Head and thorax white, with delicate fuscous or black waves: anterior wings 

 snow-white at the base and apex, the centre with a broad fuscous fascia, 

 which is bounded on each side with a whitish or subfulvous striga, and 

 marked with undated black sti-igte within : the stigmata are cinereous, with 

 white margins : on the white gi-ound at the base is a geminated black costal 

 striga, and on that of the apex some obsolete fuscous clouds, with a sub- 

 triangular fuscous spot on the costa: cilia pale cinereous, spotted with white : 

 posterior wings cinereous, with a central spot and the margin fuscous: cUia 

 white. 



Very variable in colour : in some examples the central fascia is nearly ochraceous : 

 in others very deep fuscous, and of all intermediate shades; the wliite is 

 sometimes sullied, and much clouded towards the hinder margin of the 

 wing. 



Caterpillar feeds on the Hieracium umbellatum, Leontodon hispidum, Sonchus 

 palustris, &c. :— the imago is produced towards the end of June. 



Not very common, but rather more so in some years than 

 others: in June, 1819, in passing a pollard and rotten ash in the lane 

 leading from Dartford to the common, in company with the late 

 Mr. Blunt, we found the trunk literally covered with this insect, 

 there being several dozens reposing thereon; and from them I 

 selected the series which I at present possess.

 nehulisque atris spar sis, strigd pallida versus marginem posticum. (Exp.

Head greenish-brown, with a rosy tinge : thorax gi-een, with dusky and white 

 atoms: anterior wings greenish, varied with cinereous and rufous, with 

 several obhque abbreviated black streaks on the costa, and obscure strigas on 

 the disc : the ordinary stigmata rather pale-gi"een, with a similar coloured spot 

 nearly adjoining the anterior one, towards the inner margin; near the hinder 

 margin of the wing, which is sometimes rather pale, is a pale undated 

 striga, producing some irregular trigonate black spots on its outer edge: 

 on the margin of the wing is a series of minute trigonate black spots : cilia 

 greenish, spotted with fuscous : posterior wings cinereous, with a fuscous 

 lunule: the centre and the margin fuscous, the latter with a pale striga, 

 sometimes clouded with fuscous. 



Extremely variable : in some examples the anterior wings are nearly of an 

 uniform pale-green, with a few black strigae ; in others, they are of a dark 

 Haustellata. Vol. III. 1st August, 1829. d
