TORTRICINA. 301 



at the base, merging into umber towards the apex, which is ochreous. 

 2 Exp. al. 6-6-|- lin. Anterior wings marked as in the <$ , but more 

 suffused, particularly at the apex. 



An uncommon species ; variable in size and colour, especially 

 in the greater or less presence of ferruginous, chocolate, or rosy 

 colour. Allied to Eup. Sodaliana, but may be distinguished from 

 it by the large maculations on the costa being paler and less defined, 

 and by the blotch in the middle of the dorsal margin being mixed 

 with ferruginous brown or rosy colour. 



The imago appears in July, and occurs near Guildford, Bristol, 

 and not unfrequently near Mickleham. 



6. nana, Haw. Alis anticis basi ochraceo-albis, fascia media, altera- 

 que abbreviata ante apicem fuscis ; posticis griseis. $ Exp. al. 

 4|-6 lin. 



Head and face cream- colour. Eyes black. Palpi as long as the 

 head ; above cream-colour ; at the sides inclining to ochreous at the 

 base, and beneath. AntennaB drab. Thorax and patagia blackish, 

 mixed with grey scales, the latter with their apices drab. Anterior 

 wings dull, pale drab, inclining to cream-colour ; a pale, ochreous or 

 tawny cloud near the base and apex, with umber speckles and 

 markings. At the base is an irrorated umber patch, extending 

 broadly one-fifth along the costa. In the middle is a broad unde- 

 fined and irregular fascia, fuscous and speckled with umber, en- 

 closing a shining, streaky space on the dorsal margin, where it is 

 dilated to twice its costal width ; beyond this fascia is a slightly 

 irrorated tawny cloud, succeeded by a patch near the apex, on the 

 costa, of the same colour as the central fascia : this patch is some- 

 times produced to the anal angle. Apical scales and cilia sometimes 

 wholly cream-colour, at others alternated with iron-grey patches, 

 particularly towards the anal angle. Posterior wings with a sub- 

 dued gloss, very pale grey. Marginal scales and cilia glossy, pale 

 cream-colour or dirty-white. Abdomen iron-grey, darkest towards 

 the apex ; the caudal tuft cream-colour. $ Exp. al. 4J-6 lin. 



An abundant species ; very variable in size, and slightly so in 

 the intensity of its markings. 



The imago appears in June, July, and August, and occurs at 

 Birch, Darenth and West Wickham Woods ; various places round 

 London, and in other parts of England ; it occurs also in Scot- 

 land.
