our native species, but the ground colour of the wings is a pale Mh 
brown, dark brown along the outer margin, a dark brown dash at t' 
anterior superior angle, a brown spot or rather a dash at tbe fissus 
and a brown dot about half-way between this and the base off! 
wing. No one could confuse this with any known British Plume. T 
larvse of serotinus are stated by "Wallengren to feed on Galium (sp. n 
noted) and Scahiosa arvensis. It is stated to have two broods, o; 
appearing in June and the other in September and October, and t 
larva to be met with in May. In the south of England this speci 
has occurred to me in May and August. The M. paludicola 
Wallengren is thus described :— 
Anterior wings above greyish-brown, darker towards the costa, the back wid( 
bordered with ochreous. A twin brown spot at the fissure, the external border 
the whole costa lined very narrowly with white, with one or two indistinct brc 
spots at the inner angle of the cilia of the anterior segment, and with a bro' 
indistinct streak at the apex of the posterior segment. 
As in Zeller's Isis, this Plume stands as Pterophorus fuscus, var. 
it must resemble that species very closely, but to none of a large a; 
varied series of fuscus in my own collection does the description appl 
several are greyish-brown instead of cinnamon-brown, and many ha 
also a twin spot at the fissure, but none have the whole costa edg 
with white. The most remarkable specimen of fuscus which has fall 
under my own observations was sent me from the Lake district, by t 
kindness of Mr. Hodgkinson. Of this specimen, the following br 
description may not be out of place, as it certainly has quite t 
appearance of a distinct species : — 
Size of a very large "fuscus .-"—Anterior wings cinnamon-brown, outer h 
rather more dusky than the inner portion which has an ochreous tinge, spot at t 
fissure replaced by a veiy narrow black streak beginning at the fissure and extei 
ing more than half-way towards the base of the wing, below this is another fa 
black streak along the fold ; in the upper segment, parallel with the fissure n( 
the apex of the wing, is another well marked black streak, fringes dusky brov 
almost unicolorous, though there is rather a fainter line marking the border of t 
wing. At the extreme apex of the superior angle of the lower segment is a mini 
black dot. Posterior wings dusky brown, with fringes of the same colour. 
A few words more on our British Mimceseoptili. Phceodactyl 
certainly does not belong to this group, nor to any of the Swedi 
genera, but perhaps some continental entomologist has, unknown 
me, already characterised the genus. Its position is well indicated
