in length to the body and equals or slightly exceeds the length 

 of the hind femora. Tegmina of the common short-winged 

 form covering about two-thirds of the abdomen in the female; 

 usually reaching its tip in the male. Hind femora usually 

 unarmed, though sometimes bearing one to four small teeth on 

 their lower outer carina. Cerci of male rather stout, with the 

 apical half curved slightly outward and depressed. Ovipositor 

 slender, straight. The general color is more of a green than in 

 brevipenne; the face, sides of pronotum and abdomen, and usually 

 the four anterior femora being of that hue. The tegmina and 

 wings are light reddish brown, as are also the tibiae and ovi- 

 positor."*

Closely resembling Xiphidium, but of larger size. Spines of
