  By 
  M. 
  A. 
  Carriker, 
  Jr. 
  

  

  Dennyus 
  Neumann, 
  a 
  genus 
  of 
  Amblycera 
  found 
  only 
  on 
  the 
  swifts 
  

   (Apodidae), 
  is 
  a 
  relatively 
  small 
  group, 
  13 
  valid 
  species 
  being 
  listed 
  by 
  

   Hopkins 
  and 
  Clay 
  in 
  "A 
  Checklist 
  of 
  the 
  Genera 
  and 
  Species 
  of 
  

   Mallophaga," 
  1952. 
  Very 
  little 
  concerning 
  the 
  genus 
  has 
  appeared 
  

   in 
  literature. 
  Apparently 
  few 
  specimens 
  have 
  been 
  collected, 
  owing, 
  

   I 
  suspect, 
  to 
  the 
  diflSculty 
  of 
  securing 
  their 
  hosts. 
  

  

  Of 
  the 
  13 
  recognized 
  species, 
  3 
  are 
  from 
  North 
  American 
  hosts, 
  2 
  

   from 
  Central 
  America, 
  1 
  from 
  South 
  America, 
  1 
  from 
  Jamaica, 
  1 
  from 
  

   Europe, 
  and 
  5 
  from 
  Asia 
  and 
  the 
  East 
  Indies. 
  

  

  Harrison 
  (Genera 
  and 
  Species 
  of 
  Mallophaga, 
  1916) 
  listed 
  six 
  valid 
  

   species, 
  of 
  which 
  one, 
  latifrons 
  Carriker 
  and 
  Shull, 
  is 
  a 
  Myrsidea. 
  

  

  Ewing 
  reviewed 
  the 
  genus 
  in 
  1930 
  (Proc. 
  U. 
  S. 
  Nat. 
  Mus., 
  vol. 
  77, 
  

   art. 
  20) 
  and 
  hsted 
  eight 
  valid 
  species, 
  of 
  which 
  two 
  are 
  Myrsidea 
  

   (Jemuralis 
  Kistiakowsky 
  and 
  piageti 
  Kistiakowsky). 
  He 
  placed 
  

   bruneri 
  Carriker 
  under 
  the 
  synonymy 
  of 
  duhius 
  Kellogg, 
  stating 
  that 
  

   Ferris 
  had 
  examined 
  a 
  cotype 
  of 
  it 
  and 
  pronounced 
  it 
  to 
  be 
  the 
  same 
  

   as 
  duhius, 
  in 
  which 
  he 
  agreed 
  ; 
  but 
  this 
  statement 
  is 
  clearly 
  an 
  error, 
  as 
  

   will 
  be 
  shown 
  later 
  in 
  this 
  paper. 
  He 
  also 
  described 
  three 
  new 
  species 
  

   (richmondi, 
  spiniger, 
  and 
  australis). 
  On 
  page 
  2 
  he 
  says, 
  "latifrons 
  

   Carriker 
  and 
  Shull 
  ... 
  is 
  a 
  true 
  Dennyus," 
  but 
  he 
  does 
  not 
  include 
  

   it 
  in 
  his 
  list 
  of 
  species 
  of 
  the 
  genus. 
  He 
  redescribed 
  and 
  figured 
  

   duhius 
  Kellogg 
  and, 
  on 
  the 
  whole, 
  left 
  a 
  much 
  clearer 
  picture 
  of 
  the 
  

   genus 
  than 
  we 
  previously 
  had.
