  This 
  species 
  seems 
  to 
  be 
  confined 
  to 
  Baja 
  California. 
  I 
  have 
  seen 
  

   specimens 
  from 
  Santa 
  Rosa 
  (Gus 
  Boycr) 
  and 
  Cape 
  San 
  Ijucas 
  (Horn). 
  

  

  Remarks. 
  — 
  Eupagoderes 
  lucanus 
  Horn 
  is 
  set 
  apart 
  from 
  all 
  the 
  others 
  

   of 
  the 
  genus 
  by 
  the 
  brown 
  color, 
  the 
  elongate 
  rostrum, 
  the 
  equal 
  

   basal 
  joints 
  of 
  the 
  antennal 
  funicle, 
  and, 
  above 
  all, 
  by 
  the 
  extraor- 
  

   dinary 
  development 
  of 
  the 
  female 
  eighth 
  sternite 
  into 
  two 
  large 
  

   teeth, 
  curving 
  downward, 
  a 
  character 
  that 
  is 
  as 
  peculiar 
  in 
  Eupago- 
  

   deres 
  as 
  is 
  the 
  female 
  genitalic 
  structure 
  of 
  symmetricus 
  Fall 
  in 
  the 
  

   genus 
  Ophryasies. 
  

  

  One 
  specimen 
  examined 
  has 
  large 
  subsidiary 
  median 
  sulci 
  upon 
  

   the 
  rostrum, 
  the 
  base 
  of 
  the 
  rostrum 
  being 
  5-sulcate, 
  and 
  the
