TORTRICINA. 221 



which the two nearest the base are produced, and attain the dorsal 

 margin, where they suffuse and become brighter, approaching a sil- 

 very lustre : the other two are also much produced, but do not 

 reach the dorsal margin ; the apical portion is of an ochreous copper- 

 colour and lustre, and bounded on its anterior border by a thick 

 silvery streak from the dorsal margin, which meets the first of the 

 three produced geminated costal streaks ; at the anal angle is another 

 thick silvery streak, but short. Apical scales smoky black, softening 

 into broad, drab bases. Cilia speckled with grey. Posterior wings 

 pale fuscous. Marginal scales pale fuscous, with yellowish bases. 

 Cilia pale fuscous grey. Abdomen grey, shining ; the caudal tuft 

 drab. $ Exp. al. 7 lin. The basal patch upon the anterior wings 

 not so distinct as in the tf , but the colours generally brighter. 



Till very recently this species was rare in cabinets. It varies 

 in size and somewhat in colour. It much resembles R. duplana, 

 but is smaller. 



The imago appears in June and July among Pinus sylvestris. 

 It was first discovered by Mr. Curtis and Mr. Dale at Bourne- 

 mouth in Hampshire, and has since been bred freely by Messrs. 

 Wm. Machiri and F. 0. Stan dish from the young shoots of that 

 tree, or of Pinus pinea. 



The larva is sluggish, and fleshy, of a turbid brown colour, in- 

 clining to red ; the head jet-black, small, shining, heart-shaped ; 

 the shield chestnut-brown, divided by a dorsal line ; the spots 

 slightly elevated, shining, and concolorous with the body. 



6. duplana, Hub. Alis anticis nitidis, basi pone medium cinereis,

 posticis basi margaritaceis, apice fusco-fuliginosis. 3 Exp. al.

Head and face ochreous. Eyes black. Palpi as long as the head, 

 ochreous. Antennae slender, dark brown. Thorax and patagia dull 

 ochreous. Anterior wings glossy; the basal portion of the wing 

 cinereous, with fuscous markings ; the apex fuscous ochre. At one- 

 third from the base is a pale fascia, streaked transversely with 

 fuscous, followed by another beyond the middle ; the interstices also 

 streaked, and slightly silvery. The costa beyond the second fascia 

 spotted with umber. Apical scales umber. Cilia umbreous, with 

 drab bases. Posterior wings pearly white at the base, merging into 

 dusky fuscous. Marginal scales same colour, with the bases drab. 

 Cilia drab. Abdomen black; the posterior edges of the segments 

 fringed with silvery-white scales. $ Exp. al. 7 lin. 



A Scotch species, and only within the last two or three years 

 added to the British list. It is rare in cabinets. Captured 

 among Fir-trees. It very much resembles R. sylvestrana, but is
