 of the mesonotum, strongly punctured, the middle on the 

 basal part smooth and shining, the smooth part slightly 

 depressed in the middle at the base; the postscutellura finely 

 rugose. Median segment reticulated, the apex more closely 

 below, its upper part more irregularly and with a keel down 

 the middle ; the reticulations on the basal half are large and 

 irregular; the central area is wide, slightly widened at the

 slightly different angle from the lower. Abdomen ferru-

 the penultimate segment piceous black ; the petiole is strongly 

 but not closely punctured ; the ventral keel is slightly roundly
