  A 
  

   secondary

  was 
  reared

   It

  here

  In 
  1895

  1896, 
  Fletcher 
  was 
  successful 
  in 
  

   crossing 
  British 
  A. 
  filipendulae 
  with 
  Italian 
  A. 
  ochsenheimeri, 
  and 
  also 
  

   obtained 
  the 
  reciprocal 
  cross.

  Fletcher 
  records 
  further 
  

   (Trans. 
  Ent.

  that

  2Egeriides. 
  — 
  Concerning 
  hybridism 
  among 
  the 
  iEgeriids, 
  some 
  

   interesting 
  details 
  as 
  to 
  a 
  supposed 
  hybridisation 
  in 
  nature 
  of 
  JEgeria 
  

   chrysidiformis 
  and 
  JE. 
  ichneumoniformis 
  are 
  given 
  (Ent. 
  Rec, 
  xiii., 
  pp. 
  

   171-175) 
  by 
  Delahaye, 
  who 
  asserts 
  that 
  he 
  observed 
  pairing 
  between 
  

   ichneumoniformis 
  $ 
  and 
  megillaeformis 
  ? 
  , 
  and 
  between 
  chrysidiformis 
  

   $ 
  and 
  megillaeformis 
  ? 
  , 
  but 
  the 
  facts 
  given 
  are 
  such 
  as 
  to 
  obscure 
  

   any 
  useful 
  conclusions.

  Among 
  the

  Standfuss 
  reports 
  (Handbuch,

  that 
  Plingeler 
  reared 
  hybrid
