110 TORTRICINA. 



apex acute ; apical margin concave ; dorsal margin nearly straight ; 

 the costal vein not reaching beyond the fold ; the subcostal nervures 

 equidistant. Posterior wings : apex acute and somewhat produced ; 

 apical margin concave ; the submedian nervure inserted near the 

 apex of the submedian vein. Abdomen stout ; in the $ tufted at 

 the apex. 



Formerly of much greater extent, but now reduced to three 

 British species. They are all of moderate dimensions; in repose 

 they sit with the wings much deflexed, and the larvae for the 

 most part frequent fir-trees. 



The British species are thus arranged : 



A. Anterior wings with two distinct pale fascice. 



a. The pale fascia3 broad and simple Species 1 



6. The pale fascice slender and the posterior one furcate 



on the costa Species 2 



B. Anterior wings with more than two distinct pale fasciae 



or strigae, frequently interrupted Species 3 



1. finitimana, Guen. MSS. Alia anticis subargenteis, fusco strigatis ; 

 macula basi rhombea, fascia media obliqua, altera ad apicem 

 punctoque rotundato fuscis; posticis fusco-griseis. < Exp. al.

Head fuscous. Face darker. Eyes black. Palpi as long as the 

 head, whitish above ; dark drab at the sides and beneath. Antenna? 

 glossy fuscous. Thorax and patagia fuscous, the latter glossy at the 

 apex. Anterior wings glossy dirty white, with rich bronzy brown 

 markings, speckled with umber ; at the base is a streaked and 

 speckled rhomboid patch, palish at its origin, sharply denned at its 

 posterior edge, extending nearly one-third along the costa, forming 

 an angle towards the middle of the disk, and attaining the dorsal 

 margin rather more than one-third from the base. At the middle 

 of the costa commences a sharply-defined fascia, narrow at its origin 

 and gradually dilating to the opposite margin ; its anterior edge is 

 nearly straight, but there is a* sharp angle posteriorly. The apical 

 region is occupied by a broad patch, streaked with white at the anal 

 angle ; on the costa beyond the middle are two geminations, fol- 

 lowed by a simple streak, and tins latter is succeeded by a third 

 gemination, which is produced and curved, enclosing the apical 

 spot. The pale portions of the wing have a silvery appearance, more 

 or less speckled, especially on the dorsal margin. Apical scales 

 umber. Cilia paler umber, with drab bases, both becoming lighter 

 coloured towards the anal angle. Posterior wings glossy pale fuscous. 

 Marginal scales slightly paler, with the bases yellowish. Cilia 

 fuscous grey. Abdomen glossy fuscous, the apex drab. $ Exp.
