  BY 
  R. 
  C. 
  L. 
  PERKINS. 
  

  

  Black, 
  or 
  brownish 
  black, 
  the 
  thorax 
  with 
  a 
  faint 
  aeneous 
  

   reflection, 
  the 
  head 
  and 
  thorax 
  also 
  faintly 
  metallic. 
  The 
  

   mandibles 
  are 
  reddish 
  and 
  the 
  scape 
  of 
  the 
  antennae 
  is 
  more 
  or 
  

   less 
  pale, 
  sometimes 
  clear 
  yellow, 
  at 
  other 
  times 
  only 
  more 
  or 
  

   less 
  obscurely 
  brown 
  in 
  dried 
  specimens. 
  The 
  tibiae 
  and 
  tarsi 
  

   are 
  yellow, 
  the 
  femora 
  dark, 
  or 
  at 
  least 
  more 
  or 
  less 
  sordid. 
  In 
  

   fresh 
  specimens 
  the 
  ocelli 
  are 
  enclosed 
  in 
  a 
  pale 
  ring, 
  and 
  the 
  

   eyes 
  pale-margined, 
  while 
  there 
  is 
  a 
  pale 
  median 
  line 
  on 
  the 
  

   face, 
  furcate 
  above 
  and 
  below, 
  forming 
  an 
  elongate 
  X-like 
  

   mark. 
  The 
  mesothoracic 
  sutures 
  are 
  mostly 
  pale, 
  as 
  also 
  the 
  

   parapsidal 
  furrows 
  and 
  the 
  scutellar 
  grooves. 
  In 
  dry 
  speci- 
  

   mens 
  generally 
  all 
  these 
  pale 
  markings 
  disappear. 
  Head 
  con- 
  

   vex 
  in 
  front 
  in 
  fresh 
  examples, 
  but 
  collapsing 
  altogether 
  in 
  dry 
  

   ones; 
  the 
  antennae 
  with 
  elongate 
  scape, 
  widening 
  to 
  the 
  apex, 
  

   and 
  about 
  as 
  long 
  as 
  the 
  pedicel 
  and 
  funicle 
  joints 
  together, 
  the 
  

   pedicel 
  obconical 
  and 
  longer 
  than 
  the 
  first 
  funicle 
  joint, 
  the 
  

   latter 
  not 
  differing 
  much 
  from 
  the 
  two 
  following, 
  and 
  trans- 
  

   versa 
  on 
  their 
  widest 
  faces, 
  the 
  club 
  ovate, 
  twice 
  as 
  long 
  as 
  its 
  

   greatest 
  width, 
  about 
  equal 
  to 
  the 
  three 
  funicle 
  joints 
  together, 
  

   and 
  with 
  a 
  spine 
  at 
  the 
  apex. 
  Thorax 
  with 
  very 
  short 
  hairs 
  

   and 
  very 
  minutely 
  punctured, 
  the 
  propodeum 
  smooth 
  and 
  

   shining 
  and 
  with 
  a 
  median 
  groove. 
  Abdomen 
  usually 
  sub- 
  

   parallel-sided 
  in 
  dry 
  specimens 
  and 
  elongate, 
  being 
  about 
  as 
  

   long 
  as 
  the 
  head 
  and 
  thorax 
  together 
  or 
  rather 
  more. 
  Length 
  

   rather 
  more 
  than 
  1mm. 
  Wings 
  evenly 
  dotted 
  with 
  short 
  hairs 
  

   and 
  with 
  short 
  marginal 
  fringe; 
  the 
  marginal 
  vein 
  with 
  two 
  

   rows 
  of 
  long 
  and 
  some 
  shorter 
  setae. 
  Male 
  quite 
  unlike 
  the 
  

   female, 
  blind 
  and 
  with 
  very 
  different 
  antennae, 
  which 
  are 
  

   9, 
  not 
  8-jointed. 
  Color, 
  yellow 
  or 
  brown, 
  sometimes 
  more 
  

   or 
  less 
  darker 
  in 
  parts, 
  the 
  apical 
  joints 
  of 
  the 
  antennae 
  more 
  

   or 
  less 
  black. 
  Scape 
  very 
  large, 
  subtriangular, 
  and 
  about 
  as 
  

   long 
  as 
  all 
  the 
  other 
  antennal 
  joints 
  together; 
  it 
  is 
  concave 
  

   beneath 
  and 
  some 
  of 
  the 
  following 
  joints 
  are 
  usually 
  with- 
  

   drawn 
  into 
  the 
  concavity, 
  which 
  is 
  partly 
  closed 
  by 
  the 
  in- 
  

   curved 
  sides, 
  pedicel 
  laminate 
  and 
  often 
  entirely 
  hidden 
  be- 
  

   neath 
  the 
  scape, 
  first 
  funicle 
  joint 
  triangular, 
  very 
  narrow 
  at 
  

   the 
  base, 
  second 
  and 
  third 
  not 
  differing 
  much 
  from 
  one 
  an- 
  

   other, 
  both 
  being 
  wide, 
  fourth 
  very 
  short 
  and 
  transverse, 
  club 
  

   three-jointed, 
  the 
  funicle 
  joints 
  are 
  set 
  with 
  longish 
  setae.
