spots on the back, and a stripe on the sides powdered with pale !jrey. After the last moult 

 these markings disappear almost entirely. It feeds on Ononis spinosa, bilberry, birch, &c., from 

 autumn to May. 



*32. M. Lencophcca (W. V.). — Fore-wings pale grey, varied with brownish, with double 

 slightly-dentated transverse lines, the stigmata large, the two upper ones with a brownish 

 centre surrounded with whitish, and the claviform stigma dark ; the subtcrminal line forms a 

 distinct W, and is marked with dark arrow-heads ; and the fringes are broadly intersected 

 with brown at the ends of the nervules ; the hind-wings are pale grey, and the antennjE of the 

 male are strongly pectinated. Expands from ij to if inches. Common in Central Europe and 

 the Altai in May and June, but rare in England. The larva is pale brown, with two dark bands on 

 the back separated by a pale line, and another on the sides ; and with two black dots on each 

 segment close to the dorsal line. It feeds on grass and other low plants till April. The 

 moth and larva are figured at PI. 16, Fig. 12, a, b. 



GEXU.S XXIV. — HADENA (TR.). 



Small or moderate-sized moths, the fore-wings with the hind margin evenly curved or 

 truncated, and oblique above the hinder angle ; brown or grey, and occasionally green ; the 

 Noctua--^2i\X&xn. generally distinct, the subterminal line arched, or forming a W ; the fringes 

 more or less waved, the hind-wings slightly contracted below the tip, generally pale grey or 

 dirty white, with a broad brownish-grey border; the antenna; of the male dentated and 

 ciliated, or simple, and the abdomen extending beyond the anal angle of the hind-wings. 

 In the first two species the tips of the fore-wings are rather pointed, and in the others 

 they are truncated. The larvje resemble those of Mmncstra, and mostly feed on grasses. 

 Some prefer the roots, and others the stalks, leaves, or seeds ; and they hide themselves during 

 the day. Many larvae hybernate ; and the moths appear in summer, and may be found at 

 rest on tree-trunks or palings, or may be captured at sugar. 



* I. //. Lencostigma (Hiibn.). — Fore-wings yellowish-brown or coppery-brown, lighter in the 

 suffused submarginal band, and darker beyond, with rather indistinct transverse lines ; the sub- 

 terminal line simple and not dentated ; the orbicular and often the reniform stigma also 

 finely surrounded with white, and the former filled up with white or yellow behind ; the 

 subterminal line is paler brown, curved, but not dentated, and bordered with dark grey 

 behind ; and nervules 3 and 4 are often dusted with white at their base. In the variety 

 Fibrosa (Hiibn.) the fore-wings are more unicolorous brown, with the suffused submarginal 

 band yellowish-grey, and no distinct markings, except the yellow-spotted reniform stigma. 

 Expands about \\ inches. Inhabits Central Europe and Northern Asia in July and August. 

 The larva is white, brownish above, with black warts and a brown head. It feeds in tlie 

 lower part of the stems of Iris pscudacoriis in May and June. 



* 2. H. Satnra (W. V.). — Fore-wings dark brown, varied with dark violet-red, lighter in the 

 suff"used submarginal band, with a black basal streak in the middle, another towards the base 

 above the inner margin, and a broader one across the lower part of the central area ; the 

 transverse lines are black, double, and strongly dentated, and the stigmata are rather large, 

 and a little lighter than the ground - colour ; the subterminal line is pale and interrupted, 

 but forms a distinct W, and is spotted with black behind ; the fringes are strongly waved, 

 and the hind-wings are dark brownish-grey. Expands from \\ to 2 inches. Occurs in 

 Northern and Central Europe (except Holland and Belgium) and in the Altai in July and
