of the whole of the cabinets, with the object of supplying 

 fresh naphthaline wherever it was needed. He spent much 

 time in the early part of the year in tabulating the localities 

 of specimens in the Pascoe Collection, adding naphthaline as 

 the work proceeded. The yearly work of incorporating the 

 labelled and catalogued accessions has also been heavy in 1909. 



Mr. A. H. Hamm has been chiefly occupied during the 

 year with the great collections of insects presented by Mr. 

 S. A, Neave, Dr. G. B. Longstaff, and Mr. C. A. Wiggins. 

 Advantage was taken of the presence of Mr. Neave in this 

 country to finish the manipulation and labelling of as many 

 of his specimens as possible. Mr. Neave was thus assisted in 

 his work on the collections, while at the same time many 

 difficulties were removed that might have been pressing in 

 his absence. Mr. Hamm also spent a considerable amount 

 of time upon the collection of Picrinae, repinning a large 

 number of specimens to show the under surface and making 

 other changes desired by Dr. Dixey. Another great piece of 

 work was the incorporation of the very fine series of British 

 Diptera presented b)^ Colonel J. W. Yerbury. 



The old specimens in the historic Dale Collection were in 

 a very unsafe condition, being so low on their pins as to be 

 in contact with the bottom of the drawer. Much of Mr. 

 Joseph Collins's time has been employed in staging these 

 specimens and rendering them quite safe. The most delicate 

 insects, the minute moths, were first put right : after these 

 the Diptera and the parasitic Hymenoptera. The specimens 

 of certain groups of the Miers Collection were given full 

 printed labels so that they can be incorporated in the General 

 Collection without losing their identity. The additions to 

 the collections acknowledged in the later pages of this Report 

 sufficiently indicate the large amount of labelling undertaken 

 by Mr. Collins. Printed and written determinations have also 

 been affixed to large numbers of specimens, including the 

 very fine series of British Diptera presented by Colonel 

 Yerbury, and of British Coleoptera presented by Mr. H.St. J. K. 

 Donisthorpc. Mr. Collins also assisted Mr. Hamm in labelling 

 the collections presented by Mr. Neave and Dr. Longstaff.
