  nates 
  iu 
  a 
  tubercle 
  distinct 
  from 
  the 
  margin 
  itself, 
  tliough 
  it 
  is 
  a 
  ratlier 
  

   common 
  feature 
  in 
  the 
  alternate 
  section; 
  accordingly 
  I 
  liave 
  arranged 
  

   these 
  two 
  genera 
  in 
  such 
  an 
  order 
  that 
  they 
  directly 
  follow 
  those 
  of 
  the 
  

   other 
  section, 
  and 
  the 
  remaining 
  genera 
  in 
  such 
  sequence 
  as 
  that 
  

   arrangement 
  required. 
  It 
  is 
  composed 
  of 
  insects 
  of 
  a 
  much 
  heavier 
  

   build 
  than 
  HespcrotetUx, 
  the 
  principal 
  distinctions 
  between 
  the 
  two 
  

   genera 
  being 
  given 
  in 
  the 
  table 
  (page 
  11). 
  

  

  The 
  genus 
  is 
  confined 
  to 
  the 
  western 
  half 
  of 
  the 
  United 
  States 
  from 
  

   the 
  Yellowstone 
  to 
  the 
  Mexican 
  border/ 
  but 
  it 
  does 
  not 
  appear 
  to 
  have 
  

   been 
  found 
  in 
  California'^ 
  or 
  farther 
  east 
  than 
  western 
  Kansas 
  and 
  

   Kobraska; 
  it 
  does 
  not 
  reach 
  the 
  prairie 
  region, 
  and 
  is 
  mostly 
  found 
  

   apparently 
  at 
  elevations 
  not 
  far 
  from 
  3,000 
  to 
  6,000 
  feet 
  above 
  the 
  sea. 
  

  

  According 
  to 
  Bruner, 
  Acoloplus 
  tHrnhiiUil 
  and 
  Aeoloplus 
  vhe)wpo(lii, 
  

   and 
  therefore 
  probably 
  all 
  the 
  members 
  of 
  the 
  genus, 
  or 
  at 
  least 
  those 
  

   of 
  the 
  division 
  A^ 
  of 
  the 
  following 
  table, 
  are 
  similar 
  in 
  their 
  food 
  

   habits, 
  confining 
  their 
  attention 
  "almost 
  entirely 
  to 
  the 
  various 
  species 
  

   of 
  plants 
  of 
  the 
  botanical 
  family 
  Chenopodiaceae, 
  which 
  abound 
  in 
  the 
  

   regions 
  where 
  they 
  occur, 
  being 
  particularly 
  fond 
  of 
  the
