Allied to S. venusta and S. lietrnxjamhi Sanssure and Zehntner," 

 but differing from both in the much oreater size, the denticulate mar- 

 gins of the pronotum. and in the absence of fuscous maculations on 

 the tegmina and wings. 



Size rather large; form elongate and slender. Head considerably 

 broader than deep; eyes ovoid when viewed laterally; facial shield 

 strongly transverse, obtuse angulate; ocelli closely placed; antemia? 

 extending somewhat beyond the posterior margin of the pronotum. 

 Pronotum with the collar broader than any portion of the shaft, the 

 latter strongly compressed centrally, the longitudinal median carina 

 faint and not visible on the posterior third; supracoxal dilations not 

 strongly marked; margins of the collar, lobes, and anterior half of the 

 shaft with well-marked denticles. Tegmina transparent, elongate, 

 slightl}' exceeding the abdomen in length; sutural and costal margins 

 subparallel, apex subangulate; costal field comparatively wide, of 

 appreciable width for about half the length of the tegmina, surface 

 sparsely and irregularly reticulate; stigma transparent and hardly 

 visible. Wings elongate, slightly exceeding the tegmina in length 

 when in repose, transparent. Abdomen elongate, slender, very con- 

 siderably depressed. Supra-anal plate small, triangular, ai)ex rounded. 

 Cerei exceeding the subgenital plate in length, very strongly depressed; 

 apex rather Idunt. Subgenital plate rather large, triangularly pro- 

 duced; apex narrowly truncate and supi)lied with two very minute, 

 snnple styles. Anterior coxa^ supplied with five or six large denti- 

 form spines on the lower margin; femora rather slender, exceeding 

 the coxa> by over one-fourth of their length, external margin bearing- 

 four large spines, discoidal spines four in number; apical half of the 

 internal margin bearing a continuous row of alternating large and 

 small spines; ti))ia' about equal to half the length of the femora, spines
