358 NORTH AMERICAN MELANOPLI (ORTHOPTERA) 



Melanoplus cherokee new species (PI. XXII, fig. 15; pi. XXIII, fig. 7) 



This species, like the races of acrophilus here described, could 

 easily be mistaken for a race of deceptus were the penis not 

 examined, which in the present case is very widely different from 

 that of any of the other members of the Viridipes Group. 



In appearance and structure, even of the male genitalia, close 

 resemblance is shown to acrophilus and the student is warned 

 that mistakes in identification are certain to occur if the pallium 

 is not removed from above the penis in males so that the latter 

 can be examined. We have not been able to find anything by 

 which females of these species can be distinguished. 



Like acrophilus and deceptus the insect is unquestionably 

 sylvan, local and restricted in distribution to the southern Ap- 

 palachian Mountains. 



Type. — Crestmont; Great Smoky Mountains, North Carolina. 

 Elevation 3200 feet. July 21, 1922. (T. H. Hubbell). [Univ. 

 of Michigan]. 



Closely similar to acrophilus here described, agreeing in all 

 features here given except the penis. This in the present insect 

 has the lobes greatly narrowed, erect, curving evenly outward 

 and then inward so that they almost meet at their extremities, 

 the more caudal pair chitinized and with their caudal surfaces 

 transversely convex so that they conceal and act as outer sheaths 

 for the more cephalic pair. 



The following much less significant differences from the type 

 of acrophilus are shown by the present type. Cercus about two 

 and three-quarters times proximal width, tapering in proximal 

 third, distal three-fifths weakly enlarged. Apical enlarged 

 portion of cercus much longer than in hubbelli. Subgenital plate 

 with a stout blunt apical tubercle (which is less blunt in two 

 paratypes).
