356 NORTH AMERICAN MELANOPLI (ORTHOPTERA) 



of the dorsal margin, shaft mesad thick and over half proximal 

 width, distal half moderately enlarged, the dorsal margin there 

 broadly convex to the sub-rectangulate and rather blunt disto- 

 ventral angle, ventral margin of cercus broadly concave. Com- 

 pared with that of cherokee the cercus is seen to be shorter and 

 broader with apical enlarged portion proportionately more ex- 

 tensive and disto-dorsad with its margin more oblique-declivent 

 to the disto-ventral apex. Subgenital plate small, with a stout 

 blunt apical tubercle. 



Allotype. — 9 ; same data as type. [Acad. Nat. Sci. Phila.]. 



Indistinguishable from females of typical acrophilus (except 

 that the tegmina in the series average shorter). The shorter 

 tegmina make females almost impossible to distinguish from this 

 sex of viridipes eury cercus. 



The extremes in the present series measure as follows. Length 

 of body c? 17. and 17.2, 9 19.5 and 22.3; length of pronotum 

 cf 4.7 and 4.4, 9 4.7 and 4.8; caudal width of pronotal disk 

 d 1 2.7 and 2.7, 9 3.4 and 3.3; length of tegmen & 4.7 and 4.8, 

 9 4.6 and 5.2; length of caudal femur cf 8.7 and 8.9, 9 9.7 and 

 10.8 mm. 



In addition to the type and allotype, two male and three female 

 paratypes and a male in the instar preceding maturity, bear the 

 same data except that they were taken from the 17th to the 26th 

 of July. 



Melanoplus deceptus Morse (PI. XXII, fig. 14; pi. XXIII, fig. 6) 



1904. Melanoplus deceptus Morse (in part), Psyche, xi, p. 9. [d\ 9; 



Jones' Peak, Balsam Mountains, North Carolina.] 

 1910. Melanoplus deceptus Rehn and Hebard, Proc. Acad. Nat. Sci. Phila., 



1910, p. 633. [cf, Tennessee.] 



Morse originally included in his original series of deceptus 

 specimens from Vigo County, Indiana and Jasper, Georgia, which 

 represent a distinct species, here described as hubbelli. In addi- 

 tion, the figure of the cercus which Morse published later in 1904 

 is very badly drawn and foreshortened to such a degree that 

 recognition of typical deceptus has been almost impossible. This 

 situation led to the assignment to deceptus of material of cherokee 

 here described from Black Mountain, North Carolina, and of 

 hubbelli here described from Clayton, Georgia, by Rehn and 

 Hebard in 1916. 



The size, form and coloration of deceptus agree fully with 

 cherokee as here described.
