A black, strongly pubescent and distinctly punctate species, with abdo- 

 minal tubercles and elongate terebra. Head hardly narrowed behind the 

 oblong and very slightly emarginate eyes; vertex somewhat broad; cly- 

 peus apically depressed and emarginate; palpi testaceous and labrum 

 usually badious; frontal and internal orbits immaculate. Antennae fili- 

 form, not apically and hardly basally attenuate, longer than half body 

 and often apically ferrugineous. Hiorax gibbous, narrower than the head, 

 longer than high, very distinctly but not closely punctate, shining and 

 pubescent; metathorax sparsely but not strongly punctate with no distinct 

 areae though the areola region is smoother with the petiolar and supra- 

 coxal very smooth and spiracles subcircular. Scutellum black, in ^ 

 rarely apically piceous. Abdomen very strongly and distinctly punctate, 

 fusiform and a little constricted towards base and apex, as broad as
