collection of butterflies of the N}'mphalinc genus Charaxes\ 

 the mending,, cleaning, and arrangement in 38 drawers of 

 the Chevrolat Carabidae, from the Van der Poll collection. 

 This last piece of work was especially heavy and of the 

 utmost necessity, for the beetles when purchased were still 

 contained in the original " cartons," with loosely fitting 

 covers. The collection had been exposed to damp, and large 

 numbers of specimens were covered with mould. 



Mr. A. H. Hamm has assisted in the incorporation of 

 Hymenoptera and Diptera, and has printed many large 

 batches of labels, those for the Neave collection being the 

 most important. His chief work, however, has been con- 

 cerned with the fresh accessions as they came in, and espe- 

 cially with the consignment of Mr. W. A. Lamborn from the 

 Lagos district. All of these were at once dealt with, so 

 that they could be studied and the generous donor informed 

 of the results without delay. Other donations which have 

 occupied a large part of Mr. Hamm's time were those pre- 

 sented by Dr. G. B. Longstaff, Mr. F. C. Woodforde, 

 Mr. C. A. Wiggins, the Rev. K. St. Aubyn Rogers, and 

 Dr. R. E. Kunze. He has also continued the readjustment 

 of the specimens in the general collection of butterflies. This 

 great piece of work will be completed in the present year. 



Mr. Joseph Collins has continued the staging of the most 

 delicate insects in the Dale Collection, completing the 

 Hymenoptera Aculeata, Phytophaga, and Parasitica (begun in 

 1909). His most considerable work was the remounting 

 and arrangement in 30 drawers of the second half of the 

 British Carabidae, including about 4,000 specimens presented 

 by Mr. W. Holland. He has also, with other smaller pieces 

 of work, staged the 5-6,000 specimens ^the material of the 

 great Mendelian experiment— presented in 1909 by Mr. L. B. 

 Prout, F.E.S., and Mr. A. Bacot, F.E.S. ; labelled the large 

 Atkinson Collection (chiefly Rhynchota) purchased many 

 years ago"; printed specific determinations and type and 

 co-type labels for large numbers of specimens ; labelled, in 

 large part printed for, and numbered the accessions recorded 

 in the later pages of this Report.
