  The 
  following 
  are 
  preliminary 
  diagnoses 
  of 
  new 
  species 
  of 
  Culicidae 
  from 
  

   Kuching, 
  Sarawak. 
  The 
  specimens 
  were 
  received 
  from 
  Mr. 
  J. 
  C. 
  Moulton, 
  and 
  

   either 
  were 
  collected 
  by 
  the 
  donor, 
  or 
  formed 
  part 
  of 
  the 
  old 
  collection 
  of 
  mosquitos 
  

   in 
  the 
  Sarawak 
  Museum, 
  which 
  was 
  for 
  the 
  most 
  part 
  obtained 
  in 
  the 
  neighbourhood 
  

   of 
  Kuching 
  by 
  Messrs. 
  J. 
  Hewitt 
  and 
  J. 
  E. 
  A. 
  Lewis. 
  The 
  types 
  are 
  all 
  in 
  the 
  British 
  

   Museum.

  Coloration 
  as 
  in 
  A. 
  jugraensis 
  (Leic.)* 
  but 
  the 
  seventh 
  sternite 
  in 
  both 
  sexes 
  is 
  

   clothed 
  with 
  black 
  instead 
  of 
  white 
  scales. 
  Basal 
  lobes 
  of 
  side-pieces 
  of 
  male 
  genitalia 
  

   with 
  a 
  tuft 
  of 
  hairs, 
  whereas 
  in 
  A. 
  jugraensis 
  there 
  is 
  only 
  a 
  single 
  bristly 
  spine 
  in 
  

   this 
  position.

  of

  and 
  almost 
  spine-like

  in

  in

  * 
  I 
  find 
  that 
  I 
  was 
  mistaken 
  in 
  giving 
  A. 
  jugraensis 
  as 
  a 
  synonym 
  of 
  A. 
  joloensis 
  

   (Ludlow). 
  Specimens 
  of 
  the 
  latter 
  sent 
  me 
  by 
  Dr. 
  Ludlow 
  evidently 
  represented 
  only 
  

   a 
  slight 
  colour 
  variation 
  of 
  A. 
  obturbans.
