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 homs 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 FurcillataJ, 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 Bomb^x, 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 Bombyces evolved this week, from 



cocoons produced by caterpillars, which I obtained last au- 

 tumn. The BufP-Leopard (Arctia Isabella) and the Muff
