AUTHOR'S PREFACE. 



The present volume, although compiled in India, has been 

 to a considerable extent rewritten since my return to London. 

 Access to tiie Briush Museum collection has enabled me to 

 include a number of additional species, to redescribe many 

 of Walker's spec-ies, and to effect some important alterations 

 in synonymy. 



My tliaiiks are due and are hereby tendered to Dr. N. 

 Annandale, Director of the Zoological Survey of India, 

 (or his kind permission to reproduce many figures from 

 the original blocks made for my papers in the 

 ' Records of the Indian Museum.' This acknowledgment 

 applies not only to the present volume, but also to my 

 previous volume (Brachycera, Vol. I, 1920), from which it 

 was omitted by an unfortunate oversight. Many new figures 

 have been drawn by Mr. Bagchi, of the Indian Museum. 

 Among the Conopidj;: and ffisTKiDJC text-figures 73, 74, 76, 

 77 and 82-85 are by Mr. A. J. Engel Terzi, of London. 

 I am also greatly indebted to Major E. E. Austen, D.S.O., 

 for allowing me the use of his copious manuscript notes on 

 Syrphid.e, which he made some years ago in arranging the 

 Briti.sh Museum collection, and which have proved invaluable 

 iri my revisionary work. 



E. BRUNETTI. 



London, May 1922.
