TORTRICINA. 71 



throughout England. Common in the south of Scotland. It 

 occurs also in Ireland. 



The pupa is brown. 



The larva feeds on the Rose, Bramble, &c. ; it is of a ferru- 

 ginous colour, with a black head. 



Genus VI. SPILONOTA, STEPHENS. 



Palpi considerably longer than the head, very densely clothed with 

 long scales, especially towards the apex beneath ; basal joint short, 

 stout, drooping, truncate ; apical minute, slender, obovate, hori- 

 zontal, not so long as the basal ; middle jive times as long as the 

 apical, ascending, curved, stout, thickest beyond the middle. MaxillaB 

 longer than the palpi. Thorax moderately stout, ovate. Anterior 

 wings : length exceeding twice the width ; costal fold extending to 

 the middle; apex obtuse; apical margin concave; dorsal margin 

 slightly rounded ; the discoidal cell proceeds three-fifths along the 

 wing ; the costal vein does not extend beyond the fold ; first and 

 second subcostal nervures remote. Posterior wings : apical margin 

 concave. Abdomen slender, and tufted at the apex in the <5 > stout, 

 with the apex obtuse in the . 



The extent of this genus is much more restricted than for- 

 merly, in consequence of those species hitherto located in it, 

 but not possessing the costal fold, being transferred to Anticlea. 

 As a whole, they form a very natural group, and but few others, 

 if any, are known upon the Continent. Of the four British 

 species, those in Section A of the following table bear con- 

 siderable resemblance to each other. In repose the wings are 

 held much deflexed, but have a rounded loose aspect. 



A. Anterior wings with the basal patch more or less 

 produced or clouded along the costa Species 13 



B. Anterior wings with the basal patch distinct, and 



not produced along the costa Species 4

 basi apiceque fuscis, ad angulum analem macula ocellari magna

Head deep fuscous, ochreous over the eyes. Face same colour as 

 the head. Eyes black. Palpi deep fuscous, paler between. Antenna 

 fuscous brown above, pubescent beneath. Thorax and patagia deep 

 fuscous. Anterior wings white, shining : at the base is a deep
