Undamaged specimens of Metoponorthus priuinosus are of a 
beautiful bluish-grey colour, owing to a ‘‘ bloom” which is 
easily brushed off, revealing a dark reddish- 
brown tint beneath it. The antenne are long 
and have white markings upon them. 
Air-tubes occur in the first two abdominal 
appendages.
