NOCTUIDiE. ABROSTOLA. 97 



teriorly, from thence to the hinder margin fuscous, with another striga be- 

 yond the stigmata, turning in an opposite direction from the first, black an- 

 teriorly and griseous posteriorly ; and between this and the posterior margin 

 are two obsolete, somewhat waved, strigse, composed of pale, indistinctly 

 iunular, spots; and near the costa, at the apex, are two or three black longi- 

 tudinal streaks ; the hinder margin itself has a fine dusky line ; the stigmata 

 are large and rather paler than the ground of the wing, the anterior one ex- 

 tending obliquely over the disc and appearing doubled; cilia fuscous : pos- 

 terior wings dusky cinereous, with a central lunule, and abroad marginal band 

 brownish-black ; cilia dirty-white. 

 Caterpillar green, with a white streak on the three anterior segments, a black 

 spot on the two following, edged with ochraceous, the latter colour passing 

 obliquely downwards in a streak to the lateral line, the remaining segments 

 with an oblique white streak, the colour behind being dusky; — it feeds on the 

 nettle (Urtica dioica) : — the imago appears in July. 



Not very uncommon throughout the metropolitan district, and in 

 the south of Britain, frequenting gardens, wood-sides, &c. I have 

 often captured it in a garden at Hertford. " Epping." — Mr. H. 

 Douhleday.

Deep dusky-black or brown ; -vvings of a fuscous-black, vnth the base paler ; 

 anterior with an arcuated striga at the base, and another behind the middle, 

 turning in the opposite direction ; the costa with black streaks. 



Caterpillar feeds upon the Asclepias Vincetoxicum ; it is pale, spotted with black, 

 with a yellow lateral line. 



Upon a recent collation of the synonyms of this genus, I find that the fol- 

 lowing alterations appear requisite in my Systematic Catalogue, the synonyma 

 there given having been brought together long since. From Ab. Asclepiadis 

 dele the references to Haworth, Samouelle, Donovan, Harris, and Hiibner, 

 and transpose the four first to Ab. Urticae, and the last to Ab. triplasia. 



I have never seen this species, which I have been informed has 

 been captured in the north of England.

Head and thorax brown, the latter with two very distinct subocellated spots in 

 front, edged with brownish-black, behind which is a broad distinct trans-
