our native species, but the ground colour of the wings is a pale ashy- 

 brown, dark brown along the outer margin, a dark brown dash at the 

 anterior superior angle, a brown spot or rather a dash at the fissure, 

 and a brown dot about half-way between this and the base of the 

 wing. No one could confuse this with any known British Plume. The 

 larva of serotinus are stated by "Wallengren to feed on Galium (sp. not 

 noted) and Scabiosa arvensis. It is stated to have two broods, one 

 appearing in June and the other in September and October, and the 

 larva to be met with in May. In the south of England this species 

 has occurred to me in May and August. The M. paludicola of 

 Wallengren is thus described : — 



Anterior wings above greyish-brown, darker towards the costa, the back widely 

 bordered with ochreous. A twin brown spot at the fissure, the external border of 

 the whole costa lined very narrowly with white, with one or two indistinct brown 

 spots at the inner angle of the cilia of the anterior segment, and with a brown 

 indistinct streak at the apex of the posterior segment. 



As in Zeller's Isis, this Plume stands as PteropTiorus fuscus, var. c, 

 it must resemble that species very closely, but to none of a large and 

 varied series of fuscus in my own collection does the description apply ; 

 several are greyish-brown instead of cinnamon-brown, and many have 

 also a twin spot at the fissure, but none have the whole costa edged 

 with white. The most remarkable specimen of fuscus which has fallen 

 under my own observations was sent me from the Lake district, by the 

 kindness of Mr. Hodgkinson. Of this specimen, the following brief 

 description may not be out of place, as it certainly has quite the 

 appearance of a distinct species : — 



Size of a very large "fuscus .-" — Anterior wings cinnamon-brown, outer half 

 rather more dusky than the inner portion which has an ochreous tinge, spot at the 

 fissure replaced by a very narrow black streak beginning at the fissure and extend- 

 ing more than half-way towards the base of the wing, below this is another faint 

 black streak along the fold ; in the upper segment, parallel with the fissure near 

 the apex of the wing, is another well marked black streak, fringes dusky brown, 

 almost unicolorous, though there is rather a fainter line marking the border of the 

 wing. At the extreme apex of the superior angle of the lower segment is a minute 

 black dot. Posterior wings dusky brown, with fringes of the same colour. 



A few words more on our British Mirnceseoptili. Phcsodactylus 

 certainly does not belong to this group, nor to any of the Swedish 

 genera, but perhaps some continental entomologist has, unknown to 

 me, already characterised the genus. Its position is well indicated in
