216 HAUSTELLATA. — LEPIDOPTERA. 



base, and a broad black one in the middle, with its centre paler, and having 

 a black dot towards the costa, the outer margin strongly unangulated and 

 bordered with a fine whitish line ; between this and the hinder margin is a 

 faint undulated whitish striga, within which is a geminated fuscous spot, as 

 in the other species of this genera, but very faint ; between which and the 

 apex of the wing, on the hinder margin is a subquadrate darker spot: posterior 

 wings fuscous, with one or more transverse pale strigae. 



Variable in the form and intensity of the central fascia on the anterior wings : 

 in some examples the dark varied streaks of which it is composed are very 

 distinct, with the central space, especially towards the costa, nearly as pale as 

 the ground of the wings, with the central black dot very large and conspi- 

 cuous ; in others it is nearly solid : it is occasionally very broad, and some- 

 times considerably attenuated towards the inner margin. 



Caterpillar light-brown, with dirty-grey streaks and a few black spots ; it feeds 

 on the plantain, dandehon, &c. :— the imago appears towards the middle or 

 end of July. 



Somewhat rare : I have however taken the insect several times 

 at Daren th, and occasionally at Hertford and Ripley : it has also 

 been found in Norfolk and Suffolk. " Orton." — T. C. Heysliam,

Wings whitish, or cinereous, fasciated with purplish-red, the fasciae extremely 

 variable ; the base is generally purplish, followed by a narrow striga of the 

 same, and then by a broad, more or less solid fascia, and occasionally tinted 

 with fuscous, and bilobed on the outer margin, which, as well as the inner 

 edge, is bordered by a whitish space, in which is a slender waved fuscescent 

 striga ; beyond this is an irregular purplish-red fascia, shaded off externally 

 into the ashy or whiter border of the wing, in which is a double brown or 

 black spot, and a more or less evident undulated white striga, and on the 

 outer margin itself are some black dots, sometimes united with a faint striga : 

 posterior wings fuscescent, more or less transversely striated with waved 

 cinereous strigae. 



Extremely variable both in the colour of the fasciae and in their width, the 

 central one being frequently broken up into several narrow ones, sometimes 

 so wide as to occupy above half the surface of the wings : in some instances 

 it is of a clear immaculate uniform hue, while in others it is transversed with 

 much darker or paler strigae ; but in all cases the abdomen has a double row 

 of black dots down the back.
