figure, the larva — color, white ; lower

When about to assume pupa form 

 (Fig. 202) this borer takes up a posi- 

 tion near the opening of its burrow, 

 and closes the burrow above and below 

 it with its castings, and then spins 



around its body a silken cocoon. Soon after completing this 

 task the borer is changed to a pupa, from which the perfect 

 insect is evolved in the course of a week or so. The latter 

 usually makes its appearance in April or May, and soon after- 

 ward deposits its eggs. 



The fore-wings of the perfect moth (Fig. 203) expand about 

 ten lines ; they are transparent, with the veins and margins 

 black, and crossed near the middle with a black band ; at 

 the tip of each wing is usually a black spot, which is more 

 or less tinged with copper color ; the body is blue-black, with 

 the edges of the collar and shoulder tuft, and three rings on 

 the abdomen, golden yellow.

 blue-black and yellow.

 latter part of April or early in May, spray

 cannot be obtained.
