towards the base, the other behind the middle, with a round fuscous spot 



between, towards the costa ; posterior wings immaculate. 

 Var. (i. With a fuscous cloud at the base of the anterior wings, on the costa; 



and a dcKticulated striga on the hinder margin. 

 Caterpillar hairy, brown ; it feeds upon lichens : pupa brown, with the abdomen 



greenish, speckled with black : the imago appears in August, and frequents 



hedges. 



Not uncommon in several places near London ; in great plenty 

 near Ripley, and also at Darenth-wood near Hertford. " Alderly,

Distinguished by the transparency of its wings, which are beautifully iridescent : 

 immaculate, with the nervures slightly tinged with ochraceous, the entire 

 margin squamous, and with the fringe lutescent or yellowish. 



Were it not that I have frequently reared this insect from the larva, I should be 

 induced to think, with Ochsenheimer, that it was a mere wasted example of the 

 foregoing species ; but on first emerging from the pupa, the wings have been 

 perfectly transparent and immaculate. 



Taken occasionally at Darenth-wood at the end of July.

Bo. senex. HUbner.—'Nu. senex. Steph. Catal. No. 6042. 



Antennas, head, thorax, abdomen and legs pale ochraceous, or cinerascent : wings 

 rounded, anterior lutescent, with a round dusky spot a little beyond the 

 middle, various minute brown spots on the nervures towards the base, disposed 

 in a striga, and between the larger spots and the margin a series of elongate 

 spots or lineolse also on the nervures; the tip of the wing a little clouded with 

 dusky, the ciha flavescent, with dusky spots : posterior wings rather paler, with 

 some obsolete spots towards the margin, and a larger central lunate one : cilia 

 flavescent, obsoletely spotted with dusky. There is sometimes a dusky patch 

 at the base of the anterior wings, and the costa is clouded with the same colour. 

 ^' ery scarce near London ; two or three specimens, of which I 



possess one, have been taken in Battersea-fields ; but on the borders 



of Whittlesea Mere the insect occurred in considerable plenty in 



July 1825, and the following season.
