  region. 
  Phoxichilidium 
  is 
  characterized 
  by 
  a 
  5- 
  or 
  6-jointed 
  oviger, 
  

   the 
  possession 
  of 
  auxiliary 
  claws, 
  and, 
  in 
  comparison 
  with 
  Anoplodac- 
  

   tylm, 
  a 
  relatively 
  shorter 
  dorsal 
  prolongation 
  of 
  the 
  cephalic 
  segment 
  

   and 
  a 
  correspondingly 
  less 
  ventral 
  origin 
  of 
  the 
  proboscis. 
  In 
  the 
  

   two 
  species 
  described 
  below, 
  however, 
  this 
  character 
  of 
  the 
  cephalic 
  

   segment 
  is 
  closer 
  to 
  Anoplodactylws 
  than 
  to 
  the 
  other 
  species 
  of 
  

   Phoxichilidium; 
  hence 
  I 
  should 
  further 
  characterize 
  Anoplodactylus 
  

   by 
  the 
  possession 
  of 
  a 
  localized 
  femoral 
  cement 
  gland 
  in 
  the 
  male, 
  

   although 
  this 
  is 
  not 
  always 
  present. 
  In 
  both 
  of 
  these 
  species 
  the 
  

   cement 
  gland 
  is 
  represented 
  by 
  a 
  row 
  of 
  pores 
  along 
  the 
  dorsal 
  surface 
  

   of 
  the 
  femur.
