   more

  Axinopalpus 
  humeralis, 
  Solier 
  {Variopalpis, 
  id.), 
  has 
  a 
  

   similar 
  exserted 
  head, 
  but 
  differs 
  in 
  its 
  oblong-quadrate 
  

   elytra, 
  like 
  all 
  other 
  species 
  of 
  the 
  same 
  genus. 
  With 
  

   regard 
  to 
  the 
  form 
  of 
  the 
  thorax, 
  Axinopalpus 
  brevicollis, 
  

   Germ., 
  and 
  A. 
  hrunneus, 
  Chaud., 
  approach 
  closely 
  our 
  

   new 
  genus. 
  In 
  the 
  form 
  of 
  the 
  head 
  and 
  elytra, 
  Xeno- 
  

   dromius 
  recalls 
  forcibly 
  the 
  Brachinus 
  type.
