1872.) 171 
tubercles are six in number on each segment; the tufts on the second 
segment are composed of single dark brown hairs, but the other tufts 
are much denser, and formed of two sorts of hairs, the more numerous 
being pale brown stiff hairs, with sharp black points, and being sparsely 
barbed or feathered, the others, fewer in number, are taller, with black 
stems, and densely feathered all round with soft pale brown plumage. 
The cocoon was of an oval form, about four lines in length, formed 
of close spun silk, and attached to the cover of the box in which the 
larva was confined; the hairs of the coat were all woven in, giving the 
cocoon a brown colour, and rough texture. The pupa skin, examined 
after the exit of the moth, was about one quarter of an inch in length, 
highly polished, of a rich deep brown colour, the segmental divisions 
showing as pale reddish rings. 
Nuparta Munpana. The full-grown larva received on 31st May, 
1869, having been captured feeding on lichens on an old stone wall. 
Jts length three-eighths of an inch, its figure rather stout in pro- 
portion, uniform in bulk throughout ; the legs all well developed; six 
raised tubercles on each segment bearing long straggling fine hairs ; 
the ground colour of the back bright sulphur-yellow ; the dorsal stripe 
dark greyish-brown ; a blackish dorsal spot on the eighth segment ; the 
sub-dorsal line blackish-brown, the whole body below this, including 
the legs, of a semi-translucent pale greyish-brown, all the tubercles and 
hairs rather dark greyish-brown, the head dark brown. 
SETINA IRRORELLA. On July 30th, 1865, some eggs were received 
from Dr. Knages, and noted as globular, pearly in texture, clear 
purplish-brown in colour ; the larve hatched August 13th, but no note 
of them was taken, and they must soon have perished from want of 
proper food and treatment. However, there is no doubt that in their 
habitat they must hybernate when small, and feed up in early summer. 
On May 24th, 1867, after considerable search, a number were 
found, then approaching full growth, on the Sussex coast. he food is 
a blackish-brown lichen, growing on stones above high water mark, and 
in some cases mixed with a yellow lichen, a fact of much interest when 
the colouring of the larva is considered. The larva seems fond of sun- 
shine, moving about in it slowly over the stones; when about to moult, 
it protects itself by spinning overhead a number of silken threads, 
under cover of which it remains until the moult is completed. 
The moths were bred early in July. 
When the larva is full-grown, its length is about six-cighths of an 
inch, the figure proportionate, moderately stout, tapering a little from
