 pronotum, and scutellum black; elytra pale yellow, vitreous, with 

 the lateral and sutural margins and the base broadly black ; beneath 

 black, with the bases of the posterior tibiae and femora broadly pale 

 yellow. 



Head with the front rather long, and flat between the eyes; sur- 

 face glabrous, coarsely, irregularly punctate, and longitudinally 

 rugose on the front, becoming coarsely, confluently punctate on the 

 occiput. Eyes separated from each other on the front by about the 

 width of the labrum. Antennae short, robust, extending to base of 

 first abdominal segment, and with the intermediate joints widest; 

 joints 1 to 3 shining, coarsely punctate, and the third densely pubes- 

 cent, the following joints subopaque, densely pubescent, and some 

 of the joints armed with long, erect hairs on the inner margin; joint 

 1 robust, slightly arcuate, and rather strongly clavate; joints 2 to 

 4 subcylindrical, the third twice as long as the fourth, which is 

 slightly more robust; joints 5 to 10 strotigly serrate, the outer 

 anterior angle of the joints acute, and the joints becoming narrower 

 and shorter toward tip of antennae; joint 11 oblong and acute at 

 apex. 



Pronotum distinctly longer than wide, the sides feebly arcuately 

 rounded in front, and broadly arcuately constricted behind the middle, 

 the anterior margin strongly elevated ; disk strongly convex, without 

 tubercles or carinae; surface coarsely, transversely rugose, coarsely, 

 irregularly punctate between the rugae, and clothed with a few 

 inconspicuous erect hairs. Scutellum densely clothed at apex with 

 long, recumbent cinereous pubescence, which conceals the surface. 



Elytra extending to apex of third abdominal segment, the tips 

 broadly subtruncate or obtusely rounded, the sutural margins feebly 

 elevated, slightly narrowed, and slightly dehiscent posteriorly; 

 surface glabrous, with the black areas coarsely, confluently punctate, 

 becoming somewhat scabrous in basal region, and the vitreous area 

 coarsely, obsoletely punctate. 



Abdomen beneath shining, very sparsely, finely punctate, and 

 clothed with a few inconspicuous erect hairs. Sternum sparsely 

 clothed with long, erect hairs on posterior half, and the anterior half 

 densely clothed with short, recumbent cinereous pubescence. An- 

 terior and middle legs short, the femora strongly abruptly clavate. 

 Posterior legs moderately long, clothed with long, erect black hairs, 

 the femora strongly clavate, and the tibiae straight and cylindrical.
