A certain amount of geographic variation is found in this species, 

 both in size and in coloration,-"'* but very decided indivichia! varia- 

 tion in both these features also occurs. 



Coloration. — cf. (Recessive.) (Normal in eastern material; 4 

 cf, St. Louis, Missouri; i cf, Baton Rouge, Louisiana.) Head 

 with occiput tawny, shading to chestnut brown between the eyes 

 and fading to tawny below the ocelli ; genae and clypeus ochraceous- 

 buff. Ventral surface of body laterad chestnut brown, shading to 

 hazel mesad on alxlomen. Limbs ochraceous-ljuft". Pronotum 

 with disk clear ochraceous-tawny, with margin narrowly 

 ochraceous-buff cephalad, more broadly laterad, the caudal por- 

 tions of the lateral margins transparent. Tegmina transparent, 

 weak ochraceous-tawny. Wings hyaline, very feebly tinged with 

 ochraceous-buff, area of costal veins washed with ochraceous-tawny.

2°* Specimens from the CaroHnas, from the Piedmont to the coast, average ver>' large.
