INDIRECT INJURIES CAUSED EY INSECTS. 203 



vented from coming to maturity a ; and a third (C Corrup- 

 ter, Host,) by a German, which seems closely allied to 

 Curculio Vastator, E. B., (C. picipes, F.) if it be not the 

 same insect. This destroys the young vines, often killing 

 them the first year; and is accounted so terrible an enemy 

 to them, that not only the animals but even their eggs are 

 searched for and destroyed, and to forward this work peo- 

 ple often call in the assistance of their neighbours 5 . — In 

 the Crimea the small caterpillar of a Procris or Zygaena, 

 (lepidopterous genera separated from Sphinx, L.) related 

 to P. Statices, F., is a still more destructive enemy. As 

 soon as the buds open in the spring, it eats its way into 

 them, especially the fruit buds, and devours the germ of 

 the grape. Two or three of these caterpillars will so in- 

 jure a vine, by creeping from one germ to another, that 

 it will bear no fruit nor produce a single regular shoot 

 the succeeding year c . — Vine leaves in France are also fre- 

 quently destroyed by the larva of a moth (Pyralis interna, 

 F.); in Germany another species does great injury to the 

 young bunches, preventing their expansion by the webs 

 in which it involves them d ; and a third (Pyralis Jhsciana, 

 F.) makes the grapes themselves its food : a similar insect 

 is alluded to in the threat contained in Deuteronomy e .—~ 

 The worst pest of the vine in this country is its Coccus 

 (C. Vitis, L.). This animal, which fortunately is not suffi- 

 ciently hardy to endure the common temperature of our 

 atmosphere, sometimes so abounds upon those that are 

 cultivated in stoves and greenhouses, that their stems
