  The 
  two 
  clypeal 
  spots 
  are 
  also 
  found 
  in 
  A. 
  aztecum 
  Cresson, 
  but 
  the 
  

   markings 
  of 
  head 
  and 
  abdomen 
  are 
  different.

  about 
  7 
  mm. 
  ; 
  black 
  without 
  light 
  markings 
  on 
  head 
  

   and 
  thorax, 
  or 
  there 
  may 
  be 
  two 
  hardly 
  noticeable 
  dots 
  on 
  front 
  

   margin 
  of 
  mesonotum, 
  and 
  a 
  narrow 
  line 
  on 
  scutellum; 
  antennae 
  

   black; 
  conspicuous 
  white 
  hair 
  at 
  sides 
  of 
  face; 
  mesonotum 
  and 
  scutel- 
  

   lum 
  glistening 
  between

  I 
  had 
  at 
  first 
  referred 
  this 
  to 
  Dianthidium, 
  where 
  it 
  falls 
  nearest 
  to 
  

   D. 
  agnatum 
  Cresson, 
  from 
  Mexico. 
  As 
  in 
  Dianthidium, 
  the 
  feet 
  have 
  

   pulvHli, 
  and 
  the 
  second 
  recurrent 
  nervure 
  goes 
  beyond 
  the 
  second 
  

   submarginal 
  cell. 
  The 
  posterior 
  coxae 
  are 
  not 
  spined. 
  It 
  is 
  some- 
  

   what 
  related 
  to 
  S. 
  shattucki 
  Cockerell 
  from 
  Yucatan, 
  but 
  the 
  yellow 
  

   marking 
  is 
  quite 
  different. 
  It 
  can 
  hardly 
  be 
  doubted 
  that 
  Stelis, 
  as 
  

   usually 
  understood, 
  is 
  polyphyletic, 
  and 
  the 
  present 
  species 
  may 
  

   represent 
  a 
  group 
  derived 
  from 
  Dianthidium 
  or 
  a 
  related 
  form.

  HEEIADES 
  RUFAPICATUS. 
  new 
  species 
  

  

  Female. 
  — 
  Length 
  about 
  6 
  mm., 
  with 
  the 
  apical 
  part 
  of 
  the 
  abdomen 
  

   covered 
  with 
  red 
  hair. 
  I 
  felt 
  sure 
  that 
  this 
  was 
  H. 
  rufocaudatus 
  

   Friese, 
  but 
  that 
  has 
  tergites 
  4 
  to 
  6 
  "uberall 
  gelbraun 
  behaart," 
  whereas 
  

   in 
  our 
  species 
  this 
  is 
  true 
  of 
  tergites 
  5 
  and 
  6 
  but 
  not 
  at 
  all 
  of 
  4, 
  which 
  

   is 
  just 
  like 
  3, 
  bare 
  and 
  shinmg, 
  with 
  a 
  pale 
  reddish 
  apical 
  band; 
  the 
  

   second 
  tergite 
  is 
  similarly 
  shining, 
  with 
  the 
  apical 
  band 
  interrupted, 
  

   and 
  the 
  first 
  has 
  a 
  linear 
  whitish 
  apical 
  band, 
  enlarged 
  to 
  a 
  large 
  

   patch 
  on 
  each 
  side; 
  facial 
  quadrangle 
  longer 
  than 
  wide, 
  with 
  white 
  

   hairs 
  at 
  sides; 
  clypeus 
  dull, 
  supraclypeal 
  area 
  shining; 
  tegulae 
  black, 
  

   wings 
  slightly 
  dusky 
  ; 
  hair 
  of 
  thorax 
  white 
  and 
  very 
  scanty; 
  mesonotum 
  

   feebly 
  shining; 
  base 
  of 
  metathorax 
  pohshed; 
  ventral 
  scopa 
  rather 
  

   poorly 
  developed. 
  

  

  Male. 
  — 
  5 
  mm. 
  long; 
  antennae 
  long, 
  reaching 
  base 
  of 
  metathorax; 
  

   face 
  and 
  front 
  densely 
  covered 
  with 
  white 
  hairs.
