142 TORTRICINA. 



late-colour extending to the middle of the dorsal margin ; the apical 

 portion of the wing towards the costa is occupied by a large dusky 

 ferruginous -brown cloud ; this is separated from the basal patch by 

 a broad silvery-lustred band, which attains the dorsal margin, and 

 then curves upwards, and encloses an elongated brown spot at the 

 anal angle ; this band is thickly irrorated with dusky atoms through- 

 out its course. The costa is marked with geminated lustrous streaks 

 just before and beyond the middle ; those beyond are four in number, 

 produced, and converge to a point below the apical spot. Apical 

 scales (and the cilia) interrupted below the apical spot by two dusky 

 streaks running through them ; at the interruption they are white, 

 straw-colour below, with the bases dusky. Cilia straw-colour, with 

 fuscous bases. Posterior wings pale fuscous, with a pearly lustre. 

 Marginal scales fuscous, with straw-coloured bases. Cilia pale grey. 

 Abdomen shining, pale fuscous, the caudal tuft sub-ochreous. 

 $ Exp. al. 5-5^- lin. In general colour more dusky than the tf . 



The smallest British species of this genus ; tolerably constant 

 as to size, but varies in the intensity of its markings. It is a 

 common species, and was first noticed by Mr. Douglas in 1842. 

 Very like A. obtusana; but the grey colour of the underwings is 

 a distinguishing character. 



The imago appears in April and May, and again in August, 

 there being two broods in the year. It occurs in the Isle of 

 Wight and along the south of England, on the chalk ; at San- 

 derstead, StoatVnest, Riddlesdown, Mickleham, &c. 



13. siculana, Hub. Alis anticis mfo-cinereis ; stria longitudinali 

 albida, aliis brunneis fractis adnatis, macula ocellari ad angulum 

 analem cinerea ; posticis fusco-griseis. <$ Exp. al. 7-8 lin. 



Head dull chocolate-brown, palest over the eyes. Face slightly 

 paler than the head. Eyes black, with a velvety appearance. Palpi 

 fuscous above, at the sides, and beneath ; between sub-ochreous. 

 Antennae umber, paler beneath. Thorax dull chocolate -brown in 

 front, paler behind. Patagia drab, inclining to ochreous. Anterior 

 wings drab, with an ochreous tinge, marked with longitudinal bands 

 of brown and fuscous. The costa is broadly pale fuscous, and marked 

 throughout with geminated streaks, brown interspaces, the centre 

 one being broad, conspicuous, and very obliquely produced towards 

 the apical margin, as also are the streaks beyond it, these latter being 

 lustrous. Erom the middle of the base to near the apex is a broad 

 straw-coloured band ; below this is an umber streak, forked, and 

 divided beyond the middle, and extending to the apex ; the remainder 

 of the wing is suffused with pale fuscous, with a threadlike streak of 

 brown running along the median fold, the dorsal margin finely macu- 

 lated with dark brown. The ocelloid patch is grey, and has within a
