the collection has proceeded concurrently with it, and is now 

 completed to the end of the important family Tryxalidce. 

 A large number of accessions in Locustidce and other families 

 of Orthoptera have also been determined and incorporated. 



In the Hymenoptera a commencement has been made 

 with the arrangment of the Ichneumonidce, the sub-families 

 Evaniince and G aster uptionince being completed. The 

 Department has had the advantage of the services of Mr. R. 

 E. Turner, who has arranged a portion of the Fossores, viz., 

 the Thynnidce and three genera of ScoliidcB. 



The incorporation of additions to the collection of British 

 Diptera has been continued, and the Dolichopodidce and 

 ETTipidce have been re-arranged, a large series of named 

 specimens presented by Lieut.-Colonel J. W. Yerbury having 

 been incorporated. In the General Collection a portion of the 

 African Tabanidce has been determined, and new species, to 

 be figured in " Illustrations of African Blood-sucking Flies," 

 have been described ; the major part of the family Diopsidce 

 has been worked out ; and species belonging to the genera 

 Lyperosia, Ghrysomyia, Thelychceta, and Alluaudinella 

 (family Muscidce) have been determined. Labels have been 

 prepared for Mr. Terzi's drawings of British Blood-sucking 

 Flies, to be exhibited in the North Hall. A number of 

 collections of Blood-sucking Flies, received during the year 

 from all parts of the World, have been determined and incor- 

 porated, and reports on collections and specimens, believed to 

 be of economic importance, have been furnished to various 

 authorities in India and elsewhere. Information concerning 

 a number of Indian species described by Fabricius and 

 Walker, the types of which are in the British Museum, have 

 been supplied to the Indian Museum, Calcutta. 



The incorporation of Dr. Eger's collection of European 

 Homoptera has been practically completed, and a very large 

 proportion of the Homoptera, described in the " Biologia 

 Centrali-Americana," have been similarly dealt with In 

 the family Fulgoridce, the Derhince, have been re-arranged. 

 Walker's species examined, and a large number of undeter- 

 mined specimens named and incorporated. The Jassidce are 

 in course of arrangement, several of the sub-families having 

 been completed, and some fine collections of Australian 

 Gicadidce have been worked out, and the results published. 



The collection of Acrseine Butterflies has been transferred 

 and re-arranged in the new cabinets, as also the Nympha- 

 line genera allied to Hypolimnas, Salamis, Kallima, and 

 Eiirytela. The re-arrangement of the genus Precis was 

 kindly undertaken by Mr. Guy Marshall, and Mr. H. J. 

 Elwes almost completed the arrangement of the Holarctic 

 Hesperiidm.

 Noctuid sub-family GuouUiance has been published, and the
