labelled, catalogued, and incorporated, and a full account of 

 it will be found under the additions for the year 1912 ; for 

 it was thought convenient that the Collection should be 

 described and acknowledged as a whole under one year, 

 although it had gradually accumulated in the course of eight. 

 It must be added that important instalments, although only 

 a small part of the whole, have been incorporated and 

 acknowledged in some of these years, but form no part of 

 the Collection described on pp. 954-958. A small but impor- 

 tant section of Mr. W. A. Lamborn's Collection from the 

 Lagos district of Southern Nigeria has also been catalogued, 

 and will be found acknowledged under the years 1910-12, 

 and a still smaller proportion of Mr. C. A. Wiggins's Collection 

 from the Entebbe district under the years 1909-11. No 

 specimens of Dr. G. D. H. Carpenter's Collection have as 

 yet been catalogued, although those from the mainland to 

 the north and north-west of the Victoria Nyanza are quite 

 ready for numbering and incorporation, as is also the fine 

 scries from Damba Island in the Lake. It was, however, 

 thought better to keep all these collections separate until 

 Dr. Carpenter's return in the present summer, so that he 

 could the more conveniently study them. Incorporation of 

 these three collections is one of the principal pieces of work 

 for the immediate future. 



A fifth fine collection made by Mr. J. A. de Gaye, F.L.S., 

 F.E.S., of King's College, Lagos, was also presented in the 

 course of 1912, and this will be labelled and incorporated as 

 soon as possible. 



3. Additions to British Collections. 



It will be seen in the list of accessions that an exceedingly 

 important collection of Empidae and their prey, presented 

 by Mr. A. H. Hamm, has now been incorporated. The 

 arrangement follows Mr. Hamm's conclusions upon the cap- 

 ture of prey in relation to courtship, and many interesting 

 and novel results will be found on p. 952, where the Collection 

 is briefly described. Mr. F. C. Woodforde, Col. Yerbury,
