Prof. Westwood also remarked that. Spanus Natalicus, Westw. (ante p. 3), was 
possibly identical with Dyschiridium ebeninum, Chaudoir, although there seemed 
to be some discrepancies in the structure of the trophi. 
Prof. Westwood also exhibited larve of Endrosis fenestrella, which had been sent 
to him by a correspondent, and which were accused of having made numerous holes in 
a carpet which had been laid down new in September or October last: on taking up 
the carpet, the larve were found on or in the interstices between the boards of the 
floor, but the larva-cases did not appear to be formed of particles of the carpet. 
Mr. Stainton remarked that the only evidence against the Endrosis larve was their 
propinquity to the carpet; he had never hitherto detected that species in the com- 
mission of similar injury. 
Mr. Bond, however, bad no doubt that they would attack carpets; he himself | 
had once had a coat destroyed by them. 
Prof. Westwood said that another correspondent had called his attention to the 
injury done to the leather binding of books by Ptinus hololeucus, a well-known beetle, 
which he believed to have been imported into this country from Russia some thirty 
years ago in a cargo of leather, and which was now thoroughly naturalized. This also 
was a case of first conviction, for he had not before met with any instance of this insect 
doing actual harm.* 
Mr. S. Stevens exhibited a collection of Coleoptera and Lepidoptera from Old ,)} 
Calabar. 
Mr. 8S. Stevens also read a letter from Mr. John Young, on the subject of the 
swarms of small ants found in his house in Guildford Street; see ‘ Proceedings’ for 
October, 1863. Mr. Young stated that he had removed the pest by the use of 
Dumont’s Insect-destroying Powder, by puffing the powder into the crevices from 
which the ants issued, and laying it on the ledges, &c., on which they appeared. 
Mr. Waterhouse exhibited several portions of nests of bees, wasps and hornets, in 
illustration of the paper mentioned below. 
Papers read. 
Mr. Baly read a paper entitled “ A Catalogue of Cassidide collected by Mr, A. R. 
Wallace in the Eastern Archipelago, with Descriptions of the New Species.” 
The Secretary read the first part of a paper, by Mr. Pascoe, entitled “ Longicornia 
Malayana; or, a Descriptive Catalogue of the Species of the three Longicorn Families, 
Lamiide, Cerambycide and Prionide, collected by Mr. A. R. Wallace in the Malay 
Archipelago.” 
Mr. Waterhouse read a paper “ On the formation of the Cells of Bees,” in which 
the Author defended what may be termed the circular theory of formation, which was 
first promulgated by himself nearly thirty years previously. 
A discussion ensued, in which Mr. Bates and Prof. Westwood took part: Mr. Baly 
mentioned some observations made by himself on the formation of the nests of certain 
wasps, as corroborating Mr. Waterhouse’s view; and Mr. A. R. Wallace expressed 
his concurrence in the theory. Mr. Frederick Smith, however, was not of the same 
opinion, and promised to bring before the Society, at its next Meeting, certain facts 
which, to his mind, were conclusive against the circular theory.
