128 TORTRICINA. 



assign to the present group the older Stephensian generic name 

 Steyanojjtycha. The larvse feed on shrubs and trees. 

 The three British species are thus arranged : 



A. Anterior wings with a pale fascia much dilated 



on the dorsal margin Species 1, 2 



B. Anterior wings with a pale dorsal blotch produced 



to the base along the dorsal margin Species 3 



1. naevana, Hub. Alls anticis griseis aut cinereis; basi macula, 

 fascia media irregulari obliqua cinereo-brunneis ; ad angulum 

 analem macula plumbea ; puncto nigro postico costam versus ; 

 posticis fuscis. <$ Exp. al. 6| 7 lin. 



Head fuscous. Pace drab. Eyes intense brown, with a velvety 

 appearance. Palpi long as the head, dull brown at the sides and 

 beneath. Antennae dull brown. Thorax and patagia dull brown, 

 the latter paler at the apex. Anterior wings glossy, pale drab, 

 sometimes whitish. The base is occupied by an umber patch, darkest 

 at its outer edge, streaked at the base and on the dorsal margin with 

 dark grey or leaden colour, sometimes drab ; this patch extends one- 

 fourth the length of the costa, then takes an oblique direction to the 

 fold, where it makes an angle, and proceeds to the dorsal margin, 

 sometimes in a straight line, at others it is convex. At the centre of 

 the costa commences an irregularly-bordered dark brown or umber 

 fascia, broad at its origin, narrowing at the middle (where there is a 

 conspicuous dark brown spot) and terminating within the anal angle ; 

 between this fascia and the apex the costa is dark brown, streaked 

 with drab -coloured, geminated markings. The ocelloid patch is 

 large, bordered with rich brown towards the apex of the wing, and 

 consists of two slightly lustrous, light-coloured clouds, divided trans- 

 versely by a dusky streak, bearing the longitudinal lines, which are 

 but faintly indicated, frequently almost obsolete. There is a distinct 

 eye-like spot at the apex. Apical scales drab, speckled with brown. 

 Cilia shining, iron-grey at the apex, becoming pale grey or drab at 

 the anal angle, the bases pale, and interrupted by a drab streak 

 running through them below the apical spot. Posterior wings 

 glossy, fuscous. Marginal scales fuscous, with dusky bases, but 

 paler. Cilia grey, with a fuscous tinge. Abdomen shining, fuscous 

 grey, the caudal tuft paler. 5 Exp. al. 6-1-7 lin. 



A common species, and very variable, both in the ground- 

 colour of the anterior wings, and of the markings ; the former 

 ranges from silvery white to a dark smoky grey, sometimes 

 bordering on dull brown, the latter from rich golden brown to 

 dark umber. It is very like S. geminana, and some instances of 

 PhloRodes tetraquetrana. It is rather larger than the former and 

 has its wings somewhat broader, and may be distinguished from
