 basali modice sinuata, angulis fere rectis ; eh/tris prouoto latioribus, plus quam

 antennis testaceis, clavis infuscatis, valde incrassatis. 



Bodi/ subhemispheric, very smooth and shining, faintly- punctured, deep black, with 



the whole anterior margin of the thorax broadl}^ transparent white. 

 Head dusky-testaceous ; eyes large and prominent ; palpi large, yellow ; antennse
