TORTRICINA. 197 



lights the costal streaks are seen to be produced into slightly lustrous 

 pale-violet markings. Apical scales umber, with paler bases, twice 

 interrupted by dull orange streaks running through them, once 

 below the apical spot, and again towards the anal angle level with 

 the dot on the margin. Cilia shining, iron-grey, with a golden lustre, 

 becoming paler at the anal angle. Posterior wings fuscous, pale at 

 the base. Marginal scales fuscous, with the bases pale ochreous. 

 Cilia dull straw-colour ; at and towards the anal angle SCANTY, and 

 short. Exp. al. 5 lin. The posterior wings rounder than in the 

 c? , and the cilia towards the anal angle neither scanty nor short. 



This is a somewhat common species, constant in size and 

 colour ; very like S. rufiliana f and till lately mixed with it in 

 our cabinets. It may, however, be distinguished by its broader 

 anterior wings, and by their apices being orange-coloured. 



The imago appears from the end of June to the beginning of 

 August, in chalky and sandy places. It occurs on the downs 

 near Croydon, and in woods in the Metropolitan district ; like- 

 wise in Norfolk, Cheshire, Devonshire, and in the New Forest. 

 It also occurs in Ireland. 



The puparium is 4 lines long, amber-coloured, and trans- 

 parent, with the segments beyond the wing-cases opaque yellow, 

 inclining to red. 



The larva is flesh-coloured, and has been bred by Mr. T. Boyd. 



6. rufiliana, Zell. Alls anticis brunneis obscuris, atro strigatis pur- 

 purascentibus ; costa strigis ochraceis ; macula ocellari punctis 

 atris ; posticis nigro-fuliginosis. $ Exp. al. 4^- lin. 

 Head dusky drab in front, dusky brown behind. Pace dusky drab 

 above, paler below. Eyes black. Palpi as long as the head, drab ; 

 somewhat paler below. Antennae above fuscous, drab beneath. 

 Thorax dusky brown, with a purplish tinge. Patagia same colour 

 as the thorax ; the apices paler. Anterior wings with a subdued 

 gloss ; rich purplish brown ; and a pale violet lustre, streaked with 

 dark umber ; very like Semasia lanthinana, with which it has been 

 confounded, but the base of the wing is much less streaky. The 

 costa is faintly streaked throughout, the apical half bearing simple 

 golden-lustred marks ; from the subapical one of which proceeds a 

 slender curved line to the anal angle, at first lustrous blue, then 

 somewhat golden. Apical margin narrowly ochreous. Apical scales 

 dark umber, or black. Cilia glossy, dark leaden colour, somewhat 

 rosy towards the anal angle. Posterior wings glossy bronzy brown. 

 Marginal scales fuscous, with drab bases. Cilia fuscous, paler at the 

 tips. Abdomen umber ; the apex fuscous. $ Exp. al. 5 lin. Head, 

 face, and palpi pale dull ochreous ; thorax and patagia fuscous ; an- 

 terior wings marked as in the < , but somewhat more dilute in 

 colour.
