base. Pronotum with nearly parallel sides, being almost as broad pos- 

 teriorly as anteriorly, the disk plane, the front margin nearly straight, 

 the hind margin moderately convex, the lateral canthi distinct, the lateral 

 lobes being vertical or subvertical and rectangularly inserted in the disk, 

 slightly deeper than broad, the front margin vertical excepting below, 

 the lower margin and hind margin each strongly convex and subangulate, 

 the whole feebly margined. Tegmina about five times as long as broad, 

 somewhat opaque, the anal area moderately long, the principal vein 

 scarcely flexuous, the radial branch forked near the middle of its course, 

 the whole only a little surpassing the hind femora ; wings extending 

 considerably beyond tegmina. Fore femora armed beneath on the front 

 margin with 2-3 spines, the middle femora, which are much longer, 

 unarmed, the hind femora with 1-4 spines ou inner, 0-3 spines on outer 

 margin ; fore tibiae with 1-2 spines on outer margin above, 3-4 on either 

 margin below ; middle tibiaj spined on the posterior margin only above, 

 on both margins below. Anal segment of male rapidly and uniformly 

 tapering to slightly beyond the middle and then expanding into a some- 

 what decurved thickened apical portion, consisting of two lateral oval 

 everyw^here rounded lobes, scarcely tapering, apically bluntly rounded, 

 and separated by an equal or diverging interspace half as broad as the 

 middle portion of the segment and formed by a deep apical emargination ; 

 the whole is pale testaceous or castaneous, nearly or quite uniform, and is 

 broadest, when viewed from above, at the middle of the emargination. 

 Cerci of male subcylindrical, incurved and mesially bent, not very long, 

 moderately stout, and apically pointed. Subgenital plate of male 

 extending but very little if at all beyond the tip of the anal segment, 

 bent-arcuate, tapering and depressed in the basal half, subequal in the 

 apical half, compressed and emargiuate at tip, forming an arcuate V in 

 cross section. Ovipositor somewhat longer than the pronotum, not very 

 broad, bent-arcuate beyond the base, the tip rounded subacuminate, the 

 margins densely crenulato-dentate, the whole castaneous, the basal 

 plica luteous.
