shorter than the third joint, which is slightly longer than the fourth ;

Pronotum slightly wider than long, and subequal in width at base 

 and apex ; sides feebly constricted near base and apex, with an obtuse 

 tubercle on each side at middle; disk uneven, with a round, feebly 

 elevated tubercle at middle, and two similar tubercles arranged longi- 

 tudinally on each side ; surface nearly impunctate, with a few long, 

 inconspicuous, erect hairs. Scutellum triangular, curvilinear, and 

 densely clothed with short, recumbent, white pubescence. 



Elytra four times as long as pronotum, and at base slightly wider 

 than pronotum at middle; humeral angles broadly rounded; sides 

 nearly parallel from base to near the tips, which are separately, 

 broadly emarginate, strongly bispinose, with the lateral spine much 

 longer than the sutural one; surface sparsely, finely, irregularly 

 punctate, with a few coarser punctures intermixed, and clothed with 

 a few long, rather stiff, erect, yellowish hairs. 



Abdomen beneath sparsely, irregularly punctate, clothed with a 

 few inconspicuous, semierect hairs; last segment broadly subtrun- 

 cate at apex. Prosternum transversely, arcuately elevated anteriorly,
