ATTACKING THE LEAVES. 



345 



measures an inch or more in length, is of a whitish color, with 

 a wide yellow stripe down the back, another of the same char-

 and a number of black 

 spots of different sizes 

 upon each segment. 

 The under side is 

 white with a slight

The eggs, which are 

 very pretty (see Fig. 

 358, which shows one much magnified at a, and others of 

 the natural size at 6), are attached to the stems and twigs in 

 the autumn, and remain in this condition 

 until spring, when they hatch about the 

 time the bushes are in full leaf, the larvae 

 attaining their full growth within three 

 or four weeks. When ready for their 

 next change, they descend to the ground, 

 and, having penetrated a short distance

 Fig. 357), in which condition they remain two or three weeks, 

 or more, when the perfect insects are liberated. 



The moth (Fig. 359) is of a pale-yellowish color, with 

 several dusky spots, which vary in size and form, being more
