  This 
  species 
  is 
  well 
  described 
  and 
  figured 
  by 
  the 
  author 
  and 
  needs 
  

   little 
  comment 
  beyond 
  the 
  characters 
  given 
  in 
  the 
  key. 
  The 
  occipital 
  

   margin 
  is 
  deeply 
  reentering, 
  with 
  occiput 
  strongly 
  convex; 
  the 
  shape 
  

   of 
  the 
  gular 
  plate 
  also 
  seems 
  to 
  be 
  characteristic; 
  the 
  temples 
  are 
  

   very 
  flatly 
  convex 
  and 
  the 
  prosternal 
  plate 
  characteristic 
  with 
  its 
  

   straight, 
  converging 
  sides, 
  narrow 
  borders, 
  and 
  three 
  very 
  long 
  setae 
  

   (almost 
  as 
  long 
  as 
  plate), 
  two 
  in 
  marginal 
  band 
  and 
  one 
  in 
  clear 
  area.

  distinctus 
  Ferris, 
  Canadian 
  Ent., 
  vol. 
  48, 
  p. 
  310, 
  1916. 
  (Host, 
  Callocalia 
  

   sp. 
  from 
  Java.) 
  

  

  A 
  single 
  male 
  of 
  this 
  interesting 
  species 
  was 
  collected 
  by 
  R. 
  H. 
  Baker 
  

   from 
  Callocalia 
  inexpectata 
  bartschi 
  Mearns 
  on 
  the 
  Island 
  of 
  Guam 
  on 
  

   July 
  29, 
  1945. 
  This 
  specimen 
  was 
  previously 
  reported 
  on 
  and 
  figured 
  

   by 
  the 
  author 
  (Proc. 
  U. 
  S. 
  Nat. 
  Mus., 
  vol. 
  100, 
  p. 
  16, 
  1949). 
  

  

  D. 
  distinctus 
  is 
  probably 
  the 
  most 
  abnormal 
  species 
  of 
  the 
  genus 
  as 
  

   regards 
  the 
  shape 
  of 
  the 
  head, 
  which 
  is 
  about 
  as 
  long 
  as 
  wide, 
  with 
  a 
  

   wide, 
  transverse 
  frons 
  and 
  sides 
  of 
  pre-antennary 
  area 
  straight 
  and 
  

   slightly 
  divergent. 
  The 
  meso-metathoracic 
  suture 
  is 
  faintly 
  visible, 
  

   but 
  the 
  two 
  segments 
  are 
  very 
  closely 
  united 
  (this 
  detail 
  omitted 
  in 
  

   my 
  figure 
  in 
  paper 
  cited 
  above).

  (Host, 
  

   Hirundapis 
  c. 
  caudacutus 
  (Latham).) 
  

  

  A 
  new 
  genus 
  was 
  erected 
  by 
  Uchida 
  for 
  this 
  species 
  on 
  the 
  strength 
  

   of 
  the 
  shape 
  of 
  abdominal 
  segments 
  VIII 
  and 
  IX 
  in 
  both 
  sexes 
  and 
  

   the 
  male 
  genitalia. 
  Segment 
  IX 
  is 
  very 
  small 
  (especially 
  in 
  the 
  male) 
  

   and 
  enclosed 
  within 
  a 
  deep 
  emargination 
  of 
  the 
  posterior 
  margin 
  of
