PREFACE. 



THIS book has been written at the request of some of 

 our fellow-workers in India, and, for that reason, we need not 

 apologise for its publication. Its scope is indicated in the 

 title. We have attempted to treat the subject clearly, and to 

 describe the different species in such a manner that any 

 specimen which may be encountered will be easily identified. 

 In our opinion this is the most important requirement of any 

 book dealing with mosquitoes, and, in connexion with it, we 

 venture to hope that our coloured plates, which are strictly 

 accurate in detail, will be found helpful. We are much 

 indebted to our friend Dr. Turkhud, of Bombay, for having 

 drawn them, under our direction, with so much care and 

 skill. 



Although we have not felt able to adopt Mr. Theobald's 

 new classification of " Anopheles," we have given a brief 

 account of his system, and have added, under the title of each 

 mosquito described, the generic and specific names by which 

 the insects are known to him. 



In common with all medical men in the tropics we owe 

 a debt of gratitude to Professor Ray Lankester for having 

 initiated the work of which Mr. Theobald's admirable treatise 

 is the outcome, to Mr. Theobald himself, and to Colonel 

 Giles, I.M.B.
