the pupae existing in them between the cuticles be destroyed, 

 which would account for the comparative rarity of the perfect 

 insect. 



Mr. S. Stevens exhibited a living specimen of Lamia textor, 

 found by Mr. Barton in an osier bed, near Bristol, and fed for 

 two months on osier leaves. 



Mr. W. W. Saunders exhibited some tobacco, imported in 

 bales from South America, which had been fed upon by the larvae 

 of Lasioderma testaceum, Steph. He observed that only the thin 

 portions of the leaf were eaten, and that the amount of damage 

 done to the tobacco was considerable. It was noticed that the 

 destructive qualities of this Lasioderma to capsicum and shumac 

 had been exhibited to the Society in 1847, and that the species 

 had a wide range of food. 



Mr. Shepherd exhibited a long series of Peronea tristana, Hiib., 

 bred from larvae found on Viburnum Lantana. This species has 

 been known in our collections under the names of trigonana, 

 plumbosana, Boscana and Logiana, all of which it was now shown 

 were but varieties of one species. It was also interesting to find 

 that there was not among them any of the varieties of ferrugana, 

 W. V. (gnotiiana, Haw.), which is considered on the Continent to 

 be synonymous with tristana, Hiib. 



Captain Parry exhibited a box of splendid insects from Cay- 

 enne. 



Mr. Douglas exhibited a fine Deilephila Celerio, found by a 

 child in a garden at Folkestone, on 23rd October ; also several 

 Tineidce, beaten out of thatch in the neighbourhood of Folkestone: 

 the most worthy of note were Gelechia vilella, Depressaria rolun- 

 della, D. depressana, Fab. (Blunlii, Curtis), D. ultimella and siib- 

 propinquella. 



Mr. Westwood exhibited, from the collection of Mr. Melly, 

 some small Coleoptera from Melbourne, South Australia, including 

 ten species of Pselaphidce, one of which appeared to be of the 

 genus Articerus of Dalman, said by that author to have been found 

 in amber, and remarkable for having only one joint to the an- 

 tennae : the present specimens were found in the centre of nests of 

 black ants, three to six at a time, but not frequently occurring. 

 Mr. Westwood also exhibited, from Mr. Melly 's collection, two 

 Goliath beetles from Tropical America : they were two distinct 

 species of the genus Dicranorhina, closely resembling each other, 

 and hitherto confounded under the name of G. micans, Drury. 

 He read the following description of each :
