  Genus 
  ANISOBAS 
  Wesroael 
  

  

  No 
  American 
  representative 
  of 
  this 
  genus 
  has 
  heretofore 
  been 
  de- 
  

   scribed. 
  The 
  first 
  of 
  the 
  following 
  two 
  new 
  species 
  is 
  typical 
  of 
  the 
  

   genus, 
  being 
  very 
  closely 
  allied 
  to 
  the 
  genotype, 
  Anisobas 
  cingula- 
  

   torius 
  (Gravenhorst) 
  . 
  The 
  second 
  species 
  is 
  somewhat 
  anomalous. 
  

  

  ANISOBAS 
  NEARCTICUS, 
  new 
  species 
  

  

  Female. 
  — 
  Length, 
  7.5 
  mm. 
  

  

  Differs 
  from 
  cingulatorius 
  principally 
  as 
  follows: 
  vertex 
  arched 
  

   above 
  level 
  of 
  top 
  of 
  eyes; 
  eyes 
  as 
  long 
  as 
  width 
  of 
  vertex 
  (not 
  longer 
  

   as 
  in 
  cingulatorius), 
  parallel 
  within; 
  malar 
  space 
  distinctly 
  shorter 
  

   than 
  basal 
  width 
  of 
  mandible; 
  clypeal 
  furrow 
  represented 
  by 
  a 
  broad, 
  

   shallow 
  impression; 
  clypeus 
  convex, 
  the 
  apex 
  slightly 
  concavely 
  trun- 
  

   cate; 
  flagellum 
  with 
  25 
  joints 
  (31 
  in 
  cingulatorius); 
  propodeum 
  

   apically 
  and 
  laterally 
  more 
  strongly 
  rugose; 
  areola 
  constricted 
  

   medially 
  and 
  there 
  divided 
  by 
  two 
  strong 
  parallel 
  rugae 
  ; 
  apical 
  carina 
  

   very 
  high 
  at 
  apex 
  of 
  middle 
  lateral 
  area 
  (area 
  dentipara) 
  ; 
  dorsal 
  

   carinae 
  of 
  first 
  tergite 
  strong 
  and 
  extending 
  well 
  on 
  to 
  postpetiole, 
  

   the 
  latter 
  with 
  a 
  median 
  impression; 
  second 
  tergite 
  barely 
  half 
  as 
  

   broad 
  at 
  base 
  as 
  at 
  apex; 
  third 
  tergite 
  more 
  than 
  twice 
  as 
  wide 
  at 
  

   base 
  as 
  long. 
  

  

  Frontal 
  white 
  markings 
  extending 
  broadly 
  on 
  to 
  face; 
  scutellar 
  

   white 
  spot 
  smaller; 
  hind 
  tibia 
  red, 
  broadly 
  fuscous 
  at 
  apex; 
  otherwise 
  

   colored 
  as 
  cingulatorius.

  ANISOBAS 
  BICOLOR, 
  new 
  species 
  

  

  Differs 
  from 
  both 
  cingulatorius 
  (Gravenhorst) 
  and 
  nearcticus 
  Cush- 
  

   man 
  in 
  its 
  entirely 
  black 
  thorax 
  and 
  entirely 
  red 
  abdomen. 
  Appar- 
  

   ently 
  not 
  very 
  closely 
  related 
  to 
  any 
  of 
  the 
  other 
  European 
  species. 
  

  

  Female. 
  — 
  Length, 
  9 
  mm.;

  mm. 
  

  

  Head
