40 Allard — The Strldulations of some " Katydids.^' 



bles of a few seconds duration, usually from three to five 

 following in rapid succession, with intervals of rest — kitzy- 

 kitzy-kitzy-kitzy-kitzy — or kitzy-kitzy-kitzy. In the high forest 

 trees throughout the little settlement of Thompson's Mills, Ga., 

 the strident calls of this katydid may be heard above all other 

 insects. Here, on warm, summer evenings, the quiet dusk is 

 suddenly interrupted by the incisive notes of a single singer, 

 and the din of the entire colony immediately starts up to con- 

 tinue throughout the night. It is also a noisy species in the 

 trees on Plummer's Island, Maryland. 



The stridulations of nearly all the katydids are harsh and 

 unmusical reiterations, yet their lively notes add greatly to the 

 life and buoyancy' of the midsummer days and nights.
