TORTRICINA. 317 



the base of the costa, a conspicuous spot near the middle of the wing 

 towards the dorsal margin, and a broad patch at the apex, all ferru- 

 ginous : the latter is angulated anteriorly in the middle, and encloses 

 a large round yellow spot. Apical scales ferruginous, with paler 

 bases. Cilia glossy, paler, both merging into deep ferruginous at the 

 anal angle. Posterior wings and marginal scales fuscous, the latter 

 with cream-coloured bases. Cilia glossy, whitish. Abdomen fuscous, 

 the apex pale ferruginous. Exp. al. 8-J lin. Anterior wings 

 marked as in the $ ; posterior wings darker. 



Rather uncommon ; constant in marking, but slightly variable 

 in colour. It is allied to X. hamana, but readily distinguished 

 from it by the ferruginous patch at the apex of the anterior wings, 

 enclosing a reniform spot of the ground-colour. There is one 

 variety, the X. ferrugana of Haworth, in which the wings are 

 wholly ferruginous, with the apical mark somewhat darker. 



The imago appears from May to August among tall herbage, 

 and occurs at Darenth and Coombe Woods, Charltori, Lewisham, 

 Mickleham, and other places round London ; also in Hertford, 

 Norfolk and Cambridgeshire ; at Probus in Corn wall, in Cheshire, 

 &c. ; in Scotland ; and at Kilkenny and Belfast in Ireland. 



The larva feeds in the roots of Scabiosa Columbaria. 



Genus X. DAPSILIA, HUBNER. 



Palpi as long as the head, remote, ascending. Basal joint short, 

 stout, cylindrical, truncate ; apical slender, obovate, longer than the 

 basal, horizontal ; middle ascending, moderately stout, thickest in 

 the middle, nearly three times as long as the apical. Maxilla? as 

 long as the palpi. Thorax stout, ovate. Anterior wings : length 

 exceeding twice the width. Costa slightly arcuated ; apex obtuse ; 

 apical margin rounded ; dorsal margin straight ; the costal vein 

 reaches beyond the middle of the costa ; subcostal nervures not equi- 

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

 widest before the apex, but not extending two-thirds its length. 

 Apical nervures extended. Posterior wings elongate ; apex obtuse; 

 apical margin concave ; anal angle slightly produced ; costa thickly 

 ciliated. Abdomen stoutest in the $ ; a small tuft at the apex in 

 both sexes. 



There is but one British species in this genus, which, in the 

 character of its markings, seems to locate well with the following 

 (Argyridia) ; but as the larva of the latter is unknown, we think 

 it better to retain a distinct generic name for it; there are,
