to hind coxse, first joint not carinated, and slightly longer than 

 third, second about half the length of fourth, third about as 

 long as fourth and fifth combined, fifth to tenth very feebly 

 decreasing in length, eleventh slightly longer than tenth, and 

 about the length of ninth. Prothorax truncate in front, front 

 angles rather strongly rounded, sides thence feebly undulated to 

 base, a transverse impression near base, marking off a wide and 

 short median lobe, with vague remnants of a median line, aud a 

 vague foveate impression on each side of middle; punctures as 

 on head. Scutellwin with apical half polished and almost im- 

 punctate. Elytra about one-fourth wider than prothorax, and 

 about five or six times as long; with numerous distinct punctures 

 and small round granules, becoming more crowded about base; 

 striation well defined. Frosternum with moderately large punc- 

 tures, each with a central pit, on middle portion, the propleural 

 triangles with punctures much as on upper surface, but less 

 defined. Apical segment of abdomen with dense, asperate punc-

 a thin but not continuous carina). Metasternum elongate ; 

 episterna very narrow. Abdomen evenly convex, apex evenly
