seven specimens had been taken on the 17th of September last, at St. Leonard’s, 
feeding on the small bindweed (Convolvulus minor); also a specimen of the dark 
variety of the larva of Acherontia Atropos, found near London, and preserved by 
Mr. Baker, of Cambridge. 
Mr. F. Moore exhibited some impressions of Indian Lepidoptera taken on wax- 
paper by means of pressure applied to the original specimens, 
Mr. Francis exhibited specimens of Anthribus albinus, Zinn., taken at Folkestone 
in the second week of September last; and of Chrysomela fulgida, so arranged as to 
expose the deep red wings of that species. 
Mr. M‘Lachlan exhibited a collection of cases of the larve of various genera of 
Trichoptera, showing the different materials, and the different dispositions of those 
materials, used by the larve in forming their defences; some were composed wholly * 
of vegetable matter, others wholly of shells or small pebbles, others again bad these 
substances mixed heterogeneously; whilst one case of the genus Setodes appeared to 
be composed entirely of silk, without being covered externally with any other 
substance. 
Prof. Westwood exhibited a large sheet of whitish silky matter of extreme smooth- 
ness, resembling the finest kid, which had been sent to him by Dr. Cuthbert Colling- 
» wood, and had been taken from the bottom of a biscuit-chest; the biscuits themselves 
were found to have been attacked by larve, which were described as resembling those 
of Diptera. The Professor, however, thought it more probable that the web was the 
work of Lepidopterous larve. 
Mr. Stainton said that his first suspicion had been that the sheet in question had 
been made by the larve of Tinea granella; but the matter was more opaque than any 
he remembered to have seen, and which had been ascertained to be the workmanship 
of that species. 
Mr. Jenner Weir, however, had seen pieces even more dense and opaque, which 
had undoubtedly been done by the larve of Tinea granella feeding upon grain. 
Mr. Waterhouse exhibited two specimens of a species of Scymnus, not noticed in 
his ‘ Catalogue of British Coleoptera, and read the following notes thereon :— 
Note on Scymnus quadrilunulatus, Muls. 
“The exhibited specimens of a species of Scymnus are from Kirby’s British col- 
lection. In Kirby’s catalogue they stand as the Coccinella bis-bipustulata of Marsham 
(Ent. Brit. No. 46, p. 167), but upon comparing them with the specimen in Stephens’ 
collection, which in the ‘ Illustrations ’ is said to be the Marshamian type, I find that 
Kirby’s insect is quite distinct, it being the Seymnus quadrilunulatus of Mulsant’s 
“Coléoptéres de France’ (Sécuripalpes, p. 237, sp. 6), a species which is identified by 
several authors with the Coccinella quadrilunulata of Llliger. 
“T have re-examined the Marshamian insect, and believe that my former conclusion 
respecting it is correct, viz., that it is a four-spotted variety of S. frontalis, a variety 
which does not appear to be uncommon on the Continent, but which is apparently 
very rare in England, since no other British example has come under my notice than 
the one referred to. The statement in the ‘ Illustrations’ and in the ‘ Manual,’ that 
of the two spots on each elytron the posterior “is the largest,” is incorrect, for the ante- 
rior spot is the larger. 
“ The Scymnus from Kirby’s collection is a considerably smaller insect, being rather 
less than S. discoideus. It is of a short ovate form, with the elytra obtusely rounded
