504 SAW-FLY OF THE VINE. 



brown veins. The female is one-quarter of an inch 

 in length ; the male, somewhat shorter. They rise 

 at irregular intervals from the ground, and lay their 

 eggs on the under part of the terminal leaves. In 

 July these hatch. 



The larva commences at the edge of the leaf, and 

 consumes all the soft parts, working in company 

 with a dozen or twenty. It is a little more than an 

 inch in length, and has twenty-two legs. The head 

 and tail are black, the upper parts of the body light 

 green, and the lower yellowish ; becoming more 

 yellow at every moulting. After attaining their 

 size they excavate, and line with silk little cavi- 

 ties in the earth. In about two weeks they come 

 forth, and again lay eggs. The young from these 

 remain in the ground as chrysalids all the winter. 

 The larvae may be destroyed by immersion in a 

 solution of whale-oil soap and water, or by dusting 

 with air-slacked lime. The solution of soap should 

 be in the proportion of two pounds to fifteen gallons 

 of water (Harris).

 worms feed upon the tender roots of all sorts of 

 plants. During May they make their appearance. 

 The beetles are brown ; " the atennae nine or ten
