shaded along the hind margin with smoky-brown; cilia 

 white. Body and legs greyish-brown. 



Apparently not variable. 



On the wing in June and July. 



Larva green with darker green divisions to the segments ; 

 dorsal line slender, white; on each segment are eight red 

 tubercles, except on the last where there are two; among 

 these, on the second and fourth segments, is a shorter 

 yellowish point; above the feet is a broad undulating 

 yellow longitudinal stripe interrupted on each segment; 

 spiracles white, ringed with black; head brown edged 

 behind with black, and having a pale-edged triangle on 

 the forehead; undersurface pale green with two slender 

 longitudinal lines, which are red-brown on the fourth and 

 fifth segments, on the remainder dark green. (Hofmann.) 



August and September on Artemesia campestris, A. ahro-

Pupa yellowish with the front greenish. (Hofmann.)

 include it here as a British species, yet have little doubt of

 A. absynthii in plenty in the north of Pembrokeshire, and
