DEPAKTMENT OF ZOOLOGY. 121 



11,650 specimens. Further consignments of Diptera from the 

 Seychelles Islands have been received from Prof- J. Stanley- 

 Gardiner, F.R.S. It- has been impossible, up to the present, to 

 do very much towards the incorporation of these collections. 

 Other large collections which have been received during the 

 year and for the most part incorporated are : — British Diptera 

 from Lieut. -Colonel Yerbury (over 1,000 specimens) ; Culicidse 

 of Malaya from Dr. G. F. Leicester (about 800 specimens, 

 including a large number of types) and Culicidas from the Gold 

 Coast, British East Africa, etc., from the Entomological 

 Research Committee. 



Much time has been given to the expansion of the general 

 collection of Culicidse, and to the determination and arrange- 

 ment of the British Mycetophilidas ; this work is now almost 

 completed. 



Entomological Research Committee. 



Owing to the progress and extension of the important 

 work carried on by the Entomological Research Committee of 

 the Colonial Office, which has now become the Imperial 

 Bureau of Entomology, the two rooms provided for the use of 

 the Scientific Secretary of the Committee and his Assistants 

 have no longer sufficed to meet all their requirements, and the 

 Committee have had to rent additional rooms outside the 

 Museum. Although it is much to be regretted that incon- 

 venience to the Committee should result from lack of available 

 accommodation in the Museum, every effort has been made to 

 facilitate their work, which is still largely conducted within 

 the Museum. 



One result of the active work of the Committee has been 

 the addition to the Insect Room collections of over 80,000 

 specimens during the year, A considerable number of these 

 had been worked out and named before being handed over to 

 the Museum, amongst them being several species of economic 

 importance and a good many valuable type-specimens. The 

 vast majority of the specimens have been set and labelled 

 by the preparators at work in the Insect Room, and have thus 

 been made available for study. A good many have been 

 incorporated in the general collection, and some have been sent 

 to specialists to be worked out. Much of the material 

 presented by the Committee will prove extremely useful for 

 the study of distribution and variation. 



Myriopoda and Arachnida. 



Part of the dry collection of Arachnida has. been arranged 

 and relabelled, and the collections of Ticks have been re- 

 arranged. Numerous accessions have been incorporated into 

 the named collections, and reports on some of the more 

 interesting forms have been published. A model of a Tick 

 (Amblyomma hehrceum) has been prepared for exhibition.
