  STATES.

  1. 
  MACROPHYLL^E. 
  

  

  A 
  group 
  having 
  the 
  epimera 
  and 
  parapleural 
  of 
  the 
  metathorax 
  broad 
  as 
  in 
  Melo- 
  

   lonthje, 
  but 
  differing 
  by 
  the 
  ventral 
  segments 
  not 
  being 
  connate, 
  although 
  the 
  sixth 
  

   is 
  less 
  closely 
  articulated. 
  Besides 
  this 
  character, 
  the 
  long 
  slender 
  tarsi, 
  and 
  the 
  

   very 
  long 
  hair 
  of 
  the 
  head, 
  thorax 
  and 
  sides, 
  enable 
  them 
  to 
  be 
  readily 
  recognized. 
  

   The 
  group 
  has 
  heretofore 
  had 
  no 
  representative 
  on 
  the 
  American 
  continent, 
  but 
  I 
  am 
  

   now 
  enabled 
  to 
  make 
  known 
  a 
  new 
  genus 
  found 
  within 
  our 
  territories. 
  

  

  Characters 
  derived 
  from 
  the 
  abdomen, 
  and 
  not 
  mentioned 
  by 
  Burmeister 
  or 
  Lacor- 
  

   daire 
  are 
  the 
  very 
  distinct 
  and 
  straight 
  fissure-like 
  suture 
  between 
  the 
  fifth 
  ventral 
  

   segment 
  and 
  the 
  propygidium; 
  the 
  stigma 
  is 
  situated 
  on 
  the 
  ventral 
  segment, 
  near 
  

   the 
  anterior 
  margin, 
  but 
  remote 
  from 
  the 
  suture 
  just 
  mentioned. 
  

  

  The 
  group 
  in 
  its 
  present 
  form 
  was 
  established 
  by 
  Lacordaire. 
  It 
  consists 
  of 
  the 
  

   group 
  Tanyproctini 
  of 
  Erichson, 
  less 
  the 
  genus 
  Tanyproctus. 
  

  

  Burmeister 
  combines 
  with 
  it 
  Erichson 
  and 
  Lacordaire's 
  group 
  Pachypodii, 
  which 
  

   differ 
  not 
  only 
  by 
  the 
  variable 
  characters 
  derived 
  from 
  the 
  less 
  development 
  of 
  the 
  

   oral 
  organs, 
  but 
  by 
  the 
  epimera 
  of 
  the 
  metathorax 
  being 
  narrow.

  Seems 
  to 
  be 
  allied 
  to 
  Tryssus 
  Er. 
  and 
  Trichiodera 
  Burm., 
  but 
  the 
  latter 
  has 
  10- 
  

   jointed 
  antennae 
  ; 
  the 
  former 
  has, 
  it 
  is 
  true, 
  9-jointed 
  antenna?, 
  but 
  is 
  very 
  insuf- 
  

   ficiently 
  described, 
  and 
  being 
  from 
  southern 
  Africa 
  can 
  hardly 
  be 
  the 
  same 
  as 
  the 
  

   present 
  genus.
