tember and early October. It is much less common near Boston 
than its round-winged relative, but is recorded from Seabrook, 
N. H., several points near Boston, Connecticut, Montreal, south- 
ward to New Orleans, and westward to Colorado and Texas. 
According to Allard, its stridulation "consists of a single brief 
phrase repeated at more or less regular intervals. When heard 
close by, it is apparent that this note begins with a very rapid 
crepitation, which may be likened to the sudden rasping of an 
object across the teeth of a comb. This terminates sharply with 
a sound remotely like 'itzic' The entire song may be likened to 
the syllables, z-z-z-z-itzic."

This is a medium-sized member of the genus with tegmina and 
wings proportionally shorter than in the Oblong- winged Katydid. 
Half a dozen examples are recorded by Rehn and Hebard from 
Nantucket and Woods Hole, Mass., and it will probably be found 
in southern Connecticut. Extralimitally it extends to Georgia, 
and another subspecies, from which this is distinguished by having 
more pronounced lateral angles on the disk of the pronotum, to 
Florida and Texas.
