3. The JFeevii. 



The satin greeu vveevil, Rhynr.ites Bacchus, is small aud generally 

 found in pairs. It settles on the young cluster, pierces the foot-stalk, 

 takes possession of a leaf, curls it and deposits its eggs in it, ag- 

 glutinated to it bv some viscous matter. These eggs are about the 

 size of a small pin's head and of a yellowish white. The larva is 

 hatched in a fortnight ; it is without feet, six lines long, white, smooth 

 and with a yellow head. It first feeds upon the leaf in which it 

 was hatched : and grubs in the gromid or imder dung during winter, 

 until its metamorphosis in the spring. 



There are some seasons in which the Rhyncitcs ruhens is so plenty, 

 that it pricks the forward grapes and sucks them, and rolls almost 

 every leaf, which is a great injury, as the leaves are renewed at 

 the expense of the fruit, and the bunch, deprived of its nourishment 

 and support, wastes, wilts, and comes to nothing. The curled leaves, 

 nets, purses &c. in which the eggs are deposited, must be clipped off 

 and carefully carried to a distance from houses, woods, hedges &c. 

 and there burned ;. and about the close of the winter, the manure, if 

 any, around the root of the Vine, must be raised and set fire to; as 

 it is the place of refuge not only to this, but many other grubs. This 

 measure will make a pretty thorough clearance. 



Another weevil called the grey weevil is highly destructive in the 

 South. It attacks the sprouts just as they begin to unfold and pre- 

 vents then- full developement. In the departments of Aube, Gard 

 and Haute-Garonne, they use against it the usual precautions against 

 catterpillars in general. 



4 The red Chrysomela. 



This insect, the Chrysomela lucida of Linnceus, feeds on the Vine 

 leaf, but the injm-ies it occasions are so small as to escape notice 

 except in seasons when they are uncommonly numerous ; but even 

 then, they are nothing to be compared to the ravages of those already 

 mentioned- 



5. T]te CocclncUa glolosa. 



The larvae of this insect, commonly called lady-bug, eat the Vine- 

 ieaves, but they will also, it is said, destroy Aphides ; they are 

 sometimes so numerous as to cover the stems ; they have a horny 

 head, a naked body and tail, annular; with six feet.
