TORTRICINA. 139 



Thorax straw-colour or drab in front, chocolate-colour behind. Pa- 

 tagia straw-colour or drab. Anterior wings glossy straw-colour, 

 with deep chocolate and ferruginous markings ; on the dorsal margin, 

 at the base, is a semi-ovate deep chocolate patch, extending be- 

 yond the middle, with its border sharply defined. From the middle 

 of the costa proceeds a very oblique fascia, truncate at the ocelloid 

 patch ; it is edged posteriorly with an angulated streak of lustrous 

 blue scales, is ferruginous-brown, with a crimson tinge, darkest 

 at its origin, and streaked longitudinally with black at the angle. 

 Beyond this fascia the wing is suffused with ferruginous, and the 

 ocelloid patch is small and but faintly indicated. The costa, at the 

 base, is distinctly streaked with fine lines ; beyond the middle are 

 five golden-lustred geminations, all directed to a point in the margin 

 below the apical spot, which is elongated, and of chocolate-colour. 

 Apical scales shining bright straw-colour, and (as well as the cilia) 

 interrupted below the apex by one black streak running through them. 

 Cilia straw-colour, becoming blackish beyond the anal angle. Poste- 

 rior wings dull, clothed with fuscous scales on a pearly ground. 

 Marginal scales fuscous, with straw-coloured bases. Cilia grey. 

 Abdomen dark fuscous, the caudal tuft drab. Exp. al. 5-6^ lin. 

 In colour not so rich as the <$ . 



A common species, variable in size, and slightly so in colour. 

 Allied to Anch. derasana and A. Myrtillana. It is smaller than 

 the former, and further separable from it by the more acute apex 

 of the anterior wings, as well as by the costal patch towards the 

 apex being paler than the basal one, and less defined on its inner 

 edge. It is also smaller than A. Myrtillana, darker coloured, and 

 has the inner margin of the basal patch rounded, and not suddenly 

 arched. 



The imago appears in May, and again in August : it must 

 therefore be double-brooded. It flies freely, as Mr. R. Shield 

 informs us, from 5 to 6^ A.M. ; it also flies at midday in the 

 sunshine. It occurs generally throughout the country ; also in 

 Scotland, in the vicinity of Edinburgh, and near Dublin. 



The larva feeds on Vicia sepium and Lathy rus pratensis, and 

 has been bred from both by Herr Schmid of Frankfort, and also 

 by Mr. Stainton. It is active, and greenish grey in colour. The 

 head testaceous, with two longish black marks on the vertex ; 

 the shield is paler than the head; diaphanous, with a large 

 black spot on each side, and two small ones at the centre of the 

 posterior margin; the spots are whitish, shining, and raised; 

 the anal segment pale testaceous, with a dark transverse line ; 

 true legs black; pro-legs same colour as the body. It spins 

 two opposite leaves of the food-plant together, and feeds on their 

 parenchyma.
