  Specimens 
  of 
  the 
  species 
  coming 
  from 
  an 
  elevation 
  of 
  about 
  4,000 
  

   feet 
  are 
  in 
  the 
  writer's 
  collection. 
  These 
  latter 
  are 
  typical 
  as 
  to 
  size, 
  

   but 
  some 
  have 
  fully 
  developed 
  wings 
  that 
  extend 
  beyond 
  the 
  apex 
  

   of 
  the 
  abdomen 
  and 
  tips 
  of 
  the 
  hind 
  femora 
  in 
  the 
  male.

  DICHROPLUS, 
  species. 
  

  

  The 
  collection 
  also 
  contains 
  two 
  mutilated 
  females 
  of 
  a 
  Dichroplus 
  

   that 
  were 
  collected 
  on 
  the 
  Pampaconas 
  River 
  during 
  the 
  month 
  of 
  

   August. 
  These 
  may 
  belong 
  to 
  D. 
  peruvianus 
  also, 
  in 
  which 
  case 
  the 
  

   species 
  under 
  consideration 
  shows 
  a 
  still 
  wider 
  variation 
  than 
  is 
  

   usual 
  in 
  the 
  majority 
  of 
  species 
  forming 
  the 
  genus. 
  One 
  feature 
  of 
  

   these 
  last 
  specimens 
  is 
  the 
  coarseness 
  and 
  paucity 
  of 
  the 
  veins 
  of 
  the 
  

   elytra. 
  

  

  PARADICHROPLUS 
  ANDEANUS, 
  new 
  species. 
  

  

  A 
  medium 
  sized, 
  variable 
  insect 
  with 
  distinctly 
  fuscous 
  banded 
  

   hind 
  femora 
  and 
  red-tinted 
  tibias. 
  Pronotum 
  expanding 
  strongly 
  

   posteriorly; 
  the 
  dorsum 
  of 
  the 
  abdomen 
  linearly 
  longitudinally 
  pallid 
  

   at 
  middle 
  and 
  with 
  a 
  row 
  of 
  fuscous 
  dots 
  on 
  each 
  side 
  near 
  the 
  middle 
  

   of 
  each 
  segment. 
  Antennae 
  rather 
  robust, 
  short, 
  and 
  gently 
  flattened. 
  

   Inner 
  face 
  and 
  lower 
  sulcus 
  of 
  the 
  hind 
  femora 
  bright 
  reddish 
  orange 
  

   in 
  color. 
  Possibly 
  somewhat 
  related 
  to 
  P. 
  hilolus 
  Giglio-Tos, 
  which 
  

   insect 
  has 
  not 
  been 
  examined 
  by 
  the 
  writer. 
  

  

  Surface 
  of 
  the 
  body 
  rather 
  smooth 
  and 
  appearing 
  polished 
  or 
  gla- 
  

   brous. 
  Head 
  of 
  moderate 
  size, 
  a 
  little 
  wider 
  than 
  (male) 
  or

   as 
  wide 
  (female) 
  as 
  the 
  anterior 
  edge 
  of 
  the 
  pronotum 
  ; 
  vertex 
  a 
  little 
  

   narrower 
  than 
  the 
  prominent 
  frontal 
  costa 
  at 
  the 
  ocellus, 
  its 
  bounding 
  

   walls 
  prominent, 
  the 
  sulcus 
  fairly 
  profound; 
  frontal 
  costa 
  provided 
  

   with 
  several 
  coarse 
  punctures 
  above, 
  most 
  noticeably 
  sulcate 
  in 
  the 
  

   vicihity 
  of 
  the 
  ocellus, 
  continued 
  to 
  the 
  base 
  of 
  the 
  clypeus. 
  Eyes 
  

   large 
  and 
  fairly 
  prominent 
  in 
  the 
  male, 
  not 
  much 
  longer 
  than 
  wide, 
  

   their 
  anterior 
  edge 
  but 
  little 
  arcuate, 
  in 
  the 
  female 
  less 
  prominent 
  and 
  

   with 
  the 
  anterior 
  margin 
  straight; 
  cheeks 
  below 
  the 
  eyes 
  in 
  the
