glossy, the fore pair opaque, yellowish at the tips, with a 

 black margin and band near the middle, and the abdomen 

 black, with three yellow bands situated one upon each 

 alternate segment ; width 0.65 to 0.85." 



Trocliilium caudatum. Harris. This species infests 

 our native wild Currant, (JRibea floridum^) and it reeem 

 bles somewhat the European species. 



To destroy these borers, the plants should be examined 

 every fall or during winter, and every shoot that has a 

 borer in it will usually be of a brown color, or slightly 

 wilted ; sometimes, when the shoots are very vigorous, no 

 difference can be observed, but by close inspection the 

 small hole where the worm entered can be found. All 

 phoots containing worms should be cut out, and the worm 

 destroyed. In this way they may be checked, if not en- 

 tirely eradicated. 



In making cuttings, the same care should be given, and 

 every hollow stem examined for borers, and if found, de- 

 rtroyed. 



fARIETIES. 

 NATIVE SPECIES. 



American Black. Ribea flvridum. Fruit medium, 

 roundish-ovoid, black ; clusters small, tapering. Seldom 

 cultivated, but worthy of it, if for no other purpose than 

 to produce new varieties, as it is naturally a better flavored 

 fruit than the European Black Currant. 



Deseret. JKibes aureum. Fruit very large, round, 

 black or dark violet, with a slight bloom, sub-acid and 

 agreeable flavor; flowers yellow; a strong and rapid 

 grower, and very productive when the plant attains its 

 fiill growth. A variety of the Missouri Currant (Ribe* 

 vureum). It is highly valued by the Mormons at Salt Lake 

 City, from whence I received it a few years since. Thii
