TORTRICINA. 239 



thickened beyond the middle, its lower half not so stout as the 

 basal, more than three times as long as the apical. Maxillse longer 

 than the palpi. Thorax robust, ovate. Anterior wings : length 

 greater than twice the width. Costa arcuated, apex obtuse, pro- 

 duced ; apical margin concave, dorsal margin rounded. The costal 

 vein reaches the margin before the middle, the subcostal nervures 

 not equidistant. The discoidal cell receives a nervure originating 

 near the second subcostal nervure, and passing to near the insertion 

 of the second apical nervure. The apical vein gives out five nervures, 

 of which the first is furcate shortly beyond its origin. Posterior wings : 

 apex obtuse, apical margin concave ; basal angle sometimes produced. 

 Abdomen slender, and tufted in the tf , stouter in the . 



This is synonymous with M. GueneVs genus Catoptria; this 

 latter appellation being iiow adopted to designate such part of 

 his species as have the costa folded, and are placed in the second 

 family Plicata. See ante, page 88. 



The insects comprised in this genus, although assorting well 

 with the Carpocapsida, we do not consider so natural in their 

 relations ; but this must be decided by a discrimination of the 

 larvae, which at present are but little known ; some of them are 

 known to feed in roots, and, in this respect, approach the Dicro- 

 ramphfB ; but they cannot be located there, because the perfect 

 insects have not the folded costa ; others are supposed to feed 

 in seeds, thus resembling Endopisct', some feed on herbaceous 

 plants ; and of others the larvae are altogether unknown. 



There are eight British species in this genus, which are ar- 

 ranged as in the following table : 



A. Anterior wings with the tips ochreous .... Species . 1 



B. Anterior wings with numerous streaks on the costa, 



and a small distinct ocelloid patch at the anal angle. Species 2-5 



C. Anterior wings with a large distinct ocelloid patch 

 at the anal angle. 



a. Anterior wings white or whitish, with oblique fus- 

 cous fascice Species 6-7 



a a. Anterior wings yellow, with oblique fuscous 



fascice Species . 8 



1. Alber sana, Hiib. Alis anticis brunneis, apice ochraceis; basi 

 nebulis plumbeis impositis, ante apicem striga caerulea ; costa pos-

 irroratis. <$ Exp. al. 8J lin. 



Head ochreous. Face darker. Eyes black. Palpi longer than 

 the head, above and at the sides ochreous at the base, dark grey 

 at the apex, drab beneath and between. Antennae glossy, dark fus- 

 cous. Thorax and patagia ochreous, the latter paler and glossy at
