This is a slender-bodied species with narrow tegmina and wings 
which usually surpass the hind knees by from 2 or 3 to even 6 or 
7 mm. The wings customarily exceed the tegmina 2 or 3 mm. 
Combined with the narrow thorax the effect of these characters 
is one of attenuation. The ovipositor usually about reaches the 
hind knees. 
The coloration is apparently affected by its salt-marsh habitat, 
often being more dusky and olivaceous than that of our other 
two species, with the sides of the pronotum a vivid bluish green.

Blatchley.) 
Above, a dusky stripe usually extends over the face and top of 
head, dividing into two on top of the pronotum, and is often pro- 
longed backward, suffusing the tegmina in the female or barely 
indicated about the speculum of the male. This duskiness 
increases rarely to such an extent as to approach melanism.
