They remain in the beetle state but a short time, and the damage they do is small as compared â with that which they inflict in their prolonged grub state. The beetle is about an inch long, of the shape shown in figure 44; its legs are long and slender, with sharp claws, by which it can hold readily to the foliage, etc.; it is of a dark-chestnut color, and covered with minute dots; each wing-cover has two or three slighly elevated longitudinal lines, and the breast is covered with a yellowish down. If the small feelers be examined, the knob at the end will be found to consist of three leaf-like plates. Soon after pairing the female enters the earth to the depth of a few inches, she there deposits forty or fifty eggs, and soon dies. The eggs hatch in about a month, and as the grubs are at first quite small, but little is known of their history during their first year, but they no doubt subsist upon any small roots they may come across. In the second year they are large enough to make their presence felt; they then work near the surface, and it seems to make little difference what kind of root they meet with, it is cut off a short distance below the surface of the ground, and the plant wilts and dies. This happens to Indian com, to grass, to tender lettuce in the gar- den, and the woody roots of yonng fruit trees in the nursery, as well as to the more tender ones of the Straw- berry; besides, it often revels in the Fig. gbcb. tubers of the potato, making the crop fit only for the pigs; it also does mischief in the flower gardenâindeed, no live root seems to come amiss to this general feeder. The grub is full-grown in the. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and app
