MOTTLED OHANGE-MOTH. 
expands from an inch and a quarter to nearly an 
inch and a half ; the upper TVings are rich yellow, 
variegated with reddish-brown, the latter colour 
enclosing several spots of a lighter yellow than the 
rest, each wing with two broad transverse bands of 
reddish-bro-wn, one near the base the other near 
the hinder margin, from which it is separated by a 
yellow band undulated on the inner side; fringe 
long and thick, the colour reddish-brown. The 
hinder nungs are dirty white, glossy, with a dusky 
crescent-shaped mark on the disk, and an obscure 
band posteriorly ; the fringe ash-brown. The thorax 
and abdomen are reddish-bromi, the former slightly 
tinged in certain places with yellow. The cater- 
pillar feeds on the pith of the common burdock 
C Arctium Lappa ), and UkewLse attacks other thick 
stemmed plants, such as Verlascum Thapsus, Scro~ 
phularia aguatiea, the spear thistle, &c. It under- 
goes its metamorphosis in the interior, where the 
pupa likewise remains till the moth is ready to 
emerge, 'which usually takes place towards the end 
of autumn. The insect is not rare in many parts 
of England, but seems to become very scarce as we 
advance northwards. The only Scotch specimen 
we have seen was taken near Rosslyn.
