274 TORTRICINA. 



breous fascia, clearly defined on its anterior edge, but suffusing poste- 

 riorly into the clouded apical portion. Above the anal angle, and 

 originating on the apical margin, is a well-defined umbreous streak 

 or fascia, which does not reach to the costa. Before the middle are 

 two geminations, which are produced in streaks to the dorsal margin ; 

 beyond are three others, ochreous, more or less distinct. Towards the 

 apex are a few leaden-coloured clouds. Apical scales black, with 

 ochreous bases. Cilia ochreous, with a few black scales in the 

 middle. Posterior wings and marginal scales smoky black; the 

 bases of the latter dull drab. Cilia cinereous. 5 Exp. al. 6-frJ lin. 

 In colours richer than the tf , and with the yellow space beyond the 

 basal patch much brighter. Posterior wings with the cilia grey. 



An uncommon species; allied to S. Euphorbiana, which it 

 very much resembles, but is distinguished from it by the rounded 

 posterior edge of the basal patch. 



The imago appears in July and August, frequenting Oaks, &c. 

 It occurs at Darenth Wood ; near Tunbridge Wells, near Ripley, 

 near Guildford ; at Riddlesdown, at Blandford, in Dorsetshire ; 

 in the New Forest, and in Worcestershire. 



12. bifasciana, Haw. Alls anticis pallide griseis vel albidis ; basi 

 fascia, medio altera cinereis fusco-strigatis ; apice puncto fimbria- 

 que fuliginosis ; ante apicem nebula pallida ochracea ; posticis 

 fuscis. <5 Exp. al. 6^- lin. 



Head drab on the vertex, dull grey at the sides. Eace drab. Eyes 

 black. Palpi as long as the head, dull drab. Antenna? dull brown : 

 basal joint clothed with drab scales. Thorax and patagia drab, with 

 transverse bands of dusky scales. Anterior wings pale drab, with a 

 yellowish tinge, and dark fuscous-grey markings. At the base is a 

 patch extending one-fifth along the costa, and one-fourth along the 

 dorsal margin ; its posterior edge oblique, slightly and broadly 

 convex in the middle. The central fascia is very broad, being equal 

 nearly to one-third the length of the wing, having both its edges 

 parallel with the posterior edge of the basal patch ; posteriorly this 

 fascia is slightly angulated, and not sharply defined. In the apical 

 region is a roundish olivaceous drab, or pale ochreous cloud. The 

 costa is marked with six geminations, two before, one on, and three 

 beyond, the central fascia. The apical spot distinct, and a few dusky 

 spots along the apical margin. Apical scales glossy, umber. Cilia 

 iron-grey, paler towards the anal angle. Posterior wings dull, pale 

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

 grey. Abdomen fuscous grey, with a large dull straw-coloured tuft 

 at the apex. $ Exp. al. 6^ lin. Anterior wings with the markings 

 more defined than in the $ . 



Somewhat rare in cabinets; tolerably constant in size and 

 colour.
