in a few days into small dark-brown worms, which feed on the upper 

 side of the leaves, eating numberless holes in the softer parts, in the 

 manner shown in Fig. 10. 

 In about three or four weeks 

 they become full grown, 

 when they present the ap- 

 pearance shown at h, in the 

 Fig.; but "here is a magnified 

 view; the hair-line at the side 

 shows the correct size. They 

 are then about three-tenths 

 of an inch long, usually of a 

 light brown color above, 

 sometimes yellowish, at other 

 times of a darker shade, paler 

 on the under surface. The 

 head is black, and there are six 

 or eight shining black dots on 

 each of the other segments Fig. 10. 



of the body, each emitting a single brownish hair. The feet, six in 

 number, are black, and there is a fleshy orange colored proleg on the 

 terminal segment. WHien progressing, the larvae does not move its 

 body regidarly, but raises it suddenly behind. 



In the early part of June they leave the vines and descend to the 

 ground, where they burrow in the earth, and forming a little smooth 

 oval cell, change to dark yellowish chrysalids, as shown at c, Fig. 10. 

 After remaining about two or three weeks in this state, the perfect 

 beetles issue from them, and the work of destruction still goes on; but 

 as they live altogether on leaves during the fall, of which there is usually 

 an abundance, the injury they do at that season is scarcely noticed. 



To destroy the beetle it is recommended to strew in the fall, air- 

 slacked lime, or a good quantity of unleached ashes around the vines 

 infested. The larvae may be destroyed by the use of hellebore and 

 water, or where it can be safely used, a mixture of paris-gTeen and 

 water, in the proportion of one or two teaspoonfuls to a pail of water. 

 Tliis latter mixture would also doubtless kill the beetles if the vines were 

 well syringed with it in spring. During the chilly mornings of early 

 spring the beetles axe comparatively sluggish and inactive, and some
