  ON 
  A 
  NEW 
  SPECIES 
  OF 
  HYPOCALA. 
  

  

  Among 
  the 
  unequaled 
  collections 
  in 
  number, 
  variety 
  and 
  

   rarity, 
  made 
  at 
  the 
  famous 
  Center 
  locality 
  during 
  the 
  season 
  

   of 
  1877, 
  perhaps 
  the 
  most 
  interesting 
  capture 
  is 
  that 
  which 
  

   gives 
  us, 
  for 
  the 
  first 
  time, 
  representation 
  of 
  a 
  genus 
  of 
  trop- 
  

   ical 
  insects 
  of 
  marked 
  beauty, 
  rivalling 
  the 
  Catocalas, 
  to 
  

   which 
  they 
  are 
  closely 
  allied. 
  

  

  Of 
  the 
  eight 
  species 
  of 
  Hypocala 
  described 
  by 
  Guenee 
  (two 
  

   of 
  which 
  are 
  Fabrician 
  species), 
  five 
  are 
  from 
  the 
  East 
  Indies, 
  

   one 
  from 
  Africa, 
  one 
  from 
  Honduras 
  (N". 
  Lat. 
  15°) 
  and 
  one 
  

   from 
  Hayti 
  (N. 
  Lat. 
  19°). 
  That 
  a 
  species, 
  typical 
  of 
  the 
  genus, 
  

   should 
  occur 
  in 
  the 
  State 
  of 
  New 
  York 
  (N. 
  Lat. 
  42°), 
  is 
  a 
  dis- 
  

   covery 
  of 
  exceeding 
  interest, 
  adding, 
  as 
  it 
  does, 
  to 
  our 
  list 
  of 
  

   Noctuas, 
  a 
  peculiar 
  and 
  beautiful 
  form, 
  which, 
  there 
  is 
  reason 
  

   to 
  believe, 
  will 
  long 
  remain 
  a 
  rarity 
  in 
  our 
  collections. 
  

  

  In 
  consideration 
  of 
  the 
  peculiar 
  characters 
  of 
  these 
  moths, 
  

   Guenee, 
  in 
  his 
  JSToctuelites, 
  Tome 
  III, 
  has 
  arranged 
  them 
  in 
  a 
  

   separate 
  family 
  which 
  he 
  designates 
  as 
  Hypocalidse, 
  consist- 
  

   ing 
  of 
  the 
  single 
  genus 
  of 
  Hypocala. 
  The 
  genus 
  he 
  defines 
  

   as 
  follows: 
  

  

  " 
  Caterpillars 
  unknown. 
  Moths 
  — 
  Antennae, 
  medium, 
  more 
  

   or 
  less 
  pubescent 
  in 
  the 
  £ 
  . 
  Palpi 
  very 
  projecting, 
  quite 
  large, 
  

   compressed, 
  contiguous, 
  with 
  joints 
  indistinct 
  and 
  ordinarily 
  

   of 
  triangular 
  form 
  — 
  the 
  last 
  as 
  scaly 
  as 
  the 
  preceding. 
  Tongue 
  

   moderate. 
  Eyes 
  ]arge 
  and 
  projecting. 
  Frontal 
  tuft 
  elongated,

  thick 
  and 
  close 
  (serre). 
  Thorax 
  oblong, 
  scaly, 
  stout. 
  

   Abdomen 
  long, 
  swollen, 
  not 
  carinated 
  above, 
  somewhat 
  hairy, 
  

   yellow 
  with 
  black 
  spots, 
  bearing 
  a 
  small 
  tuft 
  at 
  the 
  base. 
  Legs 
  

   strong, 
  slightly 
  hairy. 
  Wings 
  subdentate 
  ; 
  the 
  superiors 
  pul- 
  

   verulent, 
  the 
  subterminal 
  line 
  in 
  part 
  distinct 
  : 
  the 
  inferiors 
  

   yellow 
  with 
  a 
  black 
  border, 
  having 
  the 
  nervule-independent 
  

   [disco- 
  central 
  nervule 
  — 
  vein 
  5], 
  inserted 
  near 
  the 
  three 
  others, 
  

   opposite 
  the 
  4th 
  inferior 
  [1st 
  median 
  nervule 
  — 
  vein 
  2].

  Guenee 
  remarks 
  : 
  "The 
  species 
  of 
  this 
  genus 
  are 
  of 
  medium 
  

   size, 
  and 
  very 
  similar 
  to 
  one 
  another, 
  so 
  that 
  their 
  varieties
