  The 
  tribe 
  Chlamydini 
  has 
  been 
  much 
  neglected 
  by 
  students 
  in 
  recent 
  

   years, 
  and 
  a 
  study 
  of 
  available 
  material 
  has 
  enabled 
  the 
  writer 
  to 
  

   attempt 
  a 
  brief 
  review 
  of 
  this 
  group. 
  

  

  Genus 
  MEGASCELIS 
  Latreille.

  This 
  neotropical 
  genus 
  belongs 
  in 
  the 
  tribe 
  Safp-ini, 
  and 
  differs 
  from 
  

   Lema 
  by 
  the 
  mouth 
  being 
  short 
  and 
  rounded 
  instead 
  of 
  being 
  pro- 
  

   longed 
  into 
  a 
  distinct 
  muzzle. 
  The 
  claws 
  are 
  connate 
  at 
  base, 
  and 
  the 
  

   sides 
  of 
  the 
  thorax 
  are 
  obtusely 
  angulate, 
  not 
  crenulate 
  or 
  spinose. 
  

   One 
  species 
  has 
  been 
  found 
  in 
  Texas 
  that 
  appears 
  to 
  beundescribed.
