TORTRICINA. 63 



with shining yellow or drab scales. Apical scales shining, yellowish. 

 Cilia shining, greyish at apex, becoming drab at the anal angle, and 

 iron-grey beyond. Posterior wings fuscous, edged with yellow at 

 the apex. Marginal scales shining, dark grey, at the anal angle 

 fuscous with luteous bases. Cilia dark grey at the anal angle, paler 

 at the apex. Abdomen and caudal tuft fuscous, the latter yellow 

 beneath. $ Exp. al. 9-11 lin. Anterior wings marked as the tf , 

 but with the anterior edge of the central fascia more distinctly un- 

 dulate. Posterior wings sometimes broadly suifused with yellow at 

 the apex. Abdomen fuscous, acute at the apex. 



A common species, varying somewhat in size, and much as to 

 the colour and intensity of the markings, ranging from pale 

 hazel to umber. The paler instances represent the Tortrix 

 obliquana of Haw., and are of very rare occurrence. It most 

 resembles T. Roborana, but is smaller, and may readily be 

 distinguished from that species by the pale lustrous edging to 

 the markings. 



The imago appears in July, is common in the metropolitan 

 district, and generally distributed. 



Pupa 5 lines long, dark chestnut-brown above, paler beneath, 

 with short isolated hairs sparingly disposed over the surface. 

 This state endures from one to three weeks. 



Larva full-grown about the end of May, measures from 10 to 

 12 lines in length, is active, of a dull olive- or sea-green colour ; 

 the spots white with black centres. The head is shining jet 

 black. The shield has its anterior margin dead white, then 

 softening into brown in the middle, and to black at the base. 

 The anal segment with a conspicuous oval corrugated black plate. 

 It feeds on Oak, Honeysuckle, Beech, Poplar, Sloe, Sycamore, 

 Maple, Whitethorn, Ash, &c.

 al. 7-8-1- lin. 



Head and face dull fuscous, with an ochreous tinge. Eyes intense 

 purplish-brown, with a velvety appearance. Palpi as long as the head, 

 fuscous above, slightly ferruginous at the sides and beneath. Antennas 

 same colour as the head ; the basal joiut clothed with pale shining 

 scales. Thorax and patagia dull fuscous. Anterior wings shining 

 fuscous, in some specimens with a purplish flush, particularly in the 

 middle ; near the base is an abbreviated brown streak, curved out- 

 wardly, and dilated considerably towards the dorsal margin ; the 

 central fascia also brown, narrow on the costa, dilating widely in its
