PROCEEDIXGS OF THE THIKU ENTOMOLOGICAL MEETING 903 



a Catalogue could not be a determinator for all unJcnovsn insects but 

 would provide a very ready help in their determination. 



Such is the ideal Catalogue. It remains to be seen how nearly we 

 call approach such an ideal. It will be by no means easy as things are 

 ,at present, for no one of us has the time or knowledge required for the 

 production of such a Catalogue. But I venture to think that, if we 

 -can enlist the help of specialists who have worked on particular groups 

 of Indian insects, and add their help to our own efforts, we can at least 

 make a start in such an undertaking. 



A certain amount of work in this direction has already been done 

 by myself. 



The Orthoptefa were listed by me in 1912, the list being based on 

 Kirby's Catalogue with additions to that date. This list is at Coim- 

 batore and a little work would bring it up to date. 



Up-to-date card catalogues of the Blattida?, Dermaptera, Isoptera, 

 Odonata, and all Nemoptera (sensn antlquo), prepared by myself, are 

 -at Pusa. 



We have also at Pusa a card-catalogue of addenda to the " Fauna " 

 volumes on Hymenoptera (also listed by Mr. Ramakrishha Ayyar in the 

 Bombaij Journal ; but many of Cameron's names are synonyms and the 

 whole requires careful check) aud also lists of other Indian Hymenoptera. 



The Coleoptera have been partly listed recently in Junk's " Cata- 

 logus Coleopterorum ' and the parts of "Genera Insectorum " and 

 we have a rather incom^ilete card-catalogue of Indian species. The 

 Coleoptera form one of the largest and most difHcult groups for the 

 preparation of a complete catalogue. 



The Macrolepidoptera have been listed in the " Fauna " volumes 

 on moths and the supplementary papers in the Bombay Journal, but 

 numerous additional species have been described iij the Ann. Mag. 

 Nat. Hist., Novitatcs Zoological and other publications and some groups 

 tave been thoroughly revised {e.g., the Sphingida; by Eothschild and 

 Jordan and part of the Noctuidse in the Cat. Lep. Phal.). My own 

 copy of the " Fauna " volumes is partly corrected up to date but requires 

 a good deal of additions to make it complete. 



The Butterflies have been listed in Lepidoplera Ixdica, but 

 numerous additions have been made since then. There should not, 

 however, be any great difficulty in making a complete list of these. 



The Microlepidoptera ~have been listed by myself in a catalogue 

 corrected up to date. 



The Diptera were listed by myself in 1910 and the card catalogue 

 made then is presumably still in the Imperial Pathological Entomo-
