166 NORTH AMERICAN MELANOPLI (ORTHOPTERA) 



lobes) leaving much more of the eetoparameres exposed in caudal 

 aspect, while their complex exposed distal portions are larger. 

 No intergradation between these conditions is shown by any of 

 the material studied. 



The following material is before me. 



Virginia: Wytheville, 1$, paratype. 



North Carolina : Blowing Rock, 1 $ , 19, paratypes of sylvestris. Lov- 

 ering's in Burke County, 1 $ , 1 $ , paratypes of sylvestris. 



South Carolina: Caesar's Head in Greenville County, VI, 29, 1926 and 

 VIII, 23, 1933, (F. Sherman), 2$ (apices of cerci slightly broader than 

 typical), 1$, [Sherman and Hebard Cms.]. Pinnacle Mountain in Pickens 

 County, VI, 19, 1934, (F. Sherman), 1$ (apices of cerci unusually broad, 

 as broad as broadest developed in islandicus, from Sounding Knob, Vir- 

 ginia). Rocky Bottom in Pickens County, VI, 16 to X, 3, 1927 to 1932, 

 (F. Sherman), 5$ (apices of cerci varying from slightly to decidedly 

 broader than typical), 9$, [Sherman and Hebard Cms.]. Cashiers Valley 

 Road in Oconee County, X, 16, 1934, (0. L. Cartwright), IS (apices of 

 cerci considerably broader than typical). 



Georgia : 15 Pinnacle Peak in Rabun County, 1 $ . Rabun County, 1 9 , 

 [A.N.S.P.]. Clayton, 2000 feet, 1$ (apices of cerci considerably broader 

 than typical). 



Tennessee: Clinch Mountains in Grainger County, IX, 2, 1933, (R. 

 Dury), 1 # , 1 $ (typical, size very large for the species), [Ohio State Mus.]. 

 Allardt in Fentress County, 1200 feet, VIII, 16, 1922, (T. H. Hubbell), 

 1$ (apices of cerci slightly broader than typical). Grassy Cove in Cum- 

 berland County, 1800 and 2000 feet, VII, 11 and 13, 1922, (T. H. Hubbell), 

 2$, 2$. 



The known distribution of this insect is defined by the above 

 localities. More material from all parts of its range is badly 

 needed. The single series before me, from Rocky Bottom, South 

 Carolina, shows so much individual variation in the form of the 

 male cerci that I do not believe a geographic race of the more 

 southern area can be recognized, though an average greater, and 

 sometimes strikingly greater, width of the cereal apices is there 

 present.

Generally similar to the other species of this group, the present 

 species is nearest mancus in the form of the male cerci which, 



15 This material and a female from Black Mountain, North Carolina, 

 was recorded as sylvestris by Rehn and Hebard in 1916, at which time that 

 the possibility that it represented a race of islandicus was suggested.
