176 LEPIDOPTERA. 



towards the apex with dark colour from the band. Female 

 quite similar. 



Underside a fainter copy of the upper, but with a black 

 spot on the costal margin of the hind wings. Body and legs 

 white. 



There is a well-recognised recurrent variety, known as A. 

 lucida, in which considerable bluish-brown clouding in the 

 white basal area of the fore wings seems to suggest cloudy 

 basal and first lines ; in this the ovate white blotch at the 

 anal angle is also rather obscured, and smoky-black streaks 

 or shades run from the base of the hind wings, in the female 

 darkening them considerably. 



On the wing in May, June, and August, in two genera- 

 tions. 



Larva thick but rather attenuated in front, naked, having 

 only twelve feet, the eleventh segment rather raised ; head 

 small, red-brown edged with yellow ; body red-brown through- 

 out with delicate dull yellow flecks and rippling lines ; dorsal 

 plate angular, shining, of the body colour ; dorsal and side 

 lines only very faintly indicated ; raised dots small, dark 

 brown with their bases yellowish; anal plate yellowish dotted 

 with black ; spiracular lines very slender, waved, consisting 

 of the most minute yellow dots ; spiracles white edged with 

 black ; on the back of the fourth to the sixth segments 

 inclusive is a dark red-brown blotch edged by an oblique 

 yellowish line, and on the eighth and ninth a fine yellowish 

 line from the spiracular line downwards to beneath the pro- 

 legs, which are of the colour of the body. 



June, July, and September, in two generations, upon 

 Convolvulus arvcnsis and Malm rotundifolia, in dry places.

Pupa apparently undescribed, in the earth. 



From its extreme rarity scarcely anything is known in this 

 country of the habits of this moth ; but it is on record that
