exactly corresponds with the other, its fellow. But I once 
took a Small Copper in the month of September^ which had a 
very apparent difference in the colour of the wings ; the 
left fore-wing being much lighter on both surfaces than the 
right, though neither was defaced in any degree. It was 
resting on a stalk of grass, and was unwilling to fly, the 
weather being cold with misty rain. It was unusual to find 
a butterfly abroad in such weather. In the same month, 
one that I had taken laid nine eggs ; they were small, 
nearly round, flesh-coloured, appearing under the magnifier 
covered with indentations. 
C. — I took from an elm tree, on the leaves of which it 
was feeding, a large and handsome caterpillar, mottled with 
white and greyish green, with two spinous horns on the 
second segment, and two prominences on the fifth. It went 
into pupa on the 15 th, suspended by the tail ; the chrysalis 
has a remarkable prominence on the back. 
F. — It will continue in the pupa state about a fortnight, 
and then produce the Banded Purple Butterfly ( Limenitis 
Arthemis ). 
C. — I have also obtained a caterpillar of the Forked But- 
terfly ( Vanessa FurciUata ), and two or three of another 
kind, spinous, greenish, with a flat white back : they were 
feeding on the common nettle. 
F. — They produce the Orange Comma. (Grapta C. Al- 
bum ? J I perceive a moth, of the division Bombyx, has been 
produced from the cocoon of a yellow, hairy caterpillar, which 
I took from a poplar tree at Quebec, on the 30th of last July ; 
it spun its cocoon in a corner of a box a few days afterward, so 
that the moth has been nearly eleven months in pupa, a most 
unusual while. It is an unnamed species. 
. C. — I have had some Bomhyces evolved this week, from 
cocoons produced by caterpillars, which I obtained last au- 
tumn. The Buff- Leopard ( Arctia Isabella ) and the Muff
