INSECTS AFFECTING THE STALKS. THE SNOWY TREE CRICKET. ((EcttnthiiK nireus DeG. Fig. 20.) This insect is of little economic importance in the cotton field, beinof beneficial, if anything: l)ut the fact that the eggs found in the stalks in winter have been generally mistaken for those of the boll weevil by persons unacquainted with the habits of the latter insect makes it of interest. The eggs are laid in the fall in the stalks of cotton and various large weeds. The}' are arranged in a 1 o n g 11ud i nal row. and form a scar with .

These eggs hatch in early spring and the young feed upon plant lice. The habits of the nymphs have been well described by Prof. C. O. Hough- ton," and our observations confirm his statements regarding the food habits, except that we have observed the adults to feed somewhat upon the tender portions of the foliage. The young become full grown by the middle or latter part of June in Texas, whereas in Delaware they did not mature until Jul}- In the North there is but one generation a year, but there seems to be good evidence that two generations occur in Texas. Two females were placed in a cage June 12, 1904, at which time the adults were common. A week later it was observed that the leaf petiole had been eaten until almost severed and the lobes of the leaves had also been attacked for food. July 1 it was found that the under- side of the petiole toward
