THE CANADIAN NATURALIST. 



Puss-moths (Cerura), 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 ?). 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 ? 



F. 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 j 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), one of the large spinous caterpillars 

 of the Camberwell Beauty (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
