70 TORTRICINA. 



Anterior wings : length more than twice the width ; costa in the 

 male folded to the middle and arcuated beyond ; apex obtuse ; apical 

 margin concave ; dorsal margin rounded ; the discoidal cell proceeds 

 three-fifths along the wing, the first and second subcostal nervures 

 remote. Posterior wings : apex obtuse, apical margin concave. Ab- 

 domen slender and tufted in the J , stout in the $ . 



This genus is separated from Spilonota by M. Guenee : it 

 nevertheless presents no structural differences in the imago, nor 

 do its habits vary.

Head deep fuscous, ochreous behind the eyes. Face : above same 

 colour as the head, paler below. Eyes black. Palpi yellow. Antennae 

 fuscous. Thorax and patagia deep fuscous. Anterior wings white, 

 with a deep fuscous streaky patch at the base, extending one-third 

 along the costa ; its posterior edge leaves the costal margin in nearly 

 a straight perpendicular line to near the middle of the wing, then 

 recedes, and attains the dorsal margin with a concave curve ; a paler 

 streaky fuscous cloud immediately succeeds this patch, to the middle 

 of the costa, and two others below it, paler, one in the middle of the 

 wing ; the other on the dorsal margin near the anal angle ; the 

 apical half of the costa marked alternately with small and coarse 

 spots ; a distinct eye-like mark at the apex, with a cloud extending 

 more or less down the apical margin, all fuscous ; at the anal angle 

 is a large ocellated patch, edged before and more widely behind with 

 patches of lustrous leaden-coloured scales, enclosing a white space 

 with three or four black spots or longitudinal stripes between the 

 nervures ; at the apex are one or two lustrous leaden-coloured 

 streaks. Apical scales very deep fuscous, with pale bases. Cilia 

 shining deep fuscous, becoming white (sometimes grey) at the anal 

 angle. Posterior wings pale fuscous, slightly darker at the apex. 

 Marginal scales dark fuscous, with paler bases. Cilia pale fuscous, 

 with the bases and apices whitish or straw-colour. Abdomen 

 fuscous ; the caudal tuft straw-colour or subochreous. Exp. al. 

 lin. 



This is a common insect in gardens, and also frequenting 

 hedges. It varies somewhat in size, and slightly in colour. Of 

 the size of Spilonota Roborana, and like it in general appear- 

 ance, but distinguished by the slightly smoky appearance of the 

 dark marks, and by the pale portion of the wings being less 

 speckled. 



The imago appears in July, and is generally distributed
