   CREMNOCRYPTUS,

  Genotype. 
  — 
  Polyaenus 
  spiniferus 
  Cameron. 
  

  

  This 
  genus 
  will 
  run 
  in 
  all 
  existing 
  keys 
  to 
  {Polyaenus 
  Cresson) 
  = 
  

   Oryptanura 
  Brulle, 
  but 
  the 
  frontal 
  horns 
  are 
  of 
  quite 
  different 
  form, 
  

   being 
  flattened 
  below 
  and 
  compressed 
  above 
  and 
  separated 
  by 
  a 
  deep 
  

   groove. 
  It 
  also 
  differs 
  by 
  the 
  following 
  characters 
  : 
  Ocelli 
  situated 
  on 
  

   the 
  sides 
  of 
  a 
  distinct, 
  sometimes 
  very 
  high, 
  elevation; 
  antenna 
  in 
  

   female 
  only 
  slightly 
  thickened, 
  slightly 
  flattened 
  on 
  the 
  outer 
  upper 
  

   side 
  but 
  not 
  below; 
  occipital 
  carina 
  strongly 
  sinuate 
  at 
  lower 
  ex- 
  

   tremity; 
  mandible 
  distinctly 
  tumid 
  at 
  upper 
  basal 
  angle; 
  upper 
  

   margins 
  of 
  pronotum 
  tumid, 
  but 
  not 
  angulated 
  anteriorly 
  by 
  the 
  

   epomia, 
  which 
  are 
  weak 
  or 
  obsolete; 
  notaulices 
  shallow 
  and 
  extend- 
  

   ing 
  only 
  about 
  halfway 
  to 
  scutellum 
  ; 
  sternaulices 
  short 
  and 
  shallow 
  ; 
  

   scutellum 
  very 
  broad, 
  very 
  weakly 
  convex, 
  and 
  with 
  sparse, 
  coarse 
  

   punctures; 
  nervulus 
  interstitial 
  or 
  very 
  nearly 
  so; 
  abdomen 
  coarsely 
  

   and 
  deeply 
  punctate 
  on 
  basal 
  three 
  tergites, 
  male 
  abdomen 
  fusiform; 
  

   ovipositor 
  neither 
  distinctly 
  subsagittate 
  nor 
  swordlike, 
  but 
  rather 
  

   tapering 
  and 
  distinctly 
  flattened 
  above 
  at 
  apex. 
  

  

  CREMNOCRYPTUS 
  SPINIFERUS

  Five 
  specimens 
  of 
  each 
  sex 
  from 
  Borneo, 
  one 
  female 
  from 
  Mindanao, 
  

   and 
  two 
  females 
  and 
  one 
  male 
  from 
  Singapore 
  are 
  before 
  me. 
  These 
  

   agree 
  exactly 
  with 
  Cameron's 
  description. 
  

  

  CREMNOCRYPTUS 
  CINGULATUS 
  (Tosquinet), 
  new 
  combination 
  

  

  Polyaenus 
  cingulatus

  There 
  can 
  be 
  no 
  doubt 
  that 
  this 
  New 
  Guinea 
  species 
  is 
  congeneric 
  

   with 
  the 
  genotype. 
  A 
  considerable 
  series, 
  including 
  both 
  sexes, 
  from 
  

   Mindanao, 
  Basilan, 
  Samar, 
  and 
  Luzon 
  belong, 
  I 
  suspect, 
  to 
  the 
  species, 
  

   though 
  I 
  hesitate 
  definitely 
  to 
  identify 
  them 
  as 
  such. 
  They 
  differ 
  

   from 
  spiniferus 
  in 
  having 
  the 
  stemmaticum 
  strongly 
  elevated 
  above 
  

   the 
  ocelli 
  ; 
  the 
  thorax, 
  especially 
  the 
  posterior 
  face 
  of 
  the 
  propodeum, 
  

   much 
  more 
  sparsely 
  sculptured; 
  the 
  basal 
  tergites 
  more 
  coarsely 
  and 
  

   less 
  densely 
  punctate; 
  the 
  antennal 
  annulus 
  constantly 
  shorter; 
  and 
  

   from 
  all 
  but 
  the 
  Mindanao 
  specimen 
  in 
  the 
  blackish 
  color 
  of 
  the 
  entire 
  

   inner 
  side 
  of 
  the 
  hind 
  tibia.
