Easpberry Saw-fly (Selandria rubi, Harris).-About the time raspberi'ies are in flower the leaves are noticed to bo riddled with small holes. On examination this will be found to be the work of a green, bristly caterpillar (Fig 16). From the close resemblance in colour to the leaves on which they feed, these caterpillars arc sel- dom recognized as the cause of the injury. They disappear irom the canes before July, and' form oval cocoons beneath the ground. From these the perfect insect, a small, dark four- winged fly, | inch long, appears the next May the foliage as soon as the caterpillar's work is detected with white hellebore, ] oz. in a pailful of water 23. Easpbkrry Plume-moth {OxyptiUis nigrociliains,'zd\ei-)- In June another small caterpillar, somewhat like • the last, but with flner bristles and of a paler green colour, may be found injuring the foliage in a\-ery similar manner to the last. This, however turns to a very beautiful little moth, bronze, doUed with silvery white (Fig. 11), which may be flying about the canes in July.
