 pitted ; metasternum punctulate in the middle ; inner part of anterior 

 tibias spinose at tip ; apical spur long, nearly straight.

 filled with numerous very closely set punctures, second interval 

 hardly broader than the third, humeral callus distinct ; pygidium 

 very closely and deeply pitted ; metasternum closely punctate in 

 the centre, and with the median impressed line very distinct ; inner 

 part of anterior tibiae not spinose at tip, apical spur moderately 

 slender, nearly straight in both sexes.
