  Coelopacidia, 
  Enderlein, 
  1911. 
  

  

  This 
  genus 
  was 
  placed 
  by 
  its 
  author 
  near 
  Acidia, 
  while 
  in 
  Prof. 
  Hendel's 
  table 
  

   it 
  comes 
  near 
  Platyparea. 
  I 
  have 
  before 
  me 
  two 
  species, 
  which 
  agree 
  in 
  the 
  form 
  

   of 
  the 
  body 
  and 
  head, 
  and 
  in 
  the 
  reduced 
  wing 
  pattern, 
  with 
  the 
  description 
  of 
  Dr. 
  

   Enderlein 
  ; 
  but 
  the 
  author 
  has 
  not 
  described 
  the 
  chaetotaxy, 
  which 
  is 
  very 
  reduced 
  

   in 
  the 
  species 
  before 
  me. 
  

  

  The 
  systematic 
  position 
  of 
  the 
  genus 
  is 
  dubious. 
  In 
  the 
  want 
  of 
  prst., 
  dc, 
  prscl. 
  

   and 
  st. 
  it 
  agrees 
  with 
  the 
  Dacinae 
  and 
  Adraminae, 
  but 
  differs 
  from 
  them 
  in 
  the 
  

   presence 
  of 
  the 
  hm. 
  Owing 
  to 
  this 
  last 
  character, 
  the 
  presence 
  of 
  distinct 
  ocp. 
  and 
  

   to 
  the 
  presence 
  of 
  bristles 
  on 
  the 
  underside 
  of 
  the 
  front 
  femora, 
  I 
  prefer 
  to 
  locate 
  

   the 
  genus 
  at 
  the 
  beginning 
  of 
  the 
  Ceratitinae, 
  as 
  a 
  connecting 
  link 
  between 
  this 
  

   subfamily 
  and 
  the 
  Adraminae. 
  

  

  I 
  have 
  not 
  seen 
  the 
  genotype, 
  C. 
  madagascariensis, 
  End., 
  but 
  I 
  will 
  give 
  here 
  a 
  

   characterisation 
  of 
  the 
  genus 
  drawn 
  from 
  the 
  two 
  continental 
  species 
  at 
  hand. 
  

  

  Head 
  in 
  front 
  view 
  about 
  as 
  broad 
  as 
  high, 
  not 
  broader 
  than 
  the 
  thorax 
  ; 
  occiput 
  

   convex 
  and 
  prominent, 
  with 
  developed 
  but 
  not 
  sharply 
  differentiated 
  lower 
  swellings 
  ; 
  

   neck 
  inserted 
  just 
  below 
  the 
  middle 
  of 
  the 
  occiput, 
  which 
  bears 
  a 
  tubercle 
  above 
  it. 
  

   Frons 
  distinctly 
  concave 
  in 
  the 
  middle, 
  parallel- 
  sided, 
  about 
  twice 
  as 
  long 
  as 
  broad 
  ; 
  

   lunula 
  very 
  narrow 
  and 
  not 
  extended 
  at 
  sides. 
  In 
  profile 
  the 
  eyes 
  are 
  much 
  rounded, 
  

   their 
  vertical 
  diameter 
  being 
  only 
  a 
  little 
  longer 
  than 
  the 
  horizontal 
  one 
  ; 
  they 
  are 
  

   higher 
  above 
  than 
  the 
  middle 
  of 
  the 
  hollowed 
  frons, 
  while 
  in 
  front 
  the 
  frons 
  is 
  promin- 
  

   ent 
  as 
  a 
  distinct 
  conical 
  protuberance, 
  which 
  bears 
  the 
  antennae. 
  Face 
  deeply 
  

   hollowed 
  in 
  the 
  middle, 
  without 
  median 
  keel 
  and 
  with 
  undifferentiated 
  antennal 
  

   grooves, 
  but 
  distinctly 
  prominent 
  below 
  at 
  the 
  mouth-border 
  ; 
  cheeks 
  linear 
  ; 
  

   jowls 
  as 
  broad 
  as 
  the 
  breadth 
  of 
  the 
  third 
  antennal 
  joint. 
  Antennae 
  inserted 
  at 
  

   middle 
  of 
  the 
  eyes 
  ; 
  in 
  consequence 
  of 
  the 
  protuberance 
  of 
  the 
  fore 
  part 
  of 
  the 
  frons 
  

   and 
  of 
  the 
  excavation 
  of 
  the 
  face, 
  they 
  are 
  rather 
  porrect 
  ; 
  third 
  joint 
  rounded 
  

   at 
  tip, 
  bare, 
  not 
  reaching

  long, 
  thin,

  thick 
  ; 
  palpi 
  less

  ; 
  one 
  s. 
  or., 
  erect 
  and 
  directed 
  backwards, 
  placed 
  near

  the 
  frons, 
  at 
  the 
  front 
  end 
  of 
  the 
  long 
  narrow 
  curved 
  ill-differentiated 
  

   vertical 
  plates 
  ;
