 delicate in its nature, is destroyed with the most gen- 

 tle touch. The brush also most readily wipes off 

 the web, as well as the globular transparent eggs, 

 which are, by a fine membrane, fastened to the 

 leaves ; and thus we are secured from the danger of 

 a succeeding brood. This process may, to some, 

 have the appearance of a tedious operation ; and, in- 

 deed, when vines are injudiciously trained, it certainly 

 must be attended with great trouble ; but it is very 

 easily performed upon vines trained in the regular 

 method here set forth, and a single operation is gene- 

 rally sufficient for a whole season. (Speechley, 175.) 

 Aphis vitis, the Louse, Puceron, or Vine Fretter, 

 sometimes appears upon the young shoots of the vine, 

 but these grow so rapidly that we never observed any 

 injury caused to them by this insect. It is speedily 

 destroyed by tobacco fumigation. 



Coccus vitis. — The vine scale preys upon the stems 

 and branches of the grape vine, both in the open air 

 and under glass. It seems to be the same species 

 which also attacks occasionally the peach, nectarine, 

 and plum. It is, says Mr. Curtis, a longish brown 

 insect, which in old age assumes a blackish brown 

 colour, and becomes hemispherical and wrinkled. 

 The females are shield-like, being convex above and 

 flat or concave below ; they are furnished with six 

 small legs, which, when the insect is old, become part
