 aiitennal Joint; fastijj^ium ratiier steeply deelivent, shallowly and 

 broadly (male) or scarcely (female) sulcate; frontal costa fadinj; just 

 before the clypens, e^jinil, slightly narrowei' than the inters|)ace between 

 the eyes, faintly depresse<l at the ocellus, nowhere sulcate, rather 

 sparsely punctate thioughout, biseriately and more heavily above; eyes 

 moderately large, not prominent, anteriorly subtrun(;ate, a little (nude) 

 or scarcely (female) longer than the intraocular portion of the genae; 

 antennae rufous, sometimes feebly infuscated apically, fully two thirds 

 (unde) or a little more than half (fenude) as long as the hind f(imora. 

 Pronotum snbequal, slightly eidarging ])osteriorly on the posterior 

 half, the sides with a broad postocular ]>ieeous band confined to the 

 prozona, less conspicucms in the female than in the male and often 

 broken, the disk rather broadly convex and i>as8ing into the interiorly 

 vertical lateral lobes by a well rounded slumlder, occasionally showing a 

 blunt angulation; median carina distinct on the metazona, generally 

 very feeble on the i)rozona and often subobsolete between the sulci; 

 front margin truncate, hind margin very broadly convex, occasionally sub

 Tegmina about as long as the pronotum, subattingent, ovate, apically 

 bluntly acuminate, utmost twice as long as broad, ferrugineo-fuscous. 

 Fore and middle femora considerably tumid in the male; hind femora 

 rather long, not very slender, testaceous, more or less but generally much

 bifasciate with fuscous, the lower face and lower balf of inner face 

 fiavous, the geniculacion more or less infuscated ; hind tibiae sordid pale 

 olivaceous, with a fuscous patellar annulus, the spines black nearly 

 from the base, eleven to twelve, rarely ten, in number in the outer series. 

 Extremity of male abdomen considerably clavate, much recurved, the 

 supraanal plate subtriangular with rectangulate apex, the lateral mar-
