  ; 
  ungues 
  diverging, 
  

   armed

  Found 
  at 
  Vallecitas, 
  San 
  Diego 
  Co., 
  California 
  in 
  April, 
  on 
  flowers 
  of 
  a 
  composite 
  

  

  plant. 
  I 
  can 
  find 
  no 
  sexual 
  characters 
  in 
  the 
  specimens 
  collected. 
  By 
  examination 
  

  

  I 
  find 
  the 
  abdominal 
  stigmata 
  situated 
  in 
  the 
  dorsal 
  inflexed 
  portion 
  of 
  the 
  ventral 
  

  

  segments 
  ; 
  the 
  last 
  pair 
  I 
  cannot 
  detect, 
  since 
  the 
  margins 
  of 
  the 
  ventral 
  segments 
  are 
  

  

  thin 
  and 
  retlexed 
  above 
  the 
  dorsal 
  surface, 
  so 
  as 
  to 
  produce 
  a 
  concave 
  surface, 
  in 
  which 
  

  

  the 
  posterior 
  pairs 
  are 
  concealed.

  This 
  division 
  is 
  known 
  among 
  those 
  having 
  prominent 
  conical 
  anterior 
  coxse 
  by 
  

   the 
  ventral 
  segments 
  being 
  connate, 
  the 
  sixth 
  indistinct 
  or 
  even 
  invisible 
  ; 
  by 
  the 
  

   large 
  parapleurse 
  ; 
  the 
  tibia? 
  without 
  terminal 
  spurs 
  or 
  at 
  most 
  with 
  a 
  single 
  very 
  small 
  

   one, 
  and 
  by 
  the 
  ungues 
  being 
  chelate 
  (i. 
  e. 
  capable 
  of 
  being 
  folded 
  against 
  the 
  last 
  

   joint 
  of 
  the 
  tarsi,) 
  not 
  divergent, 
  unequal 
  and 
  without 
  any 
  onychium. 
  

  

  In 
  this 
  division, 
  though 
  not 
  in 
  any 
  American 
  form, 
  is 
  found 
  a 
  modification 
  of 
  ligula 
  

   not 
  seen 
  or 
  only 
  exceptionally 
  in 
  any 
  of 
  the 
  preceding 
  tribes 
  : 
  the 
  ligula 
  is 
  membra- 
  

   nous, 
  and 
  not 
  connate 
  with 
  the 
  mentum 
  : 
  by 
  this 
  character, 
  found 
  in 
  Pachycnemis 
  

   and 
  allied 
  genera, 
  the 
  passage 
  to 
  the 
  following 
  group 
  is 
  most 
  naturally 
  made. 
  

  

  The 
  only 
  genus 
  found 
  in 
  our 
  country, 
  and 
  in 
  fact 
  the 
  only 
  one 
  found 
  outside 
  of 
  

   Southern 
  Africa,

  ; 
  the 
  anterior 
  tibias, 
  as 
  in 
  the 
  others 
  of

   two

  which 
  is

  The 
  antenna? 
  

   as 
  in 
  the 
  other 
  species 
  are 
  9-jointed. 
  The 
  scales 
  of
