238 HAUSTELLATA. — LEPIDOPTERA. 



middle, faintly resembling a prostrate Greek » , and a second behind, dentate 

 externally, and extending to the inner margin : between these streaks are 

 three or four rather conspicuous black or fuscous spots, and on the hinder 

 margin is a row of black dots ; cilia grey, with minute black dots on the 

 extreme edge : posterior wings immaculate, fuscous-ash, with paler cilia. 

 Female with abbreviated lanceolate-acute wings faintly marked as in the 

 male. 



Extremely variable in tint, arising from the absence or increased intensity and 

 number of the fuscous dots on the wings. 



Caterpillar feeds on the aspen; the pupa is very slender: the imago appears 

 towards the end of February, and is abundant throughout March in woody 

 places. 

 Very abundant in woods on the trunks of trees throughout the 



metropolitan district, and I believe in other parts of the country.

Di. Novembris. Haworth.—Steph. Catal. ii. 202. No. 7263. 



Anterior wings hoary, with an interrupted black streak extending from the 

 base to beyond the middle, and terminated by an oblique one which arises 

 on the costa behind the middle; the hinder portion of the wings is paler, 

 and bears two contiguous black dots, placed longitudinally : posterior wings 

 whitish, with the tips somewhat dusky. 



Apparently a very rare species : it has been taken on trunks in 

 November near Kennington, and also at Walthamstow, and other 

 parts of Epping Forest. 



Genus CCCXXXVIII.— Semioscopis, Hilbner. 



Palpi two, elongate, slender, recurved, subulated, nearly parallel, the base 

 densely clothed with rather long scales, having the terminal joint exposed, 

 the latter very slender and acute : maxillw short. Antennae shortish, slender, 

 pubescent nearly to the apex in the males, simple in the females ; head small, 

 with a tuft between the antennse : eyes moderate, globose : thorax slender, 

 not crested : wings decumbent during repose ; anterior elongate lanceolate, 

 pale, with dark flexuous or twisted longitudinal streaks ; posterior ample, 

 ovate-triangular, entire ; cilia all short : body rather short, attenuated at the 

 apex, and with a small tuft in the males ; somewhat robust and obtuse in 

 the females : leg-s rather short and slender. 



In my Catalogue I named this genus Epigraphia, from the letter- 

 like markings upon the anterior wings, by which character they may 

 be distinguished from the other genera of the group, — having only
