cT ? . Structurally very close to poj/ii/i. Ground-colour variable as in that 

 species. The rufous patch of the hindwing absent or barely indicated. Harpe 

 much broader than in popidi, the two lobes being very broad ; the sheath of the 

 penis multispinose almost all round the edge, the sjnnes small on one side of 

 the sheath ; tenth tergite shorter than in popidi, sternite more evenly convex 

 below, its sides straighter, the apex more obtuse. Vaginal plate as in j/opii/i, the 

 ridge in front of the vaginal cavity shallowly eraarginate. 



Larva described and figured by Fisher, I.e. — Food-plants : Fopulus tremula 

 and lancifolia. 



Treitschke describes the larva as not chagrcened, 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 Duponchel doubts as being 

 correct and which Boisduval calls absurd, has been cojiied over and over again by 

 the writers on Palaearctic Lepidoptera.
