rf Exp. al. 7|-8 lin. 



Head and face ferruginous brown, the latter darker below. Eyes 

 black. Palpi : above and at the sides dull smoky brown, paler at the 

 bases and beneath, whitish at the base between. Antennae: grey 

 above, iron-grey beneath ; basal joint fulvous above, and brown 

 beneath. Thorax drab in front, and fuscous behind ; in some speci- 

 mens ferruginous. Patagia drab, with an ochreous tinge. Anterior 

 wings dull chocolate-brown at the base, brick-red at the apex, 

 divided by a pale drab undulating band between. At the base, on 

 the dorsal margin, is a conspicuous chocolate-coloured semi-ovate 

 patch ; another brick-red patch occupies the apical half of the wing at 

 the costa. These two patches are bordered with white, and divided by 

 a broad undulating band maculated with iron-grey, commencing at 

 the base of the costa, and extending nearly half its length, then 

 passes obliquely to the dorsal margin. The ocelloid patch is clearly 

 denned, grey, and bordered with white ; on its inner edge is a small 

 round reddish spot. The costa is streaked with black on its basal 

 half, and beyond the middle it is marked with four lustrous yellow 

 geminations, all directed and produced into dusky lines to a point in 

 the margin, below the apex ; the apical spot distinct, and of a deep 

 brick-red colour. Apical scales shining, with two yellow streaks 

 below the apex running through them and the cilia, then dark grey, 

 becoming paler at the anal angle ; all with white tips. Cilia below 

 the interruptions yellowish pink, then grey at the anal angle, and 

 blackish beyond. Posterior wings dull fuscous. Marginal scales 

 shining, fuscous, with luteous bases. Cilia shining, grey, with a 

 fuscous tinge. Abdomen fuscous, the caudal tuft yellow. $ Exp. al.

An uncommon species, but not variable. It is larger than 

 Anch. Lundana, though otherwise much like it ; the latter has 

 the patch on the costa beyond the middle much paler, and not 

 sharply defined on its inner edge ; whilst in A. derasana it is of the 

 same colour as the basal patch, and as clearly defined. 



The imago appears in June and July, in hedges and woods, in 

 the south of England ; it is rare in the north, but has been cap- 

 tured in Scotland. 



11. obtusana, Haw. Alis anticis runs ; fascia irregulari cinerea 

 albida cincta, a basi costae flexuosa ad angulum analem ; posticis 

 cinereo-fuscis. Exp. al. 5-51 lin.
