 either deep rose-color or dirty rcddisli-brown, w itli a series of reddish lozeiigt;- 

 shapcd spots down the center of the l)ack, generally beconnng fiiint or con- 

 fluent toward the head or tail. In the green variety, these spots are often 

 entirely wanting; on each side is a number of narrow, slanting, yellow stripes, 

 forming a sort of border to the dorsal spots; spiracular line waved, yellow; 

 body wrinkled, thickly studded with minute white tubercles, and somewhat 

 more sparingly with short white hairs ; segmental divisions yellow ; it is thick 

 and stumpy, tapering but little. It feeds, from the end of August to tiie begin- 

 ning of November, on the flowers of the common yeUow and hoary-leaved 

 ragwort {Senecio jacohcea and <S'. enicifolius), on the hemp-agrimony {Eupa- 

 tonu7n cannahhium), the mugwort {Artemisia vulgaris), the yarrow {Achillea 

 millefoHum), the golden-rod {Solidago virgaurea), and other plants. The 

 chrysalis, which is inclosed in a tightly-si)an earthen cocoon, has the wing- 

 cases bright-green, the rays very |)romiiient, the thorax yellowish-green, and 

 the body reddish-yellow, with a dark-green dorsal line." — Newmans British

2 5. — A little lighter in hue than E. ahsynthiuta; similar to that species 

 in form, but the body is much stouter, with the w ings much mor(> produced 

 toward the apex, which is much less rounded than in ahsi/nthiafa ; while the 

 outer edge of the wing is sinuous, that oi' absj/nthiata being full. Palpi rather 

 longer and larger than in that species. Fore wings crossed l)y about ten 

 slight, wavy, dark lines, bent outward a little below the costa; the lines 

 become more oblique beyond the discal dot; the line situated half way 

 between tiie discal dot and the edge of the wing is_ curved inward between 

 the costal edge and the last subcostal vein. The usual submarginal white line 

 is present, but the white spot on the inner edge, is slightly marked. The 

 discal dot is much smaller and more linear than in ahsynihiata. The hind 

 wings arc much as in that species, but the lines are much finer and narrower; 

 beneath of the same tint as above, with the lines feebly reproduced, the most 

 conspicuous line being the one situated midway between the discal dot and 

 the outer edge of the wing. There are several dark spots on the costa. 



Length of body, 5, 0.45; of fore wings, 5, 0.50; expanse of wings, 1.00 



inch.
