large amount of routine correspondence, which every year 

 becomes more and more onerous and takes up time which 

 should be devoted to more productive work. 



VIII. Insect Survey. 



Steady progress has been made in additions to, and 

 arrangement of, the collection. The whole of the collection 

 of Lepidoptera (including the Micro-lepidoptera) has been 

 overhauled, rearranged and placed in one series, so that all 

 the information on any species or group is now available in 

 one place. The work of rearranging the Coleoptera has 

 been practically finished, and the same has been done in the 

 case of the Orthoptera and part of Rhynchota. The identi- 

 fication of the collection of Diptera was undertaken by 

 Mr. Brunetti during the year and is now in progress. 



The collections continue in good order, but the difficulty 

 of maintaining them, in boxes in open racks in a climate 

 such as that of Pusa, is very great. 



The following collections have been sent out to Special- 

 ists in the groups named and our thanks are due to them 

 for the help afforded : —

named and returned.
