Mr. H. Donisthorpe, and Dr. Longstaff have also continued 

 their generous assistance to this important section of the 

 Hope Department. 



Mr. A. Bacot, F.E.S., who, with Mr. L. B. Prout, F.E.S., 

 presented in 19 10 the material of their great series of breed- 

 ing experiments on Acidalia virgularia, has now generously 

 given the material on which his many important papers were 

 founded. A complete account will appear in a future Report, 

 but in the meantime the specimens are at the disposal of all 

 who desire to study insects or the data of heredity. 



4. Work done by the Staff. 



Early in the year the Department lost the services of 

 Mr. W. Holland, who had been an assistant for nearly 20 

 years. His great services during this period and his 

 generosity to the Collections are described in earlier annual 

 Reports, and now again gratefully acknowledged. 



The work done by Mr. A. H. Hamm and Mr. Joseph 

 Collins is really sufficiently indicated by studying the list 

 of accessions in the later pages of this Report. Furthermore, 

 a great deal of extra labour was thrown upon them by the 

 necessity for the reorganization of the entire Department in 

 consequence of the removal into the Old Radcliffe Library, 

 and by the Entomological Congress. 



The loan collection of British Birds deposited by Mr. F. C. 

 Woodforde has been cleaned, arranged, and provided with 

 labels. A list of several of the rarest species, presented by 

 Mr. Woodforde, will be found on p. 961. 



5. Work on the Collection of Pierinae. 



Dr. F. A. Dixey, F.R.S., has kindly drawn up the following 

 report : — 



"During 1912 several large collections of Pierines were 

 worked out, and no less than 950 specimens incorporated 

 in the Collection. About 500 of these were collected and 

 presented by the Rev. K. St. A. Rogers in British East
