14 TORTR1CINA. 



castaneous brown above and beneath, paler at sides. Antennao with 

 the basal joint and stem above, at base, eastaneous brown, merging into 

 brownish drab or whitish at the apex, the pectinations black; beneath, 

 wholly black ; sometimes the basal joint and stem above, wholly 

 drab or whitish. Thorax and patagia castaneous brown ; the latter 

 somewhat paler at the apex. Anterior wings dull sulphur-yellow 

 at the base, which is clouded with rich brown, and a grey irroration 

 on the dorsal margin. At the middle of the costa commences a 

 broad, dark brown, oblique, nearly isometric fascia ; straight, sharply- 

 defined, and reddish on its anterior edge, but suffusing posteriorly : 

 the subapical costal patch is of similar colour; along its anterior 

 border runs a streak, which is continued to the apical margin near 

 the anal angle, and the space at the apex enclosed by it is more or 

 less suffused with pinkish brown ; the interval between the pos- 

 terior edge of the central fascia and the said streak is yellowish 

 towards the costa, but clouded with pinkish brown. The apical 

 half of the wing is reticulate, the basal streaked transversely; 

 extreme margin intense brown or black. Apical scales shining, dull 

 pinkish brown, sometimes mottled with black. Cilia ferruginous, 

 in some lights rosy ; pale or whitish at the anal angle, and iron- 

 grey beyond. Posterior wings very pale grey, clothed with coarse 

 fuscous scales. Marginal scales fuscous, with pale bases. Cilia very 

 pale straw-colour. Abdomen deep fuscous; the caudal tuft pale 

 ferruginous. $ Exp. al. 6-6-J- lin. Anterior wings marked like 

 the <5 , but much narrower and more acute at the apex. 



A northern species, varying in the intensity of the ground- 

 colour of the wings and of the markings. 



The imago appears from June to August among Calluna 

 vulgaris, sometimes in great profusion ; the males flying at sun- 

 set, but the females are rarely met with on the wing. It occurs 

 on most heaths and moors in the north of England, and also in 

 Scotland. 



The larva, according to Herr Zeller, feeds, on the Continent, 

 upon Vaccinium uliginosum. 



2. prodromana, Hubner. Alis anticis canis aut griseis ; basi macula 

 nebulosa, fascia media triangulari (in qua litura oblonga grisea) 

 brunneis ; posticis cinereo-fuscis. tf Exp. al. 8 lin. 



Head black, with a few deep ferruginous scales on vertex. Face 

 obscure ferruginous. Eyes and palpi black. Antenna? : stem brown 

 at base, the remainder whitish ; the pectinations rusty black ; wholly 

 black beneath. Thorax deep rich ferruginous brown. Patagia paler. 

 Anterior wings very pale grey, inclining to white, with rich ferru- 

 ginous markings. The base, on the dorsal margin and nearly to the 

 costa, is occupied by a roundish patch. Before the middle of the costa 

 commences a broad fascia, attaining the dorsal margin on its anterior
