and while this is still hot, the kerosene and the re- 

 maining- water are added. 



Poisonous arsenious sprays may also be used, but 

 where this is done, all stock must be kept out of 

 paddocks for a week or two.

2. — Long-horned Grasshoppers. 

 Family Phasgonuridae. 



(Plate 7, Figs. 3, 4, and 5.) 



(Usually referred to in text books as the 

 Locustidse. ) 



It would perhaps be more correct to call these 

 treehoppers, as they are found, not on the grass, 

 but on the foliage of trees. In American writings 

 they are known by the popular name of katydids, 

 because their chirping noise seems somewhat to 

 resemble this word. 



They may be distinguished from the short-horned 

 grasshopper by the following distinctive features: 



(a) Exceedingly long antennae, more than 30 

 joints, and often extending far beyond the 

 body. (Plate 7, Fig. 4, a.) 



(b) The organ of hearing is not situated on the 

 abdomen, but on the tibia of the first pair 



' of legs. (Plate 3, Fig. 6, a.) 



(c) The ovipositor is prominent and spear- 

 shaped. (Plate 3, Fig. 8 a.) 



(d) The tarsus is 4 jointed.
