  If 
  all 
  the 
  pemphilidine 
  wasps 
  were 
  to 
  be 
  placed 
  in 
  one 
  blanket 
  

   genus 
  Crabro, 
  as 
  Arnold 
  proposes, 
  it 
  would 
  be 
  necessary 
  to 
  rename 
  

   this 
  species 
  inasmuch 
  as 
  it 
  would 
  then 
  be 
  a 
  homonym 
  of 
  Taschenberg's 
  

   1875 
  Venezuelan 
  species 
  and 
  also 
  Provancher's 
  1882 
  Canadian 
  form.

  The 
  superficial 
  habitus 
  of 
  hndwelli 
  is 
  very 
  similar 
  to 
  that 
  of 
  Tur- 
  

   ner's 
  Natal 
  I'ugo 
  so 
  punctata^ 
  from 
  which 
  it 
  may 
  be 
  differentiated 
  by 
  

   the 
  variolate 
  sculpture 
  of 
  the 
  scutellum 
  and 
  the 
  narrower 
  front. 
  In 
  

   addition, 
  the 
  postorbital 
  carinule 
  of 
  hridwelli 
  is 
  not 
  continuous 
  onto 
  

   the 
  vertex 
  and 
  the 
  recurrent 
  vein 
  of 
  the 
  fore 
  wing 
  is 
  received 
  by 
  the 
  

   submarginal 
  cell 
  three-fifths 
  of 
  the 
  way 
  from 
  its 
  base, 
  whereas 
  in 
  

   rugosopwnctata 
  the 
  postorbital 
  carinule 
  is 
  continuous 
  dorsally 
  on 
  the 
  

   vertex 
  while 
  the 
  recurrent 
  vein 
  is 
  received 
  by 
  the 
  submarginal 
  cell 
  

   only 
  two-fifths 
  of 
  the 
  way 
  from 
  its 
  base.
