CABBAGE. 153 



12. The Tarnished Plant-bug (Capsus oUineatm). 



13. The False Chinch-Bug (Nysius destructor.) 



FLEA-BEETLE. 



The first in order to attack the plant in its earliest 

 growth, and before the appearance of rough leaves, is the 

 Flea-beetle in the perfect state. Lime or soot, dusted on 

 the young plants, while wet with dew, seems distasteful 

 enough to the insect to drive it off. The larva also in- 

 jures the roots of larger cabbage plants. ' 



12-SPOTTED SQUASH-BEETLE. -

 North. The "Club-root," a warty enlargement of the 

 roots, has been ascribed to this insect, but I have never 

 seen it at the South. The Cabbage Maggot had not 

 been observed to be injurious to the crop until after the 

 publication of the first edition of this book, but since 

 then it has become the most destructive of the many in- 

 sect pests of the cabbage, ruining large fields in South 

 Carolina during the spring of 1885, and in Georgia dur- 

 ing that of 1886 so completely, that farmers plowed them 

 up for other crops. When a plant shows signs of the 

 presence of the insect by a sickly appearance, it is already 

 past remedy. The fly deposits its egg on the plant at or
