  A 
  male 
  specimen, 
  evidently 
  named 
  by 
  Walker, 
  is 
  in 
  the 
  

   British 
  Aluseum. 
  It 
  answers 
  well 
  to 
  Walker's 
  description, 
  

   and 
  may 
  possibly 
  be 
  the 
  type.

  Very 
  near 
  Iwtus, 
  Klug, 
  but 
  the 
  depression 
  on 
  the 
  middle 
  of 
  

   the 
  median 
  segment 
  is 
  narrower 
  and 
  not 
  so 
  deep, 
  and 
  the 
  

   transverse 
  ridge 
  on 
  the 
  second 
  ventral 
  segment 
  of 
  the 
  male 
  is 
  

   much 
  less 
  developed. 
  The 
  scutellum 
  in 
  the 
  male 
  is 
  yellow, 
  

   as 
  in 
  the 
  female.
