TORTRICINA. 271 



teriorly it is dilated into two acute angles, one before, the other 

 beyond the middle. Near the anal angle, on the dorsal margin, is an 

 oblique, clearly- defined, conical patch, angulated anteriorly. At the 

 apical margin, and likewise near the anal angle, is another longer 

 oblique patch, dilated at its apex, and directed towards the costa. 

 Apical spot elongated, and produced half-way down the margin. 

 On the costa are seven lustrous, silvery geminations, with chocolate- 

 brown interspaces, two before the central fascia, produced in silvery 

 streaks to the opposite margin ; those beyond the fascia are simi- 

 larly produced along the edges of the markings. Marginal scales 

 dull, chocolate-brown, with paler bases, especially below the produced 

 apical spot. Cilia slightly glossy, fawn-colour, with a black patch at 

 the apex, and before the anal angle. Posterior wings glossy, pale 

 fuscous, with a bronze hue at the apex. Marginal scales fuscous, 

 with pale ochreous bases. Cilia grey, with a fuscous tinge. Abdomen 

 iron-grey, glossy ; the caudal tuft ochreous drab. $ Exp. al. 

 6i-7 lin. 



Not a common species. 



The imago appears in June and July among mixed growth. It 

 occurs at Micldeham and various places round London; in 

 Devonshire, in the vicinity of Edinburgh and of Dublin.

Head and face dull chocolate-brown, the latter sometimes paler. 

 Eyes black. Palpi longer than the head, chocolate -brown above 

 and at the sides, paler beneath. Antennae chocolate-brown above, 

 pubescent beneath. Thorax and patagia chocolate-brown, the former 

 crested behind. Anterior wings glossy, white, with a silvery lustre, 

 much marked and fasciated with rich chocolate -brown. At the 

 base is a streaky patch, extending one -fourth along the costa and 

 one- third along the dorsal margin, and its posterior edge form- 

 ing an irregular angle, beyond the middle. Before the middle of 

 the costa commences a broad fascia, having its anterior edge slightly 

 undulate, but with its posterior border dilating widely, and ulti- 

 mately attaining the dorsal margin near the anal angle. Midway 

 between the central fascia and the apex is a second one, widest 

 on the costa, and narrowing to a point at the anal angle ; it is 

 sometimes constricted in the middle, when it slightly resembles the 

 map of North and South America; at others it is abbreviated, 

 forming only a rounded patch upon the costa, followed by a few 

 spots at irregular intervals. The apical portion of the wing has 

 commonly a reticulated appearance. The apex, as well as the edges 

 of the markings and fascia, speckled with umber ; the pale or silvery 

 portions of the wing streaked or maculated with dusky. Apical
