from whom Dr. Richardson received the insects and this informa- 
tion had cut off great numbers at this period, by surrounding the 
stems with quick-lime, which destroys them the instant they 
touch it : but the lime does not continue active above a day or 
two, nor after a shower of rain. A tree which has been attacked 
pushes out a second series of leaves after the insects are gone, 
wdiich preserves its life, but no blossom appears the second time. 
One year the leaves of some of the trees were eaten a second 
time, and these trees died. Cherry-trees, apples and gooseberries 
are attacked, but whether one or more kinds of caterpillars are 
concerned in these ravages he had not ascertained. When recent 
the caterpillars are of a deep green. 
“ I will have a few' of the caterpillars collected and put into a 
box with earth, to undergo their metamorphosis.” 
In the discussion which ensued, Mr. Sells and several other 
members entered into various speculations as to the manner in 
which the vast number of larvae described by Mr. Jenyns had 
from time to time originated, considering it most probable that 
they had not been introduced into the stomach at once, but at 
various periods. The Secretary objected to the description of 
the mode of respiration both by tracheae and branchiae, supposed 
by Mr. Jenyns to be possessed by these larvae, considering it 
doubtful whether the lateral appendages of the body possessed 
any respiratory branchial functions as described by Mr. Jenyns. 
The Honorary President returned thanks to the Society for the 
vote of thanks which had been forwarded to him for his collection 
of insects.
