September. Extralimitally it extends to Philadelphia, and 
Ocean View, N. J., where it intergrades with a larger southern 
race. It frequents cat-tail marshes and sand-grass areas near 
the coast, and makes its presence known, especially where numer- 
ous, by the astounding racket it produces when stridulating, 
which has been admirably described by Scudder, "The song 
resembles that of the harvest-fly. Cicada canicularis. It often 
lasts for many minutes, and seems, at a distance, to be quite 
uniform; on a nearer approach, one can hear it swelling and 
decreasing in volume, while there is a corresponding muscular 
movement from the front of the abdomen backward, two and a 
half times a second. This is accompanied by a buzzing sound, 
quite audible near at hand; it resembles the humming of a bee, 
or the droning of a bagpipe." Rehn and Hebard speak of it as 
follows: "The song of this insect is a very loud and continuous 
buzzing which is very penetrating and usually audible to a dis- 
tance of at least 600 feet. This song is given loudly and persist- 
ently after dark; rarely lone individuals will be heard singing 
lustily even on clear days as early as four o'clock. During the 
day males sometimes at long intervals give a short hesitating 
and irregularly harsh note which would not be readily associated 
with their song. . . . This day song, or what might well be 
termed sleep-song, is in reality a brief and drowsy impulse giving 
just sufficient energy to the act of stridulation to demonstrate 
the sound produced when the vibrations are not at full speed, 
the irregularity of the sound resulting from the same cause. 
. . . While stridulating the males frequently rest head down- 
ward, occasionally moving nervously about without ceasing 
their song."
