conical, with a blunt point in the female, more acute in male. 
Tegmina distinctly tapering. Hind femora stout and rather 
short. Subgenital plate with dorsal margin ampliate at base, 
the apex truncate, the hind margin thickened. Cerci with a 
broad, tapering base and furcate distally, the upper branch 
longer, two-thirds as long as the base 9,nd about half as wide; 
the lower branch acutely pointed, usually but little deflected 
from axis of base, the upper distinctly deflected upward and a 
little inward, sulcate near its lower margin, its apex rounded 
and a little more drawn out on the lower side. Furcula absent 
or reduced to tiny, well-separated tubercles. Ovipositor little 
exserted but the tips of the valves long and very acutely pointed, 
little recurved, the dorsal valves with the outer edge of the 
basal half of the scoop crenulate or denticulate. 
Color: dusky brown above, ranging from rufous to olivaceous, 
sometimes ferruginous, bright rose, or carmine on head and 
pronotum; beneath yellow or yellowish green. Lateral stripe 
usually distinct only in male on prozone and sometimes wanting 
there. Sides of thorax dusky, crossed by conspicuous dusky 
pale bar. Tegmina almost invariably marked with fine dusky 
flecks. Hind femora fasciate with dusky above, clear yellow 
beneath. Hind tibiae bright red throughout with black spines 
and pale pubescence, lacking distinct pale or duskj'- annulus at

This is one of our later-maturing species: adults appear in 
late July and August and remain active until the heavy frosts or 
snow of approaching winter put an end to their existence. One 
may meet with it almost anywhere, but it is partial to the semi- 
sylvan conditions furnished by open groves and the edges of 
deciduous woodlands, especially on rather dry upland soil. 
It is more sluggish than the Red-legged or Lesser Migratory- 
Locusts, and with its stocky body and usually dull coloring is a 
less attractive and interesting species. The males, however, are 
sometimes very brightly colored and under the rays of the mid- 
day sun show a considerable degree of sprightliness. In late
