28 HORTICULTURIST'S RULE-BOOK. 



Egg-Plant. POTATO-BEETLE. See under POTATO. 



Elm. CANKER-WORM. See under APPLE. 



ELM LEAF-BEETLE (Galleruca xanthomelcena, Schr.). 

 A small beetle, imported from Europe, which causes 

 great devastation in some of the eastern States by eating 

 the green matter from elm leaves, causing the tree to ap- 

 pear as if scorched. 



Remedy. Arsenites with kerosene emulsion. 

 WILLOW- WORM. See under WILLOW. 



Endive. GREEN LETTUCE-WORM. See under LETTUCE. 



Flea-Beetle (Phyllotreta vittata, Fabr. ; Haltica striolata, 

 Harris). A minute black-spotted beetle, feeding upon 

 many plants, as turnip, cabbage, radish, mustard, potato, 

 strawberry, and stocks. It jumps upon being disturbed. 

 Closely related species attack various plants. Very de- 

 structive to plants which are just appearing above the sur- 

 face. 



Remedies. There are no reliable preventives or 

 remedies. Arsenites, applied dry while the dew is on, are 

 good. Land plaster, lime, ashes, and tobacco-dust, applied 

 in the same manner, are more or less effective. Tobacco 

 decoction used very liberally. Wood ashes applied liber- 

 ally. Sometimes ashes injure the plants. Kerosene 

 emulsion thrown with great force against the plants. 

 Calomel, mixed with flour or ashes. A heavy application 

 of Bordeaux mixture and soap is one of the best repellents. 

 The same remedies apply to other flea-beetles. 



Four-striped Plant-Bug (Pcecilocapsus lineatus, Fabr.). A 

 bright yellow, black-striped bug about one-third of an inch 

 long, puncturing the young leaves and shoots of many 

 plants. 



Remedies. Jarring at any time of day into a dish of 

 dilute kerosene. Kerosene emulsion (2) (diluted five 

 times) when the bugs are young, in their nymphal stage. 

 Cut off and burn the tips of the growing shoots in early 

 spring to destroy the eggs. 



Galls. See KOOT-GALL (page 41).
