town, about half a mile, was black with them. They did not 
cease migrating for more than a fortnight, although in much di- 
minished numbers, but for the first days the verandah appeared to 
be alive, notwithstanding the servant was ordered to sweep it three 
or four times each day. Nothing stopped them, as they climbed 
the walls and pillars equally with the shrubs ; and fortunate was it 
the vegetables did not suit their taste, otherwise nothing could 
have escaped their vast hordes. About noon every day they 
made a sudden halt, and each one reposed where he happened to 
be. They did not travel any more for the day, but at four in 
the morning they were once more in motion. They certainly 
proceeded much quicker than any caterpillars I had witnessed 
before, and might almost be said to run. On being touched they 
would immediately eject a drop of greenish fluid on the hand, the 
stain of which was difficult to wash out. I found, on keeping 
them, that they were cannibals, and made no objections to eating 
each other, making the attack on the sides. By the 12th of Ja-

“ Their pupae may be found under thistles, as well as peas and 
other garden vegetables, of a dark red colour, without any pro-

“ The moth you will see yourself ; it bore no proportion in 
number to the caterpillar, in fact, was not more plentiful than 
usual, though it is never abundant.’'

Kent, by the Attacks of the Caterpillars of one of the Geome-

to the Treasurer, accompanied by specimens of the larvae and a 
branch of a cherry-tree, the leaves of which were nearly con- 
sumed. 
“ One farmer, near Chatham, had about forty acres of orchard 
eaten up year after year for sixteen years, when the insects dis- 
appeared for a few seasons, and he had plentiful crops. Last 
year the enemy returned in force; and, as he naturally anticipates 
their continuance, he is anxious to discover some method of de- 
stroying them. The caterpillar makes its first appearance on 
the bursting of the blossom, and, as it grows, consumes both 
flower and leaf. A tree once attacked is sure to be stript, and 
when nothing green remains on it, the caterpillars descend by webs 
in long strings to the ground, and then travel to a neighbouring 
tree, which they plunder in the same manner. The gentleman
