AUTHOR’S PREFACE. 
ay ae 
The preparation of the present Catalogue has extended over several 
years, and it has been laid aside frequently in favour of more urgent 
work; this fact, in conjunction with the wholesale revisions in the 
classification of the Culicidae, rendered necessary in its progress by the 
publication of numerous papers by various authors, and the large 
number of additions and alterations in Cecidomyidae, Chironomidae 
and Tipulidae combining to render the task one of considerable diffi- 
culty. 
It follows that omissions and inaccuracies must have occurred, 
and, as a matter of fact, they are continually coming to light. The 
catalogue is not made up to any particular date, all available names 
being incorporated up to about the middle of 1919, but the printing 
has been a matter of many months and it has therefore been impossible 
to include, even in the ‘‘ Errata and Addenda,” the very latest acces- 
sions to the Oriental Fauna. ‘The Author trusts that these facts may 
be taken into consideration. Readers will very greatly assist him by 
notifying errors as they are discovered.
