This species of twig girdler also attacks the apple, pear, persimmon, elm, and other kinds of trees, and with those like the apple, with a soft and brittle wood, the girdled twigs are frequently broken off by the winds; but this rarely occurs with the hickories, and we can usually find the stumps remaining on the trees years after the beetles have emerged. The only way to keep this pest in check is to cut off and burn the girdled twigs any time before the larvæ have reached maturity, and as the girdled dead twigs are readily seen, the gathering is not difficult, from medium-sized trees. THE PAINTED HICKORY BORER (_Cyllene pictus._ Drury).--This is, perhaps, one of the most common and widely distributed of all the hickory borers, but, so far as my observations have extended, it rarely attacks young or healthy trees of any age; in fact, I have never found it in or about growing trees, but I have seen it, by the thousands, breeding in decaying specimens and in hickory cordwood cut during the winter months and ranked up in shady places. A hickory tree cut down in fall or winter, and left on the ground or cut up into cordwood, is pretty sure to attract this borer early in spring, the females swarming over the bark, depositing their eggs upon it, and by the ensuing autumn the wood will be fairly honeycombed if this insect is at all abundant. The general color of the beetle is black, and the size as shown in Fig. 71. There are three narrow, whitish bands across the top of the thorax, and one slightly broader band at the extreme point of the wing-covers; but the next band is in the form of an inverted V; the point of the [Inverted V] does not quite touch the broad lateral band, as in the closely allied species known as the locust borer (_C. robiniæ_), with which it is often confounded; besides, in the latter the markings are of a deep yellow, and not white or of a faint yellowish tinge. The hickory borer always appears in spring, and the locust borer in the fall, not later than September in this part of the country. Below or behind the V-shaped band there are three others, but all broken up into mere dots, and not continuous. [Illustration: FIG. 71. HICKORY BORER.] In the South, and especially in Texas, there is a somewhat smaller but closely allied species (_Cyllene crinicornis_) that attacks the pecan tree and its wood in the same way as our common hickory borer, but in the Southern or Southwestern species the bands on the wing-covers are all interrupted or broken up into small white spots or dots. I have no remedy to suggest, further than to cut down old, infested trees, and to haul the wood out into the sun and spread it out where it will quickly dry and become seasoned. If the felled tree and wood is stripped of its bark as soon as cut, the female beetles will not deposit their eggs upon it.
