The economic importance of the insects dealt with here is 

 probably considerable. In both larval and adult stages they prey

I prefer for several reasons that they should go to press 

 in their present condition rather than to wait publication in- 

 definitely, chiefly because the list does not aim at the fullness of

 who have the opportunity of deaUng with these delightful and 

 beautiful creatures in the field, and be of use to them. It is clear 

 that great opportunities await the field naturalist who will devote 

 special attention to this group in India. If these notes prove 

 of use to such I shall have every reason to be gratified.]
