Spharagemon (ff<papayiop.at) nov. gen. 



Body compressed. Head rather tumid above, the vertex as decli- 

 vant as the back of the head, broad, tapering rapidly, scarcely 

 sulcate, the eyes separated by more than double the width of the 

 basal antennal joint. Front vertical, scarcely convex on a side view, 

 the costa moderately broad, nearly equal, slightly contracted above 

 the antennae, more or less sulcate throughout, excepting at the ex- 

 treme upper end, its lateral ridges continuous with those of the 

 vertex, the lateral foveolae rather small, scarcely sulcate but more or 

 less distinct, triangular, close to the eyes. Eyes rather small, trans- 

 versely short obovate. Antennae about as long as the hind femora 

 in both sexes, a little flattened, especially near the base, some of the 

 apical joints very short. Disc of pronotum moderately flat, the 

 median carina cristate or subcristate, strongly compressed almost 

 from its very base, divided obscurely but to the very base by the 

 principal transverse furrow into two parts, the front portion a little 

 the longer, the edge of the ridge straight or nearly straight on the 

 front lobe, and arched more abruptly in front than behind on the 

 hind lobe ; lateral carinae nearly obsolete, excepting behind ; the front 

 lobe equal, its front margin very slightly angulated ; hind lobe ex- 

 panding posteriorly, its hind margin generally more acute than a 

 right angle. Tegmina extending beyond the tip of the abdomen, 

 nearly equal, slightly sinuous, obliquely excised apically, traversed 

 by three bands of more or less distinctly agglomerated dark flecks. 

 Wings subtriangular, yellowish at the base, crossed beyond the mid- 

 dle by a continuous broad dark belt. Hind femora rather stout and 

 short, scarcely, if at all, surpassing the tip of the abdomen. Type: 

 Gryllus cequalis Say.
