The leaves of the bushes should be examined during the last week of May, and as only a few leaves are affected at first, these can be detected by the pres- ence of the eggs and the little round holes in them, and should be plucked off and burnt. The female saw fly is bright honey-yellow, with the head black, but yellow F. „ below the insertion of the an- tennae. The male differs in its black thorax, and the antennae are paler reddish than in the ; The dates given above of the times of appearance of the two broods will apply to this state. The natural enemies of this pest are three ichneumon flies, one of which is a minute egg- parasite, Mr. Lintner of New York, stating that among fifty eggs only four or five hatched out the currant worm. One of the best remedies, next to hand-picking, is dusting powered white hellebore over the bushes, by sprinkling it from a muslin bag tied to a stick, as it otherwise excites violent sneezing. Used in this small quantity it is not poisonous. Dr. Mack tells me that he has used a solution of a pound of copperas to six gallons of water with much success. It blackens the leaves, but does not injure them permanently. By steady and combined effort this terrible pest, together with the currant looper or geometer, Abraxas ribearia, can be kept under. Birds and fowl do not apparently feed on this worm, as our feathered friends have their antipathies to certain articles of worm diet, hence we must fight them with fingers and drugs.
