  Segment 
  VIII. 
  The 
  male 
  genitalia 
  is 
  also 
  quite 
  different 
  from 
  all 
  

   others 
  of 
  the 
  genus 
  which 
  I 
  have 
  seen, 
  the 
  remainder 
  being 
  unusually 
  

   uniform. 
  I 
  have 
  carefullj^ 
  examined 
  Uchida's 
  description 
  and 
  figures 
  

   and 
  am 
  of 
  the 
  opinion 
  that 
  this 
  species 
  may 
  be 
  entitled 
  to 
  subgeneric 
  

   rank, 
  but 
  without 
  actual 
  examination 
  of 
  specimens 
  I 
  hesitate 
  to 
  

   do 
  this.

  Like 
  most 
  of 
  Kellogg's 
  descriptions, 
  this 
  one 
  is 
  very 
  inadequate 
  and 
  

   the 
  figure 
  not 
  particularly 
  illuminating. 
  The 
  species 
  seems 
  to 
  be 
  

   characterized 
  by 
  its 
  small 
  size, 
  circular 
  frontal 
  margin 
  of 
  head, 
  and 
  

   small, 
  rounded 
  temples.

  Type.

  Female 
  adult 
  from 
  Chaetura

  (Jardine), 
  collected 
  

   by 
  the 
  author 
  at

  B.

  (in 
  

   collection

  I 
  have 
  been 
  undecided 
  as 
  to 
  the 
  generic 
  position 
  of 
  this 
  species, 
  

   whether 
  it 
  belongs 
  in 
  Eureum 
  or 
  Dennyus. 
  Certainly 
  it 
  presents 
  

   characters 
  common 
  to 
  both, 
  resembling 
  the 
  former 
  genus 
  in 
  its 
  wide, 
  

   short 
  head, 
  rectangular 
  prothorax, 
  and 
  oval 
  abdomen. 
  It 
  might 
  be 
  

   classed 
  as 
  the 
  connecting 
  link 
  between 
  Dennyus 
  and 
  Eureum, 
  but 
  on 
  

   the 
  whole 
  it 
  seems 
  best 
  to 
  place 
  it 
  under 
  Dennyus. 
  

  

  Diagnosis. 
  — 
  The 
  species 
  is 
  so 
  different 
  from 
  all 
  other 
  known 
  species 
  

   of 
  the 
  genus 
  that, 
  in 
  addition 
  to 
  the 
  figure 
  given, 
  very 
  little 
  description 
  

   seems 
  necessary. 
  

  

  The 
  head 
  is 
  nearly 
  twice 
  as 
  wide 
  as 
  long, 
  with 
  pre-antennary 
  area 
  

   flatly 
  conical, 
  and 
  sides 
  flatly 
  convex; 
  temples 
  short 
  and 
  expanded 
  

   laterally; 
  prothorax 
  quadrilateral 
  in 
  shape, 
  encircled 
  by 
  a 
  wide, 
  deeply 
  

   chitinized 
  band, 
  with 
  three 
  spines 
  on 
  anterior 
  angles, 
  two 
  long 
  hairs 
  

   on 
  the 
  rounded 
  posterior 
  angles 
  and 
  two 
  on 
  posterior 
  margin. 
  The 
  

   prosternum 
  is 
  of 
  the 
  usual 
  type 
  for 
  the 
  genus, 
  with 
  four 
  short 
  spines 
  

   and 
  two 
  longer, 
  thickened 
  setae, 
  all 
  set 
  in 
  the 
  marginal 
  band.
