Windsor forest, in tlie year 1829. It is said formerly to 
have been so abundant in the naval dockyards of Sweden, 
that Linnseus was consulted as to the best mode of stopping 
the injury done by it to the timber, an account of which he 
published in his Iter Westrogoth. 
Last year several specimens of this insect were taken in 
Dunham park by Mr. J oseph Chappell, and Mr. Sidebotham, 
on visiting the tree, found the larvae feeding in the wood. 
In July of the present year the author visited the park 
again, and found various specimens, of both sexes, in the 
tree, and also on the wing, and expressed an opinion that 
the species would be found in other places now that its 
mode of life and habits had been investigated, of which he 
gave various particulars. He also exhibited specimens of 
the insects, and of the wood bored by them. 
Mr. Sidebotham exhibited various forms of Helix insana, 
from Tenby, and distributed specimens among the members.
