. The Canadian horticulturist [monthly], 1887. Gardening; Canadian periodicals. THE CANADIAN HORTICULTURIUT. 15. Fig. 1. sight, and to devise means of lessening their ravages. OUR NATIVE CURRANT BORER. is a very small beetle. Figure 1 shows shows it of the natural size at the left band, and at the right magnified in order to present its markings more clearly. It may be found on the currant bushes early in June, and, being not very ac- tive, can be cap- tured, its small size being the greatest obstacle, for by reason of its diminutive- ness it escapes detection. From the eggs laid by this beetle small, white, footless grubs are hatched, having brown head and black jaws. These feed upon the pith of the stems, render- ing them hollow, as many as half a dozen of them being frequently found in one cane. They remain within the stalk, changing into the chrysalis state without leaving it until, as little brown beetles, they come out in the end of May or beginning of June. THE IMPORTED CURRANT BORER, for it seems that somehow, as though we had not pests enough of our own, we must needs bring in some more from foreign countries, belongs to quite a different family of insects, as will be seen at a glance at Figure 2. This little moth is of a bluish black color, with three narrow golden bands across the abdomen. The wings ai-e transparent, veined and bordered with black, having a coppery lustre. It may be found among the currant bushes about the middle of June, laying its eggs singly near the buds, from which the larva? are hatched in a few days. These little worms eat their way into the centre of the cane,.
