and he has made considerable progress in transferring the 

 Hesperidse to the new pattern cabinets, at the same time 

 incorporating all accessions. 



During the year 1912 the text of Volume XII. of the Cata- 

 logue of Moths has been passed through the press, and will be 

 published in January, while almost the whole of Volume XIII. 

 has been prepared. The greater part of the Noctuid sub-family 

 Catocalina3 and of the Geometrid sub-family Geometrinse have 

 been rearranged, and the Pyralid sub-family Epipaschianse has 

 been arranged. 



In the Tineina the revision of the Gelechiadse, Ethmiadse, 

 Blastobasidse, Stenomidse, Aegeriadse, Arrhenophanidse, Spar- 

 ganothidse, Eucosmidse, Tortricidte, etc., has been continued in 

 connection with work on the Neotropical genera of these 

 families, and the collection of slides has been augmented. The 

 transference of the British series of Tineina to other cabinets 

 has been completed: the general collection of A.egeriadse has 

 been reset and considerable progress has been made in 

 remounting and rearranging the specimens in new cabinets. 

 Various species of economic interest have been determined. 



In the DIPTERA the working out of the African Tabanidse 

 has been continued, and a considerable amount of new material, 

 presented chiefly by the Entomological Research Committee 

 (now the Imperial Bureau of Entomology), has been incor- 

 porated ; descriptions of the new species have been published 

 in the papers mentioned below. The specimens required by 

 the Museum have been selected from a collection of Tabanidse 

 made several years ago by Mr. S. A. Neave, in N.E. Rhodesia. 



The African Blood-sucking Ceratopogoninse (Family Chiro- 

 nomidse) have been subjected to revision, and descriptions of 

 new species have been published. 



The General Catalogue of Asilidte has been brought down 

 to the year 1910, by the entering of additions. 



A large collection of Tsetse-Fiies (Glossina) from the Congo 

 Free State, received for study from the Musee Royal D'Histoire 

 Naturelle de Belgique, has been determined, and the specimens 

 required by the Museum have been selected. 



A small collection of Diptera from Southern Algeria, 

 recently presented, has been partly worked out, and in 

 connection therewith the material in the Museum collection 

 belonging to the genera Anastoechus, Usia, and Cytherea 

 (Family Bombyliidse) has been re-determined and rearranged. 



A considerable number of accessions belonging to various 

 Families have been determined and incorporated. 



A pamphlet on the House-Fly in relation to disease has 

 been prepared (for publication by the Museum). 



During the year one of the principal additions to the 

 collections has been a further large consignment of British 

 Diptera, under the Verrall bequest, bringing the total up to
