the eyes; antennae uniform in coloration. Pronotum short with nearly 

 parallel lateral angles rounding everywhere evenly (and more broadly than 

 in other species of the genus except *S. strigata) into the lateral lobes which 

 are distinctly deeper than long, cephalic margin of lateral lobes very broadly 

 rounded, passing through the ventro-cephalic angle into the oblique, nearly 

 straight caudal margin, humeral sinus shallower than in the other species 

 of the genus. Tegmina shining, similar to those of paronae but propor- 

 tionately narrower with transverse veinlets sub-obsolete and the entire 

 surface an intricate network of minute veinlets; wings as in paronae. 

 Supra-anal plate with proximal width greater than length, triangularly 

 produced with lateral margins weakly concave and apex bifid, V-emargi- 

 nate. This apex when seen from below is found to be made up ventrad 

 of two lateral perpendicular folds with crassate margins which curve 

 out and around the tips of the incurved cerci ventro-proximad and then 

 join mesad on the ventral surface of the plate; near the very apex of 

 these folds distad spring out from their sides small strongly compressed 

 vertical lateral flanges which are triangular withapex rounded, these 

 would if brought in contact with the subgenital plate embrace the same. 

 Cerci nearly intermediate between the type found in S. septentrionalis 

 and the normal type found in the genus; crassate, becoming evenly and very 

 weakly more attenuate with a slight arcuation to apex, which is suddenly 

 bent inward and armed with a sharp black tooth directed at a right angle 

 to the distal portion of the cereal shaft. Subgenital plate depressed 

 throughout, acute-angulate emarginate distad to a depth about one-half the 

 distal width of the plate. Cephalic and median limbs similar to those of 

 paronae, caudal limbs shorter and more robust than in that species. Cau- 

 dal femora distinctive in having both ventral margins armed with small 

 teeth (not spines), caudal tibiae with all four margins thickly supilied with 

 heavy spines. 



Allotype. — 9 ; same data as the type. 



Description of Allotype. — Very similar to type but larger with propor- 

 tionately broader tegmina. Ovipositor gently arcuate, not at all bent, long 

 and broad to the immediate apex which is more suddenly rounded than in 

 the other species of the genus, distal half of dorsal valves and extreme 

 distal portion of ventral valves margined with small, even and rounded 

 teeth. Subgenital plate triangular with truncate apex, this plate unusually 

 short for the genus, not extending to the juncture of the ventral valves of 

 the ovipositor. Limbs and armament of same as in the type.
