The song is a continous trill, much like that of the Four-spotted 
Tree-cricket, a little higher in pitch, and often seems to possess 
more volume and intensity. It is frequently given in the after- 
noon as well as at night. 
The distribution of this Tree-cricket coincides with that of the 
Four-spotted. It has been taken at Brunswick and Hoxie, Me.; 
Franconia, N. H.; Wood- 
stock, Vt.; and at many 
points in southern New 
England.
