134 TORTRICINA. 



It feeds within the chamber on the inner portion of the leaf, 

 leaving the venation and outer cuticle untouched ; it goes from 

 one leaf to another performing the same process. When about 

 to assume the pupa state, it spins a kind of covered way from 

 the top of the chamber to the bottom, where it forms a loose 

 cocoon; it lies dormant during -the winter, and goes into pupa 

 in the spring. When the imago is about to emerge, the pupa 

 wriggles its way to the top of the chamber, and effects its 

 change. 



3. Upupana, Treit. Alis anticis nigris fuliginosis ; apice costse 

 geminatis strigatis, pone medium ferruginea ; posticis nigris fuli- 

 ginosis dilutioribus. <J Exp. al. 7-| 8 lin. 



Head ochreous behind and over the eyes ; dull brown in front. 

 Face dull ochreous above, paler below. Eyes black. Palpi above, at 

 the sides, and between ochreous, with the tips dusky, paler beneath. 

 Antennae dark fuscous, at the base ochreous. Thorax dusky ochreous, 

 paler in front. Patagia rich ochreous, slightly paler at the shoulder. 

 Anterior wings : dull intense smoky brown to the apical angle, 

 where it softens into rich ferruginous ; at the base, and especially 

 on the costa, is an obscure leaden gloss. The costa is marked before 

 and beyond the middle with geminated streaks ; those before the 

 middle are of a leaden lustre, those beyond shining, cream-colour, 

 and are directed to a point below the apical spot, which is distinct, 

 and of intense brown. A streak of lustrous blue scales lies within, 

 and parallel to, the apical margin. In some lights the markings, as in 

 Anch. Lundana and A. derasana, are distinctly visible. Apical scales : 

 below the apex intense brown, with yellow bases, the rest ochreous, 

 mottled with brown. Cilia slightly shining ; at the apex intense 

 brown, followed by two cream-coloured streaks, and then they merge 

 into a pinkish-drab colour, slightly paler at, and iron-grey beyond, 

 the anal angle. Posterior wings deep purplish brown, with a smoky 

 appearance, darkest towards the apex. Marginal scales fulvous, 

 towards the anal angle speckled with dark fuscous. Cilia slightly 

 paler. Abdomen deep brown. $ Exp. al. 8-8 lin. 



First introduced into the British list by Mr. H.Doubleday, who 

 bred it in 1848. It does not vary in colouring, but differs slightly 

 in size. The dark brown colour, both of the anterior and posterior 

 wings, distinguishes it at once from all the other British species 

 of this genus. 



The imago appears in May and June at Black Park, Darenth, 

 and West Wickham Woods; also at Epping, near Hastings, 

 and near Tunbridge Wells, among Oaks and Birches. 



The larva feeds on Oak.
