A paratypic female was also examined (August). The color of this 

 specimen differs from the type in that it is more brownish, and the 

 caudal femora are distinctly barred dorsad.

Chapada, Matto Grosso, Brazil. April, August, and 8eptember. 

 (H. H. Smith.) [U.S.N.M.] Five males and two females. 



This exceedingly variable species is represented by individuals of 

 all the three color phases so well described by Giglio-Tos. Type "a," 

 with distinctly marked median and lateral pronotal carinas and con- 

 trasted coloration, is represented by two males; type "b," with the 

 dorsal surface uniform, but with the pronotal cross moderately dis- 

 tinct and the caudal femora barred, is represented by two females; 

 type "c," which is quite uniformly colored without dorsal cross, 

 restricted tegminal maculations and incomplete femoral bars, is 

 represented by three males. 



This species has been recorded from Paraguay, Caiza, southern 

 Bolivia, and Colon. The latter record, although made by the de- 

 scriber, " appears rather doubtful.

Allied to S. picfa and conspersa on one hand and /iS. 'varipes and 

 smithi on the other. From picta it can be readil}^ separated by the 

 slender build, while conspersa has shorter tegmina, less constricted 



'I lateral pronotal carinae, broader frontal costa, and less distinct lat- 

 eral foveolge. Yvovc\.varipefi it can be distinguished by the more arcu- 

 ate and less retreating face, the distinct lateral foveolae, the more arcu- 

 ate caudal margin of the pronotum, the somewhat less compressed
