Museum; to Captain James, I.M.S.; Captain Cornwall, I.M.S. ; 
Professor Howard, Professor Poulton, Dr. Sharp, Mr. Verrall, 
Mr. Bradley, Dr. Brabham, Dr. St. George Gray, Mr. Froggatt 
(Government Entomologist, New South Wales), Senhor Moreira, 
Major Ronald Ross, Dr. Lutz, Dr. Chalmers, Dr. Daniels, Dr. 
Bancroft, and others, for the various notes and help general^ 
given me. 
Beyond all I am indebted to Lieut.-Col. Giles, I.M.S., who 
placed all his MS. notes of his admirably compiled work on 
mosquitoes in my hands long before its publication, and who has 
constantly been sending me fresh material to incorporate in this 
work, and notes and papers of great value during his prolonged 
service in India. 
The majority of the plates have been prepared from carefully 
executed drawings by Miss C. Beard, who has devoted much 
time and trouble to this work, which has been one of great 
difficulty. So carefully and beautifully have they been executed 
that scarcely any have had to be returned for alterations. The 
larger and more pronounced Mcgarliincis and a few others have 
been drawn by Miss Fisher with considerable skill. Lastly, I must 
express my thanks for the great trouble taken by Mr. Hammond 
in preparing microphotographs of some hundreds of preparations ; 
the figures of wing scales being collotyped from his negatives, 
whilst most of the wings have also been reproduced from them.
