ATTACKING THE LEAVES.

Fig. 278. 



legs firmly in the web of silk^ sheds its hairy skin and be- 

 comes a chrysalis. 



An odd-looking little thing it is (see Fig. 278, 6), about 

 four-tenths of an inch long, angular and rugged, and when 

 touched it wriggles about very 

 briskly. It has two rather long, 

 compressed horns placed side by 

 side, extending upwards, on the 

 middle of its back; one of these 

 is shown, enlarged, at g; it has also 

 other smaller projecting points and 

 ridges. At first its color is pale 

 yellowish green, but it soon grows 

 darker, becoming reddish brown, 

 with darker spots. It remains in 

 this condition from one to two 

 weeks, when the perfect insect 

 appears. 



The moth, which is shown in 

 the figure at d, is an elegant little 

 insect, its wings measuring, when 

 expanded, about seven-tenths of an 

 inch across. The fore wings are long and narrow, and cleft 

 down the middle about half-way to their base, the posterior 

 half of the wing having a notch in the outer margin. Their 

 color is yellowish brown, with a metallic lustre, and several 

 dull-whitish streaks and spots. The hind wings are similar 

 in color to the anterior pair, and are divided into three lobes ; 

 the lower division is complete, extending to the base, the 

 upper one not more than two-thirds of the distance. The 

 outer and hind margins of the wings, as well as all the edges of 

 their lobes, are bordered with a deep whitish fringe, sprinkled 

 here and there with brown ; the body is long and slender, 

 and a little darker than the wings. The antennae are moder- 

 ately long and thread-like, nearly black, but beautifully dotted 

 with white throughout their whole length. The legs are long.
