  Type. 
  — 
  Female 
  adult 
  from 
  Cypseloides 
  jumigatus 
  (Streubel) 
  

   collected 
  by 
  the 
  author 
  on 
  Kio 
  Esmeralda, 
  Department 
  of 
  C6rdoba, 
  

   Colombia, 
  May 
  19, 
  1949 
  (in 
  USNM). 
  

  

  Diagnosis. 
  — 
  The 
  general 
  shape 
  of 
  the 
  head 
  resembles 
  very 
  much 
  

   that 
  of 
  D. 
  gossei 
  Thompson, 
  although 
  the 
  temples 
  are 
  perfectly 
  

   straight 
  on 
  posterior 
  margin, 
  but 
  the 
  measurements 
  of 
  the 
  body 
  are 
  

   very 
  different, 
  2.80 
  by 
  1.02 
  against 
  2.30 
  by 
  .81 
  for 
  gossei. 
  

  

  Unfortunately 
  the 
  type, 
  and 
  only 
  specimen, 
  is 
  in 
  poor 
  condition, 
  

   having 
  been 
  cleared 
  too 
  much 
  and 
  having 
  collected 
  within 
  the 
  head 
  

   and 
  thorax 
  a 
  quantity 
  of 
  food 
  particles 
  which 
  obscure 
  the 
  few 
  visible 
  

   details 
  of 
  internal 
  structure. 
  

  

  The 
  whole 
  thorax 
  and 
  abdomen 
  are 
  of 
  normal 
  shape 
  and 
  structm-e, 
  

   presenting 
  no 
  outstanding 
  characters. 
  The 
  chaetotaxy 
  of 
  the 
  head 
  

   is 
  also 
  normal, 
  except 
  for 
  the 
  three 
  dorsal 
  spines 
  which 
  are 
  present 
  in 
  

   but 
  few 
  species. 
  The 
  prosternal 
  plate 
  is 
  unusually 
  large, 
  very 
  broad 
  

   anteriorly, 
  and 
  with 
  wide 
  marginal 
  band. 
  There 
  is 
  a 
  long, 
  slender 
  

   seta 
  at 
  each 
  anterior 
  corner 
  of 
  the 
  clear 
  area 
  and 
  11 
  heavy, 
  short 
  

   spines 
  irregularly 
  set 
  within 
  it. 
  There 
  are 
  numerous 
  heavy 
  spines 
  

   on 
  the 
  mesosternum, 
  those 
  beneath 
  the 
  posterior 
  portion 
  of 
  the 
  

   prothorax 
  being 
  thicker 
  than 
  the 
  patch 
  on 
  the 
  posterior 
  margin 
  of 
  the 
  

   mesosternum. 
  

  

  The 
  spines 
  along 
  posterior 
  margin 
  of 
  the 
  tergites 
  are 
  thick 
  and 
  

   closely 
  set, 
  interspaced 
  irregularly 
  with 
  long 
  setae, 
  usually 
  2 
  to 
  3 
  

   spines 
  between 
  the 
  long 
  hairs: 
  there 
  is 
  but 
  one 
  longish 
  hair 
  at 
  the 
  

   posterolateral 
  angle 
  of 
  tergites 
  II 
  to 
  VII. 
  Short, 
  thick 
  setae 
  are 
  

   scattered 
  irregularly 
  over 
  the 
  sternites, 
  while 
  the 
  patches 
  of 
  setae 
  on 
  

   sternites 
  V 
  and 
  VI 
  are 
  sparse 
  and 
  coarse, 
  as 
  well 
  as 
  those 
  on 
  the 
  third 
  

   femora; 
  there 
  are 
  an 
  unusual 
  number 
  of 
  short, 
  thick 
  spines 
  along 
  the 
  

   outer 
  edge 
  of 
  the 
  second 
  and 
  third 
  femora, 
  and 
  the 
  spines 
  along 
  pos- 
  

   terior 
  edge 
  of 
  ventral 
  pleurites 
  are 
  unusually 
  numerous 
  and 
  thickened. 
  

   The 
  peculiar 
  median 
  sternal 
  plate 
  usually 
  present 
  on 
  segment 
  I 
  of 
  

   abdomen 
  seems 
  to 
  be 
  absent, 
  at 
  least 
  it 
  is 
  not 
  visible.
