296 TORTRICINA. 



pearly-lustred ground. Marginal scales fuscous, with straw-coloured 

 bases. Cilia shining, pale grey. Ahdomen pale fuscous, the caudal 

 tuft straw-colour. $ Exp. al. 8-8J lin. 



This lovely insect varies considerably in size, as well as in tbe 

 intensity of its markings, which become paler after death, espe- 

 cially in old specimens. The Tortrix albana of Haworth is but 

 a pale variety of this insect. 



The imago appears rather plentifully, in some places, among 

 Ragwort, flying at dusk. We once took it in considerable numbers 

 among Inula dysenterica. It occurs throughout the Metropolitan 

 district in July; at Tunbridge Wells ; in Worcestershire, Cheshire, 

 &c. ; also in Scotland ; and at Carlow in Ireland. 



The larva is said to feed on the Common Ragwort (Senecio 

 Jacobaa) ; most probably it lives in the root. 



Genus VII. EUPGECILIA, STEPHENS. 



Palpi slightly longer than the head; basal joint stout, short, trun- 

 cate ; apical obovate, slender, as long as the basal ; middle stout, 

 thickened beyond the centre, ascending, three times as long as the 

 apical. MaxillaB as long as the palpi. Thorax stout, ovate. An- 

 terior wings elongate, triangular ; length equal to twice the width ; 

 costa nearly straight, or very slightly arcuated ; apex obtuse ; apical 

 margin more or less rounded; dorsal margin straight; cilia pro- 

 duced at the anal angle. The costal vein reaches to the middle of the 

 margin. The subcostal nervures equidistant. The discoidal cell 

 capacious, much widest towards the apex, not reaching two-thirds 

 along the wing. The apical nervures extended. Posterior wings 

 elongate ; apex obtuse ; apical margin very concave; basal angle 

 diminished. Abdomen moderate, stoutest in the $ , a small tuft at the 

 apex in the 3 . 



A very numerous genus, and the species contained in it are of 

 small and moderate size ; none attaining large dimensions, and 

 are, as a body, liable to a considerable range in colour. But few 

 of the larvae are known ; probably they feed chiefly on the seeds 

 of herbaceous plants. 



There are nineteen British species, which are arranged as in 

 the following table : 



A. Anterior wings with the central fascia inter- 

 rupted, and not denned in shape. 

 . Posterior wings in the <$ nearly wholly white, 



fuscous grey in the $ Species . 1 



b. Posterior wings fuscous in both sexes . . . Species . 2-3
