294 STUDIES IN AMERICAN TETTIGONIIDAE (ORTHOPTERa) 



This name had been generally used by authors for texensis until 

 Scudder's revision of the genus in 1898, and the present species 

 was so recorded by Lugger in that year. 



Males of the present species are readily separated from other 

 species of the genus by the characters given in the key. Females, 

 however, might often be confused with females of S. curvicauda 

 were the differential characters not carefully studied. S. texensis 

 has a decidedly more glossy appearance than curvicauda and is a 

 more attenuate insect with the dorsum of the pronotum slen- 

 derer and the lateral angles usually weakly but appreciably 

 concavo-divergent caudad, these lateral angles are usually out- 

 lined in yellowish in the present species but frequent specimens 

 are found in which this marking is subobsolete or wholly absent. 

 The obscurity or absence of this marking is more often met with 

 in southern and western material than in series from the northern 

 Atlantic States. Females of texensis may be further separated 

 from those of curvicauda by the ovipositor which is more sharply 

 bent upward, more slender and armed with somewhat heavier 

 teeth than in that species.
