I have not included this species in the key to the females, 

 because it is known only in the male sex. It seems to be 

 most nearly allied to biviitatus, but the orange bands at the 

 base of the'second and fourth dorsal segments are narrow 

 and that ou the second interrupted; the angles of the pro- 

 notum are also more distinctly pointed and the first abdo- 

 minal segment is broader and shorter.
