females usually leap for the first two or three times they are 
disturbed, but if flushed a number of times they use the wings in 
endeavoring to escape." 
It is one of the late-maturing species, first appearing in the 
winged state in late July or about the first of August and flying 
until the frosts and snow of November put an end to its existence. 
While it inhabits all of the New England States, it is probably 
absent from their more boreal portions and becomes really 
abundant only in the warmer districts. It is known from Orono, 
Norway, Fryeburg, and Deering, Me.; Jackson, Hanover, and 
Kingston, N. H.; Brattleboro, Vt.; and many localities in Con- 
necticut and Massachusetts, including Edgartown on Martha's 
Vineyard.

Body small for an Oedipodine, a little compressed. Head of 
moderate size, face somewhat retreating, facial costa rather 
prominent above, scutellum of vertex moderately deep. Disk of 
pronotum truncate anteriorly, obtuse-angled behind, flat, the 
lateral carinae continuous, nearly straight, the sulci shallow. 
Median carina low, keel-like, slightly arched on prozone, hori- 
zontal on metazone. 
Color: in general, pale buffy white or dead-grass color, varied 
with dark brown or fuscous above and on sides. Wings trans- 
parent with smoky veins. 
Head pale, darker above, a triangular fuscous spot behind eye 
and a band running forward from lateral ocelli to facial costa. 
Pronotum brown above, sometimes paler on disk along lateral 
carinae, the prozone chiefly black from lateral carinae nearly to 
lower margin; sides of metazone pale. A collared form has been 
noted in Minnesota.
