  This 
  insect 
  will 
  be 
  easily 
  identified, 
  not 
  only 
  by 
  the 
  slender 
  facies, 
  

   the 
  nearly 
  truncate 
  clypeus, 
  and 
  the 
  long, 
  slender 
  legs, 
  but 
  also 
  by 
  

   the 
  shape 
  of 
  the 
  claws 
  of 
  the 
  intermediate 
  legs 
  which 
  are 
  armed 
  

   underneath 
  with 
  a 
  conspicuous 
  tooth, 
  like 
  some 
  other 
  species, 
  but 
  are 
  

   double 
  instead 
  of 
  being 
  simple.

  are 
  covered 
  with 
  minute, 
  nearly 
  contiguous 
  

   flavescent 
  scales 
  leaving 
  a 
  narrow 
  longitudinal 
  band 
  on

   the 
  deep 
  median 
  groove 
  partly 
  denuded,

  also 
  a 
  similar

   shorter

   one 
  reaches 
  only 
  to 
  about 
  the 
  median 
  part,

  scales 
  are 
  whiter 
  

   than 
  those 
  on 
  the 
  prothorax 
  and 
  larger,

  the 
  outer 
  angles 
  of 
  which 
  are 
  rounded 
  ;
