  Menopon 
  robsoni, 
  sp. 
  no 
  v. 
  (fig. 
  7). 
  

  

  This 
  remarkable 
  louse, 
  named 
  after 
  Mr. 
  G. 
  C. 
  Robson, 
  of 
  the 
  Zoological 
  Depart- 
  

   ment 
  of 
  the 
  British 
  Museum, 
  was 
  brought 
  back 
  by 
  the 
  Wollaston 
  Expedition 
  to 
  

   Dutch 
  New 
  Guinea, 
  1913. 
  The 
  label 
  on 
  the 
  tube 
  endorsed 
  " 
  C. 
  B. 
  K." 
  (C. 
  Boden 
  

   Kloss) 
  conveyed 
  the 
  information 
  that 
  its 
  contents, 
  including 
  2 
  females 
  of 
  the 
  new 
  

   Menopon, 
  several 
  specimens 
  of 
  Nirmus 
  varius 
  and 
  a 
  single 
  Corvine 
  Dochophorus, 
  

   were 
  taken 
  at 
  Launch 
  Camp, 
  Setakwa 
  Kiver, 
  on 
  13th 
  March 
  1913, 
  on 
  the 
  " 
  Hawk 
  

   Crow." 
  Mr. 
  A. 
  F. 
  B. 
  Wollaston 
  kindly 
  tells 
  me 
  that 
  I 
  should 
  be 
  probably 
  correct 
  

   in 
  referring 
  this 
  to 
  Gymnocorax 
  senex 
  (Corvidae). 
  

  

  M. 
  robsoni 
  belongs 
  to 
  the 
  general 
  type 
  of 
  Carriker's 
  Colpocephalum 
  extraneum 
  

   from 
  the 
  nightjar, 
  Nyctidromus 
  albicollis 
  (Costa 
  Rica) 
  (11) 
  and 
  also 
  of 
  Kellogg's 
  

   Colpocephalum 
  sjostedti 
  from 
  Corvus 
  scapulatus 
  and 
  Corvultur 
  albicollis 
  (Africa) 
  

   (12), 
  characterised 
  by 
  the 
  development 
  of 
  pro- 
  meso- 
  and 
  meta-thorax 
  into 
  separate 
  

   thoracic 
  elements 
  (as 
  in 
  Trinoton). 
  There 
  can 
  be 
  no 
  doubt 
  that 
  these 
  two 
  species, 
  

   together 
  with 
  the 
  new 
  M 
  . 
  robsoni, 
  which 
  are 
  all 
  closely 
  related, 
  form 
  the 
  nucleus 
  of 
  

   a 
  new 
  genus 
  of 
  Mallophaga, 
  with 
  members 
  of 
  the 
  Corvidae 
  as 
  hosts.
