354 SYNOPSIS OF CANADIAN ARCTIADAE. 
Secondaries bright red, with five or six irregular black spots edged 
with yellow, mostly towards the posterior margin. A large patch of 
black at the apex, which is prolonged along the anterior margin, bor- 
dering it to the base. Cilie yellowish. 
Under surface paler than the upper, with the markings less. dis- 
tinct; margins yellow. 
Abdomen red above, whitish at the tip, with a black dorsal 
macular band; black below, with a central row of four or five white 
spots. Legs black, fringed along the thighs and at base with brown ; 
posterior edge of hind tibie whitish. 
Length of body 83 lines. Wings expand 25 lines. 
Larva.—Length one and three quarters to two inches. Head 
black, with a light spot on each side. Body black, with a dorsal 
flesh-colored stripe. A transverse row of prominent tubercles on 
each segment, of a yellowish flesh-color, from which arise tufts of 
stiff hairs, which are black on the back and brown on the sides of 
tke body. Feet and prolegs yellowish, tipped with black. 
This larva, like that of Americana, hybernates when partly grown; 
and completes its growth the following spring. It feeds readily on 
lamb’s quarter (Chenopodium album) or on grass. 
Hab.—London. Not uncommon. Montreal (Mr. D’Urban.) 
A. parthenice closely resembles the following species “ virgo,” 
and has usually been regarded as a mere variety of it; but since the 
larva described above, of which I have reared several specimens, 
does not agree with that of “virgo” as described by Harris, it is 
probable that they are distinct. 
A. virgo !— Hubner. 
Palpi black. Head buff in front; black at the sides. Antenne. 
ferruginous. Thorax buff or flesh-color, with five black spots; two 
small ones in front and three larger on disk. 
Primaries black, margined and striped with buff, flesh-color, or 
sometimes reddish. Veins and their branches striped; two wide: 
longitudinal stripes joined near the base, and extending to the hind 
margin ; the lower one furcate near the end; three transverse from 
costa; the two outermost extending to the hind margin, the inner 
one to the median stripe or just below it. A short transverse stripe 
unites the upper with the lower longitudinal ones beyond the middle.
