Mr. J. Cosmo Melvill exhibited two specimens of the 
Spurge Hawk Moth (Deilephila Euphorbise) ; said to have 
been captured in the larval state at Ecclesbourne, near 
Hastings, feeding in all probability on Euphorbia Amygda- 
loides, as he subsequently visited the spot and could see no 
trace of any other Spurge. 
January 17th, 1876. 
John Barrow, Esq., in the Chair. 
Mr. Sidebotham, F.R.A.S., exhibited a magnified drawing 
and specimens of lymexylon navale from Dunham Park, 
and read a short paper on the life history of the insect, 
which he and Mr. Chappell had studied since its discovery in 
Dunham Park in 1872. Previously to that time only one 
authentic British specimen was known; this was found 
at Windsor nearly fifty years ago. 
The species is very abundant in some of the old oak trees 
in Dunham Park, but specimens are difficult to capture, as 
they fly about the tops of the trees, and to obtain them 
a net attached to a very long pole is required. 
Mr. Sidebotham also read a paper on Psammodius Sulci - 
collis, and exhibited specimens taken at Southport in 1875. 
This has been considered a very rare species, but its habits 
being now known, it' is easy to obtain a comparative abund- 
ance. It buries itself in the dry sand at the foot of the 
sandhills during the day, coming out about 5 p.m. 
Mr. PLANT exhibited various objects of interest, including 
a longicorn Beetle (Astinomus sedilis) from a coal mine 
near Manchester; also cases of a N. American caddis worm 
(Phryganea sp.) much resembling a mollusk of the genus 
Yalvata, and once named by Lea Valvata arenicola.
