  straight, 
  and 
  having 
  an 
  inner 
  spur 
  ; 
  anterior 
  claws 
  double 
  ; 
  the 
  inner 
  

   one 
  is 
  not 
  deeply 
  cleft 
  at 
  about 
  the 
  median 
  part, 
  and 
  the 
  outer 
  is 
  

   more 
  slender, 
  half 
  the 
  length 
  of 
  the 
  inner, 
  and 
  cleft 
  at 
  the 
  tip 
  ; 
  the 
  

   outer 
  claw 
  of 
  the 
  intermediate 
  legs 
  is 
  similar 
  to 
  the 
  inner 
  one 
  of 
  the 
  

   anterior 
  legs, 
  and 
  the 
  inner 
  is 
  slender 
  and 
  bifid 
  at 
  tip, 
  in 
  the 
  

   hind 
  legs 
  the 
  outer 
  claw 
  is 
  very 
  robust 
  and 
  single 
  {Peritrichia), 
  or 
  

   there 
  is 
  a 
  thin 
  and 
  simple 
  inner 
  one 
  half 
  the 
  length 
  of 
  the 
  outer 
  and 
  

   set 
  against 
  it 
  (Pherocoma) 
  . 
  

  

  The 
  facies 
  of 
  the 
  insects 
  included 
  in 
  this 
  genus 
  varies 
  a 
  little. 
  

   Peritrichia 
  tristis 
  resembles 
  Anisonyx, 
  while 
  the 
  facies 
  of 
  P. 
  capicola 
  

   approximates 
  to 
  that 
  of 
  Lepitrix. 
  The 
  species 
  of 
  Pherocoma 
  are 
  

   more 
  parallel 
  than 
  the 
  true 
  Peritrichia, 
  the 
  clypeus 
  is 
  less 
  elongate 
  

   and 
  less 
  narrowed, 
  and 
  in 
  the 
  hind 
  tarsi 
  the 
  inner 
  claw 
  is 
  simple 
  

   and 
  there 
  is 
  a 
  small 
  outer 
  one 
  pressed 
  against 
  the 
  inner, 
  while 
  in 
  

   Peritrichia 
  this 
  claw 
  is 
  simple 
  and 
  single 
  ; 
  there 
  are, 
  however, 
  

   numerous 
  variations 
  between 
  these 
  two 
  forms 
  ; 
  for 
  instance, 
  P. 
  hirtipcs 
  

   is 
  a 
  Pherocoma 
  because 
  of 
  the 
  double 
  claw 
  of 
  the 
  hind 
  tarsi, 
  and 
  a 
  

   true 
  Peritrichia 
  because 
  of 
  the 
  acuminate 
  clypeus 
  and 
  of 
  the 
  elytra 
  

   being 
  attenuate 
  behind.
