TORTRICINA. 29 



with its posterior edge gently undulated and produced outwardly 

 towards the anal angle. The basal patch is distinct, angulated in 

 the middle, proceeds rather farther on the dorsal margin than 

 on the costa, and is composed of grey, fuscous, and rich and intense 

 brown patches and streaks. The central fascia is chiefly of golden 

 (sometimes subochreous) brown, with obscure markings, especially 

 in the middle, and mixed with iron-grey patches exteriorly. The 

 space between the basal patch and the fascia is broadly pink at the 

 costa, followed by a cloud of iron-grey colour spotted with brown, 

 terminating by another cloud of similar colours on the dorsal margin. 

 There is a distinct intense brown spot, of variable shape and size in 

 different specimens, near the middle of the posterior edge of the 

 central fascia. From the apical margin originate several irregular 

 long streaks, frequently curved, of a pale brown or subochreous tint. 

 Apical scales pale brown, with pinkish bases. Cilia dark brown, 

 mottled with a paler shade ; the bases subochreous, and both be- 

 coming dusky pink at the anal angle. Posterior wings clothed with 

 coarse fuscous scales on a whitish or straw- coloured ground. Mar- 

 ginal scales fuscous, with straw-coloured bases. Cilia pale straw- 

 colour. Abdomen fuscous, the caudal tuft with an ochreous tinge. 

 $ Exp. al. 7-7-J lin. Apex of the abdomen ochreous. 



This pretty and distinct species varies in the intensity of its 

 colouring, and is of the size of A. Pruniana. It was first cap- 

 tured by the late Richard Weaver, in Inverary, in 1844; and 

 Mr. Stainton, who has since met with it in the glens of the Isle 

 of Arran, thinks it frequents the Mountain Sallow. 



This species seems confined to the north of England and to 

 Scotland. It appears in June, frequenting the mosses and 

 damp places on the hills. 



The larva feeds on the Sweet Gale (Myrica Gale).

 apicali fusco ; in medio marginis fasciae punctum, tribusque margine 

 apicali atris ; posticis marls basi albicantibus, apice fuscis ; fee-

Head dark fuscous, paler behind. Face paler than the head. 

 Eyes black. Palpi above fuscous, darkest at the apex, at sides paler; 

 whitish beneath and between. Antenna pale fuscous. Thorax 

 brown. Patagia drab at base and apex, fuscous below the shoulder. 

 Anterior wings dull, rich cream-colour ; the basal cloud extends 

 two -thirds along the costa and nearly to the anal angle on the dorsal 

 margin. At the base is a pale brown patch, streaked with rich 

 chocolate-brown. From the middle of the costa proceeds a broad, 

 irregular, much-angulated fascia of rich brown colour, shaded with 

 chocolate, umber and black ; the space between this fascia and the
