  to 
  give 
  preference 
  to 
  that 
  jreniis 
  for 
  which 
  n 
  genotype 
  is 
  specified. 
  

   No 
  genotype 
  was 
  specified 
  for 
  oitlier, 
  but 
  Spilopftion 
  is 
  monobasic 
  and 
  

   Coilojieura 
  was 
  based 
  on 
  two 
  species. 
  The 
  second 
  recommendation 
  

   as 
  stated 
  applies 
  to 
  species 
  but 
  perhaps 
  may 
  also 
  be 
  interpreted 
  to 
  

   apply 
  to 
  genera. 
  It 
  is 
  that 
  a 
  "specific 
  name 
  accompanied 
  bj^ 
  both 
  

   description 
  and 
  figure 
  stands 
  in 
  preference 
  to 
  one 
  accompanied 
  only 
  

   by 
  a 
  diagnosis 
  or 
  only 
  by 
  a 
  figure." 
  Spilophioii 
  maculipennis 
  is 
  both 
  

   described 
  anil 
  figured. 
  Fur 
  the 
  above 
  reasons 
  I 
  prefer 
  to 
  use 
  Spilo- 
  

   phion 
  as 
  the 
  name 
  of 
  this 
  genus. 
  

  

  The 
  presence 
  in 
  this 
  genus 
  of 
  the 
  occipital 
  carina 
  is 
  sufficient 
  to 
  

   prove 
  Morloy's 
  error 
  in 
  synonymiziug 
  it 
  with 
  Stauropoctonus. 
  

  

  In 
  a 
  majority 
  of 
  the 
  group 
  characters 
  Spilophion 
  agrees 
  with 
  

   Enicospilus, 
  especially 
  in 
  the 
  body 
  characters, 
  but 
  differs 
  in 
  most 
  of 
  

   the 
  wing 
  characters 
  and 
  in 
  the 
  anomalous 
  hind 
  claws 
  and 
  penultimate 
  

   hook 
  of 
  the 
  frenulum. 
  

  

  Head:

   ocelli 
  large, 
  eyes 
  deeply 
  emarginate,

   across 
  clypeal 
  fovcae 
  than 
  across 
  frons; 
  clypeus 
  convex,
