Palpi, antenna, and legs dark chestnut brown ; head and prothorax 

 varying from dark brown to piceous red ; elytra black with a basal 

 dorsal elongated flavescent patch, and a diagonal post-median trans- 

 verse one reaching from one median part of the disk to the other, 

 and much narrowed on each side of the suture, the posterior margin 

 has also a moderately broad band, which narrows and ascends along 

 the suture as far as the transverse dorsal band ; head very rugose, 

 pilose, and with two round tubercles at the apical part of the vertex ; 

 antennae briefly pilose, with the hairs longer on the basal joint and 

 on the inner and outer angles of the second one, joints very closely 

 set, and seemingly fused altogether ; prothorax twice as broad as 

 long, slightly sinuate in front with the sides rounded, recurved, 

 sinuate in the posterior part, with the basal angle slightly sloping 

 and penicillate, discoidal part moderately plane, and with a narrow 

 longitudinal groove ; sides depressed ; posterior part very broadly 

 excavate for nearly two-thirds of the width, and with a small tuber- 

 cular projection at each end ; elytra with the shoulders a little 

 rounded, thickly but briefly pubescent, very faintly striate, but with 

 a very well-developed basal, round costa, reaching only one-sixth of 

 the length ; pygidium punctulate, briefly pubescent, and with a thick 

 fringe of short hairs on the margins. Length 10^-lOf mm. ; width
