paler than the disk of the wing, with slender black edge-lines ; beyond the stigmata is another arched black line

directed outwards, and edged externally with gray, followed by two obsolete, lunulated strige, and two or three 
black dashes near the tip: the hind wings dusky, with the margin and central lunule darker. The caterpillar is 
olive-green, with white streaks on the pedigerous segments; the two following with large black spots on the 
back, and all the following with lateral, oblique, white streaks, edged with black. It feeds on the common nettle 
and the moth appears in July, and is a common species in the south of England. 
SPECIES 2.—ABROSTOLA URTICH. Puare L., Fre. 8, 9. 
Synonymes. — Noctua urtice, Hubner; Stephens ; Wood, Ind. Noctua asclepiadis, Haworth. 
Ent. pl. 16, fig. 394. Noctua triplacea, Donovan, 9, pl. 298. 
This species is rather larger and paler-coloured than the preceding ; the thorax is more distinctly marked in 

front, with two ocellated spots; the fore wings are whiter at the base, without any tinge of rust-colour ; the 
stigmata are paler, with black edge-lines; the striga beyond them is less arched, and the striga next the apical 
margin is broader, forming a fascia attenuated towards the apex, where it passes through two black dashes, which 
are confluent. In other respects it closely resembles the preceding, but the caterpillar is different, varying in 
colour from grass-green to fleshy-pink, with a pale line on each side, above the feet ; the fourth and fifth segments 
with a black dorsal patch, and some white spots on the sides of the other segments. It feeds on the nettle, and 
the moth appears in July. It is a common and widely dispersed species. 
SPECIES 3.—ABROSTOLA ASCLEPIADIS. Puare L., Fie. 10, 11. 
Synonyme.—lVoctua asclepiadis, Wien. Verz.; Fabricius ; Stephens ; Wood, Ind. Ent. pl. 54, fig. 50. 
This species measures 1+ inch in the expanse of the fore wings, which are blackish-brown, paler at the base, 
with an abbreviated, duplicated, black, angulated, basal striga, followed by a black one, curved and crossing the 
wing, edged within with rusty-colour ; the characteristic, part of the wing dark, and bearing three stigmata, 
the first and supplemental ones being confluent ; the third striga is straighter and waved, strongly angulated in 
front, and edged externally with rusty ; the fourth striga is pale, wavy, passing through a duplicated black spot 
near the tip of the wings. The hind wings brown, paler at the base. The caterpillar is pale, with black dots, 
and a slender, pale-green, dorsal line, and a yellow lateral stripe. It feeds on Asclepias vincetoxicum. It is 
doubtful whether this be a native species.
