Department of Entomology. 



I. — Arrangement and Conservation. 



Exhibition Series. — No change o£ importance either by additions 

 or alterations has been made in this series during the year. 



Study Series. — Owing to the services rendered by voluntary 

 workers, the progress made in the naming and arrangement o£ the 

 collections has been greater than could have been anticipated in view 

 o£ the loss sustained by the death in March o£ Mr. G. Meade Waldo, 

 Assistant in charge o£ the Hymenoptera, and the absence on War 

 Service o£ so many other members of the Staff o£ the Department. 



In the Coleoptera, the undetermined Carabidse o£ many Oriental 

 genera have been incorporated and arranged after determination by 

 Mr. H. E. Andrewes. Rhynchophora of various groups have been 

 similarly dealt with after having been submitted to Prof. A. Hustache 

 and Mr. Arthur Lea and named by those specialists. The Hawaian 

 Nitidulidse have been incorporated ; and numerous undetermined 

 Cryptophagidae have been named or described by Monsieur Grouvelle. 

 The Endomychidse have been expanded and revised and many new 

 species described. A large number of new species of Rutelinae and 

 Melolonthinse have also been described. The family Meloidae has 

 been in great part revised and the accessions incorporated. The 

 Australian species of Alleculidse have been reincorporated in the 

 collection after determination by Mr. H. J. Carter. The Bruchidse 

 have been revised and re-arranged and the accessions incorporated. 

 By the kind permission of Mr.- Godman, Mr. G. C. Champion 

 has continued to work upon the collections of Coleoptera and in 

 the course of the year has arranged the Heteromera of the families 

 Melandryidse, Scraptiidse, Xylophilidse, and Pedilidse as well as 

 part of the Lagriidge, and has described many new species. 



In the Hymenoptera the arrangement of the Apidse was continued 

 and completed. The Rev. F. D. Morice, who has voluntarily devoted 

 almost the whole of his time to the work, has arranged the British 

 Aculeates and incorporated the Saunders Collection. Mr. Rowland 

 Turner has continued to give his services voluntarily as in previous 

 years, and has completed the arrangement of the Psammocharidse, 

 while Mr. H. St. J. Donisthorpe, another voluntary worker, has 

 arranged the Formicidse of the Palsearctic region. Several small 

 collections sent to him on loan have been named by Prof. T. A. 

 Cockerell. Mr. J. Waterston, of the Imperial Bureau of Entomology, 

 has continued his work in determining and arranging the economi- 

 cally very important parasitic Hymenoptera of the family Chalci- 

 didse. 



In the Rhynchota the revision and re-arrangement of the 

 Membracidse have been completed so far as the Oriental and 

 -Ethiopian regions are represented, and accessions from the Distant
