(short form) feebly bisinuate (long form); tegmina very minute, 



$ , larger but almost concealed, 5 ; pronotum with front dorsal

 Locust.

 wider than one of the eyes, male, one-half wider, female, more or less con- 

 cave each side of median carina, its front margin feebly rounded. Frontal 

 costa, viewed in profile, slightly produced in front of eyes, narrowed and 

 compressed at point of union with median carina of vertex. Eyes glo- 

 bose, prominent. Pronotum as described in key, its apex in short form 

 acute, not quite reaching tips of hind femora, in long form surpassing 

 them by 3 mm.; median carina distinct throughout; tegminal sinus shal- 

 low, the lower one deep, acute, the lobe between them rather sharply 

 rounded. Wings in short form not reaching tip of pronotum, in long form 

 surpassing them 1.5 mm. Length of body, $, 8 8.5, 9, 9 10; of prono- 

 tum, $, 7 8, $, 7.5 8.5; of hind femora, $ and $, 5 5.G mm. Of long

Crawford County, Ind., July 25, one male, long form ; Dunedin, 

 Lakeland, LaBelle and Moore Haven, Fla., Jan. 9. March 30, 

 short form (W. 8. B.) ; Thomasville, Ga., June 19 Sept. 23 (He- 

 bard) ; Bloomington, Ind. (U. 8. N. M. Coll.). From Florida it has 

 also been recorded from eleven other localities between Pablo 

 Beach, Gainesville, Miami and Ft. Myers, and probably occurs 

 throughout the State. Ranges from Stateu Island, N. Y., Maryland 

 and southern Indiana, south and west to Florida, Columbia, Te.v- 

 as, Oklahoma and Iowa. At Dunedin it was found only along the 

 sandy margins of recently drained ponds in company with y. c. 

 floridanus Hck. and Apotettix rugosus Scudd. In other places it 

 is recorded as occurring in open pine woods and palmetto scrub. 



Morse (1907, 25) says femoratus is "one of the most plentiful 

 of Tettiginae in the southeastern quarter of the country, often 

 occurring in great abundance in specially favorable localities, 

 generally preferring sandy soils which are frequently or perpetu-

 ed between the long and short forms, but long-winged examples 

 are usually much fewer, ranging from 5 to 20 per cent. At Dune-
