long, held out straight, their tips slightly retractile, but armed with 

 hooks. A white dorsal stripe finely margined with dark brown and 

 containing in its widest places a fine double line, is yellowish ante- 

 riorly on joint 2, widens on joints 4-6, and ends on joint 8. It 

 begins again on joint 9, yellowish; widens, forks on joint 11, the 

 parts converging on joint 13, and passing on to the anal feet, but not 

 meeting. Body leaf green, with many small black dots and three 

 purple-brown lateral patches mottled (especially the upper part of 

 the last two) with crimson or pale crimson, which later becomes 

 pale pink or cream color. The first on joints 4 and 5 upwardly ob- 

 lique, covering the spiracle on joint 5; the second large, on joints 

 7 and 8, covering the foot on joint 7, not reaching below the spiracle 

 on joint 8, but attaining the dorsal band; the third, on joint 10, 

 covering the spiracle, downwardly oblique posteriorly and passing 

 on to the foot. Anal feet purplish, thoracic brown ringed with black, 

 abdominal tipped with brown. Spiracles yellowish centrally, broadly 

 brow^n outwardly. As the stage advances a diffuse, white, subdorsal 

 band appears on joints 8-10, tapering at each end and forming a 

 condnuation ol the widest places of the dorsal band, but narrowly 

 separated from it, or only pardy confluent, but there is considerable 

 variation in this character in different examples; also a narrow white 

 dorsal line encroaches on the anterior part of the green patch formed 

 by the furcation of the dorsal band on joints 11 and 12, while the 

 anal plate, between the branches, is brown. The fine lines in the 

 white dorsal band become pulverulent, thus approaching in appear- 

 ance the numerous black dots of the lateral region. In the upper 

 part of the third lateral patch a round, cream-colored spot appears, 

 formed by the confluence of the motdings. Length 30 mm. 



Cocoon. — Formed under rubbish, or just under the surface of 

 the ground of silk and grains of dirt. It is thin and of no strength. 



Pupa.— Cylindrical and slightly tapering. The cremaster con- 

 sists of two thick spines from an elevated base, curving sharply 

 outward and beset with several thorn-like branches. Body punc- 

 tured, cases smooth. Color dark red-brown, polished. Length 

 about 20 mm. ; width 6 mm. 



Duration of this stage: first brood, 14 days; second brood, 

 over Winter. 



Food-Plants. — Witch \\3.zQ\{Hamamelis), Hickory (G?n'«), 

 Maple {Acer), Birch {Betii/a), Dogwood (Cornns), and probably 

 others. The Witch Hazel seems to be the most usual food-plant, 

 and the larva is very inconspicuous upon this plant when see'n from 

 above in spite of its bright markings, as it resembles the curled and
