ATTACKING THE LEAVES. 



315 



When the larva is about to change to a chrysalis, it spins a 

 loose web of silk on a leaf or other suitable spot, to which 

 the chrysalis is attached. Tiiis is less than three-tenths of an 

 inch long, pointed behind, enlarging gradually towards the 

 front, where, near the end, it slopes abruptly to the tip. Its 

 color is pale green, with a line along the back of a deeper 

 shade, margined on each side with a whitish ridge; it is also 

 more or less hairy. In about a week or ten days the chrys- 

 alis changes to a darker color, shortly after which the perfect 

 insect escapes. 



The moth (Fig. 327), although quite small, is very beauti- 

 ful ; it measures, when its wings are expanded, about half an 

 inch across. The fore wings are of a deep 

 brownish-copper color, with a metallic lustre, 

 and a few dots of silvery white; they are 

 cleft down the middle about half their depth, 

 the division as well as the outer edge being 

 fringed. The hind wings, which resemble 

 the fore wings in color, are divided into three portions, the 

 hinder one being almost linear, and all deeply fringed. The 

 antennae are ringed with silvery white, and there are spots of 

 the same color on the legs and body. 



Should this insect at any time prove troublesome, it might 

 be easily destroyed with powdered hellebore and water, as 

 recommended for No. 181. 



No. 183. — Chelymorpha Aiyus 

 Leichtenstein, a beetle belonging 

 to the family Chrysomelidse, is also 

 said to feed occasionally on the 

 raspberry. In Fig. 328 the beetle 

 is represented of the natural size, 

 the chrysalis in Fig. 329. It can 

 scarcely be regarded as injurious, 

 notice.
