more than three or iour inches above the ground when jump- 

 in^-, la this respect it dilTers grcatl}- from our North American 

 destrtictive locust and the majority of native grasshoppers 

 both here and there. These latter very frequentl}^ spiing several 

 feet into the air. In I'act our locust is not built for jumping, 

 as an examination ot its comparativeh' small and slender hind 

 legs will show. Like the Wandering Locust of the Old World, 

 the Argentine destructive locust is not particularly noted as 

 a jumper ; but when it comes to Hying they are "right at home." 

 On account of its non-jumping proclivities it has been necessary 

 in the selection of remedies to discard several of the very best 

 methods of destroying other larval locusts. Still, on account 

 of its tendency' towards bunching at all times it is one of the 

 easiest of all locusts to fight. All that is required is the adoption 

 of remedies that will conform to its habits, and then go to 

 work and keep at it. 



When marching the saltonas are like sheep. Where one or 

 more lead all try to follow ; and Avhen once a manga gets to 

 moving in a certain direction it is no easy matter to change 

 its course. This trait in the insect renders it a comparatively 

 easy one to trap in boxes, pits and ditches. Then too, their 

 claws on the middle and front feet are short and ^veak so they 

 cannot take hold of hard and smooth surfaces. This also 

 renders their capture more easy since when once tallen they 

 can neither crawl nor jump out. 



In their food-habits the saltonas dilfer but little from what 

 has already been said regarding the voladoras. Only a few 

 plants that are not molested by them are Inter attacked b}' the 

 winged insects. It has also been observed that a few plants 

 which are passed by when the insects are quite small are 

 attacked by them when they are older and larger. It is also a 

 fact that the insects feed on some plants ^vhich are young and 

 tender, but not when older and tough, and vice-versa. 



As with the voladoras, the saltonas seen quite panic-striken 

 under certain conditions. The approach of a pampero or other 

 storm causes them to crawl under the grass, weeds, and other 

 vegetation, where they hang fast as if in despair of their lives. 

 When being driven, too, they often exhibit the same kind of 

 fear and hide in like manner. But this latter onh' occurs when 

 they are rushed and become confused. It also sometimes hap- 

 pens that where a iield has been gone over day after day
