TORTRICINA. 59 



base and apex ; posterior wings of a pale brownish hue. Abdomen 

 pale fuscous ; the apex acute, and slightly ochreous. 



A very conspicuous species, varying considerably in the extent 

 and colour of the markings, and somewhat also in size; allied to 

 L. semialbana and L. latiorana, but distinguished from either 

 by the glossiness of the anterior and posterior wings. 



The imago appears in June and July, commonly in moist, 

 marshy places, flying at sunset. 



The larva is polyphagous, but attached chiefly to low herbage. 

 It has been found feeding on Epilobium hirsutum, Anudum 

 phragmites, Cochlearia armoracea, Comarum palustre, on various 

 grasses, &c. It is dull, dark brown, with a black shining head, 

 very active, and wriggles violently on the slightest disturbance. 



6. unifasciana, Dup. Alis anticis testaceo -run's ; fascia media ob- 

 liqua maculaque postica dorsali sattiratioribus, obsoletis ; posticis 

 griseis. 3 Exp. al. 6| 1\ lin. 



Head testaceous yellow, with a reddish tinge. Face slightly 

 darker than the head. Eyes somewhat shining, black. Palpi as 

 long as the head, and of the same colour throughout. Antennae 

 pale brown above, still paler beneath. Thorax and patagia same 

 colour as the head. Anterior wings dull ochreous, with a slight 

 reddish tinge, with pale reddish brown markings, and the apex reti- 

 culated with some dusky markings on the dorsal margin ; the base is 

 occupied by a broad, very obliquely bordered patch, slightly darker 

 than the ground-colour of the wing, and terminating on the dorsal 

 margin in a dusky spot ; at the centre of the costa commences a 

 slender, oblique, faintly denned fascia, most apparent at the costa 

 and at the anal angle, within which is another dusky patch ; on the 

 costa near the apex is a semilunate brown spot. Apical scales 

 shining yellow. Cilia paler, merging into grey at the anal angle. 

 Posterior wings pale grey. Marginal scales shining, pale fuscous, 

 with luteous bases. Cilia shining pale grey. Abdomen fuscous, 

 darkest towards apex ; the caudal tuft shining, and with a leaden 

 tinge. $ Exp. al. 7-8 lin. Anterior wings of a redder hue, paler at 

 the base, and without the markings as in the $ . Abdomen with 

 the caudal tuft small and luteous. 



The smallest British species of this genus : it varies consider- 

 ably in size, and somewhat in colour. 



The imago appears abundantly among Privet in June and 

 July, of which shrub the larva spins the leaves of the young 

 shoots together, assuming the pupa state therein.
