branch and then the egg-gallery is taken up the twig approximately 

 at right angles to the former direction. This latter *gallery curves

 at work in this gallery. Several pairs of beetles will attack the same 

 twig. In quite a small one three pairs were cut out on May nthj 

 1902. 



I have not yet ascertained how many generations in the year there 

 are, nor how long the insect takes to pass through one generation.
