  The 
  salient 
  points 
  in 
  Pallas's 
  brief 
  description 
  are 
  as 
  follows 
  : 
  — 
  " 
  Cinereus 
  . 
  . 
  . 
  

   Frons 
  hirtella. 
  Antennae 
  triarticulatae 
  ; 
  extremum 
  trinode, 
  basis 
  vero 
  pilis 
  nigris 
  

   subpennata. 
  Palmi 
  [? 
  palpi] 
  nulli 
  : 
  ensis 
  nudus 
  . 
  . 
  . 
  basi 
  pilosus. 
  Pedes 
  

   longissimi, 
  grisei, 
  posticis 
  corporis 
  fere 
  tripla 
  longitudine, 
  praesertim 
  tarsi, 
  elongati. 
  

   Alae 
  lanceolatae, 
  cinerascentes, 
  venis 
  hirsutis 
  ad 
  crassiorem 
  marginem 
  nigro 
  maculatae 
  

   . 
  . 
  . 
  Comes 
  prioris 
  [C. 
  caspius, 
  ? 
  =0. 
  dorsalis, 
  Mg.], 
  rarior 
  red 
  ferocior." 
  

  

  If 
  we 
  make 
  the 
  highly 
  probable 
  assumption 
  that 
  Pallas 
  described 
  the 
  palpi 
  as 
  the 
  

   antennae, 
  and 
  that 
  the 
  latter 
  were 
  either 
  broken 
  off 
  or 
  overlooked 
  in 
  his 
  specimen, 
  

   the 
  above 
  description 
  becomes 
  understandable, 
  since 
  the 
  sentence 
  referring 
  to 
  the 
  

   " 
  antennae 
  " 
  might 
  very 
  well 
  be 
  used 
  to 
  express 
  the 
  appearance 
  under 
  a 
  low-power 
  

   lens 
  of 
  the 
  shaggy 
  palpi 
  of 
  an 
  Anopheles 
  of 
  the 
  Myzorhynchus 
  or 
  Nyssorhynchus 
  

   groups. 
  Although 
  no 
  collections 
  of 
  mosquitos 
  have 
  been 
  made 
  since 
  Pallas's 
  time 
  

   in 
  the 
  North 
  Caspian 
  region, 
  it 
  is 
  unlikely 
  that 
  any 
  species, 
  other 
  than 
  A. 
  sinensis, 
  

   to 
  which 
  the 
  description 
  could 
  possibly 
  apply, 
  occurs 
  there. 
  The 
  name 
  hyrcanus 
  

   will 
  therefore 
  have 
  to 
  be 
  substituted 
  for 
  sinensis.

  subpictus, 
  Grassi.

  rossii,

  G^assi's 
  short 
  description 
  clearly 
  indicates 
  A. 
  rossi, 
  and 
  the 
  fact 
  that 
  he 
  states 
  that 
  

   his 
  description 
  was 
  drawn 
  up 
  from 
  a 
  specimen 
  sent 
  him 
  by 
  Ross 
  from 
  Calcutta 
  

   removes 
  any 
  possible 
  doubt 
  which 
  might 
  exist. 
  It 
  is 
  to 
  be 
  regretted 
  that 
  the 
  operation 
  

   of 
  the 
  rule 
  of 
  priority 
  will 
  prevent 
  the 
  commemoration 
  in 
  zoological 
  nomenclature 
  

   of 
  Sir 
  Ronald 
  Ross's 
  work. 
  

  

  Sfegomyia 
  fasciata 
  var. 
  atritarsis, 
  nov. 
  

  

  Tarsi 
  of 
  fore 
  and 
  mid 
  legs 
  almost 
  entirely 
  black, 
  two 
  or 
  three 
  white 
  scales 
  at 
  the 
  

   bases 
  of 
  the 
  first 
  two 
  joints 
  ; 
  hind 
  tarsi 
  black, 
  with 
  very 
  narrow 
  white 
  rings 
  (narrower 
  

   than 
  the 
  diameter) 
  at 
  the 
  bases 
  of 
  the 
  first 
  three 
  and 
  the 
  last 
  joints. 
  White 
  rings 
  

   on 
  the 
  male 
  palpi 
  narrower 
  than 
  usual. 
  Markings 
  of 
  thorax, 
  abdomen 
  and 
  femora, 
  

   and 
  structure 
  of 
  male 
  genitalia, 
  normal.

  Perhaps 
  the 
  most 
  remarkable 
  colour 
  variation 
  yet 
  recorded 
  in 
  this 
  or 
  any 
  mosquito. 
  

  

  * 
  Dr. 
  G-uy 
  Marshall 
  urges 
  the 
  retention 
  of 
  this 
  name, 
  rather 
  than 
  the 
  adoption 
  of 
  the 
  

   earlier 
  argenteus, 
  Poiret, 
  owing 
  to 
  its 
  wide 
  use 
  in 
  medical 
  literature 
  ; 
  a 
  course 
  which 
  has 
  

   been 
  sanctioned 
  in 
  a 
  few 
  cases 
  by 
  the 
  International 
  Commission 
  on 
  Zoological 
  Nomencla- 
  

   ture. 
  With 
  this 
  suggestion 
  I 
  readily 
  concur. 
  The 
  names 
  Stegomyia 
  and 
  Ochlerotatus 
  

   though 
  used 
  here 
  as 
  genera 
  are 
  to 
  be 
  understood 
  in 
  a 
  subgeneric 
  sense.
