British spe- 

 cies, taken in October, 1855, by Mr. Mitten, " flying in a thin wood near Hurstpier- 

 point, Sussex." 



Mr. Stevens also exhibited a few very remarkable insects sent from Borneo by Mr. 

 Wallace. Mr. White took occasion to make some remarks upon these insects, and 

 urged the members to pay more attention to exotic Entomology. 



The President exhibited a new Longicorn beetle from N. India, in which were 

 combined several anomalous characters, rendering its relationship very doubtful. 



The President also exhibited an amphipod crustacean, from a well at Wandsworth. 

 Mr. Westwood identified it as Gammarus subterraneus. Leach, belonging to the blind 

 genus Niphargus, Schiodte. Mr. Lubbock remarked that he had seen a similar ex- 

 ample from a well near Bromley, which unfortunately was not preserved. He took 

 this opportunity to mention that he would be glad to receive fresh-water Entomostraca 

 from any part of the world. 



Mr. Stainton exhibited a Lepidopterous larva, probably of an Epheslia, said to 

 have been vomited by a gentleman. 



Mr. Hudson exhibited a Dorcus parallelipipedus and a living larva of the same 

 species, dug out of an old ash tree at Coombe Hurst, Croydon. 



The Rev. W. H. Hawker sent for exhibition a singularly pale variety of Arclia 

 Caja, bred at Horndean. 



Mr. Douglas exhibited living larvaj, probably of Ocneroston)a piniariella, feeding 

 within the foliage of the Scotch fir. 



Mr. Walker exhibited a Necrophorus Vespillo and a cockchaS'er, dug up last 

 month. 



Mr. WoUaston exhibited some of the Coleoptera captured by him last summer, at 

 Madeira. 



Acari and '^'' Fogging" of Daguerreotypes. 



Mr. Tapping exhibited a drawing of an Acarus, of which many dead examples 

 were found by Mr. Fedarb, of Dover, beneath the glass of a Daguerreotype ten years 

 old ; and as this picture was affected by what is technically termed " fogging," it had 

 been thought there might be some connection between Acari and this obscuration of 

 Daguerreotype pictures, a subject which had recently excited mucli attention. 



Mr. White said this Acarus was very like, and probably identical with, Cheyletus 

 eruditus, the common paste mile; that its presence was due to paste having been
