﻿MALAYAN 
  AND 
  OTHER 
  SPECIES 
  OF 
  CULICOIDES. 
  167 
  

  

  L. 
  velox, 
  a 
  rare 
  species 
  whose 
  habits 
  have 
  not 
  been 
  observed. 
  It 
  would 
  seem 
  that 
  in 
  

   this 
  subfamily 
  only 
  the 
  three 
  genera, 
  Leptoconops 
  (sens, 
  lat.), 
  Culicoides 
  and 
  Lasiohelea, 
  

   are 
  regularly 
  addicted 
  to 
  sucking 
  the 
  blood 
  of 
  mammals. 
  Recorded 
  cases 
  of 
  blood- 
  

   sucking 
  by 
  members 
  of 
  any 
  of 
  the 
  other 
  genera 
  are 
  very 
  few, 
  and 
  some 
  even 
  of 
  these 
  

   can 
  be 
  eliminated. 
  Thus 
  Meigen's 
  statement, 
  repeated 
  by 
  Verrall, 
  that 
  Forcipomyia 
  

   bipunctata 
  bites 
  severely, 
  is 
  certainly 
  due 
  either 
  to 
  an 
  error 
  of 
  identification, 
  or 
  to 
  

   a 
  more 
  or 
  less 
  accidental 
  occurrence 
  ; 
  the 
  species 
  is 
  abundant 
  in 
  this 
  country 
  and 
  

   has 
  never 
  been 
  observed 
  to 
  bite 
  within 
  recent 
  years. 
  Austen's 
  Johannseniella 
  

   fulvithorax, 
  taken 
  in 
  the 
  act 
  of 
  biting, 
  is 
  really 
  a 
  Culicoides, 
  as 
  recently 
  shown 
  by 
  

   Carter. 
  De 
  Meijere's 
  Ceratopogon 
  salmi 
  and 
  C. 
  vexans, 
  described 
  as 
  blood-sucking 
  

   species, 
  appear 
  from 
  the 
  descriptions 
  to 
  belong 
  either 
  to 
  Forcipomyia 
  or 
  Dasyhelea. 
  

   Prof, 
  de 
  Meijere 
  informs 
  me 
  that 
  there 
  is 
  no 
  actual 
  evidence 
  that 
  they 
  suck 
  blood, 
  

   the 
  collector 
  merely 
  supposing 
  them 
  to 
  be 
  capable 
  of 
  doing 
  so 
  on 
  account 
  of 
  the 
  

   structure 
  of 
  their 
  mouth-parts 
  ; 
  the 
  specimens 
  described 
  by 
  de 
  Meijere 
  were 
  mostly 
  

   captured 
  at 
  light. 
  Malloch's 
  record 
  of 
  the 
  biting 
  of 
  Dasyhelea 
  grisea 
  stands 
  alone 
  so 
  

   far 
  as 
  this 
  genus 
  is 
  concerned, 
  and 
  confirmation 
  is 
  desirable 
  ; 
  I 
  have 
  seen 
  no 
  evidence 
  

   that 
  any 
  of 
  the 
  British 
  species 
  of 
  Dasyhelea, 
  one 
  of 
  which 
  is 
  closely 
  allied 
  to 
  D. 
  grisea, 
  

   ever 
  attempt 
  to 
  suck 
  blood. 
  Kieffer 
  has 
  recently 
  published 
  a 
  paper 
  entitled 
  

   " 
  Nouveaux 
  Chironomides 
  piqueurs 
  habitant 
  le 
  Sleswig-Holstein 
  " 
  (Ann. 
  Soc. 
  Sci. 
  

   Bruxelles, 
  Feb. 
  1922) 
  in 
  which 
  various 
  species 
  of 
  Forcipomyia 
  and 
  Atrichopogon, 
  

   as 
  well 
  as 
  Culicoides 
  are 
  described, 
  but 
  he 
  adduces 
  no 
  evidence 
  to 
  show 
  that 
  any 
  of 
  

   the 
  species 
  are 
  actually 
  blood-suckers.
