shaped, shining ; the shield is also jet-black and shining behind, 

 whitish green in front, not divided by a dorsal line ; the spots 

 on the body are small, smoky coloured ; the twelfth segment 

 bearing darkish oval spots, the anal segment with a large round- 

 ish smoke-coloured patch ; on the under surface of a yellowish- 

 green colour, the legs inclining to ferruginous. It feeds upon 

 the Sallow, on the young leaves and shoots, and before assuming 

 the pupa state it spins a white silken web between the leaves of 

 the food plant.

Head dull smoky brown. Face rather paler than the head. Eyes 

 black. Palpi as long as the head, smoky black. Antennae deep 

 fuscous, shining. Thorax and patagia dull brown. Anterior wings 

 chestnut-brown, darkest at the base, with a triangulate pale sulphur- 

 coloured or white blotch upon the dorsal margin. The costa is marked 

 with produced geminated streaks, both before and beyond the middle, 

 of a slightly violet-colour ; those towards the apex also with a 

 golden tinge. The apical spot dark and distinct. The base is streaked 

 transversely with violet-tinged wavy lines, and from the middle of 

 the costa proceeds a rich dull brown fascia, with angulated edges, 

 and dilating as it attains the dorsal margin. The ocelloid patch is 

 indistinct, and consists of a golden-brown mark with longitudinal 

 black lines. The dorsal blotch with a very small dusky mark at the 

 margin. Apical scales umber. Cilia shining, iron-grey, becoming 

 dull brown at the anal angle. Posterior wings rich bronze-brown, 

 with a purplish tinge towards the base. Marginal scales fuscous, 

 with straw- coloured bases. Cilia pale fuscous, with an ochreous 

 tinge. Abdomen dark fuscous, the caudal tuft drab. $ Exp. al. 

 5-5-i- lin. Rather paler than the <$ , and the violet-lustred streaks 

 more evident. 



Rather a common insect, and tolerably constant. In size and 

 appearance it mostly resembles S. Populana, but is distinguished 

 from it by the blotch on the dorsal margin, being smaller, more 

 regularly triangular, and almost destitute of markings therein. 



The imago appears from June to August, in hedges, at Da- 

 renth, Birch, and Wickham Woods, near Croydon, Mickleham, 

 in Cheshire, &c. It likewise occurs in the vicinity of Dublin.
