Wings white or cream-colour ; the anterior with various dark spots on the costa, 

 towards the apex of which is a large somewhat trigonal fuscous spot, in 

 which is a black lunule ; the posterior margin is ochraceous, with a waved 

 pale hne, and the inner margin sHghtly clouded with fuscous ; ciha ochra- 

 ceous-brown with darker clouds : posterior wings also white, with striga on 

 the inner and posterior margins, and a minute central dot fuscescent. 



In fine examples there are two indented black strigse on the anterior Avings, one 

 before, the other behind, the middle, and enclosing the costal patch. 



Caterpillar green, spotted with white : it feeds on the Centaurea scabiosa and 

 other plants : — the imago appears in June.

 Anterior wings very long and narrow, cinereous, with three very oblique sub- 

 ffiquidistant whitish strigse ; the first straight and very obKque, extending 

 from the costa to the middle of the inner margin ; the second broader, slightly 

 waved, and placed behind the ordinary discoidal black dot ; the last is consi- 

 derably undulated and more conspicuous, being paler: cilia fuscous, with 

 darker clouds : posterior wings cinereous, with various transverse strigse and 

 a conspicuous pale one towards the hinder margin. 

 In some examples the space between the two first strigse on the anterior wings 

 is of a darker hue than the rest of the wing, and forms a distinct unsoUd 

 bar. 



Found in the vicinity of Birch-wood in August ; not uncommon, 

 also, near Darenth, and at Hertford.—" Gibside.''— G. Wailes, Esq,
