portion, followed by rich fulvous-yellow which merges in 
a broader border of a paler shade of the former colour. 
Female : fore wings brownish-yellow, darker on the 
inner half, and with a large white spot more or less bor¬ 
dered with black near the middle towards the upper 
edge, followed by a pale line which shades off into an 
intermediate colour. Hind wings fulvous-red on the 
inner portion, fulvous on the outer. 
Localities for this species, which is common, are York, 
Charmouth, Nafferton, Chichester, Plymouth, Falmouth, 
Isle of Wight, Faversham, Canterbury, Newhaven, West 
Looe, Bisterne, Barnstaple, Ipswich, Ashbourne, South- 
port, Carlisle, Arran, Dunoon, Killarney, &c. 
The perfect insect appears in July and August. 
The caterpillar is black, covered with greenish-grey 
hairs, with a white stripe along the sides, and a red spot 
surrounded with white over it on the third and fourth 
segments. 
The date of the appearance of the caterpillar is from 
September to May. 
It feeds on the oak, the whitethorn, &c. 
The male flies very fast in a headlong zigzag manner, 
and is difficult to capture on the wing. 
N.B. The hairs of the caterpillar are of a very irritant 
character and sting the hands, and these often again the 
face, if touched with them. 
Bombyx callunce. I have given a figure of the 
Moths described under this name, it being doubtful 
whether it is a distinct species, or a permanent variety 
of the preceding one.
