ACKNOWLEDGMENTS. 
The sections on Mallopliaga , Diptera , Cimicidce and A noplura have 
been prepared by Mr. Howlett, and the Interlude on Insects and 
Flowers by Mr. I. H. Burkill, Reporter on Economic Products. Illus¬ 
trations marked I. M.N. are from the stock of drawings accumulated by 
my predecessors in the Indian Museum, and used in Indian Museum 
Notes. Those marked F. M. H. have been drawn by Mr. Howlett, 
who has directed the preparation of those illustrating the sections he 
has written. Where not otherwise acknowledged, all the plates and 
illustrations are the work of the Artist staff of this Institute under my 
or Mr. Howlett’s direction ; it may be pointed out that these artists are 
wholly Natives of India, trained in Art Schools of this country ; it is 
needless to emphasise how much the book owes to their beautiful work 
as also to the enterprise of the publishers, who have done the work of 
reproducing all the illustrations in this country. I wish to specially 
express my appreciation of the work of Mr. Slater of the Calcutta 
Phototype Company in the printing of the Colour Plates, carried out 
under very trying climatic conditions and for the first time in this 
country. 
As regards the text, it is, where not stated to be a quotation, orig¬ 
inal ; 1 have acknowledged every direct source of information. The 
book owes something to the work of my staff, since it is based on the 
Pusa collections to which they have contributed specimens and observ¬ 
ations. I have acknowledged this where I can. The volume is 
largely a product of my spare time and scanty holidays ; such a volume 
has been so much required that I have felt that even an imperfect 
one was better than none. Six years ago the work of this section 
commenced and if the book contains imperfections, the critic will recog¬ 
nise that it is based on collections, observations and reference books 
that have been accumulated only in that short time ; I shall be glad if 
those who see omissions or errors will point them out, as it may be that 
a better volume will be built up on this basis, when the study of Indian 
Entomology is further advanced. I may also emphasise the fact that 
where little is said, little is known and the blanks in the book are
