viii. Preface 



The l)ihIion;raphy of the subject is already so extensive 

 that the inckision of any at all complete list of publications 

 would add some fifteen or twenty pages to the book, with- 

 out being of any real use to the majority of my readers, 

 who must needs work far from libraries and museums ; 

 while those more favourably situated can easily refer to the 

 very complete lists included in Mr. Theobald's Monograph, 

 as well as those appended to Professor Grassi's " Studi di 

 uno Zoologo sulla Malaria," R. Acad, dei Lincei, Rome, 2nd 

 edit., 1901; to Nuttall and Shipley's "Studies in Relation 

 to Malaria," Journ. of Hygiene, vol. i., Nos. 1, 2, 3 ; and 

 to Dr. Edmonston Charles' " Letters from Rome, with 

 Notes and Postscript by Major Ronald Ross, F.R.S." 

 Liverpool, 1901. Fairly complete systematic references will 

 be found included in the descriptions of each species, in the 

 second part of the book. 



My thanks are also due to Professors Celli and Grassi, 

 for placing the resources of their laboratories at my disposal 

 during a short visit to Rome, and to friends and correspon- 

 dents in all parts of the world, too numerous to mention, 

 who have helped me by sending collections, and by con- 

 tributing even more valuable observations. 



In conclusion, I may mention that I shall always be 

 gi'ateful for specimens of mosquitoes, as well as of ticks, 

 biting insects, and other pests obnoxious to man and 

 animals. The small boxes and materials for collecting, that 

 I used to send to friends good enough to collect, can now 

 be obtained from Messrs. Baker, of 244, High Holborn, but 

 I shall always be glad to do my best to identify specimens 

 sent me, and to help other workers as far as lies in my 

 power.
