198 SMALL FRUIT CFLTUKIST. 



Another worm is shown suspended from the edge of the 

 leaf, as they appear when letting themselves down to the 

 ground ; while below it is the pupa, in which form the 

 worm remains in the ground during winter. The worms 

 are about an inch long, of a lively yellow color, covered 

 with small black dots. English gardeners recommend 

 dusting the plants and worms with powdered white helle- 

 bore. This remedy has been used in this country with 

 good effect. 



There are several other worms injurious to the Currant, 

 because they feed upon the leaves ; but their numbers are so 

 few that they have not, up to the present time, caused 

 any considerable injury. 



There is, however, another class of insects that attacks 

 the stems and does considerable damage. Among the most 

 destructive of these are what is called the Currant Borers. 



There are several species ; the following three are the 

 best known : 



Prenocerus SUpernotatllS. American Currant Borer. 

 " This is a small, cylindrical, white worm, destitute of feet, 

 and with a small, chestnut-brown head, and black jaws, 

 passing its pupa state in the stalks, and, the latter part 

 of May changing to a small, slender, long-horned beetle, 

 of a black color, edged with chestnut brown; its wing 

 covers each with two, small, gray spots forward of their 

 middle, and a white crescent -shaped one towards their 

 tips." Fitch. 



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
