  With 
  the 
  exception 
  of 
  Golofa 
  guildinii, 
  attributed 
  to 
  the 
  

   West 
  Indies, 
  the 
  species 
  of 
  the 
  genus 
  are 
  confined 
  to 
  the 
  

   mountain 
  chain 
  of 
  Central 
  and 
  Western 
  S. 
  America, 
  and 
  

   the 
  present 
  one, 
  with 
  G. 
  cochlearis, 
  Ohaus, 
  also 
  lately 
  

   discovered 
  in 
  the 
  Argentine, 
  seem 
  to 
  mark 
  the 
  farthest 
  

   southward 
  extension 
  of 
  the 
  genus. 
  It 
  is 
  a 
  shining 
  insect, 
  

   with 
  the 
  thorax 
  of 
  the 
  male 
  very 
  smooth 
  and 
  not 
  bearing 
  a 
  

   vertical 
  horn, 
  but 
  with 
  a 
  circular 
  cavity 
  filled 
  with 
  velvety- 
  

   pubescence 
  and 
  its 
  upper 
  edge 
  slightly 
  produced 
  in 
  a 
  

   horizontal 
  direction. 
  

  

  The 
  British 
  Museum 
  contains 
  two 
  males 
  and 
  a 
  female 
  

   which, 
  although 
  not 
  taken 
  together 
  with 
  either 
  of 
  the 
  males, 
  

   is 
  almost 
  certainly 
  conspecific.
