Melanoplus celatus sp. nov. 



Closelv related to M. idandtcus, agreeing with it in size, coloration, markings and form 

 with the following exceptions. 



Cerci of male similar to those of islandicus, stout at base, tapering equally, or moie 

 rapidly in basal portion, to a slender, flattened tip, once and a half or twice as long as width 

 of base, symmetrical, the tip not bent upward nor grooved externally as usual in islandicus. 

 Subgenital plate averaging shorter on the dorsal margin than in islandicus. Prosternal 

 spine conic or cylindro-conic, the apex blunt, well-rounded, — in islandicus subpyratnidaU 

 acutely pointed, the sides flattened. 



Five males, three females, Wytheville, Wythe Co., \'a.. Sept. 4 and 5, 3000 to 4000 feet. 



Melanoplus sylvestris sp. nov. 



This species also is a near relative of islandicus Blatchl., differing chiefly in the form of 

 the male cerci, which, while of the same general structure, are narrower at base and have 

 the distal half bent slightly upward and drawn out into a slender, compreSSed, substyliforni 

 tip, the whole appendage being once-and-three-quarters or twice as long as the width of base. 

 The prosternal spine is very variable, ranging from siibcylindrical with bluntly rounded X.'ty> 

 to a more usual conical form with rounded apex. 



Seven males, seven females. Blowing Rock, Watauga Co., N. C., July 19. Two females, 

 Linville, Mitchell Co., N. C, July 18. Six males, six females, Loverings', Burke Co., 

 (between Morganton and Pineola), July 13. Two females, Pineola, Mitchell Co., N. C, July 

 13 ; one male, ( .?) same place, Aug. 28. All at elevations of 3500 to 4000 ft. 



The three species, — islandicus, celatus, and sylvestris — are evidently nearly related 

 descendants of the same parent form, modified by isolation. Intergrades may yet be dis- 

 covered. The male from Pineola is included with some doubt owing to differences in struc- 

 ture and season. 



Melanoplus carnegiei sp. nov. 



A .short-winged species related to and resembling scudderi but witli the cerci siiortiT. 

 about as long as their basal breadth, equalling three-fifths of the supra-anal plate, triangular, 

 acutely pointed, the sides straight or a little sinuous by reason of convexity of base ; tlie 

 ventral margin is usually the longer but sometimes the sides and base are subequal ; thick 

 at base, tapering evenly to the not at all incurved apex. Subgenital plate scoop-shaped, tlie 

 end pointed, the apex rounded or slightly truncate. Furcula minute, barely discerniiilc, 

 scarcely half as long as last segment. Supra-anal plate triangular, longer than wide, pointed, 

 the sides convex. 



Pronotum resembling that of scudderi but scarcely as wide posteriorly ; prosternal spine 

 very variable, sometimes cylindrical and bluntly pointed, more usually flattened antero- 

 posteriorly, apex broad and bluntly rounded or acute with straight sides. Tegmina shorter 

 than in scudderi, nearly as long as pronotum, bro^id lanceolate with rounded apex, attingeni 

 or slightly overlapping. 



Color and markings as in scudderi, the hind tibiae red.
