DEPARTMENT OF ENTOMOLOGY. 165 



Wollaston Expedition to Dutch New Guinea, and a number of 

 interesting species obtained by Mr. J. C. Moulton on an expedi- 

 tion to Mount Merinjak in Borneo have been the chief additions 

 to the Khynchota received during the year. These collections 

 have all been worked out and the specimens incorporated. 



In the Lepidoptera, the labelling and re-arrangement of the 

 Acr^einse have been completed, and the incorporation of acces- 

 sions in other families has made considerable progress, the 

 Papilionidiie of the Neave collection from British East Africa, 

 the Verity collection, the Heliconinse and Ithomiinse (in part) of 

 the Wickham and Moffat collections, and the Erycinidee of the 

 Godman-Salvin, Hewitson, and Crowley collections having been 

 incorporated as far as cabinet space would allow. 



Volume I. of the Supplement to the Catalogue of Moths 

 was published during the year. The re-arrangement of the 

 moths of the family Amatidse, and of the sub-families Nolinse 

 and Lithosiinse has been completed, as well as the arrangement 

 of the Pyralid?e of the sub-family Endotrichinse. In the 

 Tineina, the revision of the Tineidse, Acrolophidse, and Nemo- 

 phoridse has been continued, together with the Pterophorina, 

 Orneodina, and supplementary work on the Pyralidina (Pyraus- 

 tidae), completing the " Biologia Centrali-Americana." 



In the Diptera, the collection of Asilidge made by Dr. Ernst 

 Hartert in the Western Sahara has been worked out and incor- 

 porated, and a number of small collections from Queensland, 

 Natal, Sierra Leone, Algeria, and the Belgian Congo have been 

 determined. The British Empidse, Bibionidse, SimulidsG, and a 

 large part of the Chironomidse have been re-arranged and 

 expanded, all accessions having been incorporated. Proofs of 

 a volume on the Syrphidse of the Ethiopian Region by Prof. 

 Mario Bezzi, based on material in the Museum collection have 

 been corrected for the press, and the preparation of drawings 

 to illustrate the work has been supervised. 



Imperial Bureau of Entomology. 



The Entomological Department has continued to benefit 

 greatly by the work of the Imperial Bureau of Entomology. 

 As one result of this work, about 60,000 specimens of insects 

 have been added to the Museum collection in the course of the 

 year. Many of these specimens were contained in collections 

 which had been completely named up and the new species 

 described before being presented to the Department, and include 

 a fair proportion of valuable types. It is in every way 

 desirable that nothing should interfere with the close co- 

 operation maintained between the Department and the Imperial 

 Bureau, which is of such great advantage to both, and it is to 

 be hoped that something will be done before long to remove the 

 difficulties experienced owing to the lack of sufRcient accom- 

 modation for the collections and for those who are engaged at 

 work upon them.
