  One 
  female, 
  Pampaconas 
  River, 
  August. 
  

  

  I 
  have 
  determined 
  this 
  specimen 
  as 
  peruvianus 
  with 
  some 
  doubt, 
  

   the 
  type 
  being 
  of 
  the 
  opposite 
  sex 
  and 
  unavailable 
  for 
  examination 
  

   at 
  this 
  time, 
  the 
  determination 
  being 
  based 
  on 
  the 
  description 
  only, 
  

   with 
  which, 
  however, 
  this 
  female 
  agrees 
  fairly 
  well, 
  allowing 
  for 
  

   sexual 
  differences.

  Three 
  males, 
  one 
  female, 
  San 
  Miguel, 
  July 
  24, 
  6,000 
  feet 
  altitude;

  female,

  This 
  series 
  shows 
  that 
  the 
  yellow 
  color 
  of 
  certain 
  segments 
  of 
  the 
  

   antennae 
  is 
  not 
  good 
  as 
  a 
  specific 
  character. 
  The 
  specimen 
  from 
  

   Lucma, 
  which 
  is 
  just 
  like 
  the 
  San 
  Miguel 
  specimens 
  otherwise, 
  has 
  the 
  

   antennae 
  unicolorously 
  black, 
  no 
  segment 
  showing 
  any 
  yellowish. 
  

   One 
  of 
  the 
  San 
  Miguel 
  females 
  has 
  the 
  6, 
  7, 
  and 
  8 
  segments 
  enthely 
  

   yellow, 
  while 
  the 
  other 
  three 
  have 
  only 
  the 
  6 
  and 
  7 
  so 
  colored, 
  and 
  

   then 
  often 
  the 
  apical 
  part 
  of 
  one 
  or 
  both 
  of 
  these 
  segments 
  are 
  black.

  The 
  male 
  has 
  fully 
  developed 
  elytra 
  but 
  the 
  wings

  aborted, 
  

   while 
  in

  wings 
  are 
  caudate.
