Male : Bronze on the upper side, dark cyaneous underneath ; 

 clypeus semicircular with the margin slightly recurved, slightly 

 sinuate laterally at the junction with the gense, and a little emar- 

 ginate at tip, rugosely plicate, the head is very scahrose, and has 

 an ill-defined, short, frontal carina, the vertex is produced in a 

 short, compressed, truncate median tubercle slightly emarginate in 

 the centre ; prothorax ampliate laterally, marginate in front and on 

 the sides as well as in the median part of the base which is slightly 

 aculeate while the sides from the outer angle to about one-third of 

 the width are compressed in such a way that the adjoining part 

 of the disk overhangs it slightly, moderately convex, somewhat 

 declivous in front, but not scooped, depressed longitudinally in 

 the middle from the median part to the base, covered with very 

 closely set granules of equal size, and very briefly pubescent ; 

 elytra ampliate below the humeral angle, rounded laterally and 

 gradually attenuate behind, striae narrow, geminate, remotely punc- 

 tured, intervals between the striae plane, filled with very distinct, 

 equi-distant, closely set granules, third interval as broad as the 

 second ; pygidium deeply but not closely pitted ; legs and meta- 

 sternum roughly punctured, the latter has a faintly impressed 

 median longitudinal line ; anterior tibiae very distinctly bent inwardly 

 from the penultimate outer tooth, with the apical part dilated 

 inwardly in a tooth nearly as long as the outer apical one, spur 

 somewhat thick, sharp at tip, and nearly straight.
