black, and has a row of spots of the latter colour on the margin ; cilia white 



slightly clouded with fuscous : posterior wings also white, with a few black 



dots oil the inner margin, and some brownish waved striga; behind the middle :

 Slightly variable: in some examples the anterior wings are clouded with fuscous 



and- black in the middle; and the posterior have a distinct subcentral fuscous 



fascia. 

 Caterpillar green, with a white marginal spot, dotted with red ; it feeds on the 



spindle-tree (Euonymus Europaeus) : — the imago appears at the end of June, 



and towards the middle or end of August.

Head and thorax fuscous : anterior wings snow-white, with the base red-brown 

 or dusky : an irregidar interrupted fascia in the middle, very much attenuated 

 towards the inner margin and usually interrupted in the middle, with a con- 

 spicuous somewhat ocellar black dot towards the costaj the posterior margin 

 lead-coloured, with an undulated whitish striga: posterior wings also snowy, 

 with a fuscous dot in the middle of the hinder margin pale lead-colour, with 

 a faint whitish striga. 



A little variable in the form of the central fascia on the anterior wings. 



Caterpillar slender, green, with a pale dorsal line and a yellowish-green lateral 

 one; it feeds on the alder: — the imago appears towards the end of June, 

 and a second time about the end of August. 



Also local, but at times extremely abundant : in 1827 it abounded 

 in a garden at Ripley, so as to become a pest of an evening.
