grooved along the posterior margin, covered with closely set granules, 

 and having a supra-basal transverse smooth space produced in the 

 shape of a blunt triangle the apex of which reaches to about the 

 median part, while the base does not reach the angulate part of the 

 posterior margin ; from the median part to the apex there is a very 

 narrow, smooth, longitudinal line ; elytra plane, but with the suture 

 slightly gibbose past the median part, and shining, the shoulders are 

 very slightly diagonal, the striae are very distinct and impunctate, 

 the intervals are finely shagreened and have each two series of 

 shallow but distinct punctures, the outer margin is bi-carinate ; 

 the pygidium is granulose, the metasternum is smooth in the 

 centre and has two deep impressions, the anterior one deeper 

 than the posterior, and a longitudinal narrow line interrupted in 

 the middle ; the legs are rugulose, the anterior tibiae not serrulate, 

 tri-dentate outwardly, and with a rudimentary basal tooth, inner 

 part carinate, sinuate behind and with a small tooth in a line with, 

 but under, the first outer tooth.

 the middle of the anterior part, clypeus six-dentate, the teeth sharp ; 

 prothorax convex, covered with very closely set small foveae the 

 intervals of which are slightly granulose laterally, and having a 

 narrow, median longitudinal smooth line reaching from base to apex, 

 strongly serrate laterally, and narrowly impressed along the base in 

 the median part ; elytra hardly convex, but with the suture slightly 

 raised at about the median part, slightly attenuate towards the apex, 

 humeral part a little oblique, striiB narrow, distinct, impunctate, 

 intervals with two rows of shallow but broad punctures sometimes 

 coalescing in the second interval, outer margin bi-carinate ; meta- 

 sternum with a deep, round impression between the intermediate
