The resulting moth, Benibecia marginata, is black, very' little marked with yellow, and the only satisfactory remedy is cutting out and destroying the larva as soon as its presence is indicated by the wilting leaves. Perhaps the best known of all belonging to this series is the "peach-borer," Sa?ini7ia exitiosa. This is the pest of peach- growers all over the country, and the larvae live between bark and wood a little below the surface of the ground in a mass of gum and woody material. They first make their appearance after midsummer, and become about three- fourths of an inch long before winter sets in. In spring they resume feed- ing, attaining a length of a little more than an inch, then spin a cocoon of silk and bits of chips covered with gum, and change to a pupa. In this stage they remain a few days and then emerge as moths. The sexes are very unlike, the males t)lack, with narrowly yel- low-banded abdomen, and entirely transparent wings ; the females much larger, the fore-wings almost blackish brown and entirely covered with scales, the abdomen black, with a broad orange band at about the middle. The eggs are laid on the bark near the surface of the ground, and the larvae hatch after miasummer in time to do con-. peach-borer, Sannhia exitiosa; male above, female below ; both Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations
