During November and December I have found this splendid species 

 in colonies among the pine woods. It preferred the vicinity of the 

 scrub oaks, and it was among these that I found a group of over a dozen 

 specimens of this species within the space of a few square yards. The 

 males seemed peculiarly unwary, and occasionally one would be almost 

 trodden before it would jump. Earlier in the season, during the warm 

 fall weather, they probably exhibited much greater activity, for I 

 noticed them to feel cold severely and the slightest cooler weather 

 would greatly thin their numbers. All the specimens I took were 

 probably at their prime several weeks earlier, and from this I conclude 

 that the best time to take this species is toward the latter part of 

 October and during early November. The females were more unwieldy 

 than the males but were very powerful. Both sexes, owing to the 

 shortness of their wings, were wholly unable to fly. (M. H.) 



Melanoplus keeleri (Thomas). 



This species is represented by a series of twenty males and twenty- 

 nine females taken at Thomasville in September, October, November 

 and December. The intensity of the coloration is quite variable. 



This species is found in the same locality and at the same time as 

 the preceding species, but in greater numbers. The males are much 

 smaller than the females, and are therefore less powerful, but they are 

 able to fly well and are occasionally quite shy. The females are usually 

 unable to fly at the time I was collecting as it was late in the season, 

 and all were more or less worn. (M. H.) 



Melanoplus clypeatus (Scudder). 



Four female specimens of this species from Thomasville, taken 

 August 3 and December 17, 1903, have been examined. They have 

 longer tegmina (22-22.5 mm.) than the female measured by Scudder. 



Melanoplus propinquus Scudder. 



This is the most abundant species of the genus at Thomasville, and 

 in consequence it is represented by a very large series — three hundred 

 and forty-eight in number. The months represented by the material 

 are January, INIay, June, July, August, Septeml^er. October and De- 

 cember. 



This species has almost the exact habits of its close northern ally, 

 M. femur-rubrum. It is found in great numbers in all open country 

 during the summer and fall and is quite plentiful even in the spring.

Melanoplus atlanis (Riley). 



This destructive species is represented by five male individuals 

 from Thomasville^ taken in April, July, October and December.
