182 TORTRICINA. 



colour occupying the apical portion, commencing before the notch 

 on the costa, and attaining the dorsal margin. 



Var. T. excavana is very like T. emargana, but has the ground- 

 colour ferruginous orange, and the dark portion of the wing is 

 paler, assuming an ashy or leaden hue. 



The imago appears from July to September, and is generally 

 distributed. It occurs in the Isle of Wight ; at Bere Wood ; near 

 Dover; Devonshire, Somersetshire, Gloucestershire; New Forest; 

 Caen Wood, near Hampstead; Coombe, Birch, and Darenth 

 Woods ; in Cheshire, Yorkshire, and the north of England ; also 

 in the vicinity of Edinburgh, at Carron, the Raehills, Dumfries- 

 shire in Scotland ; and at Belfast, in the county of Cork in Ireland. 



The pupa is stout, 4 lines in length, and ferruginous in 

 colour. The head, wing, and limb cases darker and shining, the 

 abdomen dull ; the caudal termination with a bifid hook. 



The larva, according to Fischer von Boeslerstamm, is pale 

 green, with a pale-yellow head, and affects the Sallow and Osier. 



FAMILY V. STIGMONOTIDJE. 



In this division the costa of the anterior wings is always more 

 or less regularly arcuated, never obtusely produced towards the 

 base, as in the Peroneidae, and a very frequent character is the 

 pale blotch of various size and shape in the dorsal margin. [This 

 also appears in many of the Plicata ; but there, the folded costa 

 being present, they are at once distinguished from this group.] 

 The anterior wings are of varied length, as compared with their 

 width, and in repose are held in a very deflexed position. The 

 posterior wings are ample, sometimes very broad, slightly emar- 

 ginate below the apex. 



The habits of the larva? are various, i. e. some feeding in 

 united or rolled leaves, others beneath the bark, and some in the 

 young shoots of trees. 



There are eleven genera in this family, as shown in the fol- 

 lowing table : 



A. Anterior wings with the costa nearly straight. 

 a. Palpi with the middle joint three times as 



long a*- the apical 11. HEUSIMENE.
