the rear. But when the katydid "cleans up," it does a thorough job. It 



nibbles its front feet, paying special attention 

 to the pads, meanwhile holding the foot to its 

 mandibles with the aid of the palpi. But once 

 washing is not enough; I have seen a katydid 

 go over the same foot a dozen times in succes- 

 sion, beginning always with the hind spurs of 

 the tibia and nibbling along the tarsus to the 

 claws. It cleans its face with its front foot, 

 drawing it downward over the eye and then 

 licking it clean. It cleans its antenna with 

 its mandibles by beginning at the base and drawing it up in a loop as fast 

 as finished. After watching the process of these lengthy ablutions, we 

 must conclude that the katydid is among the most fastidious members of 

 the insect "four hundred."
