In the Rhynchota the enumeration and description o£ the large 

 collection o£ Homoptera made in the Seychelle Islands by the Percy 

 Sladen Trust Expedition have been completed, but owing to the war 

 the report has not yet been published. The revision and re-arrange- 

 ment o£ the Membracidse has been begun, and large collections o£ 

 Homoptera £rom India have been worked out and new species 

 described, the types o£ which, as a rule, remain in the British 

 Museum. The re-arrangement o£ the important economic £amilies 

 o£ Aphidse and OoccidaB has also been commenced. 



In the Lepidoptera the re-arrangement o£ the Moths o£ the sub- 

 family Arctianse and the family Agaristidge have been completed ; 

 also the sub-family Pyralinse of the Pyralidas. The MS. of Volume 

 II. of the Supplement to the Catalogue of Moths has been completed 

 and most of the plates drawn, and the preparation of the MS. on the 

 sub-family Noctuinse of the Noctuidse nearly completed. 



In the Tineina, the determination and arrangement of unincor- 

 porated material has been continued, and the concluding parts of the 

 Lepidoptera of the Biologia Centrali-America have been published 

 during the year. 



The Henry Doubleday Collections of British and European 

 Lepidoptera were transferred without injury from the Bethnal Green 

 Museum to the British Museum (Nat. Hist.) on 12th August 1915. 



In the Diptera, the collection made by Mr. A. F. R. Wollaston 

 in Dutch New Guinea and numerous and extensive collections of 

 mosquitoes from India, Hong Kong, Sarawak, Natal, Sierra Leone, 

 and elsewhere have been worked out and incorporated ; a large 

 collection of Tabanidse made by Mr. S. A. Neave in Nyassaland, and 

 determined by him, has also been incorporated. Prof. M. Bezzi's 

 work on Ethiopian Syrphidse has been published and the collections 

 belonging to the Imperial Bureau of Entomology with which it deals 

 have been presented to the Museum, and incorporated together with 

 numerous recent accessions of African Syrphidse. The arrangement 

 of the British species of Simulidse and Chironomidse has been com- 

 pleted and the results of a study of the adults of the former family 

 published. A number of undetermined Empidida3 have been sub- 

 mitted to Mr. J. E. Collin, Newmarket, and of Oriental Bombylid?e 

 to Mr, E. Brunetti, Calcutta, for identification. 



Several papers dealing with the collection have been published 

 during the year. 



Imperial Bureau of Entomology. " 



The Entomological Department has continued to benefit greatly 

 by the accession of specimens presented by the Imperial Bureau of 

 Entomology. Most of the specimens were already named, or if new, 

 described before being presented by it, and in this way the Depart- 

 ment secured a considerable number of valuable types.
