118 HAUSTELLATA. — LEPIDOPTERA. 



come beneath my observation ; the first was foimd nearly thirty 

 years since, by Mr. Hatchett, in the neighbourhood of London ; 

 but unfortunately his specimen was accidentally destroyed : the 

 second was taken in June, 1817, by the late Mr. Blunt, near West 

 Ham, in Essex : and the third (whence the accompanying figure 

 was obtained) occurred near Cork, in June, 1826, and is in Mr, 

 Stone's rich cabinet of Lepidoptera. 



Sp. 7. valligera; Alis anticis griseo-fuscoque variis, maculd ohlongd haseos nigri- 

 cante, jmncto-ocellari ferrugineo. (Exp. alar. 1 unc. 4 — 8 lin.) 



No. valligera. Wien. V. — Ag. valligera. Steph. Catal. part \i. p. 66. No. 6087. 

 Ph. Bo. clavis. Don. x. pi. 340. /. 2. 



Head griseous, varied with white ; thorax anteriorly griseous, with two trans- 

 verse dusky lines, and two whitish ones, and the back griseous mixed with 

 white ; the petagiae white, with griseous borders : anterior wings pale griseous, 

 varied with fuscous, the costa spotted with white ; in the middle of the base 

 is a black spot, adjoining to which, on the inner edge, is an ocellated ferru- 

 ginous patch, with a pale iris, from which the teliform stigma, which is very 

 stout and dusky, with a darker margin, arises ; between this and the costa fol- 

 lowing the discoidal nerve is a broad whitish streak; the anterior stigma is 

 small, rounded, with a dusky pupil, and edged with black ; the posterior is 

 dusky, margined with black and white, with a small spine-like black lineola 

 on the hinder edge ; on the hinder margin is a striga of arrow-shaped black 

 lines, and a whitish one behind, very much waved, with a mark towards the 

 anal angle resembling the letter ^V : the fringe is pale at the base and brown 

 at the tip : the posterior wings are white in the male, and dusky, with a darker 

 margin, in the female 



Var. fi. Anterior wings darker, without the spiniform process to the posterior 

 Btigma. 



Like its congeners, this beautiful species varies greatly. In some examples the 

 ground colour is of a beautiful leaden- or bluish-gray, and the usual markings 

 are greatly suffused :— in others the colour is lighter, with faint markings. 



Caterpillar ashy-gray, with a brown head, each segment with four black spots: 

 it feeds on grass : the imago appears in August. 



A scarce species ; it occurs, however, in very remote parts of the 



here take occasion to remark upon the importance of attending to minute dif- 

 ferences in the examination of specimens from distant parts: if the British 

 specimens of Ag. annexa had been strictly examined with those of No. sub- 

 terranea, their distinction woiUd soon have been evident, and an error in the 

 geographical station of the species would not have been committed, and have 

 remained uncorrected till now, although the genus has been recently investi- 

 gated in this country.
