on the Yine above ground, and we are led to examine the 

 roots. Here we discover the true cause of death, for the 

 roots are found to be pierced here and there with small 

 holes, and excoriated to such an extent that they present 

 a corroded appearance. Upon a closer examination the 

 authors of this mischief are easily detected, either im- 

 bedded in the root, or lurking in some of the corroded 

 furrows. They are little whitish worms, rather more 

 than a third of an inch long, and as thick as a good-sized 

 pin ; the head is blackish-brown and horuy, and there is 

 a plate of the same color and 

 consistency on the last seg- 

 ment. These worms are in 

 fact the young of the same 

 Striped-Bug which had been 

 so troublesome on the leaves 

 earlier in the season; and 

 that the insect may be as 

 well known in this its masked 

 form, as it is in the beetle 

 state, I present the annexed 

 highly-magnified figures of 

 the worm (fig. 28) showing a 

 back, and fig. 29 a side view. 

 The beetles, while feasting 

 themselves on the tender 

 leaves of the vine, were also pairing, and these worms 

 were hatched from the eggs deposited near the roots by 

 the females. When the worms have become full-grown, 

 which is in about a month after they hatch, they forsake 

 the roots and retire into the adjoining earth, where each 

 one, by continually turning around and around, and com- 

 pacting the earth on all sides, forms for itself a little 

 cavity, and in a few days throws olf its larva skin and 

 becomes a pupa. This pupa is much shorter than was 

 the worm, and the insect lasts in this state about
