258 TORTRICINA. 



inclining to grey. Eyes intense purplish brown, with a velvety ap- 

 pearance. Palpi longer than the head, dusky drab ; paler beneath, 

 at the base. Antennae grey. Thorax tawny drab. Patagia some- 

 times paler than the thorax. Anterior wings very glossy, tawny drab, 

 inclining sometimes to brown ; towards the middle of the disk, placed 

 longitudinally, are two conspicuous brown spots, that nearest the apex 

 being the larger ; these spots are more or less developed in different 

 specimens, and are almost invariably present. Frequently the disk 

 is freckled over with smaller brown spots, particularly in the sub- 

 apical region, which is sometimes thickly studded with them. The 

 costa pale, especially towards the base. Apical scales pale grey. 

 Cilia whitish. Posterior wings glossy, pale grey, with a violet tinge. 

 Marginal scales slightly fuscous, bases paler. Cilia whitish, very 

 glossy. Abdomen shining grey ; the caudal tuft ochreous drab. $ 

 Exp. al. 9-10 lin. 



An exceedingly abundant insect, tolerably constant in size and 

 colour, but variable as to the greater or less presence of spots on 

 the anterior wings ; some specimens are nearly immaculate, in 

 others the spots are very numerous. The nearly immaculate 

 ones are the Cnephasia Cantiana of Curtis. 



The imago appears in July and August, and occurs near 

 Dover, Mickleham, Box Hill, Betchworth Hill, Sanderstead, 

 Stoat VNest, and other localities on the chalk ; also in Sussex, 

 Yorkshire, Cheshire and other places. It occurs likewise in the 

 vicinity of Edinburgh, and other places in Scotland. Also at 

 Galway in Ireland. 



FAMILY VIII. SERICORID^ES. 



More extensive than theprecedingfamily,andpresentinggreater 

 diversity of character in the imago, but scarcely less difficult 

 of arrangement; many of the species in the principal genus 

 (Sericoris), very closely resemble each other, and are, besides, 

 subject to considerable variation, especially in the ground-colour 

 of the wings. The costa is much arcuated, and in some genera 

 the length of the anterior wings is more than twice their breadth, 

 the anal angle mostly produced. In repose, these insects sit 

 with their wings in a very deflexed position. 



The larvae, so far as known (except of Orthotania) , feed in 

 united or distorted leaves ; some of them polyphagous.
