Head sparsely, coarsely punctate, densely clothed with long, recum- 

 bent, white and brownish-yellow hairs intermixed, which conceal the 

 surface, front distinctly wider than long, with a longitudinal costa 

 on vertex, broadly concave between the antennal tubercles, which are 

 widely separated and slightly elevated; eyes deeply emarginate, 

 separated from each other on the top by nearly three times the width 

 of the upper lobe. Antenna one and one-half times as long as the 

 body, basal joints sparsely, coarsely punctate, rather densely clothed 

 with long, recumbent, white and brownish-yellow hairs intermixed, 

 with a few long, erect hairs on the underside of the joints, apical 

 joints densely, finely punctate, and densely clothed with short, re- 

 cumbent, white pubescence, joints 3 to 5 unispinose at apices; first 

 joint robust, strongly clavate, subequal in length to the third joint, 

 which is distinctly longer than the fourth, the following joints 

 subequal in length to the third ; eleventh joint slender, and slightly 

 longer than the tenth. 



Pronotum distinctly wider than long, and about equal in width 

 at base and apex; sides feebly, arcuately rounded, and subtuber- 

 culate at middle; disk somewhat uneven, and ornamented with 

 glabrous spots as follows: A narrow, longitudinal, median vitta, 

 extending from anterior margin to base, and three glabrous tuber- 

 cles on each side, one at base, and two placed transversely in front 

 of middle, of which the outer tubercle is the longest; surface 

 coarsely, irregularly punctate, densely clothed with long, recumbent, 

 white and brownish-yellow pubescence, which conceals the surface. 

 Scutellum broadly triangular, curvilinear, glabrous at middle, and 

 clothed at sides with long, recumbent hairs. 



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

 than pronotum at middle; humeral angles broadly rounded; sides 

 vaguely narrowed from base to the tips, which are separately, deeply 

 emarginate, bispinose, with the lateral spine much longer than the 

 sutural one; surface coarsely, confluently punctate, the punctures 

 finer and distinctly separated toward the apices, rather densely 

 clothed with moderately long, recumbent, brownish-yellow hairs, with 

 numerous short, recumbent white hairs intermixed, and each elytron 

 ornamented with a glabrous costa behind the middle, and an incon- 

 spicuous, elongate spot of dense, white pubescence in front of middle. 



Abdomen beneath sparsely, finely punctate, densely clothed with 

 long, recumbent, brownish-yellow and white pubescence, with a few 

 long, erect hairs intermixed, median part of segments more sparsely 

 pubescent; last segment broadly rounded and vaguely emarginate at 

 apex. Prosternum rather finely, densely pubescent, except on pro- 

 sternal process and along anterior margin ; prosternal process rather 

 broad, slightly expanded toward apex, which is truncate, and
