Larva 16-legged, living in a web between drawn together 
leaves, Pupa in a firm cocoon. 
1. C. bjyerkandrella, Thub, l.c. vol. 5, p. 215. Head grey, face 
tinged with yellow. Palpi white, second joint grey on side with 
two black rings before apex, beneath with long blackish and 
white diverging bristles, terminal joint blackish. Antenne 
black, annulated with white, with moderate ciliations in the male. 
Thorax yellowish-ferruginous, with five longitudinal metallic 
erey-silvery lines. Abdomen black, with silvery-white rings. 
Legs white, tibiz with central and apical black bands, tarsi 
with four black bands. Fore-wings moderately dilated, apex and 
hind-margin rounded ; dark fuscous, basal third yellowish-ferru- 
ginous, except on margins and a central longitudinal streak ; 
two short metallic-silvery streaks from base along the costal 
margin and central streak ; two cloudy whitish transverse bands, 
first from % of costa to % of inner-margin, rather curved out- 
wards, furcate on inner-margin; second from % of costa to 
before anal angulated outwards above middle ; the space between 
these is irregularly sprinkled with whitish scales; two round 
black blotches immediately preceding second band, one on inner 
margin, the other below middle, each containing an elongate 
metallic purple-silvery mark, that in the upper one being 3- 
pointed ; several other metallic purple-silvery markings, consist- 
ing of an elongate mark on inner margin of second band above 
middle, a small costal spot between the two bands, an elongate 
mark on hind-margin below middle, preceded by an elongate 
black blotch, a spot on costa immediately beyond second band, 
and an elongate mark round apex; cilia dark grey, with a pale 
line in middle and another before tips, tips white round apex. 
Hind wings dark fuscous, blackish towards apex, with a white 
elongate spot on disc beyond middle, parallel to hind margin, 
and sometimes another less distinct white spot above it on costa: 
cilia blackish, with two white lines. Maleand female, length 4-5 
lines. | 
The species occur in Europe, S. Africa, S. America, and 
Australia. In New Zealand I met with it on the swampy thistle- 
crown plains at Hamilton, on the Waikato, in immense profusion, 
swarming on the thistle blossoms in the sunshine, in January. 
In Europe the larva feeds on /zz/a ; probably in other parts 
of the world it is not restricted from other Composite ; in New 
Zealand at least it must certainly feed on thistle.
