 depression on each side, and a feeble

Throughout the State ; common. Slay 18-July 22. Occurs on 

 the foliage and stems of blackberry and raspberry bushes, in the 

 canes of which the larvas bore, forming galls on some varieties. 

 The.se should be cut out in winter and burned with the enclosed 

 grub ; or the shoots made up to the first of July should be cut off at 

 the surface, because in them the larva' of a new brood are con- 

 tained. The shoots formed later in the season will be sufficient for 

 the next year's crop of fruit.
