508 THE PHI[.AMPELUS. 



pillar is about an inch and a quarter in length, of a 

 blue color, transversely banded with deep orange 

 across the middle of each ring. The bands are 

 dotted with black ; the head and feet are orange. 

 They appear the middle of July, and the moths 

 which produce them the last of June (Harris). 



(10) Philampelus. This caterpillar is fully three 

 inches in length, and is a great consumer of the 

 foliage. Its color is pale green or brown. It has a 

 tail, curved like that of a dog, when it is young ; 

 but as it grows and changes its skin, this disappears. 

 It enters the earth during August, and, after being 

 transformed, comes forth as a moth early in the fol- 

 lowing summer. It is of so large a size that it can 

 readily be detected and destroyed (Harris). 



(11) Cfioerocampa vitis. This is a large, fleshy 

 caterpillar, like the preceding, feeding upon the 

 foliage. But the injury which it inflicts does not 

 stop here ; for it nips off the young bunches of 

 fruit and throws them upon the ground. It is for- 

 tunate that it is solitary, and that it does not in- 

 crease to such an extent as to ruin the whole crop 

 when half grown. It can be destroyed, like the 

 preceding, only by hand-plucking (Harris). 



(12) Rynchiiis vitis. This insect has been very 

 destructive to the vine in Europe, and in some parts 

 of the United States. It rolls up the leaves in form- 

 ing a retreat for its larva; and by this means a 

 whole vineyard is sometimes deprived of eflicient
