106 ACCOUNTS, ETC., OF THE BRITISH MUSEUM. 



The addition of such a large amount of material has 

 necessitated tlie transference to fresh cabinet-drawers, and 

 the re-arrangement of a great part of the general collection 

 of Lamiidoe. 



A small collection of Coleoptera from Costa Rica, sent by 

 Mons. Pittier, has been named and incorporated. 



In Orthoptera, almost undivided attention has been given 

 to the re-arrangement of the important family Locustidce, 

 which has now been completed in 175 drawers, thus rendering 

 the whole of the order Orthoptera available for study and 

 reference, with the exception of a few drawers of accessions 

 belonging to various families, which are being determined 

 and incorporated as fast as circumstances will permit. 



Mr. Distant's collection of Locustidce from the Transvaal 

 has been examined in conjunction with the re-arrangement of 

 the collection, and the new species described for eventual 

 publication. 



Some small collections of Orthoptera and Neuroptera 

 formed by Sir Harry Johnston in Uganda have been 

 examined ; and reports, including descriptions of new species, 

 have been drawn up. 



No progress has been made in Neuroptera, although there 

 is a considerable amount of material awaiting incorporation, 

 because there is no room in the existing cabinets for 

 expansion, and the assistant in charge of the Orthoptera and 

 Neuroptera has therefore concentrated his work on the 

 former order. For this reason, no descriptive papers relating 

 to the Museum collections of either order have been published 

 during the year. 



A commencement has been made in the re-arrangement of 

 the Hymenoptera in the Museum, and in the sorting and 

 incorporation of the large amount of material that has 

 accumulated during the last few years. Lt.-Col. Bingham 

 has undertaken and commenced the re -arrangement of the 

 ForinicidcB concurrently with the compilation of a volume 

 on Ants, for the series of works on the Fauna of India now 

 being published under the authority of the Secretary of State 

 for India in Council. A few small collections of Hymenop- 

 tera have also been examined and the species determined. 



The specimens of Chalcididce have all been labelled with 

 the names given them by F. Walker when he arranged this 

 collection some forty years ago ; and, whenever possible, the 

 types have been identified and marked. 



In the Diptera the sub-family (Estrince (family (Estridce) 

 has been worked out and re- arranged, and a paper dealing 

 therewith nearly completed for publication. 



A small collection of Diptera made at Ostia in the Roman 

 Campagna by Dr. Sambon, during the expedition for the 

 study of the connection between Mosquitoes and Malaria, 

 despatched in 1900 by the London School of Tropical Medi- 

 cine, ha3 been determined and incorporated, and numeious
