Scotland, and Ireland in May; and Stamton records it as found only in May 

 in England. 



Larva. — In Europe, the larva feeds on the alder (Stainton's .Manual). 

 "'The caterpillar is stoul and obese; it conceals itself during the day in a 

 rolled-up leaf of the alder, in which it [\-va* exclusively by night. Its color 

 is dingy yellow, with a medio-dorsal and two lateral lines of a glaucous 

 green." — Newman's British Moths, 153.

12 8 and 6 9. — Fore wings more produced toward the apex, outer edge 

 more oblique, and the whole moth rather larger than H. trifasciata. Reddish 

 ash-gray, usually with a decided brownish tinge. Front of the head pale ash; 

 palpi long, brown, pale on the edges. Eyes black; tegulse pale ash, speckled 

 with black. Base of fore wings reddish ; an oblique, black, basal line finely 

 and acutely pointed on the median vein (sometimes the angle is wanting) 

 goes obliquely outward; it is bordered within with reddish; this, with an 

 irregular black line crossing the wing obliquely just before the discal dot and 

 bordered within with red, forms a dark band crossing the wing and enclosing 

 a median white or whitish-ash band ; a dark, irregular, black, extracliscal 

 line forming a great angle on the last subcostal venule, where it is connected 

 with an oblique, black, apical, broken line, and joining a dark patch or tuft 

 of ciliae. just beyond the middle of the inner edge; between this and the 

 median line is a clear reddish-ash area, narrow on the inner edge of the wing, 

 and three times as wide on the costa, and enclosing a linear, long, black, 

 discal dot; this extradiscal line is broadly bordered externally and internally 

 with reddish-brown, which is followed by a watery -ash band indented on the 

 venules; beyond, the wing is dark ash, the fringe concolorous ; the oblique, 

 black, apical line consists of three or four longitudinal spots. Hind wings 

 rather paler and of the same color beneath, with a single, extradiscal, dusky 

 band, sometimes wanting. Fore wings considerably darker beneath. 



Length of body, <?, 0.50-0.58, ?, 0.50; of fore wing, S, 0.55-0.70,
