Goldsmith beetle, Cotalpa laitigera. yields readily to any of the arsenites. The larvae live in light soil, feed upon the roots of grasses, and pupate in late fall, the adult forming soon after and remaining within the cast larval skin until ready to emerge in early summer. Also found during the day on grape foliage, or flying toward it during early evening, is a large, shining, tan-yellow chafer, with eight black spots, two on the thorax and six on the wing- covers. Th
. Economic entomology for the farmer and the fruit grower, and for use as a text-book in agricultural schools and colleges; . Goldsmith beetle, Cotalpa laitigera. yields readily to any of the arsenites. The larvae live in light soil, feed upon the roots of grasses, and pupate in late fall, the adult forming soon after and remaining within the cast larval skin until ready to emerge in early summer. Also found during the day on grape foliage, or flying toward it during early evening, is a large, shining, tan-yellow chafer, with eight black spots, two on the thorax and six on the wing- covers. This is the Pelidnota punctata, or '' spotted vine-chafer,'' which feeds upon the leaves, but rarely does noticeable injury. The larvae feed upon decaying roots and stumps, and I have taken both larva and pupa out of a rotten cedar trunk. Swamp-willow in the East is the food of Cotalpa lanigera, a beetle very similar in size and shape to the preceding, but of a beautiful shining, lemon yellow, the head glittering with a golden sheen, hence known as the ''goldsmith ; Beneath it is of a burnished copper color, densely clothed with white woolly hair. It is not injurious, and mentioned here only because of its beauty. Some of its allies in the Southwest and in the tropics are of the most brilliant golden and silvery tints.
