distinct black dots. Beyond these dots is the second line, which 

 affords a most distinctive character to the species ; it is straight, 

 and composed of black dots running in a direction oblique to the 

 hind margin. The hind margin is more or less distinctly dotted. 

 Cilia grey, with a faint fuscous tint. Hind wings shining grey." 

 — (Vaughan.) 



This species is closely allied to H. nebulella, and also to H. 

 bincevella ; some entomologists, in fact, have considered it to be 

 a var. of the last named. It is, however, separated from both its 

 nearest allies by its smaller size, and maybe at once distinguished 

 by the straight, oblique, dotted submarginal line. 



Larva. — " Deep purplish brown ; ventral surface slightly 

 tinged with olive ; head, and plate on second segment, deep 

 blackish brown and brilliantly polished ; the rest of the body 

 rather shining, with a faint violet gloss." — (Buckler, abridged.) 



Introduced by Mr. Vaughan, November, 1870. 



British Localities. — Stapleton; Norwich; Dover; Folke- 

 stone; Southend; Chattenden (Leech). 



Distribution. — Central and Western* Germany ; England. 



Note. — The earliest specimens noted in this country were 

 captured in Essex some time during the month of May, 1870. 

 In June of the same year larvte were found feeding in the stems 

 of ragwort.

 Expanse, 7 — 8 lines. " Fore wings very narrow at the base, 

 strongly arched beyond the middle. Costal lappet narrow, with 

 a tuft of long hair-like scales laid lengthwise beneath the wing. 

 Fore wings smooth and shining, pale slate-colour, with a small 

 ill-defined ochreous patch at the base of the dorsal margin. The 

 first transverse line is at one-third the length of the wing from 

 the base, pale gre}', externally edged with dark grey spots, and 

 nearly perpendicular to the margins. Second line pale grey, often 

 obsolete, oblique, angulated above the middle, slightly edged on 

 both sides with giey dots. Faint dashes of ochreous lie longi- 

 tudinally between the wing-rays. Hind wings whitish, edged 

 with brownish, cilia white. $ with one ochreous tuft at the base.
