Hastings, Orlando and Dunedin, Fla., July 5 Jan. 1 

 ( W. S. B. ) . About Dunedin this small Tettigoniid is frequent in 

 late autumn and early winter but apparently succumbs to the 

 first frost. It occurs mainly amidst the wire-grass and low 

 huckleberry bushes of open pine woods, but also among the taller 

 grasses growing in old fallow fields and on the sites of wet- 

 weather ponds. It was described from Hastings, Fla., and is re- 

 corded by other collectors from numerous localities throughout 

 the entire mainland and on the southern keys. As will be noted 

 by the measurements, the females vary much in size and in the 

 length of ovipositor. They have been heretofore described as be- 

 ing totally apterous, but they have rudimentary tegmina con- 

 cealed by the pronotum. In a specimen from Orlando these are 

 large enough to protrude slightly beyond the pronotum. The 

 males usually carry the cerci in a reflexed, almost perpendicular 

 position within the cavity of the long projecting scoop-shaped 

 subgenital plate. 



The known range of 0. apterum extends from Fayetteville, 

 N. Car., to Key West, Fla., its main distribution being in Georgia 

 and Florida. R. & H. (1916, 267) say that "Throughout the low 

 country of the Carolinas, Georgia and Florida this is one of the 

 most ubiquitous species in the undergrowth of the pine woods 

 and on the palmetto flats. At a number of localities it was par- 

 ticularly numerous about oak shoots in such situations. The 

 stridulation is a very faint and intermittent zip-zip-zee-zee-zee 

 zip-zee-zee, etc. The males when stridulating often climb high 

 up in the undergrowth, sometimes three or four feet from the 

 ground." 

 274a. ODONTOXIPHIDIUM APTEBUJI AFFINE var. nov. 



Size and form of 0. apterum. Differs as follows: Color paler; me- 

 dian dark stripe of occiput and prozona vague, the yellowish ones below it 

 faint or wanting; abdomen without dark markings in either sex. Fastig- 

 ium of vertex more strongly ascending, its apical half with sides rounded, 

 distinctly wider than middle. Pronotum less sellate; humeral sinus evi- 

 dent but faint. Cerci of male distinctly stouter, subdepressed, their apical 

 portion subtriangular, the tooth at apical third stouter and slightly curved
