Geographic Variation: — Under this heading we have several 

 features which need consideration. The species seems to be in 

 process of breaking up into at least two forms, which, however, 

 are not fixed enough to recognize by name and which are not 

 quite absolute in their geographic correlation. One is a heavier, 

 stockier type, with a generally more flaring caudal margin of the 

 pronotum when seen from the side, relatively more robust 

 caudal femora and heavier and straighter, although sometimes 

 faintly arcuate, ovipositor. This type is that of the mountains of 

 New York and portions of Pennsylvania, as well as Ohio, Indiana 

 and Iowa. The other is a relatively more slender type without as 

 much flare to the pronotum, relatively less robust caudal femora 

 and more slender ovipositor, which latter generally has a slight 

 decurvature of the ventral margin and a distinctly ventral apex.
