  The 
  genus 
  Adactylus 
  differs 
  from 
  Aydistis 
  and 
  the 
  allied 
  genera, 
  

   particularly 
  in 
  the 
  larval 
  stage, 
  the 
  peculiar 
  tubercular 
  processes 
  being 
  

   restricted 
  to 
  the 
  prothorax 
  and 
  9th 
  abdominal 
  segment. 
  The 
  earliest 
  

   generic 
  diagnosis 
  made 
  from 
  bennetii 
  as 
  type, 
  was 
  that 
  of 
  Curtis, 
  in 
  

   1833, 
  under 
  the 
  above 
  name, 
  but 
  he 
  stultified 
  his 
  description 
  by 
  citing 
  

   adactyla, 
  Hb. 
  (which 
  he 
  renames 
  huebneri) 
  as 
  the 
  type. 
  As, 
  however, 
  

   he 
  evidently 
  knew 
  only 
  Hubner's 
  figure 
  of 
  adactyla 
  (huebneri), 
  and 
  his 
  

   description 
  was 
  entirely 
  based 
  on 
  the 
  structure 
  of 
  bennetii, 
  we 
  have 
  no 
  

   hesitation 
  in 
  asserting 
  that 
  the 
  latter 
  is 
  the 
  true 
  type 
  of 
  the 
  genus. 
  His 
  

   diagnosis 
  reads 
  as 
  follows 
  : 
  — 
  

  

  Adactylus 
  bennetii

  seaside 
  plume).
