Girault records one plant as having 267 punctures and another 115. 



In the course of a few days the larva hatches from the ^%%, eats 

 its way in the woody portion toward the pith which it soon enters 

 and there develops. The larva migrates little if any but simply eats

 or less surrounded with the dark excrernent and other material and 

 it is in this chamber that pupation takes place. By late July pup?e 

 may be found in some of the earlier infested stems. Pupation is of 

 short duration and in early August adults may be observed in some 

 infested plants. These are as usual white at first. They gradually 

 darken and soon the adult emerges through a circular exit hole cut 

 through the side of the stem near the pupal chamber. The descrip- 

 tions of the different stages follow.
