falling in intensity, often ceasing as from exhaustion. The num- 
ber of consecutive times without pause that this sound was pro- 
duced were on one occasion counted, 26-14-20-20-17; usually on 
a warm evening an undisturbed singer would average about as 
above before ceasing for a few seconds. The song is rapid, the 
sounds being emitted on warm evenings about three to the second. 
When near a colony of this species on favorable evenings after 
dark the air is vibrant with the sound; as several singers cease 
others take up the constantly rising and falling song, but at no 
very great distance the sound is inaudible. The insects were 
found not to begin to sing until nearly sunset and before dark 
often ceased their song upon any attempt to approach the spot; 
after dark the singing was much more vigorous and the singers 
could then often be approached with a light and cautiously seized 
while singing and moving about in the bushy weeds and heavy 
grasses into which they climbed while stridulating " (Rehn and

Males average a little smaller. 
This is a large, robust species with very blunt vertex margined 
with dusky beneath. The ovipositor is about equal to the hind 
femora in length, straight, much exceeded by the closed tegmina. 
The head and pronotum are exceptionally broad and heavily 
built. 
This is a southern species, of purely adventitious occurrence 
in New England, two examples of which have been captured here 
in the winter season, one at West Newton, Mass., March 11, 
1898, in a dw^elling-house, alive, in spinach greens (H. W. Burri- 
son) ; the other at Danvers, Mass., January, 1916 (L. W. Jenkins), 
likewise in a house, doubtless having been introduced with similar 
material. Its habitat is from southern New Jersey and Washing- 
ton, D. C, to Florida, Texas, and across the continent to southern 
California.
