164 ACCOUNTS, ETC., OF THE BRITISH MUSEUM. 



to deal with the matters requiring attention. Mr. G. H. 

 Grosvenor's services were continued until, at the end of April^ 

 he left in order to take advantage of a Carnegie Research 

 Studentship, which enabled him to go to the United States to 

 continue his studies there, and to become more thoioughly 

 acquainted with the practical side of the subject. Fortunately 

 the services of Mr. H. Maxwell-Lefroy, Imperial Entomologist 

 to the Government of India, were just then available, and were 

 secured in the interests of the Museum for the rest of the year. 

 Although Mr. Lefroy was unable to give as much time as could 

 be wished, his wide knowledge and great practical experience 

 were of considerable value not only in dealing with inquiries 

 that came in from time to time, but in all matters relating to 

 the arrangement of the economic collections, and to the 

 organisation and future development of the work. 



The card-index giving references to all the chief insect pests^ 

 of the world and to the literature bearing upon them, which 

 was begun by Mr. Grosvenor, was continued by Mr. Lefroy and 

 greatly amplified by the additions which he made to it. In 

 this work he had the assistance of Mr. Lionel Armstrong, whose 

 services were engaged at the beginning of December. 



Inquiries on subjects of economic importance continued to 

 come in from various parts of the world during the year. Many 

 of these, as in previous years, related to the Diptera and more 

 especially to the blood-sucking and other species concerned in 

 the transmission of diseases. 



The following were among the more interesting and 

 important inquiries with respect to the Diptera : — 



1. Determination of Blood-sucking Flies from Sierra 



Leone, Zanzibar, Congo Free State and the Uganda 

 Protectorate. 



2. Tsetse-flies forwarded for determination by the Sleeping 



Sickness Bureau. 



3. The Bite of Glossina fusca, Walk., and that of G. 



moTsiians. An inquiry from the Sleeping Sickness 

 Bureau. 



4. Tsetse-flies and big game in the Transvaal. Information 



sent to the Transvaal Game Protection Association. 



5. Phlebotomus fever at Malta. A request for suggestions 



from Col. Sir David Bruce, C.B., F.R.S. 



6. Hcematopota pluvialis, L., attacking horses near 



Keynsham, Somerset. 



7. Warble-flies and their habits. 



8. The narcissus fly, Merodon equestris, F., bred from 



larvse in bulb of Habranthus. 



9. House-flies as " plagues " at Minehead and Westward Ho. 



10. Swarms of Chloropesta notata in rooms at Hemsby, 

 Norfolk.
