Front and vertex closely punctured ; a stout keel between the 

 antennae ; the face and clypeus more strongly punctured, the 

 punctures becoming larger and more confluent towards the apex of 

 the clypeus ; malar space finely, closely striated ; labrum smooth 

 and shining, deeply furrowed in the centre. Pro- and meso-thorax 

 closely and strongly punctured, the punctures round ; the metanotal 

 area strongly irregularly striated, the striae running into reticulations ; 

 the reticulated central part shorter than on the sides, the smooth 

 part continued to the apex of the segment, becoming gradually 

 narrowed, its apical half depressed, the convex upper part keeled in 

 the middle. Basal abdominal segment covered with long white, 

 slightly tinged with fulvous, hair ; the pilose bands extend on to the 

 ventral surface ; the segments are closely, minutely punctured ; the 

 apical two fuscous at the apex ; the last segment thickly covered 

 with stiff black depressed hair which gives it a striated appearance.
