As I cannot find among the numerous old descriptions of (so- 
called) species of Peronea — since deservedly reduced to the ranks of 
varieties, — any that can be relied upon as referring to this species, I 
am compelled to find it a name, and, therefore, adopt one which it has 
thoroughly earned. 
Peronea perplexana, sp. n. 
Fore-wings long, with costa much arched at the base, apex slightly pointed, and 
anal angle full and rounded, so as to give the wing a rather truncate form. Glossy, 
pale chestnut, varying to greyish-brown, and very dark grey-brown, almost black, 
appearing rather reticulated from being crossed by five irregular lines of slightly 
raised brown dots, and having in the middle of the second of these lines a distinct 
raised “ button ” of brown scales, which is very apparent in the darker varieties. 
Margin of basal blotch indicated by the usual brown streak from the base of the 
dorsal margin of the wing. Costal triangular blotch large, red-brown, vai’ying to 
black-brown, reaching two-thirds across the wing, and nearly to the apex, but often 
merged into a broad, oblique fascia, which then occupies great part of the posterior 
half of the wing. The anterior margin of this triangular blotch coincides with the 
second line of dots and raised button, already mentioned, and is of a l’ich red-brown 
in even the darkest specimens. Cilia brown, with a darker interrupted line at the 
base. Hind-wings faintly tinged with grey, with darker margin, and pale cilia. 
Head and thorax brown or grey-brown, varying with the fore-wings, abdomen 
greyish, with a light brown anal tuft. 
It differs from Schalleriana in the more decided basal arch of the 
costa, from that species and comparand in its longer wings and more 
truncate hind margin, and from logiana in its more pointed apex and 
longer wings. It is altogether a broader-winged insect, and larger 
than comariana. In colour it resembles some varieties of comariana and 
comparana , and in its produced blotch, the variety latifasciana of 
Schalleriana, but its triangular blotch is not so flat as in these species, 
and is never margined with white as in the last-named. Its larva is 
rather slender, cylindrical, not active. When young, yellowish-white, 
with a reddish or greenish internal dorsal vessel, head and dorsal plate 
black ; when older, greenish-white with green dorsal vessel, head and 
dorsal plate pale brown. On hawthorn ( Cratcegus oxyacantha) and 
blackthorn ( Prunus spinosa), folding down the edge of a leaf length- 
wise, or drawing it together, feeding in the middle of June. Pupa 
light brown. I think that the larva spins up in its leafy habitation — 
certainly it does so sometimes. The imago appears about the middle of 
July, and is almost always found in hawthorn bushes, though 1 have 
reared it from blackthorn. In this district it frequents warm, sheltered 
lanes, especially near the sea, but I have seen specimens from Hereford- 
shire, and, I think, from Kent. I do not think that it is a generally 
distributed or common species.
