subterminal line indistinct, and the hind-wings whitish, with the hind margin and a central lunula 

 grey. Expands from \\ to if inches. A rather scarce species, found in the Alpine ranges and in 

 Silesia in July. The larva is said to resemble that of a Lciicania. 



45. A. Lateits (Hiibn.). — Fore-wings light shining grey, with the dark transverse lines double 

 and dentated, and the central shade suffused ; the elbowed line forms two curves in cell \b; the two 

 stigmata and the subterminal line are indistinct ; hind-wings brownish-grey, whitish beneath, with 

 an indistinctly darker central lunule and hind margin. Size of Griscscens. A scarce species in the 

 southern half of Central Europe in July. The larva is yellowish-brown, witl: three pale lines on 

 the back, the outer ones bordered with black above, and with an interrupted black line on the sides. 

 It feeds on grass and other low plants till May. {A. Rava, Herr.-Schaff., from Iceland and 

 Labrador, is grey, with the transverse lines much waved, and the elbowed line 8-shaped. The 

 stigmata are generally indistinct, with a darker shade between them ; the claviform stigma is often 

 scarcely visible, but terminates in a brown spot ; hind-wings unicolorous grey. It is a very 

 variable species, and is found on flowering thyme in July.) 



46. A. Nyctimena (Boisd.). — Fore-wings greyish clay-colour, darker in the marginal area, and

 unicolorous. Hind-wings whitish, with a narrow clay-coloured border. Inhabits Ardeche in 

 September. 



48. A. Cnhniuicola (Staud.). — Very close to Nyctimena, but the thorax is densely hairy and 

 crested ; the fore-wings are yellowish-grey, not darker on the hind margin ; the transverse lines 

 are distinct, the elbowed line very sharply dentated, and the under side of all the wings has an 

 indistinct central lunule and curved stripe. Size of Nyctimena. It is found in the Eastern Alps 

 in June, on the flowers of Silene Acaulis. 



*49. A. Luccmca (Linn.). — Also resembles Nyctimena, but the fore-wings are iron-grey, and 

 the hind-wings are dark grey, a little lighter towards the base. On the under side the fore-wings 

 are grey, and the hind-wings are white, all with broad blackish marginal bands. Expands from

 Central Europe in July and August. The larva is dark greenish-grey, with a double row of white
