  CERATOCOMBOIDES, 
  new 
  genus 
  

  

  This 
  genus 
  is 
  distinctly 
  intermediate 
  between 
  the 
  Cryptostemma- 
  

   tinae 
  and 
  the 
  bulk 
  of 
  the 
  Schizopterinae. 
  However, 
  it 
  is 
  more 
  

   strongly 
  allied 
  to 
  the 
  latter 
  group 
  by 
  the 
  shape 
  of 
  head, 
  lack 
  of 
  costal 
  

   fracture, 
  and 
  by 
  the 
  venation. 
  The 
  latter 
  is 
  much 
  as 
  in 
  macropterous 
  

   species 
  of 
  the 
  genus 
  Schizoptera 
  (fig. 
  44), 
  but 
  the 
  veins 
  are 
  about 
  

   equally, 
  though 
  moderately, 
  elevated 
  throughout, 
  the 
  radius 
  being 
  

   no 
  more 
  conspicuously 
  raised 
  than 
  the 
  others. 
  The 
  pronotum 
  has 
  a 
  

   distinct 
  impressed 
  line 
  near 
  anterior 
  margin; 
  the 
  eyes 
  are 
  higher 
  

   than 
  long 
  (fig. 
  15) 
  ; 
  and 
  ocelli 
  are 
  present. 
  The 
  abdomen 
  of 
  male 
  

   has 
  6 
  visible 
  ventral 
  segments.

  CERATOCOMBOIDES 
  PRIMA, 
  new 
  species 
  

  

  Male. 
  — 
  Yellowish-brown, 
  slightly 
  shining, 
  the 
  legs 
  stramineous. 
  

   Dorsum 
  of 
  head, 
  pronotum, 
  and 
  veins 
  of 
  corium 
  with 
  pale 
  decumbent 
  

   hairs. 
  Space 
  between 
  eyes 
  at 
  vertex 
  about 
  3 
  times 
  as 
  wide 
  as 
  either 
  

   eye; 
  head 
  broadly 
  rounded 
  in 
  front 
  when 
  seen 
  from 
  above; 
  ocelli 
  

   rather 
  large 
  ; 
  head 
  and 
  thorax 
  from 
  side 
  as 
  in 
  figure 
  15. 
  Impressed 
  

   transverse 
  line 
  on 
  pronotum 
  slightly 
  convex 
  posteriorly 
  ; 
  hind 
  margin 
  

   of 
  pronotum 
  a 
  little 
  concave 
  ; 
  apex 
  of 
  scutellum 
  somewhat 
  produced 
  

   but 
  not 
  visibly 
  notched 
  ; 
  thorax 
  more 
  depressed 
  than 
  in 
  other 
  genera, 
  

   the 
  pleura 
  nearly 
  horizontal. 
  Hypopygium 
  with 
  a 
  long 
  curled 
  proc- 
  

   ess 
  as 
  in 
  Schizoptera, 
  but 
  the 
  hypopygium 
  is 
  clearly 
  visible 
  from 
  

   below 
  ; 
  5th 
  sternite 
  longer 
  than 
  hypopygium. 
  Venation 
  of 
  f 
  orewing

  Reuter 
  divided 
  the 
  genus 
  Schizoptera 
  into 
  three 
  subgenera, 
  8 
  

   later 
  9 
  proposing 
  generic 
  rank 
  for 
  one 
  of 
  them, 
  Corixidea. 
  We 
  treat 
  

   all 
  of 
  his 
  segregates 
  as 
  genera 
  and 
  further 
  subdivide 
  the 
  genus 
  

   Schizoptera, 
  as 
  thus 
  restricted, 
  into 
  seven 
  subgenera 
  as 
  indicated 
  in 
  

   the 
  following 
  key.
