206 SMALL FRUIT CULTUKIST. 



of this order that injure our garden plants, but the one 

 under consideration is an exception to the general rule. 

 It first appearance in this country was about 1857, and in 

 the vicinity of Rochester, N. Y., and is supposed to have 

 been introduced with imported plants. 



The flies come out of the ground early in spring, and 

 the females soon commence depositing their eggs on the 

 underside of the leaves near the veins. The eggs hatch 

 in about a week, and immediately commence feeding upon 

 the soft part of the leaves. At each moult they change

 black spots scattered along the sides and on the back. 

 "When mature, they drop to the ground and hide under

 first one, unless checked or destroyed by application of 

 hellebore or similar insecticides. Hellebore is usually 

 applied while the fruit is green, and any that may remain 

 upon the fruit is washed off by the rain ; should any ad-

The Native Cnrrant Worm, This is a closely allied in- 

 sect to the last, belonging to the same order and family, 

 but to another genus. It is the Pristiphora grossularice, 

 Walsh. Its habits are also similar to the imported worm, 

 and it may be destroyed with similar insecticides. 



Trochilium tipuliforme. European Currant Borer. 

 This is quite common in the Eastern States, and we seldom 

 receive Currant bushes from Europe that do not contain 

 more or less of these pests. It is too well known to re- 

 quire a description. The moth is probably not so familiar, 

 and I give the description given it by Dr. Fitch, in the New 

 York Agricultural Report, 1859: "A small moth, having 

 some resemblance to a wasp, its wings being clear and
