saltatoria, those not adapted for jumping, and Saltatoria, the jumpers, 
with hind legs much thicker and longer than the middle pair.

1. Ischnoptera pennsylvamca (De Geer). — “Male: Pronotum ellip- 
tic, front border slightly narrower, its margin straight; the hind border 
rounded ; an oblique depression on each side, near the base. Tegmina 
membranaceous, more or less transparent, long and rather narrow, ex- 
tending much beyond the tip of the abdomen ; wings as long as tegmina. 
Sub-genital styles deflexed. 
“Female: Abdomen broader than thorax, its greatest width con- 
tained less than twice in its total length. Disk of pronotum a little 
convex, and with no impressions; its hind margin nearly truncate, the 
front margin narrower, rounded; the lateral margins somewhat flaring, 
their posterior third slightly upturned. Teymina broad, over-lapping, 
covering from a half to three-fourths of abdomen, their apices rounded; 
the veins prominent. Inner wings narrow, about half the length of the 
tegmina. 
“General color, chestnut brown to fuscous, the females the darker. 
Face reddish broAvn in center, the margins yellow. Disk of pronotum
