The only previous record of this species is from Live Oak, Suwanee 



County, Fla. 



Hesperotettiz floridensis Morse. 



Two males and a female of this peculiar species were taken at Pablo 

 Beach, August 12 and 13, and a second female at San Pablo, August 13. 

 The Pablo Beach specimens were taken among grass in marshy spots 

 in the palmetto scrub, and in tall grass growing in a wet drain along 

 the railroad track. The San Pablo specimen was taken in undergrowth 

 in pine woods. 



The previous records of this species are from Hastings, St. John 

 County, Fla., and Waycross, Ware County, Ga. 



Melanoplus propinquus Scudder. 



This austral representative of M. femur-ruhrum is represented by a 

 series of thirty-three specimens taken at four localities, at all of which 

 the species was abundant in a variety of situations. The localities 

 and dates are: Jacksonville, August 11, two males, one female; Pablo 

 Beach, August 11-13, fourteen males, three females; Gainesville, 

 August 16, four males, two females; Cedar Keys, August 15, three 

 males, four females. At Jacksonville it was taken on a city lot, while 

 the Pablo Beach series was collected in palmetto scrub, open grassy 

 stretches and in tall marsh grass. 



Size is a very variable character in this species and does not appear 

 to be correlated with exact environment, one of the smallest and one 

 of the largest males both being from tall marsh grass at Pablo Beach. 

 Maximum and minimum measurements from Pablo Beach males are 

 as follows : 



Length of body, 22.2 mm. 17.6 mm. 



Length of pronotum, 5.1 " 4 " 



Length of tegmen, 20.2 " 15.8" 



Length of caudal femur, 13 " 10.7 " 



Melanoplus inops Scudder. 



A series of sixty-nine specimens represents this species, which was 

 taken at all the points where any amount of collecting was done. The 

 localities represented are: Pablo Beach, August 11-13, nine males, 

 nine females; San Pablo, August 12, four males, three females; Gaines- 

 ville, August 16 and 17, twenty males, fourteen females; Cedar Keys, 

 August 15, two males, seven females, one nymph. At Pablo Beach the 

 species was numerous in the open palmetto barrens; at San Pablo, 

 Gainesville and Cedar Keys it frequented the undergrowth in pine 

 woods, sometimes, particularly at Cedar Keys, among saw palmetto. 



The cerci of the males exhibit an appreciable amount of variation, and
