There appear to be two or more broods each season. REMEDIES y A large number of substances have been recommended as preventives of flea-beetle attack, success in the use of any of which depends, to a great extent, upon the comparative abun- dance of tlie insects. Our own experiments indicate that the pests may be driven off from garden vegetables, in early Spring, by the liberal application of simple repellant and deterrent substances like plaster, air-slaked lime, soot, and especially tobacco powder, dusted on when the plants are wet with dew. I obtained more satisfactory results, however, b}' the use of a spray of lime wash made by adding a pint or more of freshly slaked lime to two gallons of water, and then thoroughly mix- ing in about half a teaspoonful of Paris green. I sprayed this upon a variety of garden crops with excellent results. The lime dries on in a firmer coating than when simply dusted ou, and consequently is more effective. A still more certain remedy is found in the use of the Bor- * Phyllotreta Please note that these imag
