1904] MORSE: — NEW ACRIDIIDAE 9 



the base the dorsal margin is deeply concave, the ventral margin strongly angulate, beyond 

 the angle straight or a little concave, forming a sub-bifurcate organ as long as the supra-anal 

 plate. The whole appendage is thick, strongly convex externally, especially on the tip, which 

 is curved gently inward. 



General color dark reddish brown above, yellowish beneath, the hind tibiae red. Post- 

 ocular fuscous stripes on head and prozone and pronounced fuscous markings on sides of 

 abdomen and hind femora. The female is sometimes yellowish brown above. 



Length of body: J, 9-10; $, 11-20; hind femora: $, 8.5-9.5; ?5 9-5-ii; antenna:

Eight males, eleven females, Balsam, Jackson Co., N. C, July 24, about 5000 ft. Seven 

 TTiales, seven females, Aug. 19, 5000-6000 ft. 



Melanoplus deceptus sp. nov. 



Melanoplus viridtpes in part. Scudder, Rev. Melanopli, p. 255. 



Agreeing with viridtpes in size, color, and markings but differing in the form of the 

 cerci : in viridipes these organs taper somewhat regularly to the apex ; in this species more 

 or less of their distal third is distinctly broadened dorsally and obliquely excised at the end, 

 the apex being acute and ventral ; the ventral margin may be convex, straight, or slightly 

 sinuous, the dorsal margin is concave in the mesial portion, sometimes strongly so. The 

 whole organ varies much in breadth in different specimens. 



Owing to its strong resemblance to viridipes this species has been confused with it by 

 various authors and a specimen was included with the types of that species. The original 

 descriptions and drawings, however, accurately delimit viridipes from this and the suc- 

 ceeding species. 



Three males, eight females. Balsam, Jackson Co., N. C, Aug. 19, 5700-6100 ft. i male, 

 Jasper, Pickens Co., Ga., July 26, 2600 ft. Three males, Vigo Co., Ind., June 8, received 

 from Blatchley. One male, Indiana, Scudder collection in M. C. Z., type of viridipes. 



Melanoplus similis sp. nov. 



V^ery similar to viridipes and deceptus. The tip of tiie abdomen is less clavate and 

 upturned ; the basal half of the cerci tapers rapidly on the dorsal side to less than half the 

 width of the base, sides of distal half parallel, apex transversely excised, the angles rounded, 

 the dorsal one slightly more prominent ; the ventral margin is nearly straight, though 

 slightly concave and sinuous, the dorsal margin strongly concave in the middle, convex 

 at base. 



In color and markings this species strongly resembles viridipes and deceptus but 

 possesses distinctive characters in the markings of the abdomen (as well as in the form of 

 the cerci). In this species the subgenital plate is shining black, the preceding sternite 

 greenish white with a very broad triangular fuscous spot extending across its posterior 

 margin below the upturned subgenital plate from which it is separated by a lenticular pale 

 space along the suture. In deceptus and viridipes the anterior margins of several of the 

 abdominal sterna are conspicuously infuscated as well as both margins of the sternite pre- 

 ceding the subgenital plate. 



Three males, Murphy, Cherokee Co., N. C, July 25.
