THE SPOTTED VINE BEETLE. 505 



upper jaws are furnished at the base, on the mner 

 side, with an oval space, crossed by ridges for grind- 

 ing. The thorax is transversely square. At times 

 they attack the vine very furiously, depriving it of 

 foliage. The only remedy is to pluck them by 

 hand " (Harris). 



(4) The Spotted Vine Beetle — Pelidnota jmnctata. 

 The larva exists in decayed wood and roots, and the 

 beetle attacks the leaves, sometimes in large quan- 

 tity. " The wing-covers are dull brownish yellow, 

 with three distinct black dots on each. The thorax 

 is darker, with a black spot on each side. The 

 body beneath, and the legs, are deep bronzed 

 green." They are about an inch in length, and 

 can be readily detected and plucked off by hand 

 (Harris). 



(5) The Vine Pyralis — Tortrix vitana. This is 

 an insect which causes immense damage to the vine- 

 yards of France, by consuming the young foliage. 

 The moth is nearly an inch in the spread of its 

 fore wings, which are green and glossy, with three 

 transverse brown lines. The remainder is brown. 

 The female deposits her eggs on the leaves during 

 the month of July. When the larva comes forth it 

 hangs from the leaf, and eats the young foliage dur- 

 ing the summer. The caterpillar is green, except 

 the head and first segment of the body, which are 

 brown. When the winter commences they hide 

 themselves, by a silken cover, under the dead bark.
