In the accompanying cut, fig 5 represents the male and fig 6, the female. Their colour is pale green, and they are. exceedingly lively and musical, chirping merrily among the green leaves all the day. The perfect insects appear in the fall of the year, and it is then that the mischief making female in the carrying out of her instinctive desire to protect her progeny becomes such an enemy to the raspberry grower. She is furnished with a long ovipositor which she thrusts more than half way through the cane and down the opening'' thus made she places one of her long narrow yellow eggs, a second one is then deposited in the same manner alongside of the first, and thus the work is continued until from five to fifteen eggs or more have been placed in a row. The stem of the plant thus operated on is very much weakened, and is liable to break off on very slight provocation, or where this does not occur the branch sometimes dies beyond the punctured part; should it, however, survive and also escape being broken in winter, it is very apt to break from its own weight as soon as the foliage appears in spring, and thus the crop of fruit which would otherwise be secured is lost.
