TORTRICINA. 283 



margin slightly rounded. The costal vein reaches the margin before 

 the middle. The discoidal cell lies towards the middle of the wing, 

 scarcely reaching two-thirds its length. The subcostal nervures 

 equidistant. An internal nervure is inserted between the first and 

 second subcostal nervures, crossing to the second apical nervure. 

 Posterior wings elongate; apex obtuse; apical margin oblique, 

 scarcely concave; anal angle somewhat produced. Abdomen mo- 

 derately robust, slightly stouter in the $ , tufted in both sexes. 



Comprising insects of moderate size and of sombre colours ; 

 the $ , at least of one of the species (fractifasciand), being much 

 smaller than the opposite sex. 



The British species in this genus are two, which are thus 

 tabulated : 



A. Anterior wings with the fasciae and markings 

 scarcely so dark on the dorsal as upon the costal 



margin Species . 1 



B. Anterior wings with the fascia and markings 



darker on the dorsal than upon the costal margin . Species . 2 



1. fractifasciana, Haw. Alis anticis favillaceis, fasciis duabus in- 

 terruptis, brunneo-fuscis : maculis costalibus geminatis obliquis ; 

 posticis griseis. <$ Exp. al. 6-6^ lin. 



Head dull brown. Face paler, inclining to ochreous. Eyes deep 

 brown. Palpi longer than the head ; fuscous above and at the 

 sides ; slightly paler beneath. Antenna fuscous, beneath pubescent, 

 the basal joint drab. Thorax and patagia fuscous, dull. Anterior 

 wings slightly glossy, greyish fuscous, with slightly darker markings 

 and fasciaB. At the base is a streaky patch, extending one-fourth 

 along the costa and one-third along the dorsal margin, its poste- 

 rior edge rounded. At the middle of the costa is an indistinct, pale 

 fascia, which attains the anal angle, narrow and darkest at its origin, 

 its anterior edge slightly undulate, its posterior dilated and angu- 

 lated about the middle. The costa, beyond the middle, is distinctly 

 geminated with white or pale drab, the interspaces umber, of which 

 one, near the apex, is twice the width of any of the rest, and is 

 sometimes produced into a pale brown streak in the direction of the 

 anal angle. The pale portions of the wing are irrorated with grey. 

 Apical scales fuscous, with the tips and bases pale grey. Cilia 

 fuscous, the tips pale grey. Posterior wings with a subdued gloss, 

 pale grey, palest at the base, and with a slight fuscous tinge towards 

 the apex. Marginal scales glossy, fuscous, the bases drab. Cilia 

 drab. . Legs fuscous. Abdomen fuscous ; the caudal tuft drab. 

 $ Exp. al. 0-6 lin. Anterior wings paler in the ground-colour and 

 darker in the markings, therefore altogether more conspicuous, than 

 in the <$ ; posterior wings wholly pale fuscous.
