Of large size and robust form. Pronotum broad, prozone of 
female full. Mid-carina in both sexes indistinct on prozone, 
distinct on metazone. Tegmina somewhat variable (see meas- 
urements). Hind femora long and strong. Hind tibiae stout. 
Subgenital plate conical, apex rounded, a little elevated, its dorsal 
margin thickened posteriorly. Cerci roughly sock-shaped, large 
flat plates two and one-half times as long as basal width. Furcula 
reduced to short flattened tubercles from tumid bases. 
Color: quite different from that of all of our other species, lack- 
ing any maculation. Dull olive brown to greenish yellow above, 
yellow or yellowish green beneath. Usually with a distinct pale 
stripe on each side of crown of head, continued backward along 
inner side of position of lateral carinae of pronotum and outer 
edge of dorsal field of tegmina. Oblique pale stripe on metepi- 
sternum distinct, wide. Lateral stripe of pronotum occasionally 
distinct but usually weak and faint. Hind femora often with 
indistinct or incomplete dusky transverse fasciae, which are some- 
times strongly marked on the dorsal face. Knees, and ring below 
them, often partly or wholly black. The prevailing olive tint is 
sometimes replaced by a yellowish or rufous tinge throughout. 
Specimens dried without preparation become a very dingy brown
