Peronca rufana, Schiff.- — The year before last, my friend, Mr. 
Dunsmore, of Paisley, when on an excursion to the west of Scotland, 
found larvae of this species in abundance, and reared the moths. 
Before the season came round he went to America, but left his friends, 
Messrs. Watson and Whyte, of Paisley, full information respecting 
his locality, and to their united kindness I am indebted for the oppor- 
tunity of rearing and describing this larva. It is so unlike the usual 
style of P eronea larvae, that I felt certain, until the moths actually 
emerged, that my kind correspondents had collected another larva 
(perhaps Penthina dimidiand) by mistake ; therefore, the emergence 
of the promised species was an agreeable surprise. The larva is not 
very active, cylindrical, plump when full grown, smoky-grey of various 
shades, sometimes blackish, especially on the back, but fading to smoky- 
green when full-grown ; spots raised and distinct, shining, and with 
short hairs. Head black, or blackish-brown, or occasionally brown, 
dorsal plate shining jet-black, anal plate yellowish-green, anterior feet 
black. In J uly and August, on Myricci gale , drawing neatly together 
the terminal leaves, and eating out the heart of the shoot. Pupa dark 
brown, spun up among dead leaves and rubbish. The moths emerged 
through September. One of them is the red variety with the slaty 
tinge, which so much resembles lipsiana , but its fore-wings are more 
pointed than in that species. 
Peronea hastiana, L. — Larva when young, very pale yellow-green, 
or bluish-green, head and plates black or blackish, or sometimes anal 
plate green; under the turned-down edge of a leaf of sallow. When 
rather older, the dorsal plate is dark brown, and sometimes the dividing 
line is visible on it. When half-grown, pale green at the sides, dusky - 
grei n on the back, sometimes with a faint whitish efflorescence or downy 
appearance, head light brown, plates green or anal plate yellow ; still 
under turned-down leaves, or beginning to unite leaves flatly together, 
and feeding between them. When full-grown, entirely pale green, 
generally with the whitish efflorescence, which is especially visible be- 
tween the segments, but the head and dorsal plate often have a brownish 
tinge. Full-grown larvae of the first brood, however, have sometimes 
black head and plates. This brood which is not common, is full-fed 
by the end of May. The second brood is plentiful enough, feeding 
between the leaves of the common species of sallow at the road sides, 
from July to September, folding the leaves or drawing together two 
or more, or joining a leaf to the twig, sometimes disfiguring the bushes, 
always leaving the feeding place when full-fed to spin up among 
rubbish on the ground. Pupa dark brown, in a slight cocoon. Moths
