 two early in the present year (Jan., p. 7 ; Feb., p. 98), since

 Curatorship of the Sarawak Museum. 



8. Assistance in Working ont the Material of the 

 Department, 



The lamented death of Col. C. T. Bingham, F.Z.S., F.E.S., 

 deprived this Department of the University of a very kind 

 friend, who has rendered valuable help during many years. 

 At the time of his death Col. Bingham was engaged in 

 working out the very large collections of South African 

 Hymenoptera Aculeata in the Hope Department. 



This material not only includes the species in the 

 large W. W. Saunders Collection, but several more recent 

 accessions of great extent — notably those presented by 

 Mr. Guy A. K. Marshall, Dr. F. N. Brown, Mr. S. A. Neave, 

 and Dr. G. B. Longstaff. The manuscript of Col. Bingham's 

 monograph on " South African Aculeate Hymenoptera in the 

 Oxford Museum " is complete as regards the JMutillidae and 

 Scoliidae and contains part of the Pompilidae. Numbers of 

 new species are described, and obscure and doubtful points 

 cleared up in the paper, which will be of great value to the 

 student of Ethiopian Hymenoptera. 



Colonel J. W. Yerbury very kindly made a special visit to 

 Oxford, as he has done in many previous years, in order to 

 help in the arrangement and determination of the Diptera. 

 He arranged the Cyrtidae, a most interesting and peculiar 

 group of flies specially studied by Professor Westwood. All 

 the types are identified and clearly labelled, and the whole 

 group is now in a most satisfactory condition. Col. Yerbury 

 also examined and confirmed the arrangement of the British 

 species incorporated into the Collection since his previous 

 visit, and himself incorporated the numerous accessions to 

 the general collection of Asilidae. He also brought to- 

 gether the material belonging to the Tabanidae in prepara-
