mere proportional reduction. The average difference is 1.4 mm., 

 the Sulphur Springs specimens averaging 12.9 (12.5-13.5), the Pisgah 

 series 11.5 (11.2-11.8). The Mt. Pisgah specimens are, as a rule, 

 darker and somewhat less contrasted than the Sulphur Springs series. 

 The length of the furcula is, as stated by Morse, quite variable. 



The species was never found in the least plentiful about Sulphur 

 Springs. Its habitat proved to be constantly sylvan. 

 Melanoplus decorus Scudder. 



This little-known species is represented by six males and one female 

 from Winter Park, taken August 26, 1908, and four males from New- 

 Berne, August 24, 1908. In size there is quite a little variation as the 

 caudal femora of the males range between 9.5 and 11.2 millimetres 

 in length. The general coloration varies appreciably from a general 

 gamboge-yellow to fawn color, while the coloration of the face varies 

 from uniform with the body to walnut-brown. The blackish coloration 

 of the tubercle of the subgenital plate of the male is quite striking. 



The previously unique types were taken at Dingo Bluff, N. C. 



At New Berne the species occurred in a piece of moist meadow land. 

 and at Winter Park it frequented high grass in wet spots in long-leaf 

 pine woods. The species was scarce at New Berne, but more numerous 

 at Winter Park. 



Melanoplus ampleotens Scudder. 



At Balsam this species was found at elevations of from 3,500 to 4,000 

 feet on October 7, 1905. while the same day it was secured at 5,000 

 feet elevation on Jones's Knob. On October 1. 1904, it was taken at 

 4,500 feet and 5,700 feet (summit) on Mt. Pisgah. Balsam is repre- 

 sented by two males and eight females, Jones's Knob by two males and 

 three females and Mt. Pisgah by two males and six females. 



Morse has already called attention to the variability of this species, 

 and our material substantiates his remarks. The variation in the 

 length of the tegmina is very considerable in some specimens, the 

 extremes of the males measuring 4.2 and 7 mm., of the females 5.5 

 and 8, all measured being from Mt. Pisgah except the male with shortest 

 tegmina, which is from Balsam. All the specimens of this species 

 were found in distinctly sylvan surroundings where grass was present 

 in some quantities, excepting in the case of those taken on the summit 

 bald of Mt. Pisgah. 



Melanoplus divergens Morse. 



Three males and three females of this species taken at Balsam, 

 4,000 feet elevation, on October 7, 1905, are practically topotypes.
