  rufous, 
  sometimes 
  feebly 
  infuscated

  band 
  confined 
  to 
  the 
  

   prozona, 
  less 
  conspicuous 
  in

  than 
  in 
  the

  and 
  often 
  

   broken,

  rather 
  broadly 
  convex 
  and

  occasionally 
  showing 
  a 
  

   blunt 
  angulation; 
  median 
  carina 
  distinct 
  on

  less 
  infuscated

   gins 
  strongly 
  elevated 
  in 
  the 
  basal 
  half, 
  the 
  median 
  sulcus 
  moderately 
  

   deep,
