Peronea rufana, Schinv — 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 Peronea larvae, that I felt certain, until the moths actually 

 emerged, that my kind correspondents had collected another larva 

 (perhaps Penthina dimidiana) 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 July and August, on Myrica 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 lijjsiajia, 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- 

 green 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
