  merely 
  in 
  terms 
  of 
  the 
  abdominal 
  appendages 
  of 
  the 
  male; 
  it 
  is, 
  there- 
  

   fore, 
  not 
  equivalent 
  to 
  Paroxya 
  as 
  I 
  formerly 
  detined 
  it 
  and 
  as 
  I 
  here 
  

   still 
  more 
  closely 
  distinguish 
  it 
  from 
  the 
  other 
  genera. 
  

  

  14. 
  BORCKII 
  SERIES. 
  

  

  A 
  homogeneous 
  group 
  in 
  which 
  the 
  prozona 
  of 
  the 
  male 
  is 
  distinctly 
  

   longitudinal 
  and 
  from 
  a 
  third 
  to 
  a 
  half 
  longer 
  than 
  the 
  metazona, 
  the 
  

   posterior 
  margin 
  of 
  the 
  pronotum 
  being 
  subtruucate. 
  The 
  interspace 
  

   between 
  the 
  mesosternal 
  lobes 
  in 
  the 
  same 
  sex 
  varies 
  from 
  a 
  little 
  longer 
  

   than 
  broad 
  to 
  twice 
  as 
  long 
  as 
  broad. 
  The 
  antennae 
  vary 
  considerably 
  

   in 
  length, 
  but 
  generally 
  differ 
  but 
  little 
  between 
  the 
  two 
  sexes. 
  There 
  

   is 
  also 
  little 
  diversity 
  between 
  the 
  sexes 
  in 
  the 
  prominence 
  of 
  the 
  eyes. 
  

   The 
  hind 
  tibiae 
  are 
  dark 
  blue, 
  sometimes 
  purplish, 
  and 
  have 
  nine 
  to 
  

   twelve 
  spines 
  in 
  the 
  outer 
  series. 
  

  

  The 
  supraanal 
  plate 
  is 
  triangular 
  with 
  acutangulate 
  or 
  rectangulate 
  

   apex; 
  the 
  furcula 
  is 
  reduced 
  to 
  mere 
  projecting 
  points; 
  the 
  cerci 
  are 
  

   broad 
  and 
  swollen 
  at 
  the 
  base, 
  taper 
  rapidly, 
  and 
  terminate 
  in 
  a 
  slen- 
  

   der, 
  produced, 
  more 
  or 
  less 
  curling 
  finger; 
  the 
  supraanal 
  plate 
  is 
  either 
  

   very 
  narrow 
  as 
  compared 
  to 
  its 
  length 
  and 
  then 
  deeply 
  hollowed 
  apic- 
  

   ally, 
  with 
  a 
  strongly 
  sinuate 
  lateral 
  margin, 
  or 
  it 
  is 
  only 
  a 
  little 
  longer 
  

   than 
  broad 
  with 
  a 
  nearly 
  straight 
  margin, 
  the 
  apical 
  margin 
  always 
  

   entire. 
  

  

  There 
  are 
  six 
  species, 
  ranging 
  from 
  rather 
  small 
  to 
  a 
  little 
  above 
  the 
  

   medium 
  size, 
  and 
  they 
  are 
  mainly 
  confined 
  to 
  the 
  Pacific 
  coast 
  from 
  

   Washington 
  to 
  California. 
  But 
  one 
  of 
  the 
  species 
  occurs 
  also 
  as 
  far 
  

   inland 
  as 
  Idaho 
  and 
  Wyoming, 
  and 
  another 
  is 
  known 
  from 
  San 
  Luis 
  

   Potosi, 
  Mexico.
