  Chaetotaxy, 
  Male 
  and 
  Female. 
  — 
  Along 
  the 
  temporal 
  margin 
  of 
  the 
  head 
  are 
  two 
  

   widely 
  spaced 
  hairs 
  ; 
  in 
  H. 
  tuberculatus 
  there 
  are 
  3 
  or 
  4 
  moderately 
  long 
  hairs 
  in 
  

   this 
  position 
  fairly 
  close 
  together. 
  On 
  the 
  abdomen, 
  the 
  lower 
  side 
  of 
  each 
  pleural 
  

   angle 
  possesses 
  2 
  small 
  hairs 
  ; 
  in 
  H. 
  tuberculatus 
  in 
  the 
  same 
  position 
  there 
  is 
  a 
  row 
  

   of 
  9 
  or 
  10 
  closely 
  placed 
  hairs. 
  

  

  Mouthparts. 
  — 
  In 
  fig. 
  1 
  d, 
  will 
  be 
  found 
  the 
  pair 
  of 
  structures 
  lying 
  one 
  on 
  each 
  side 
  

   of 
  the 
  pharynx 
  inside 
  the 
  head 
  called 
  by 
  Enderlein 
  (7) 
  mandibles. 
  It 
  is 
  not 
  possible 
  

   here 
  to 
  enter 
  upon 
  the 
  much-discussed 
  question 
  of 
  the 
  homologies 
  of 
  the 
  Anopluran 
  

  

  J*CR

  mouthparts 
  and 
  particularly 
  of 
  the 
  needle-like 
  trophi 
  used 
  by 
  these 
  blood-sucking 
  

   insects 
  for 
  piercing 
  the 
  skin. 
  But 
  the 
  opportunity 
  is 
  taken 
  to 
  point 
  out 
  that 
  the 
  

   " 
  mandibles 
  " 
  are 
  well 
  developed 
  and 
  quite 
  visible 
  through 
  the 
  integument 
  without 
  

   the 
  aid 
  of 
  dissection. 
  The 
  chitinisation 
  of 
  the 
  pharynx 
  is 
  very 
  complex. 
  The 
  

   fulturae 
  are 
  small.
