Georgia, south and east as far as Warm Springs and Macon, Georgia, 

 and Yemassee, South Carolina. The material shows a great amount 

 of individual variation in size, both sexes exhibiting this in material 

 from the same locality, collected in the same environment. Certain 

 individuals, particularly of the female sex, show a general lightening 

 of the entire coloration, while very rarely (one adult and certain 

 nymphs) the pronotum is washed with pinkish. The adult male 

 from Augusta is very pale and quite ochraceous, with the dorsal 

 femoral markings very decided, solid and regular. These markings 

 vary appreciably in individuals of relatively the same color depth. 

 There is some variation in both sexes in the form of the tegmina, the 

 distal section being more rounded and less subangulate in certain 

 specimens than in others. 



From the available evidence we find that the species occurs adult 

 as early as July 25 (Blue Ridge, Georgia; Morse) and as late as 

 October 7 (Sulphur Springs, North Carolina; Rehn & Hebard), few 

 adults having appeared as late as August 4 (Toccoa). 



This form is always sylvan in habitat, occurring on the ground 

 under oaks and in mixed oak and pine woods. On one occasion it was 

 found about low scrub oak scattered over a sandy area (Augusta).

From a study of the material before us from the eastern and 

 southeastern States, it is evident that southwards both sexes show a 

 gradual broadening of the tegmina and rounding of the distal margin 

 of the same. This feature is similar to that found in the Texan 

 form, scudderi texensis Hart, of which we have typical material, but 

 that race also has the general form more compressed in both sexes, 

 the furcula longer, the subgenital plate less produced and some feat- 

 ures of the coloration different. The relationship of the material
