7. H. Anilis (Boisd.), Albescens (Guen.). — Fore-wings rather long, pale grey, with a sharply- 

 defined black central shade, and an ill-defined subterniinal line, slightly zigzag, and bordered 

 with dusky in front ; the transverse lines are distinctly black, the inner line double, and filled

 whitish, brownish towards the hind margin. Expands about \\ inches. Described from a single 

 specimen taken in the Valais in July. 



8. H. Platinea (Tr.). — Fore-wings rather long, pale ashy-grey, shading into yellow in some 

 places ; all the markings indistinct, the intermediate spaces of the transverse lines, and the spaces 

 usually filled by the stigmata, whitish ; the subterminal line is shortly dentated, but without 

 forming a W ; hind-wings pale grey, darker towards the hind margin. Expands from if to 

 2 inches. Inhabits the mountains of South-Central Europe in July. 



9. H. Pernix (Geyer). — Resembles Platinea ; the fore-wings are broader behind, dark bluish- 

 grey, sometimes varied with yellowish, and the pattern is often as indistinct as in Platinea; the 

 reniform stigma is slightly bordered with paler behind, the transverse lines are simple and 

 dentated ; the subterminal line forms a short W, and the hind-wings are brownish-grey. The 

 variety Zcta (Tr.) is pale grey, with no yellowish shading. Expands about 2 inches. A rare

 brownish-grey. Expands from 2 to 2^ inches. Found in the Alps and Pyrenees, and in Norway. 

 It is doubtful whether this and the last species are truly distinct from the next, which is one 

 of the most variable of all known Noctnce, scarcely two specimens being alike. 



*ii. H. Exulis (Lef), Assiniilis (Doubl.). — Fore-wings varied with grey and blacky and some- 

 times with reddish, the transverse lines dentated or waved, black, or whitish, bordered with black ;

 j'ellowish-grey, with brown hind margins and ochreous fringes. Expands from li to ij inches. 

 The numberless varieties of this species have received many names, which it is not worth while 

 to enumerate here. It abounds in Iceland, and is also found in Greenland and Labrador ; it 

 is a great rarity in Scotland, though widely distributed ; it appears in July. 



12. H. Riibrirena (Tr.). — Fore-wings dark brown, varied with rusty-yellowish in the central 

 area, with simple black transverse lines, strongly dentated, and bordered with yellowish ; the
