Head varying from pallid testaceous to brownish testaceous, the 

 genae sometimes clouded with fuscous; a broad blackish stripe, usually 

 broadening posteriorly, extends from the front of the fastigium across 

 the summit, nearly occupying the whole of the fastigium except the 

 sides of the expanded portion and sometimes invading this; a broader 

 band extends longitudinally behind the eyes; antennae pale salmon 

 red, more or less deeply infuscated apically; fastigium not sulcate; 

 frontal costa nearly or quite as broad as the narrowest space between 

 the eyes, shallowly sulcate below the ocellus. Pronotum varying from 

 testaceous to dark brownish yellow, the metazona generally feebly infus- 

 cated in parts, especially on the disk, the prozona and generally the 

 front half of the metazona with a broad, obscurely bordered, blackish 

 fuliginous, mesial stripe, sometimes including a yellowish thread; upper 

 half of the lateral lobes of the prozona similarly colored, forming a 

 broad bar, which sometimes extends as a cloud upon the metazona; 

 posterior margin obtusely angulate, the angle rounded; median carina 

 on the metazona only. Prosternal spine conical or pyramidal, rather 

 pointed, moderately long. Tegmina brown, variably necked with dull 

 yellowish, the basal portion of the anal vein often so marked, falling 

 distinctly short of the tip of the abdomen, the costal margin somewhat 

 but not greatly expanded beyond the base, beyond tapering regularly, 

 the tip well rounded; wings at rest protruding slightly beyond the 

 tegmina. Hind femora clay yellow, thrice broadly banded with blue 

 black, the bands generally more or less blended on the outer face, the 

 whole genicular arc inky black; hind tibiae glaucous, suffused apically 

 with pale yellow, and with a narrow subbasal yellowish annulus, the 

 pallid spines black tipped, the tarsi clay yellow. Supraanal plate of 

 male triangular, the apex acute and bluntly pointed, the sides nearly 

 straight, the surface feebly arched, with a basal, triangular, apically 

 narrowing sulcus, which hardly extends to the middle of the plate and 

 is bounded by sharp walls; a short, moderately sharp but low, oblique 

 ridge starts from the outer base of the plate and runs a similar dis-
