  [The 
  

   first 
  certain 
  description 
  of 
  this 
  specie? 
  is 
  given 
  by 
  Fabricius, 
  under 
  the 
  name 
  of 
  calo- 
  

   dactylus, 
  in 
  1787, 
  and 
  under 
  this 
  name 
  Hiibner 
  figured 
  its 
  larva 
  and 
  pupa 
  on 
  Ononis 
  

   arvensis. 
  The 
  name, 
  however, 
  had 
  been 
  applied 
  by 
  Schiffermuller 
  and 
  Denis 
  to 
  

   zetterstedtii, 
  Zell., 
  and, 
  as 
  calodactyla, 
  the 
  latter 
  species 
  was 
  figured 
  by 
  Hiibner. 
  

   Two 
  species, 
  therefore, 
  were 
  for 
  a 
  time 
  masquerading 
  as 
  calodactyla, 
  viz. 
  — 
  (1) 
  

   calodactyla, 
  Schiff., 
  Hb. 
  (fig. 
  7)= 
  zetterstedtii, 
  Zell., 
  and 
  (2) 
  calodactylus, 
  Fab., 
  

   Hb. 
  (Larvae, 
  pi. 
  c, 
  figs. 
  a-d) 
  = 
  cosmodactyla, 
  Hb. 
  — 
  acanthodactyla, 
  Tr. 
  Hiibner's 
  

   figs. 
  35-36, 
  named 
  cosmodactyla, 
  are, 
  we 
  think, 
  most 
  probably 
  this 
  species. 
  Treitschke 
  

   applied 
  this 
  latter 
  name 
  to 
  punctidacty 
  la, 
  Haw. 
  = 
  acanthadactyla,Hb., 
  in 
  which 
  he 
  was 
  

   followed 
  by 
  Zeller, 
  Staudinger 
  and 
  Wocke, 
  so 
  that 
  punctidactyla, 
  Haw., 
  was 
  generally 
  

   known 
  as 
  cosmodactyla 
  , 
  Hb. 
  At 
  the 
  same 
  time, 
  this 
  species 
  was 
  referred 
  by 
  

   Treitschke, 
  Zeller, 
  and 
  Staudinger 
  and 
  Wocke 
  to 
  acanthadactyla, 
  Hb. 
  Hence 
  a 
  

   reversal 
  of 
  Hiibner's 
  names 
  took 
  place, 
  which 
  we 
  attempted 
  to 
  put 
  straight 
  in 
  

   1899. 
  Staudinger 
  and 
  Rebel 
  quote 
  this 
  correction 
  in 
  their 
  synonymy, 
  but 
  maintain 
  

   the 
  reversal 
  of 
  the 
  names.] 
  

  

  Description 
  of 
  orig-inal 
  figures. 
  — 
  Fig. 
  35, 
  cosmodactyla. 
  Exp. 
  al., 
  

   20rnm. 
  Forewing, 
  in 
  length 
  9-5inru., 
  in 
  breadth 
  2mm. 
  in 
  middle, 
  3'5mm. 
  

   attornus; 
  costamuch 
  arched 
  throughout 
  ; 
  apex 
  but 
  little 
  produced, 
  not 
  

   sharply 
  pointed, 
  decidedly 
  falcate 
  ; 
  tornus 
  blunt, 
  hardly 
  produced 
  ; 
  

   termen 
  hardly 
  concave 
  ; 
  colour 
  silky 
  rufous-tawny, 
  sparingly 
  marked 
  

   with 
  blackish 
  anteriorly, 
  much 
  obscured 
  by 
  it 
  towards 
  termen. 
  

   Anterior 
  two-thirds 
  of 
  costa 
  blackish, 
  strigulated 
  with 
  ochreous 
  except 
  

   at 
  base 
  ; 
  a 
  narrow 
  oblique 
  whitish 
  fascia 
  at 
  3-5mm., 
  with 
  a 
  broader 
  

   primrose-yellow 
  one 
  at 
  2mm., 
  from 
  apex, 
  and 
  a 
  subapical 
  cluster 
  of 
  

   silvery 
  dots. 
  Middle 
  third 
  of 
  disc 
  with 
  a 
  pale 
  bluish-grey 
  wash 
  along 
  

   centre. 
  Centres 
  of 
  fasciae 
  united 
  by 
  a 
  primrose 
  streak, 
  like 
  an 
  inverted 
  

   dagger-blade, 
  but 
  the 
  termen, 
  though 
  slightly 
  notched 
  in 
  the 
  middle, 
  

   shows 
  no 
  fissure 
  (set 
  specimens 
  resemble 
  Hiibner's 
  figure 
  in 
  this 
  

   respect). 
  Cilia 
  white, 
  tipped 
  with 
  black 
  (? 
  necessary 
  shading), 
  with, 
  

   on 
  dorsum, 
  a 
  roundish, 
  black, 
  projecting 
  scale-tooth 
  rather 
  beyond 
  

   middle, 
  a 
  small 
  blackish 
  spot 
  beyond 
  it, 
  and 
  a 
  larger 
  one 
  at 
  tornus. 
  

   Hindwings 
  silky, 
  rufous-tawny 
  anteriorly, 
  much 
  obscured 
  by 
  blackish 
  

   posteriorly 
  ; 
  third 
  plumule 
  with 
  ochreous 
  dorsal 
  vitta 
  ; 
  upper 
  fissure 
  

   extending 
  almost 
  to 
  middle, 
  lower 
  one 
  nearly 
  to 
  base 
  ; 
  cilia 
  bluish- 
  

   grey, 
  with 
  a 
  mediodorsal, 
  very 
  broad, 
  short, 
  blackish 
  scale-tooth, 
  not 
  

   projecting 
  beyond 
  general 
  line 
  of 
  cilia. 
  Abdomen 
  (suggestive 
  of 
  J 
  ) 
  

   pale 
  rufous-tawny, 
  with 
  a 
  subdorsal 
  row 
  of 
  primrose 
  spots 
  along 
  

   either 
  side. 
  Fig. 
  36, 
  cosmodactyla, 
  represents 
  the 
  imago 
  with 
  the 
  

   wings 
  almost 
  closed 
  over 
  the 
  back, 
  the 
  undersides 
  of 
  the 
  two 
  right 
  wings
