Field Guide to Grasshoppers, Katydids, and Crickets of the United States

A large, green species, with olive-green forewings and usually a pale-yellow dorsal stripe extending from the front of the head to the tip of the forewings. Occasionally females lack the stripe or bear indistinct brownish spots on the forewings. Hind tibiae are blackish purple with yellow, black-tipped spines. Males are 36-45 mm long, females 50-65 mm.

In males, the supra-anal plate lacks a pair of small tubercules near the center. The tips of the subgenital plate are flared outward. The cerci are highly bilobed, with the lower lobe protruding more than the upper lobe (similar to those of S. alutacea).
