596 FAMILY VII. TETTIGONIID^E. THE KATYDIDS. 



distinct, the very evidently upcurved ovipositor and the broader, 

 more U-shaped notch of subgenital plate. 



The known range of this mountain-loving species extends from 

 near Dnrbin, W. Va., to Clayton, Ga., at elevations of 2,1)110 to 

 G,00() feet. At Jones' Knob, N. Car., it was taken by K. & H. on 

 July 1!) and Oct. 7 in the undergrowth of the deciduous forest 

 immediately below the spruce belt.

North Madison, Conn., Aug. 25, one pair from the crests of 

 high rocky ledges along the Hammonasset River ( 11'. #. B. ) . Yap- 

 hank, Long Island and Lakehurst, N. Jer., Aug. 27, Sept. < 

 (Davis). A common form of the northeastern states and, ac- 

 cording to R. & H., the one to which Scudder (1802) and most 

 subsequent authors applied the name dorsal is Burm. Its known 

 range extends from central New England west to the Appalachian 

 Mountains and southwest to northern Florida, central Alabama 

 and Natchez, Miss. Saussure's types were from Tennessee. The 

 Connecticut record above given is the first definite one for that 

 State. The only known Florida station is River Junction where 

 on August 31 R. & H. took five males and four females from 

 "among tree shoots in heavy forest of beech, hickory, oak and 

 magnolia on limestone hills.'' They state (1910a, 79) that (imcri-

 growth in pine and deciduous forests, occasionally being more 

 numerous along the edges of the timber than in the depths of the 

 woods. Its presence will often be signalized by the patter on the 

 leaves as it jumps away from the disturbing footsteps. The in- 

 sects are so thoroughly protected by their coloration that it is 

 often difficult to see them, even when moving, much less when
