  THE 
  SPECIES. 
  

  

  Claws 
  of 
  fore 
  tarsus 
  two,

  Ghilianclla 
  Spinola.) 
  

  

  Inner 
  row 
  of 
  armature 
  of 
  fore 
  femur 
  consisting 
  of 
  hairs 
  or 
  bristles 
  which 
  

  

  may 
  or 
  may 
  not 
  arise 
  from 
  wart-like 
  bases 
  (fig. 
  186), 
  usually 
  a 
  

  

  single 
  spine 
  at 
  apical 
  end 
  of 
  the 
  series 
  ; 
  fore 
  femur 
  usually 
  slender. 
  

  

  enlarging 
  slightly 
  from 
  base 
  toward 
  first 
  stout 
  spine 
  (fig.

  Fore 
  femur 
  rather 
  stout, 
  first 
  strong 
  spine 
  at 
  less 
  than 
  its 
  own 
  length 
  

  

  from 
  base 
  (that 
  is 
  apex 
  of 
  trochanter) 
  ; 
  abdomen 
  racket-shaped. 
  

  

  galapagensis. 
  

  

  Fore 
  femur 
  usually 
  more 
  slender, 
  first 
  strong 
  spine 
  at 
  more 
  (usually 
  

  

  considerably 
  more) 
  than 
  its 
  own 
  length 
  from 
  base. 
  

  

  A 
  small 
  wart 
  (dark 
  in 
  mature 
  specimens) 
  at 
  middle

  dark, 
  prominent; 
  a 
  dark 
  blotch 
  

  

  or 
  spot 
  on 
  inner 
  side 
  of 
  upper 
  surface 
  of 
  fore 
  femur 
  near 
  apex.

  shorter 
  than 
  mesothorax 
  ; 
  unspined 
  portion 
  of 
  fore 
  

  

  femur 
  shorter 
  than 
  spined 
  part 
  semipallida. 
  

  

  varicornis. 
  

   bicaudata. 
  

   Metathorax 
  nearly 
  or 
  quite 
  as 
  long 
  as

  por- 
  

   tion 
  of 
  fore 
  femur 
  nearly 
  equal 
  in

  to 
  spined 
  part.

  the 
  above 
  combina- 
  

   tion 
  of 
  characters. 
  

   Mesothorax 
  not 
  longer 
  than 
  prothorax 
  ; 
  abdomen 
  not 
  bulbous. 
  

   Prothorax 
  longer 
  ; 
  spineless 
  part 
  of 
  fore 
  femur 
  shorter 
  than 
  spined 
  

  

  portion 
  alveola. 
  

  

  minimula. 
  

   succincta. 
  

   Mesothorax 
  and 
  prothorax

  equal 
  in 
  length. 
  

  

  Spineless 
  part 
  of 
  fore

  distinctly 
  shorter 
  than 
  spined 
  

   portion. 
  

  

  aliena. 
  

   pascoei. 
  

   alterata. 
  

   Spineless 
  part 
  of 
  fore 
  femur 
  nearly 
  as 
  long 
  as 
  spined 
  

   portion. 
  

  

  maculata. 
  

   personata. 
  

   Mesothorax

   Inner 
  row 
  of 
  armature 
  of 
  fore 
  femur 
  consisting 
  of 
  spines 
  (which 
  may 
  

   alternate 
  large 
  and 
  small 
  or 
  be 
  almost 
  equal 
  in 
  size) 
  and 
  between 
  

   them

   Fore

   tively
