TORTRICINA. 141 



paler than the thorax. Anterior wings glossy, pale drab, with deep 

 red markings. At the base is a large semicircular patch sharply 

 denned at its outer portion, tawny at the base near the costa, and 

 merging from thence into deep rich brick-red at the dorsal margin. 

 Near this patch, and commencing on the costa, is another, larger 

 and similarly- coloured, its inner edge running parallel with the 

 outer boundary of the basal one to near the dorsal margin ; it 

 then curves with a rounded bend towards the costa near the apical 

 margin, where it again assumes a downward oblique direction, 

 terminating above the anal angle ; a silvery-lustred streak or stripe 

 speckled with black divides these two patches, and follows the lower 

 edge of the posterior one to the anal angle, at which there is an 

 obscure red elongated spot, sometimes speckled with cream-colour 

 and black. The costa is spotted with black to near the middle ; 

 beyond, it is marked with four pairs of cream-coloured streaks 

 (in some lights having a silvery appearance) ; the innermost pair 

 unite, and are produced in a metallic lustred line to just below the 

 apical spot, which is very distinct. There are some longitudinal 

 black streaks in the middle of the apical region. Apical scales 

 brick-red at the apex, and iron-grey below the white streak under 

 the apical spot. Cilia : above the interruption white, with ferru- 

 ginous tips ; below iron-grey, merging rapidly into cream- col our, 

 speckled with grey at and beyond the anal angle. Posterior wings 

 deep brown, darkest at the apex. Marginal scales deep brown, 

 with cream-coloured bases. Cilia pale grey in the middle, the apices 

 and bases straw-colour. Abdomen deep brown, the caudal tuft drab.

Tolerably constant in colour, but rather variable as to size. It 

 is much like A. Mitterbacheriana and A. comptana it is smaller 

 and darker than the former, and at once distinguished by the 

 curved and hooked band across the wing ; and from the latter by the 

 obtuse apex to the anterior wings, and the darker colour of the 

 posterior ones. 



The imago appears from June to August, in the south and 

 south-west of England, and in the Midland Counties.
