A brief description is given of the fall army worm [Laphygma 

 Jrugiperda] and its life-history. 



The remedial measures advocated are the use of poison-baits, 

 sprays or dust. The poison-bait, which should be made fresh each 

 day, consists of 20 lb. of bran, 5 lb. of cottonseed meal and 1 lb. of 

 Paris green mixed with 3 or 4 finely chopped lemons and 2| U.S. gals, 

 of water to which 2 U.S. qts. of molasses or s}T:up should be added, 

 the whole being well mixed to a consistency which will fall in fine 

 flakes when scattered. Oranges or grapefruit may be used, but lemons 

 or limes are preferable. Additional bran may also be substituted 

 for the cottonseed meal. This quantity is sufficient for 4 to 5 acres. 

 The sprays recommended are 1 lb. of Paris green, 2 lb. of lime and 

 150 U.S. gals, of water, or 3 or 4 lb. of lead arsenate paste to 100 U.S. 

 gals, of water. Half this quantity will be required if the powdered 

 form is used. A% a dusting powder 1 lb. of Paris green may be used 

 with 50 lb. of flour or lime.
