Transition zone of Central and Appalachian regions. This is 

 a characteristic and dominant species among the mountains of 

 western North Carolina, inhabiting thickets of shrubbery, and 

 herbage in and near deciduous woodlands at high elevations and 

 sometimes extending its habitat into the adjoining fields. The 

 cerci and furcula of the male are very variable in size and propor- 

 tions, but there seems no doubt that the two names have been 

 applied to the same species, which has a wide range in the Central 

 States and is exceedingly plentiful in places as well as widely dis- 

 tributed in the southern Appalachians. Adults of this species 

 begin to appear in small numbers about the middle of July, but the 

 great majority do not reach maturity until August and young are 

 still plentiful in September at high elevations.

" Related to attenuatus. Tegmina lanceolate with rounded 

 tip, in attenuatus elliptical, and almost truncate at apex. Furcula 

 processes well-developed, broad at base, tapering (chiefly on inner 

 side) to digitate tips, one-third as long as supra-anal plate, in 

 attenuatus one-fourth or less. Supra-anal plate resembling that of
