212 TORTRICINA. 



Apex obtuse ; the apical and dorsal margins rounded. The discoidal 

 cell lies towards the middle of the wing, and extends scarcely two- 

 thirds its length. The costal vein reaches the margin before the 

 middle ; subcostal nervures not equidistant. Posterior wings ample; 

 apical margin very slightly concave ; dorsal margin entire ; the 

 median vein furcates before the apex, midway between the central 

 median nervure. Abdomen stout in both sexes, tufted in the J , 

 suddenly acute in the $ . 



The insects comprehended under this generic name are of 

 moderate size, and all are supposed to be Fir-tree feeders in the 

 larva state. The anterior wings of the imago are chiefly of dark, 

 sombre colours, embellished with silvery streaks and markings. 

 The larva of only one of the species (A. Strobilella) is known. 



This group consists of five British species : their order of 

 sequence is as below : 



A. Anterior wings with a narrow sharply -defined sil- 

 very-white, abbreviated streak on the dorsal margin Species 1-2 



B. Anterior wings with an obscure dilating silvery 



fascia before the middle Species 3-4 



C. Anterior wings with a distinct pale fascia before the 



middle, and the posterior wings pale at the base . Species . 5 



1. coniferana, Katz. Alis anticis nigris; strigis geminatis costali- 

 bus, altera producta dorsali, argenteis ; ad angulum analem ma- 

 cula ocellari subochracea, tribus lineolis atris ; posticis fuscis ob- 

 scuris. $ Exp. al. 5-i 6 lin. 



Head and face dark smoky-brown, the latter merging into dark 

 drab below. Eyes black. Palpi as long as the head ; dusky drab, 

 somewhat paler beneath. Antennae dull dark brown. Thorax and 

 patagia smoky umber, dull, the latter slightly glossy at the apex. 

 Anterior wings dull umber, with four cream-coloured (in some light 

 silvery) streaks ; of these the apical one is geminated, but some of 

 the others are usually simple ; the second and apical streaks are 

 produced into slightly lustrous pale violet-coloured oblique lines, the 

 latter attaining the margin below the apex, where it merges into a 

 white streak ; the first streak is obliquely and faintly produced to 

 the middle of the disk, then forming an angle, and afterwards meet- 

 ing a white blotch, more or less distinct in different specimens, which 

 sometimes has a brown streak running through it. The ocelloid 

 patch consists of one small lustrous mark at the anal angle and two 

 others above, broad, elongated, and lustrous, of a pale blue, sometimes 

 pale violet- colour ; the space enclosed is marked with longitudinal 

 black lines, with ochreous interspaces. The disk finely irrorated with 

 ochreous or grey scales. Apical scales black, speckled with ochreous. 

 Cilia glossy, dark brown. Posterior wings and marginal scales dark
