Antenna? cinereous: male with the thorax and abdomen fulvous, the former 

 white anteriorly : anterior wings griseous, irrorated with whitish, with three 

 strigae, the first oblique, abbreviated, purplish, edged with black; the second 

 behind the middle considerably waved and purphsh, edged with black ; the last 

 on the hinder margin whitish, the margin itself dusky: between the two anterior 

 strigjE is an elongate whitish patch, in which is a large nictitating ocellus, 

 having a black pupil, with a white lunule, or griseous iris, encircled with black, 

 and bearing a bluish lunule towards the base of the wing : the apex of the 

 wing is purplish, with one or two black, white, and rufous spots : posterior 

 wings tawny-ferruginous, slightly clouded with griseous, with a central nicti- 

 tating ocellus, as in the anterior, a griseous posterior fascia, and a dusky or 

 purplish hinder margin. Female larger and paler, thorax brown posteriorly : 

 abdomen fuscous, with the margins of the segments whitish. 



Both sexes vary considerably, especially the females : in some specimens of the 

 latter all the wings are beautifully suffused with purplish; in others, the 

 margin and strigae of the anterior wings alone are purplish, and some are 

 nearly destitute of the purplish hue : the bulk also varies. 



pilose, tufted at the apex : wings entire^ broad, horizontally expanded ; poste- 

 rior simple : cilia moderate. Larva naked, fleshy, the back subnodose : pupa 

 slightly hairy, folliculated.

 Ph. At. Tau. Linne.— Martyn. — Ag. Tau. Steph. Catal. No. 5984. 



Testaceous : wings above with a slightly arcuated dusky line near the posterior 

 margin, with a large discoidal subviolaceous ocellus on each, having a white 

 mark, resembling the letter T, for a pupil : beneath paler, or yellowish : 

 anterior with an ocellus as above, a faint dusky streak towards the hinder 

 margin, and a pale spot at the apex on the costa ; posterior pale testaceous, 

 with a trifid central white spot on an oblique deep broad streak, with a whitish 

 line on the hinder margin, and another parallel with it, between it and the 

 central blotch. Female similar, but of a paler colour, and larger. 



Caterpillar green, with oblique lateral white streaks : when young it bears five 

 elongate rufous dorsal appendages : it feeds on birch, lime, hazel, oak, willow, 

 beech, alder, and fruit trees : the pupa is brown : the male flies by day (in 

 May). 



" The place of this fine species in Lepidoptera Britannica rests solely on the 

 authority of Martyn, in his Aurelian's Vade Mec\x\n."—Haworth, L.B. 79. 

 It has not occurred in Britain, to my knowledge, subsequcully to the appear- 

 ance of the above note in 1802.
