cerci, which are subconstricted mesad, and in the rounded and 

 hardly produced apical margin of the subgenital plate of the same 

 sex. The females of the three species are very similar, but the 

 constantly longer tegmina and slightly less bicolored character of 

 the same in querneus enable one to distinguish it. 



Type: cf ; Thomasville, Thomas County, Georgia. November 30, 

 1903. (Morgan Hebard.) [Hebard Collection, Type No. 116.] 



Description of Type. — Size large; form moderately robust. Head 

 as in nigrescens except for the frontal costa failing to reach the 

 clypeal suture ; antennae very long, slightly longer than the pronotum 

 and tegmina together. Pronotum as in nigrescens. Tegmina almost 

 or quite reaching the region of the furcula when the abdomen is in 

 the usual somewhat recurved position, appreciably longer than in 

 nigrescens, considerably exceeding the combined length of the head 

 and pronotum, subacuminate, the apices narrowly rounded; sutural 

 margins moderately arcuate. Prosternal spine similar to that of 

 nigrescens; interspace between the mesosternal lobes slightly broader 

 and less decidedly longitudinal than in nigrescens; interspace between 

 the metasternal lobes subattingent, but not contiguous as in nigres- 

 cens. Abdomen subcompressed proximad, with a fairly distinct and 

 moderately elevated medio-longitudinal carina; furcula merely 

 the briefest of points projecting from the disto-dorsal abdominal 

 segment, poorly indicated on the surface of the segment as broad, 

 rounded areas, between which the segment is emarginate ; supra-anal 

 plate as in nigrescens, but the proximal medio-longitudinal sulcus 

 and its marginal carinas are more decided and the median transverse 

 carina is more strongly indicated (fig. 3); cerci broad, sublamellate, 

 the greatest distal width hardly more than half the length, broad 

 at base, somewhat narrowing to the middle, the whole dorsal margin 

 arcuato-emarginate, the disto-dorsal angle rotundato-rectangulate, 

 distal margin arcuato-truncate and gently rounding into an obliquely 

 truncate disto-ventral section, which latter passes by a very slight 

 angle into the ventral margin, distal section with surface faintly 

 tumid and separated from distal margin by an arcuate impression 

 (fig. 1); subgenital plate distinctly broader than long, the apical 

 margin semi-elliptical in shape when seen from the dorsum, when 

 seen from the side moderately emarginate with a faintly produced 

 extremity (fig. 2) . Cephalic and median limbs slightly more elongate 

 than in nigrescens. Caudal femora similar to those of nigrescens, 

 but dorsal outline more concave distad; caudal tibiae with external 

 spines ten to eleven in number.
