Cabbage worm since it first began to spread oyer the 

 country and to play havoc with our cabbage fields, few, 

 if any, have given entire satisfaction. It is safe to say 

 that the most satisfactory remedy so far discovered is in 

 the use of Pyrethrum. Prof. Eiley was the first to 

 apply this in 1879, but did not care to recommend it 

 until further experiments had been made. He has made 

 these since, and caused others to be made by a number of 

 his agents and correspondents. The general experience 

 is most favorable, and he unhesitatingly recommends it for 

 all the different worms affecting the leaves of our 

 cabbage plants. Some have found hot water very ef- 

 fective on a large scale. Living plants will bear, without 

 injury, for a few seconds, water hot enough to kill soft- 

 bodied insects. The water should be at the temperature 

 of aboat 160° when it reaches the plant; it will cool 

 somewhat during the application, and allowance should 

 be made for this. 



THE WAYY-STEIPED FLEA-BEETLE. 

 {Haltica [Phyllotreta] striolata, Illiger.) 



*'The Striped Turnip-beetle (fig. 25, a,) is less than 

 one-tenth of an inch in length. Its general appearance 

 is black, with a broad wavy yellowish, or buff-colored 

 stripe, on each wing-cover. The 

 larva (fig. 25, b,) is white, with a 

 faint darkened or dusky median 

 line on the anterior half of the 

 body, being probably the contents 

 of the alimentary canal seen 

 through the semi-translucent skin. 

 The head is horny and light 

 brown. On the posterior extremity is a brown spot equal 

 to the head in size; and there are six true legs and one
