   middle, 
  markedly 
  dilated 
  at

  and 
  the

  outline 
  rather 
  strongly 
  curved 
  ; 
  

   fairly 
  closely 
  set 
  with 
  non-contiguous 
  scales, 
  and 
  with 
  a 
  short 
  median 
  furrow 
  between

  narrowed 
  but 
  not 
  constricted 
  in

   subtruncate 
  and

  rather 
  coarsely

   more

  almost 
  flat. 
  Elytra 
  very 
  narrowly 
  

   ovate,

  Lachnopus 
  coffeae 
  montanus, 
  subsp. 
  nov. 
  

  

  This 
  upland 
  race 
  differs 
  from 
  the 
  typical 
  coast 
  form 
  in 
  being 
  somewhat 
  larger 
  

   and 
  having 
  the 
  legs 
  markedly 
  paler 
  ; 
  the 
  scales 
  on 
  the 
  upper 
  surface 
  are 
  much 
  sparser

  view 
  of 
  median 
  lobe 
  ;

  view 
  of

  and 
  more 
  evenly 
  distributed, 
  and 
  they 
  are 
  also 
  rather 
  smaller 
  and 
  more 
  nearly 
  

   circular 
  ; 
  most 
  of 
  them 
  being 
  very 
  pale 
  blue 
  or 
  bluish 
  white 
  ; 
  on 
  the 
  other 
  hand 
  the 
  

   stripe 
  of 
  white 
  scaling 
  along 
  the 
  side 
  of 
  the 
  sternum 
  is 
  much 
  denser 
  and 
  more 
  sharply 
  

   defined. 
  There 
  appears, 
  however, 
  to 
  be 
  no 
  reliable 
  structural 
  difference 
  either 
  in 
  

   the 
  external 
  characters 
  or 
  in 
  the 
  male 
  genitalia.

  Described 
  from 
  two 
  males. 
  

  

  The 
  adults 
  of 
  both 
  forms 
  are 
  recorded 
  as 
  feeding 
  on 
  the 
  young 
  leaves 
  of 
  coffee. 
  

  

  The 
  form 
  of 
  the 
  male 
  aedoeagus 
  is 
  shown 
  in 
  fig. 
  1 
  ; 
  the 
  uneverted 
  sac 
  is 
  contained 
  

   entirely 
  within 
  the 
  median 
  lobe 
  and 
  is 
  covered 
  with 
  asperities 
  for 
  about 
  one-third
