base of the tufted growth of grasses amid which they live. Here 
also the eggs are deposited, the ovipositor being thrust down 
between the sheath and stem of a coarse grass, such as Andro- 
pogon. Their stridulating powers make them well worth seeking 
out, one species in particular, common coastwise, being notable 
for the strident, piercing quality of its song, which renders it 
audible at a long distance. Four species inhabit New England, 
and adventive examples of another are occasionally introduced 
with garden truck.
