Front coarsely rugosely punctured, the punctures running 
into reticulations in parts; its centre is furrowed; the furrow is 
punctured on either side, the punctured band becoming wider 
towards the apex. On the smooth part of the vertex, at the 
apex, is a deep transverse furrow ; behind, in the centre, is a 
narrower, shallower longitudinal furrow. Face irregularly 
longitudinally striated ; the clypeus is piceous ; its apex is broad- 
ly roundly incised. Mandibles opaque, sparsely punctured ; 
their teeth are smooth and shining, large and broadly rounded. 
Thorax coarsely rugosely punctured: the pleure more coarsely 
than the mesonotim and more or less reticulated ; the propleure 
smooths and with the central] depression bearing some stout
