Scudder has properly placed modestum and taeniatum. in the 

 S3'nonymy under the present species. ^"^ 



Typical saltans is normally small to very small, and both slender 

 and delicate in structure. A brown phase of coloration is fre- 

 quently met with, particularly in the southeastern states, but 

 a green color form is also not unusual elsewhere, and in this 

 phase the insect verj^ closely resembles a small example of C. 

 stricius. 



Pronotum with cephalic margin convex and ventro-cephalic 

 angle weakly indicated to the broadly rounded ventro-caudal 

 angle which is almost 90°, caudal margin weakly convex to the 

 verj' broad and distinct humeral sinus, convex callosity very 

 broad. 



An extremely brachypterous type is normal, and it is con- 

 sequently rather surprising to find twelve of the two hundred and 

 six specimens recorded strongly macropterous, all of these being 

 from the western portions of the insect's distribution. 



The caudal femora have the ventral margins unarmed, the 

 genicular areas not darkened and the genicular lobes uni- 

 spinose. 



The male cerci are of a wholly different type from that of any 

 other North American species, being very slender with a very 

 long slender tooth situated interno-mesad and slightly beyond the 

 middle of the shaft; the distal portion of the cercus tapers evenly 

 to the narrowly rounded apex and is very weakly indented above. 



The ovipositor is normally weakly curved and in length meas- 

 ures as follows: Atsion, New Jersey, 10.5-10.7; Fern Hill, 

 Pennsylvania, 12.6-12.9; Asheville, North Carohna, 10.9 13; 

 Thomasville, Georgia, 13.8-15.8; West Point, Nebraska, 9.7- 

 13.8; Sidney, Nebraska, 10.8-13.2; southwestern Nebraska, 

 15; Dodge City, Kansas, 15.2; Colorado Springs. Colorado,. 

 14.1-15.3; Dallas, Texas, 15.9. 



The present insect is one of the latest species to appc^ar in the 

 southeastern United States, the great majority wei-e found on 



*8Can. Ent., xxx, p. 184, (1898).
