Among the insects that revel in this golden mine in the utumn is a black beetle with numerous transverse or wavy mellow bands (Fig. 695). This beetle is also ound on locust-trees, where it lays its eggs. The larvae bore under the bark and into the lard wood ; they attain their growth in a little ess than a year. The locust-trees have been :ompletely destroyed in some localities by the depredations of these larvae. The Painted Hickory-borer, Cyllene pictiis _ ^C. pic'tus).—This beetle resembles the preced- ng so closely that the same figure will represent either. 3ut the Hickory-borer not only infests a different kind of :ree, but appears in the spring instead of the autumn. In ;his species the second segment of the hind tarsus is densely Dubescent beneath, while it is glabrous in the Locust-borer. The Oak-pruner, Elaphidion villosum (El-a-phid^i-on vil- o'sum).—The work of this insect is much more likely to attract attention than the insect itself. Frequently, in the autumn, the ground beneath oak-trees, and sometimes oeneath apple-trees also, is strewn with small branches that lave been neatly severed from the trees as if with a saw. These branches are sometimes nearly an inch in diameter, and have been cut off by the larva of a beetle, which on ac- count of this habit is called the Oak-pruner. The beetle lays each of its eggs in a small twig. The larva eats out the in- side of this twig, and works down into a larger branch, fol- lowing the centre of it towards the trunk of the tree. When full grown the larva enlarges the burrow suddenly so as nearly to sever the branch from the tree, leaving only the bark and a f
