THE CANADIAN NATURALIST. 
Puss-moths (C^rz^m);, of all ages, on the willows ; some re- 
cently hatched, with the double tail sticking out in the air 
unreasonably long; some larger, the tail much shortened, 
handsomely coloured with bright green and brown ; others of 
the same size, differing in having the back white ; they 
spin close cocoons^ abrading particles of the wood from the 
box in which they are kept^ and mixing them with the silk. 
F, — One of these produces the Griseous Moth ( Cerura 
Hastulifera ), 
C, — -A little warty caterpillar^ of a bright pellucid green^ 
feeds now on the apple tree, which spins a cocoon in an angle, 
and produces the Apple Moth (Tethea - ?J. I took, 
from a rose-bush, a handsome and singular caterpillar, black, 
with large oval spots of bright yellow down the back : from 
every segment proceeds a hair on each side, which is dilated 
at the end into a stout knob. Do you know it ? 
jP. — I have taken it likewise from the hop, but never 
succeeded in rearing it, I once took from an ash, a small 
caterpillar, black and white, with two or three knobbed 
hairs, projecting over the head ; this afterwards moulted, 
when the whole back became brown, and the clubbed hairs 
proceeded from each segment, as in this species ; I suspect 
it might have been the present, in an earlier moult. 
C. — In beating willows, a very beautiful and large cater- 
pillar, of a bright green, with circles of short bristles, pro- 
ceeding from orange-coloured tubercles, resembling that of 
the fine Emperor Moth of England, fell into my umbrella, 
but was unfortunately killed by the fall. It was no doubt 
that of Saturnia Luna* I found suspended from a stalk of 
Golden Rod ( Solidago J, one of the large spinous caterpillars 
of the Camberwell Beauty f Vanessa Antiopa ) ; it was just 
ready to become a chrysalis, which it accordingly did soon 
after, on the floor of its cell ; for I had disengaged it from its 
button of silk, from a curious desire of seeing whether it would
