Mr. D. W. Coquillett, in the Germautown TeUgraph, has this to say about curran t borers: "These borers are produced froni eggs which were laid by the parent motb on the outside oí a bud, onlv one egg being consigned to one bush. As soon a hatched, the young borer guaws its way into the stem and continúes its course downward, (casting its chips uut of the hole by which it had entered the stem. Wlien about to assume the chrysalis form it repairs to a place a short distance below the orífice on tho stem and closes its burrow beneath it. .lust befwre being changed to a rnoth the chrysalis, by means of small hooks situated on each side of its body, works itself up to and sometimes partially out ol' the liole which the caterpillar liad previoiisly gnawed through the stem; and white in this position the perfect moth makes its escape. The currant borer moth more nearly resembles a wasp than it does one of those insect which are commonly called moths. lts body is black and is f urnished with a fan-shaped tail, by which it may be readily distinuished from inseets of the wasp kind. On the back of its abdomen are three or four trans verse gold-colored lines. lts wings are transparant, their edges black, and the fore wings are crossed near the middle of a black spot; the ürn of the fore wings are also black. Tlie fore wings expand abont threefourtha of an inch. Cuirant bushes which are infested by these borers should be cut off close to the ground and burned. This should be done in the latter part of April or beginning of May. lt delayed untü after the middle of May some of the moths will have completed theirtianafonnaüon and escaped.
