on the occurrence of Sphinx atropos in the same neighbourhood, 
in great quantities.” By W. Raddon, Esq.; who states that 
“ The numbers of the larvae of the Anacampsis are countless; 
not content with feeding on corn, they feed on the skirting-boards, 
joists, and rafters of the building. Mr. Spence and his son Robert, 
who w'ent with me to examine this pest, suggested that perhaps 
turpentine might destroy them ; but that idea was soon perceived 
to be useless, as on inspection of the rafters, the knots or parts 
that are the hardest, as well as containing the most turpentine, 
was the principal or favourite morsels. I brought some away, 
and placed them on a table, but they eat through the paper, and, 
as I thought, escaped ; but a day or two since I found some of 
them had eaten into the cork part of my setting boards. Can you 
suggest any thing that will destroy them, taking into your consi- 
deration that the greater part of the building has been built 
within the last two years, and that is very extensive ?” 
Mr. Waterhouse suggested that it might perhaps be found ser- 
viceable to give the wood-work of granaries attacked in the 
manner described by Mr. Raddon, a coating of pitch or tar, or to 
apply Kyan’s patent solution. 
Mr. Yarrell observed, with reference to the hybrid moths 
reared by Mr. House, that it would be desirable that an examina- 
tion of their internal structure should be made from specimens 
preserved in spirits, if any more should be obtained in the same 
manner. 
Some remarks were made by Mr. Children on the autumnal 
disease of flies, supposed by Mr. Mac Leay to be of the nature of 
a fungus, in contravention of that opinion. 
Mr. Yarrell made a communication from the Earl of Derby of 
a feather of a harpy eagle in his possession, infested with a species 
of Nirmidce, numbers of which were seen when alive running in 
and out of the quill of the feather, by a very minute hole they 
had made near its root.
