sinuate, and apex acute; from above the sides are nearly straight 
and the apex blunt, convex. Cerci four times as long as middle 
breadth, nearly straight, tapering on basal third, the distal two- 
thirds nearly equal in width, ending in a broad, rounded tip 
which is a little more produced on the ventral side and often some- 
what flattened and even grooved, the whole organ very slightly 
incurved. Furcula reduced to a pair of minute, widely separated 
tubercles. Ovipositor of female exserted, large, but upper valves 
lacking angulation at base of scoop. 
Color: usually a dark rufous brown above, paling to light red 
toward end of tegmina. Hind femora conspicuously banded with 
fuscous at base, apex, and thirds. Hind tibiae bright cherry red 
throughout, or more or less yellowish or even glaucous at base. 
Lateral black stripe usually distinct, sometimes nearly obsolete, 
often cut obliquely on prozone by a pale line. Beneath pale 
yellowish white or gray. The ground color above sometimes 
varies to ivory white on head, pronotum, dorsal field of tegmina, 
and hind femora, producing a conspicuously variegated or 
banded pattern. This color variety occurs usually in near 
proximity to open sand areas. I have taken examples of it at 
Orono, Me., and Provincetown, Sudbury, and West Chop, Mass.

This species is usually recognized at once, the cerci of the male 
being quite distinct from those of any other of our species, and 
the typical female may be known by the length and attenuated 
form of the abbreviated tegmina. In the case of the long- 
winged female and specimens causing doubt, the heavily fasciate 
femora, the decidedly transverse metasternal interspace, and 
the prosternal spine — broad at base, conical, with rounded apex, — • 
should remove any uncertainty. 
This is a very widely distributed species, from Newfoundland 
and Labrador southward to the mountains of Alabama and west- 
ward to Arkansas, Colorado, Alberta, and Washington. Partly
