334 FAMILY VI. ACRIDID.E. THE LOCUSTS. 



This opinion is the more enhanced by the fact that pratensis has 

 been taken in the same region by Morse, who states (1907, 12) that 

 "the Florida examples of //. pratensis present a distinctly differ- 

 ent type of coloration one seen in some California series of the 

 species. They are also of small size like them but differ in having 

 much longer tegmina and wings. H. pratensis as it stands to-day 

 should be regarded as a variable and complex species represented 

 in different parts of the country by several more or less distinct 

 varieties. 1 " It is possible that a large series of all three forms 

 will show that yemmicula is the real connecting link between 

 brevipennis and pratensis, and that all three are only variable ex- 

 tremes of one widely distributed species which w r ill bear the name 

 brevipennis. 



Hebard states that "the species is peculiar to very sandy areas; 

 at Big Bayou it was found occasionally in a bushy low sand-loving 

 plant, at Pensacola very scarce among the undergrowth of scant 

 grasses and sand-loving plants in forest of long- leaf and small 

 sand-pines. At Carrabelle very few were taken through the low 

 bushes of the sand dune areas, w r hich are covered heavily with 

 arenicolous shrubs and bushes and some scrubby pine and oaks. 

 Only with particular effort was it possible to secure the series. 

 Heavy beating was found to be the most productive method." 



146. HESPEROTETTIX OSCEOLA Hebard, 1918, 161. 



Male Larger and slightly more robust than in gemmicula. Dark bar 

 of prozonal lateral lobe narrow, solid in coloration, its lower border white, 

 as broad, or twice as broad as the bar itself. Hind femora green with- 

 out dorsal dark bars or pink suffusion, the pinkish annulus near knee 

 broad and distinct. Tegmina usually appreciably shorter than pronotum, 

 rarely very slightly longer, feebly overlapping; their form broad ovate, 

 the dorsal field distinctly defined from lateral one. Tegmina colored as 

 in gemmicula. Genitalia as there, the cerci in the narrow distal portion 

 with margins feeble convex. Furcula visible as small subquadrate pro- 

 jections. Basal half of supra-anal plate higher than the apical portion; 

 pallium not conical and elevated as in gemmicula. Female Size much 

 larger, form more robust. Medio-dorsal stripe of pronotum decidedly 

 broader, pale with very dark margins, continued on abdomen to near its 

 apex. Length of body, , 16.1 18.5, 9, 21.4 24.5; of pronotum, $,

Ocala and DeLeon Springs, Fla., Sept. 8 20; two males, four 

 females taken by R. & H. "The species was exceedingly scarce, 

 very long search on four days having been made to secure the six 

 examples. Like ycinniicula it was found peculiar to very sandy 

 areas. At DeLeon Springs one individual was beaten from a
