testaceous stripe, the lateral lobes flavo-testaceous, more or less suffused 

 with fuscous, sometimes much iufuscated, rarely blotched with fuscous; 

 prozona slightly and roundly produced anteriorly, about as long as the 

 metazona, which is distinctly tumid dorsally in the female, and sometimes 

 in the male, expanding also so as to be about as wide as ((^) or consid- 

 erably wider than ( 9 ) the breadth at the eyes, posteriorly obtusangulate, 

 the angle broadly rounded. Prosternal spine moderate, erect, bluntly 

 acuminate. Tegmina extending somewhat beyond the abdomen, moder- 

 ately broad, testaceous or flavo-testaceous, the median area generally

 quadrate maculatious transversely arranged in the distal half ; wings faint 

 flavous with luteous veins. Fore and middle femora considerably tumid 

 in the male; hind femora flavous, flavo-testaceous or testaceous, generally 

 conspicuously trifasciate with fuscous, the fasciations more or less broken 

 and occasionally considerably reduced; hind tibite purplish or ferrugi- 

 nous, the spines luteous with black tips. Male cerci less than half as

 cally deeply and obliquely emarginate, the lower lobe the longer, more 

 extended and more broadly rounded; subgenital plate short, haustrate 

 rather than scaphiform, the apex deeply cleft in U -shape, the cleft more
