  The 
  insects 
  upon 
  which 
  the 
  present 
  report 
  is 
  based 
  are 
  part 
  of 
  a 
  

   collection 
  made 
  in 
  Peru, 
  South 
  America, 
  by 
  the 
  Yale 
  expedition 
  of 
  

   1911. 
  While 
  not 
  extensive, 
  this 
  collection 
  of 
  locusts 
  is 
  interesting 
  

   on 
  account 
  of 
  the 
  large 
  percentage 
  of 
  new 
  forms 
  that 
  are 
  contained 
  

   in 
  it. 
  Onl}^ 
  19 
  species 
  and 
  subspecies 
  are 
  represented 
  by 
  the 
  92 
  speci- 
  

   mens 
  at 
  hand. 
  Of 
  these 
  7 
  are 
  apparently 
  new, 
  and 
  among 
  these 
  are 
  

   2 
  apparently 
  ^new 
  genera.

  A 
  single 
  specimen 
  was 
  taken 
  7,000 
  feet 
  above 
  sea 
  level 
  on 
  August 
  

   8, 
  at 
  Tincochaca.

  Similar 
  in 
  form 
  to 
  Cephalocoema 
  costulata 
  Burmeister, 
  but 
  very 
  

   distinct 
  from 
  that 
  species 
  in 
  its 
  much 
  smaller 
  size 
  and 
  smoother 
  body.

   this 
  insect 
  runs

  Head 
  a 
  little 
  longer 
  than 
  the 
  pronotum, 
  the 
  rostrum 
  of 
  the 
  vertex 
  

   slender, 
  quadrangular, 
  a 
  trifle 
  exceeding 
  the 
  rest 
  of 
  the 
  head 
  in 
  length, 
  

   its 
  sides 
  nearly 
  parallel, 
  in 
  the 
  male 
  gently 
  bent 
  downwards 
  apically, 
  

   in 
  the 
  female 
  straight; 
  eyes 
  not 
  prominent; 
  antennae 
  scarcely 
  one- 
  

   half 
  (male) 
  or 
  a 
  trifle 
  more 
  than 
  one-half 
  (female) 
  the 
  length 
  of 
  the 
  

   rostrum. 
  Pronotum 
  a 
  little 
  narrowed 
  in 
  advance 
  of 
  the 
  middle, 
  the 
  

   median 
  carina 
  rather 
  strong 
  and 
  bordered 
  on 
  either 
  side 
  by 
  a 
  well- 
  

   defined 
  longitudinal 
  sulcus 
  that 
  extends 
  also 
  across 
  the 
  meso- 
  and 
  

   meta-thorax 
  as 
  well 
  as 
  most 
  of 
  the 
  abdominal 
  segments. 
  There 
  are 
  

   two 
  small 
  but 
  fairly 
  conspicuous 
  wart-like 
  raised 
  spots 
  on 
  the 
  disk
