148 HAUSTF.LLATA. — I.EPIDOPTF.RA. 



black, and a reddish line above the legs :— it feeds on willows, and constructs 

 rather a solid foUiculus. 



Not a common species : occasionally found in Epping Forest^ 

 near Walthamstow, and at Darenth wood. I have also taken it 

 at Hertford, and received it from the New Forest, and Devonshire.

Sp. 15. flavilinea. Plate 19./ 2.—Alis anticis rufescentihus, strigd postict? 

 riifa fxtusjlavicante, punctoque basi fusco. (Exp. alar. 1 unc. 4 — 5 lin.) 



No. flavilinea. Haworth.—Ox. flavilinea.— 5'fepA. Catal. pt. ii. p. 73. No. 6143. 



Head, thorax, and anterior wings rufescent, the latter with the ordinary strigse 

 very indistinct; the stigmata rather pale yellowish, with the margin slightly 

 rufescent; towards the posterior margin is a rufescent striga, broken towards 

 the costa, as in the foregoing species, and delicately margined externally with 

 pale yellowish'; at the base of the wings is a dusky or black dot, and sometimes 

 a second, near the costa: posterior wings fuscous ; with the ciUa rufescent. 



Notwithstanding this species has been hitherto considered as peculiar to Britain, 

 I suspect from Ochsenheimer's description and reference to Engramelle, that 

 it is the true No. macilenta of Hiibner; and that the following insect, sup- 

 posed to be the species just mentioned, is the No. ferruginea of that author. 

 If it be the No. macilenta of Hiibner, the larva feeds on plantain and chick- 

 weed : the imago appears at the end of September, and I have taken it so late 

 as the beginning of December. 



Unquestionably a scarce insect near London : I have found it on 

 the paliui^s near Caen Wood, Hampstead ; and have received spe- 

 cimens from Brockenhurst in the New Forest; and from Devon- 

 shire. 



Sp. 16. macilenta. Alis anticis testaceis aut rufescentihus strigis quatuor satura^ 



tioribus, punctoque fusco basi stigmatis postici. (Exp. alar. 1 unc. 4 — 8 lin.) 

 No. macilenta. Haworth. Or. macilenta. Steph. Catal. pt. ii. p. 73. IVo. 6144. 



Head, thorax, and anterior wings testaceous or rufescent; the latter with the 

 strigae more or less obsolete, the basal one frequently wanting ; the second, 

 slightly flexuous before the stigmata, the third behind composed of indistinct 

 lunides; the fourth near the hinder margin, considerably undulated, bright 

 rufous internally, slightly flavescent or ochraceous externally : the stigmata 

 are indicated by slightly rufescent or dusky rings, and the posterior one has a 

 deep brown spot (somewhat dusted with white) at its base : posterior wings 

 fuscous, with a darker central lunule, the costa whitish ; cilia rufescent. 



There is frequently an angulated broad dusky striga between the stigmata ; and 

 the usual strigje are sometimes of a deep fuscous and very conspicuous. 



Caterpillar reddish-brown, with darker spots, with a faint whitish dorsal and 

 lateral streak: it feeds on the elm and oak: the imago appears towards the 

 end of September.
