Hastings, Flu., Aug. 27 Sept. 5. Scudder's types were from 

 Jacksonville, and it lias been recorded by R. & H. and Morse from 

 Pablo Beach, Gainesville, Cedar Keys, Live Oak, DeFuniak 

 Springs, Lakeland and Pine Island, so that it probably occurs 

 throughout the State. The Pine Island specimens were nymphs 

 taken by Hebard, May 18 20 ; the other records of adults, Aug. 

 November. 



G-. inisillns is so far known only from Georgia and Florida, its 

 northern stations being Jesup and Brunswick, Ga. Morse (1904, 

 39) recorded it as "locally abundant at Waycross, Ga., in the open, 

 lower marshy portions of the pine barrens, inhabiting a matted 

 growth made up of pipe-wort, sedge and juncus stems." R. & H. 

 (191(1, 207) state that in southeastern Georgia and northeastern 

 Florida it is "frequently exceedingly plentiful locally in the heav- 

 ier undergrowth of the long-leaf pine forests, especially where the 

 ground is low." Hebard says that "they are masters of the art of 

 jumping. They can leap so quickly that the eye cannot follow 

 them and can jump in any direction with such rapidity that it is 

 impossible to see where they have gone. They jump from one tuft 

 of wire grass to the top of another tuft, and there cling tightly 

 to the highest straw, ready to make another leap." The species 

 is one of the smallest and without doubt the most slender-bodied 

 of all our eastern Acridians. 



139. GVMXOSCIRTETES MORSEi Hebard, 1918, 142. Morse's Wingless Locust. 



"Closely related to G. pusillits Scudder, agreeing in form, coloration 

 and color pattern. The genitalia of both sexes, however, offer striking and 

 constant characters for specific distinction. Male: Size larger than pusil- 

 lus. Head with interocular space about as wide as first antennal joint. 

 Prosternal spine rather elongate, beyond base rather slender, cylindrical, 

 scarcely tapering to the bluntly rounded apex. Supra-anal plate elongate, 

 shield-shaped, with surface longitudinally trisulcate, the lateral margins 

 moderately reflexed and with two small, elongate, longitudinal convexities 

 proximo-laterad of the small projecting apex. Cerci specialized, distinctive 

 (Fig. 117, e.) Subgenital plate as described in key. Female.- Larger than 

 male, larger than in pusillus. Interocular space broader than in male, pros- 

 ternal spine heavier and shorter. Ovipositor valves elongate; the dorsal 

 pair with disto-dorsal declivity brief to the blunted apical tooth; the ven- 

 tral pair with disto-lateral and apical tooth blunted, the portion beyond the 

 disto-lateral tooth very brief. Length of body, $, 14.2 16.2, $, 19.5 21.5;
