TORTRICINA. . 51 



the dorsal margin ; at the middle of the costa is an open fascia, formed 

 by two prominent, undulating, oblique streaks, diverging shortly be- 

 yond their origin, and attaining the anal angle. On the costa, mid- 

 way between the central streaks and the apex, is a strongly denned 

 streak, which is more or less produced in a zigzag course to the 

 middle of the apical region, and sometimes even to the anal angle. 

 The origin of the streak at the costa suffused with brown ; and the 

 wing, beyond the basal streak, more or less reticulated, particularly 

 towards the apex. Apical scales deep ferruginous brown. Cilia 

 shining, slightly paler, and both merging into iron-grey at the anal 

 angle. Posterior wings : superior margin white, base fuscous grey 

 merging towards the apex, which is broadly pale yellow, with grey 

 markings. Marginal scales grey, with luteous bases. Cilia paler. 

 Abdomen pale fuscous, darker towards apex ; the caudal tuft pale 

 grey or dirty straw-colour. $ Exp. al. 10-12 lin. Head and face 

 unicolorous dull reddish yellow. Palpi above same colour as the head 

 and face, at the sides somewhat darker, straw-colour beneath. An- 

 tennae slender, pale brown above, and shining straw-colour beneath ; 

 basal joint clothed with pale brown above, and straw-coloured scales 

 beneath. Anterior wings marked and coloured as in the cJ ; poste- 

 rior wings, with the apex, very broadly primrose colour, and speckled 

 with grey, particularly on the superior margin. 



This species differs considerably in the intensity of the markings, 

 but is not otherwise much subject to variation. One distinct 

 variety, however, is known, and is in Mr. Edwin Shepherd's 

 cabinet, and in our own. In these, the fasciae are almost want 

 ing, being only faintly indicated on the costa. 



The imago appears from the end of June to the beginning of 

 July, and sometimes so late as the beginning of August, in 

 tolerable plenty, and is generally distributed. 



The pupa measures 5|-6 lines in length ; is of pale hazel 

 colour, clouded with chestnut on the thorax. Remains in this 

 state about fourteen days. 



The larva measures 10 lines in length ; when full-grown is 

 grass-green in colour, with a darker dorsal vessel. The head 

 is immaculate, pale green, with an olive tinge on the vertex. 

 The shield is grass-green, with two small V-like marks near the 

 base, on the vertex ; two others, crescent-shaped, near the sides ; 

 two minute dots in front at the centre, and six more towards the 

 base. The anal segment is opaque, pale green, coarsely dotted, 

 and terminated by a coronet of eight rays. It feeds on Hazel, 

 Dogwood, Ash, Wild Cherry, &c., folding the leaf longitudi- 

 nally.
