168 NORTH AMERICAN MELANOPLI (ORTHOPTERA) 



tensive but obscured. All are darker and less red-brown than is usual in 

 this group, in this respect showing nearest superficial similarity to the series 

 of diver gens Morse which I secured on Jones Peak. Different responses 

 in these features to immediate environment is, however, to be expected. 

 Other paler and dark markings just as in the other species of the group. 



Measurements. — Two male and one female paratypes bearing the same 

 data show, with the type and allotype, the following extremes in measure- 

 ments: length of body 3 16.2 and 172, $ 22.3 and 23.3; length of pro- 

 notum 3 4.2 and 4.4, $ 5.2 and 5.3; caudal width of pronotal disk 3 2.8 

 and 3., $ 3.8 and 3.8; length of tegmen £ 2.8 and 2.9, 9. 3.8 and 4.; 

 length of caudal femur 3 9.7 and 10.3, $ 11.5 and 12.2 mm. 



This may prove to be a species confined to the valleys and 

 lower slopes in the mountains.

I collected a series of this interesting species, distinctive in the 

 angulate production of the ventral margin of the male cerci at 

 4000 feet on Jones Knob in the Balsam Mountains in a glade in 

 the deciduous forest (just below the thickly conifer-clad summit) , 

 which was reported by Rehn and Hebard in 1910. 



Specimens now before me. 



North Carolina: Crestmont in Haywood County, from 1800 to 3000 

 feet, VII, 28 and 29, 1922, (T. H. Hubbell), 23, 2$. Indian Pass in the 

 Great Smoky Mountains, IX, 4, 1933, (R. Dury), 43, 2$, [Ohio State 

 Mus. and Hebard Cln.]. Hendersonville, VI, 21, 1924, (H. Fox), 1$. 

 Jones Knob in Balsam Mountains, 2 3, 2$, paratypes; 33, 3$, [Hebard 

 Cln. and A.N.S.P.]. 



Georgia: Rabun Bald, 4600 to 4717 feet (summit), IX, 5, 1917, (Rehn 

 and Hebard; very scarce in huckleberry bushes and grasses under low oaks 

 and chestnut trees), 33, 4$ , [Hebard Cln. and A.N.S.P.L Chestnut Ridge 

 on Rabun Bald, IX, 5, 1917, 4000 feet, (Rehn and Hebard; few in similar 

 environment but richer undergrowth under higher trees), 33, 5$, [Hebard 

 Cln. and A.N.S.P.]. 



This species is, I believe, confined to the most boreal spots in 

 the southern Appalachian Mountains. Its distribution is, there- 

 fore, highly discontinuous.
