green, through sea-foam, green and antimony yellow and ochraceous- 

 buff to pale tawny and even (very rarely) hays russet, the dorsum 

 rarely with a ferruginous wash. The postocular bars in both 

 sexes range from deep blackish fuscous to prout's brown, usually, 

 but not invariably, more contrasted in the male than in the female. 

 The dark area of the tegmina of the male ranges from weak cinna- 

 mon-brown proximad, paling distad to very weak snuff brown, 

 to solidly blackish fuscous, as a broad, uniform continuation of 

 the postocular bars. In the female, as in the male, the tegminal 

 coloration is controlled by the depth of coloration of the postocular 

 bars, and in this sex they are invariably of the same tone, regularly 

 weakening distad, much the darkest along the proximal section 

 of the costal margin and along the humeral trunk, thus contrasting 

 the enclosed pale subcostal bar. Rarely, in the female sex, a 

 maculate tendency, such as found in maculipennis, occurs" in 

 variable intensity and extent. An infuscation of the face occurs 

 more or less distinctly in numerous specimens, but it is strongly 

 contrasted and very striking in eastern males alone. The caudal 

 femora range in coloration from brazil red, through scarlet and 

 carnelian red to hazel. 



The geographic correlation of coloration seems best summarized 

 by stating that intensive coloration in its maximum development, 

 i. e. very dark postocular bars, medio-longitudinal bar, very dark 

 tegmina and infuscate face, is developed only in the southeastern 

 states, with Kansas specimens closely approaching it, while Texan 

 material chiefly represents the recessive type and stages approach 

 that extreme, with a factor for maculation, such as found in mac- 

 culipennis, becoming evident in that region. The Texan series 

 is sufficiently extensive to show that local conditions are strong 

 influencing coloration factors, while at the same time individual 

 variation, chiefly in the female sex, is considerable in series as ex- 

 tensive as those from Flatonia, Rosenberg and Navasota. 



The hays russet tone of general coloration is found in a single 

 female from Lane, South Carolina. 



Distribution. — The range of this species extends from eastern 

 North Carolina (Havelock) and the higher country of northern 

 Alabama (Chehawhaw Mountain), to eastern Georgia (Billy's 

 Island) and northern Florida (Pablo Beach), westward along the 

 Gulf Coast probably continuously to Texas; westward in which 



"Wichita Falls, Tex. (1); St. Jo, Tex. (1); Shovel Mountain, Tex. (7); Fla- 

 tonia, Tex. (2).
