174. MELANOPLUS STEGOCERCUS Rehn & Hebard, 1916, 223. 



Form of M. rotundipennis but slightly larger and more compact. Color 

 much as there, the black postocular stripe extending the full length of pro- 

 notal lobes and along the sides to middle of abdomen in both sexes. Dor- 

 sal surface of abdomen and outer face of hind femora often largely fus- 

 cous; upper and inner faces of hind femora with three blackish cross-bars. 

 Disk of pronotum rounded into the lateral lobes, the lateral carinse very 

 faint, feebly divergent backward, male, more strongly so, female; hind 

 margin of metazona rounded, without trace of median notch. Tegmina al- 

 most as broad as long, tips subtruncate, more distinctly so in female. Su- 

 pra-anal plate elongate-triangular, the median basal ridges very broad, the 

 sulcus between them wide, shallow, ill defined, percurrent or nearly so 

 (Fig. 133, o.) Cerci as described in key, the apical sixth impressed. Sub- 

 genital plate rather narrow, subcompressed, about 2 mm. in length, its 

 apex narrowly rounded. Length of body, $, 15 17.5, 9, 19 22; of pro- 

 notum, $, 3.84, $, 4.85; of tegmina, $, 33.2, $, 3.84.2; of hind fe-

The above description was drawn from a series of specimens in 

 the Philadelphia collections taken by R. & H. near Groveland, 

 Ga., Sept. 21. The unique male type collected by Bradley July 

 28, Avas from the same locality. There is no record of its occur- 

 rence elsewhere, nor of its habits. 



175. MELANOPLUS SCAPULARIS Rehn & Hebard, 1916, 226. 



Color and measurements as in stegocercus. The male differs in the 

 form of cerci as described in key and shown in Fig. 132, the apical third 

 being widely expanded, broadly emarginate, the upper outer lobe the 

 longer with apex rounded. Subgenital plate a little shorter, less com- 

 pressed with apex wider, subtruncate. The females differ only in having 

 the tegmina a little more narrow with apex more evidently rounded 

 (Fig. 134, c.) 



Known only from Jesup, Sandfly and Isle of Hope, Ga., and 

 Woodville, Fla., Sept. 1 3. At Jesup it was found "in a re- 

 stricted area of a sandy tract covered with low bushy plants, 

 such as Myrica />iiiniJ<i Michx., (Jin-rcux minima Sarg., gall-berry 

 bushes and saw palmettoes, and at the other localities "in scant
