  This 
  paper 
  consists 
  of 
  the 
  descriptions 
  of 
  ten 
  new 
  species 
  of 
  Ich- 
  

   neumonidae, 
  several 
  of 
  which 
  are 
  representatives 
  of 
  genera 
  not 
  

   previously 
  recognized 
  in 
  the 
  North 
  American 
  fauna. 
  

  

  Genus 
  NEOTYPUS 
  (Foerster) 
  Holmgren 
  

  

  No 
  North 
  American 
  representative 
  of 
  this 
  genus 
  has 
  heretofore 
  

   been 
  described. 
  The 
  following 
  new 
  species 
  is 
  typical 
  of 
  the 
  genus. 
  

  

  NEOTYPUS 
  AMERICANUS, 
  new 
  species 
  

  

  Male. 
  — 
  Length, 
  7.5 
  mm. 
  

  

  Very 
  similar 
  to 
  melanocepJialus 
  (Gmelin). 
  As 
  in 
  the 
  male 
  of 
  that 
  

   species 
  the 
  claws 
  are 
  not 
  pectinate. 
  From 
  the 
  single 
  male 
  of 
  melano- 
  

   cepJialus 
  available 
  to 
  me 
  it 
  differs 
  practically 
  only 
  as 
  follows: 
  eyes 
  

   shorter 
  than 
  width 
  of 
  vertex, 
  the 
  malar 
  space 
  and 
  ocell-ocular 
  line 
  

   therefore 
  longer, 
  the 
  former 
  nearly 
  half 
  as 
  long 
  again 
  as 
  the 
  basal 
  

   width 
  of 
  mandible 
  and 
  the 
  latter 
  about 
  twice 
  as 
  long 
  as 
  the 
  diameter 
  

   of 
  a 
  lateral 
  ocellus; 
  scutellum 
  practically 
  impunctate, 
  polished, 
  the 
  

   carinae 
  higher 
  and 
  more 
  strongly 
  converging 
  posteriorly; 
  median 
  

   areas 
  of 
  propodeum 
  narrower, 
  the 
  areola 
  fully 
  two-thirds 
  as 
  long 
  

   medially 
  as 
  wide, 
  the 
  petiolar 
  area 
  about 
  twice 
  as 
  long 
  as 
  broad, 
  

   closely 
  transversely 
  striate; 
  second 
  tergite 
  nearly 
  twice 
  as 
  wide 
  at 
  

   apex 
  as 
  at 
  base, 
  gastrocoeli 
  subquadrate, 
  broader 
  than 
  the 
  distance 
  

   between 
  them. 
  

  

  White 
  markings 
  of 
  front 
  and 
  face 
  narrower, 
  clypeus 
  only 
  faintly 
  

   pale 
  at 
  sides; 
  abdominal 
  markings 
  also 
  smaller; 
  hind 
  legs 
  entirely 
  

   black.

  A 
  female 
  from

  (C.

  apparently 
  differs 
  

   in 
  no 
  way 
  from 
  this 
  European 
  species.
