  It 
  Las 
  also 
  beeu 
  lexjorted 
  from 
  Nebraska 
  (Dodge) 
  and 
  Wyoming 
  

   (Brimer). 
  

  

  The 
  single 
  specimen 
  from 
  Grand 
  Junction 
  is 
  of 
  an 
  exceptionally 
  

   small 
  size, 
  a 
  female 
  only 
  17 
  mm. 
  long. 
  

  

  This 
  is 
  the 
  largest 
  species 
  of 
  tlie 
  genus 
  and 
  is 
  not 
  uncommon 
  at 
  the 
  

   eastern 
  base 
  of 
  the 
  Eocky 
  Mountains 
  in 
  Colorado. 
  I 
  have 
  considered 
  

   it 
  probable 
  that 
  this 
  is 
  the 
  species 
  described 
  by 
  Dodge 
  under 
  the 
  name 
  

   Cidoptenus 
  regalis, 
  but 
  the 
  description 
  does 
  not 
  very 
  well 
  apply 
  to 
  it. 
  

   I 
  am 
  guided 
  partly 
  by 
  a 
  sketch 
  of 
  the 
  markings 
  of 
  the 
  tegmina 
  sent 
  

   me 
  many 
  years 
  ago 
  by 
  Mr. 
  Dodge, 
  and 
  partly 
  by 
  the 
  impossibility 
  of 
  

   applying 
  the 
  description 
  to 
  any 
  other 
  known 
  si)ecies.

  Head 
  luteo-ferruginous, 
  with 
  a 
  broad,

  median 
  stripe 
  

   on 
  the 
  summit, 
  not 
  including 
  the 
  fastiginm;

  bright 
  

   orange. 
  Pronotum 
  obtusely

  rounded, 
  

   the 
  median 
  carina 
  generally 
  leeble 
  l)ut 
  sometimes 
  distinct 
  on 
  the 
  meta- 
  

   zona, 
  wanting 
  on 
  the

  the 
  latter 
  with 
  a 
  pair

  approximate, 
  

   anteriorly 
  converging, 
  dull 
  olivaceofuscous, 
  rather 
  obscure, 
  narrow 
  

   strij)es; 
  on 
  the 
  upper 
  half 
  of 
  the 
  lateral 
  lobes 
  the 
  transverse 
  sulci 
  are 
  

   marked 
  in

  and 
  there 
  are 
  sometimes 
  fuscous 
  clouds 
  in 
  

   the

  tapering 
  very 
  gradually, 
  the

   feebly, 
  especially 
  along 
  the 
  middle, 
  with 
  fuscous, 
  the 
  longitudinal

   interruptedly 
  fuscous

  slightly 
  

   shorter

  an 
  oblique

  on

  much 
  less 
  

   prominent;
