54 HAUSTELLATA. — LEPIDOPTERA. 



Head fuscous: thorax griseous, fuscous anteriorly: anterior wings purplish, 

 darkest at the base, which has an obscure geminated dusky striga ; towards 

 the middle of the wing is a second deep black, slightly bent, geminated 

 striga, preceded by a somewhat obscure dusky one ; and behind the middle is 

 a third, also of a deep black, and considerably curved; between these strigse is 

 an irregular yellow spot, bearing three fuscous clouds, and forming the figure 

 80 ; between the third striga and the hinder margin is a single curved fuscous 

 striga, followed by a waved pale one, reaching from the costa to the anal angle; 

 and at the apex is an oblique slightly curved black streak ; on the hinder 

 margin is an interrupted black line ; the ciha are cinereous, with the apex 

 darkest: posterior wings whitish-ash, with an obscure fascia behind the 

 middle, and the hinder margin fuscescent. 



Caterpillar yellow, with black lateral dots, and three large spots anteriorly, the 

 head brown :— it feeds on the poplar : — the imago is produced at the end of 

 May or beginning of June. 



Of this remarkably distinct species, I have hitherto seen but two 

 examples ; one in my own cabinet, captured near Birmingham ; the 

 other taken in the larva state last season, by my friend the Rev. F. 

 W. Hope, at Netley in Salop, and reared by him, 30th May last, 

 and shown to me alive. It has been taken near Bristol. 



C. With the anterior wings elongate, rather narrow, obtuse : the posterior ab- 

 breviated, small : body short, robust, pilose or woolly : palpi very hairy at the 

 base, the last joint considerably elongated and exposed.

Head cinereous, mixed with black ; thorax very pilose, cinereous, with black 

 irrorations, and frequently two distinct streaks of the latter colour towards the 

 anterior margin : anterior wings cinereous, tinged with greenish or yellowish 

 towards the costa, with a geminated, oblique, subundulated deep black striga 

 before the middle ; a second, somewhat angulated in the centre, behind the 

 middle, and a single undulated one near the hinder margin, reaching from 

 the apex of the wing to the anal angle ; the hinder margin itself with a faint 

 slender dusky line; cilia ochraceous-ash, spotted with fuscous; anterior 

 stigma very large, pale yellowish-ash, with a delicate fuscous margin, and 

 sometimes a dusky centre : posterior wings fuscous-ash, with the margin, and 

 a striga behind the middle, darker : antennae bright luteous, with the base 

 more or less cinerascent. 



In some examples, the anterior wings have one or more additional black trans- 

 verse strigfe, especially towards the base, and in others the strigse are nearly 

 obliterated.
