170 {January, 
for the information which led to the capture of Setina irrorella; to. | 
Mr. Barrett for eggs of Lithosia muscerda; to Mr. Birks for eggs of | 
Nudaria senex ; to Dr. White for larve of Nudaria mundana; and to 
Mr. Harwood for larvee of Lithosia mesomella and Lithosia complana. 
Nuparia sENEX. LHggs received on July 18th, 1870; larve 
hatched on 21st ; fed on decayed sallow and bramble leaves, on the 
young growth of Hypnum sericeum and Weissia cirrata, and on Lichen 
caninus ; hybernated; moulted for last time early in May, 1871; full- 
fed about beginning of June; the moth out June 28rd. Mr. Birks 
describes the locality in which the moths were captured by him, as a 
swamp very rich in plants; and he found them either hovering over 
tufts of low herbage and coarse grass, or resting on the blades and 
stems of the grass or reeds; he could see no lichens except on the 
trunks of the trees growing there, and he never noticed the moths 
haunting these, as we might suppose they sometimes would, if they 
deposited their eggs on them; possibly the food may be some lichen ~ 
growing under the herbage on the damp ground. The female, while 
laying her eggs, mixes with them fluff from a tuft at her tail, which she 
detaches by means of her two hinder feet; and the way in which the 
fine plumes from this tuft adhere to the eggs makes it rather hard to 
describe them. 
The larvz, when hatched, were placed in a flower pot with growing 
moss and lichen, and straightway hid themselves, and nothing more 
was seen of them till the solitary survivor of the whole brood was 
detected feeding early in May; probably the rest were destroyed, while 
yet tender, by the small slugs and snails that infest lichens, and cannot 
be got rid of except by picking the latter to pieces; small centipedes 
also hide themselves away craftily, and no doubt do mischief. 
The egg is small, globular in shape, but so soft that the outline is 
not at all regular, the shell shining, covered with faint irregular reticu- 
lations, yellowish in colour. The young larva is pale grey, with central 
olive stripe down the back, and with five or six long pale grey hairs 
from each tubercle. Just before the last moult, the whole larva has a 
waxen, dull, smoky appearance ; the tubercles raised, and studded with 
tufts formed of short, smoky hairs, mixed with a few feathered plumes. 
When full-grown, the length is three-eighths of an inch, the figure 
very stout in proportion; the tufts so dense that the skin cannot be 
well seen, except when the larva curls itself up, and then it is seen at 
the segmental divisions—waxen-looking, and cf a deep reddish-grey 
colour; the head shining black, the anterior legs glossy, tipped with 
black, the ventral legs translucent, in colour pale grey; the tuft-bearing
