  species 
  of 
  Wigandia 
  (herbaceous, 
  with 
  sting- 
  

   ing 
  hairs 
  on 
  the 
  stem), 
  which 
  is 
  common 
  on 
  the 
  pass 
  between

  and 
  Zamorano.

  CENTEIS 
  (MELANOCENTRIS) 
  DURANTAE, 
  new 
  species 
  

  

  Male. 
  — 
  Length 
  about 
  9.5 
  mm.; 
  black, 
  with 
  the 
  clypeus, 
  labrum, 
  and 
  

   large 
  mark 
  on 
  mandibles 
  creamy 
  white, 
  but 
  no 
  lateral 
  marks 
  and 
  the 
  

   antennae 
  black, 
  without 
  any 
  light 
  marks 
  on 
  scape; 
  the 
  light 
  color 
  of 
  

   clypeus 
  is 
  broad 
  and 
  short, 
  broadly 
  truncate 
  above 
  ; 
  conspicuous 
  black 
  

   hair 
  at 
  sides 
  of 
  front, 
  but 
  hair 
  of 
  cheeks 
  pure 
  white; 
  a 
  triangular 
  

   patch 
  of 
  pale 
  hair 
  in 
  supraclypeal 
  region; 
  hair 
  of 
  thorax 
  above 
  hght 
  

   ferruginous, 
  beneath 
  whitish; 
  tegulae 
  ferruginous; 
  wings 
  hyaline; 
  legs 
  

   with 
  white 
  hair, 
  but 
  long 
  black 
  hair 
  on 
  posterior 
  margin 
  of 
  hind 
  tibiae 
  

   and 
  tarsi 
  ; 
  abdomen 
  shining 
  black, 
  first 
  tergite 
  with 
  white 
  hair 
  ; 
  apex, 
  

   beyond 
  fourth 
  tergite, 
  with 
  pure 
  white 
  hair. 
  This 
  looks 
  like 
  a 
  de- 
  

   pauperate 
  C. 
  ruae, 
  but 
  it 
  is 
  certainly 
  distinct. 
  The 
  clear 
  wings 
  have 
  

   paler 
  nervures, 
  and 
  the 
  venation 
  differs. 
  In 
  both, 
  however, 
  there 
  is 
  

   a 
  supplementary 
  vein 
  crossing 
  the 
  apical 
  part 
  of 
  the 
  first 
  submarginal 
  

   cell, 
  cutting 
  off 
  a 
  triangular 
  area. 
  The 
  inner 
  side 
  of 
  the 
  second 
  sub- 
  

   marginal 
  cell 
  is 
  perfectly 
  straight, 
  not 
  curved 
  as 
  in 
  C. 
  ruae.

  In 
  Friese's 
  table 
  this 
  runs 
  to 
  C. 
  minuta 
  Mocsary, 
  but 
  it 
  lacks 
  the 
  

   long 
  tooth 
  on 
  hind 
  basitarsus, 
  and 
  the 
  mandibles 
  are 
  not 
  red 
  on 
  the 
  

   middle.
