The necessary arrival of fresh cabinets, and the inevitable 

 spreading out of our crowded collection, as the arrangement 

 proceeds, and as gaps arc filled by the gifts which are con- 

 stantly reaching us from all parts of the world, makes it 

 absolutely necessary that more space should be provided. 

 Immediate needs can be met for some years by the use of 

 a small part of the south end of the space now occupied by 

 the Radcliffe Library, and when a new Laboratory is provided 

 for the Wykeham Professor of Physics ample room will be 

 available. 



In addition to the above-named work, Mr. Holland ar- 

 ranged the fine collection of Cicadidae and Ftdgoridae, and 

 the consignments of Phytophaga (Coleoptera) which had been 

 submitted to Mr. Jacoby. He also worked through the large 

 collection of butterflies brought by Mr. Richard Evans from 

 Siam, and the duplicates from the British Museum of Natural 

 History. 



Mr. Hamilton H. C. J. Druce having very kindly consented 

 to name the Hope Collection of Lycaenid butterflies ("Blues" 

 and their allies), a group upon which he is so distinguished an 

 authority, Mr. Holland arranged examples of all the species 

 ready for conveyance to London. The working out of this 

 difficult group will be of inestimable value to the Hope 

 Museum. 



A large amount of Mr. Holland's time was also occupied in 

 an examination of the whole of the cabinet drawers and boxes, 

 and placing fresh naphthaline wherever necessary. 



Mr. A. H. Hamm has re-set the butterflies of the General 

 Collection as far as the point reached at the close of the year 

 1900, as well as immense numbers of accessions of all kinds. 

 A large amount of printing, labelling, and cataloguing has 

 also been done, as the concluding pages of this Report will 

 indicate. A large number of specimens illustrating biological 

 problems, such as Mimicry, from Mr. Guy A. K. Marshall 

 (Mashonaland), and Mr. R.Shelford (Sarawak, N.Borneo), have 

 been specially set and labelled by Mr. Hamm for the Bionomic 

 Series. In this condition they have been most successfully 

 photographed as lantern illustrations by Mr. A. Robinson.
