cT ? . Structurally very close to po/iu/i. (ironud-colour variable as in that 

 Bpecies. The rufous jiatch of the hiiidwiiig absent or barely indicated, llai'iie 

 mnch broader than in pojjtdi, the two lobes being very broad ; the sheath of the 

 penis miillispinose almost all round the edge, the spines small on one side of 

 the sheath ; tenth tergite shorter than in popnli, steriiite more evenly convex 

 below, its sides straighter, the ape.x more obtuse. Vaginal plate as in populi, the 

 ridge in front of the vaginal cavity shallowly emarginate. 



Larva described and figured by Fisher, I.e. — Food-plants : Populus trcmula 

 and lancifoUa. 



Treitschke describes the larva as not chagreened, being sometimes (juite glossy 

 as if varnished ; he further states that there are no side-bands, or only traces of 

 them, that the head is more rounded than triangular, and that the horn is long and 

 occasionally carmine-red. This description, which Dupouchel doubts as being 

 correct and which Boisdnval calls absurd, has been copied over and over again by 

 the writers on Palaearctic Lepidojitera.
