  of

  and 
  Ichneumonidae 
  compared 
  with 
  their 
  special 
  CEconomy 
  and 
  Instincts, 
  

   with 
  description 
  of 
  a 
  new 
  genus 
  and 
  species 
  of 
  Bee 
  Parasites,'' 
  has 
  been 
  published 
  in 
  

   the 
  Trans.

  p. 
  1. 
  The 
  chief 
  physiological 
  facts 
  comprised 
  in 
  this 
  pa- 
  

   per 
  are 
  : 
  — 
  1. 
  That 
  under 
  every 
  form 
  of 
  body, 
  and 
  of 
  each 
  individual 
  organ, 
  the 
  special 
  

   anatomy 
  of 
  a 
  species 
  is 
  an 
  index 
  to 
  its 
  natural 
  history 
  and 
  economy, 
  (a 
  fact 
  which 
  I 
  

   thought 
  John 
  Ray 
  had 
  fully 
  proved). 
  2. 
  That 
  the 
  apodal 
  parasitic 
  larvae 
  of 
  Hyme- 
  

   noptera 
  repeatedly 
  throw 
  off 
  the 
  outer 
  covering 
  of 
  their 
  bodies. 
  And 
  3. 
  That 
  the 
  

   digestive 
  apparatus 
  of 
  these 
  larvae 
  is 
  at 
  first 
  a 
  simple 
  bag, 
  rounded 
  and 
  closed 
  at 
  its 
  

   larger 
  extremity, 
  with 
  an 
  imperforated 
  intestine 
  proceeding 
  from 
  it, 
  without 
  an 
  anal 
  

   outlet 
  ; 
  but 
  that 
  as 
  the 
  larva 
  approach 
  maturity, 
  the 
  digestive 
  apparatus 
  becomes 
  

   elongated, 
  the 
  coecal 
  extremity 
  of 
  the 
  sac 
  becomes 
  perforated, 
  the 
  cells 
  separating 
  in 
  

   the 
  axis 
  of 
  the 
  column 
  to 
  form 
  a 
  tube, 
  an 
  anal 
  outlet 
  being 
  also 
  formed. 
  The 
  species 
  

   described 
  in 
  illustration 
  of 
  these 
  facts 
  are 
  two 
  Chalcidideous 
  insects 
  ; 
  1, 
  termed 
  by 
  Mr. 
  

   Newport 
  Anihophorabia 
  retusa,t 
  and 
  2, 
  Monodontomerus 
  nitidus, 
  and 
  one 
  Ichneu- 
  

   monideous 
  species, 
  Paniscus 
  virgatus.
